The thermostats placed in your homes are one of those essential devices which not only add comfort but also aids in saving energy. However, finding the best model that gives the best possible results within your budget may seem challenging.

This article aims at reviewing one of the programmable line voltage thermostats which fits the concerns of those who want a basic digital programmable thermostat the ones without the smart features.

In the sparse realm of the 7-day programmable line voltage thermostat that supports electric baseboard heating convector and fan-forced heaters, Aube TH106 model by Honeywell is surely one of the best buys. It looks stylish and has numerous features to program your schedule so that you can have a smile while looking at your energy bills.

What kind of thermostat is it?

As already mentioned, it is a digital thermostat, sans the smart features. You can program the schedule for all the 7 days of the week. For each day, you can set temperature for 4 periods. It also comes with pre-programmed settings, which is aimed to give you the best economic results.

It is two wired device and supports both 120 V and 240V heating unit. Only a few programmable models have 4000watt option, it is one of them.

Let me give you a brief about its other striking attributes, to help you identify it as a good choice

  • Design

Aube TH106 is a rectangle shaped thermostat which looks stylish and blends well with the interiors of any room. It has a digital display screen on its right. It has two sections, one where the screens and control buttons are placed and which can be opened, and the other one has metal fins which act as a heat sink. This actually contributes to its large size.

Talking about its dimensions it has a height of 4.9 inches and width of 5 inch. The depth is about 1.5 inches, which means it won’t stick out of the wall much. Programming control is facilitated through the easy push buttons placed just at the left of the display. The attractive design is one of its peak advantages when compared to other models of the same category.

  • Display

The digital display of this thermostat is quite easy to read and understand. It, however, does not have a backlight, since this one comes with just 2 wires. It shows all the vital information like day and date, set-point temperature, actual temperature, operating mode and period and the live heating power used. You can monitor the power being used for heating through the power heating indicator in the display.

The display is clear and can be comprehended easily once the icons are known to you. Just a glance at it, and you will know in which mode the thermostat is working and at what temperature it has been set.

 

  • Compatibility

 

If you have a 120v or 240 V electric baseboard heater, convector or fan-forced heater, you can install this thermostat. However, since this works on a comparatively low ampere, it cannot operate relays. Also, make sure your house supply runs on 60 Hz frequency. This thermostat is also ideal for radial ceilings.   

  • Accuracy

The accuracy of this thermostat is found to be bang on! This one feature stands out from the rest, as this thermostat has been rated to have the best accuracy in the market among the models of this category. This leads to its amazing on-point temperature control of about (± 0.15-Degree Celsius and 0.27-Degree Fahrenheit). Users have complimented the thermostat a lot for its perfect temperature control.

 

  • Switching sounds

 

Aube TH106 boasts of 100 percent silent switching. Yes, it is free from the annoying clicking sounds that disturb your sound sleep or a peaceful environment. Many thermostats have the drawback of a clicking sound each time the switching happens. The TRIAC switching of this thermostat, however, is smooth and works without a sound. Therefore, it can be placed in your bedrooms, to make your sleep cozy and comfortable in a noiseless way.

 

  • Operating Modes:

 

It has basically two operating modes: Automatic and manual. If you have a proper daily schedule, then programming a schedule that fits your timings would give you the best results. This means that you will be using the automatic mode that makes the thermostat follow a pre-programmed schedule for the 7 days of the week.

Even though the makers boast of providing 4 periods per day, you can actually set only two temperatures per day. This means your room will be nice and toasty in the morning when you wake up, cool when you are away, then again heat up in the evening and then cool down again at night.

However, in the manual mode, you have to set a temperature, and the thermostat would work on that until it is changed by you.

 

 

  • Installation

 

The manual of the thermostat can be used for the installation. It comes with 2 wires, however, with a proper technician,  there is a scope for a 4 wire installation as given in its manual. In case you are not a pro electrician like me, I would definitely recommend you to hire an electrician to install this device. It cannot be installed vertically as it vents out a decent amount of heat on to its metal fins that act as a heat sink.

It comes with aluminium wires though, which may need an antioxidant grease coat on them while hooking if your household wiring is copper.

 

 

  • Power Source

 

This thermostat is powered by batteries and has battery-free back up. This means you need not worry about losing the program to the power outages. Your programmed schedule will be held securely in its memory.

  • Cost

Aube TH106 is certified to be an energy saver thermostat. This implies it would pay for itself in the long run when installed and used properly. The cost is not much, you can check the price at amazon.com.

 

These were some of the features of the 7-day programmable line voltage AUBETH106 thermostat.

To wrap it all up, let me list out the pros and cons and conclude the article.

Pros:

  • Striking Design
  • Sturdy built
  • Useful display, with all the important indicators, especially the power heater indicator
  • Installation is quite hassle-free
  • Accurate temperature control
  • Silent switching

Cons:

  • The display does not have backlighting
  • It comes with only 2 wire, which may not meet the electric code requirements at certain places.
  • Large size
  • Cannot be placed on its side, it needs to be placed horizontally always.

So, this is my review of the AUBETH106, to give a brief idea about the product. Hope you liked the write-up and it helped you in deciding whether the unit should control your heating system.

Are you planning to upgrade your non-programmable line voltage thermostat ( for baseboard heaters) to a brand new programmable model, that not only has the digital features but also is easy on the pocket?  Honeywell is one company, which not only produces reliable but also pocket friendly thermostats of all kinds. Honeywell TL8230A1003 is one of the best selling line volt thermostats (suitable for heating systems like baseboard heaters), that is digital, programmable and affordable. 

Owing the increasing energy rates charged by the companies, we tend to look for economic options. Therefore se days, its always better to opt for a programmable thermostat rather than a non-programmable one.

The digital thermostats have huge effect on reducing your monthly expenses in terms of the energy bills. Regulating the temperatures and using the thermostats only when needed, help a lot in saving energy.  

If you do not prefer the high end digital models that have wi-fi capabilities and just want a basic and simple programmable line thermostat for your electric baseboard, then choosing Honeywell’s TL8230A1003 would be great for you.

Honeywells TL8230A1003 is a line voltage 7 day programmable digital thermostat and is available on many online retail sites like Amazon.

What makes it a fairly good choice?

Before you decide to invest some of your hard-earned money on a thermostat, would it not be nice to know if it suits your desires?

To know you made the right choice you need to know what sort of model it would be like how it would look like, what modes are available etc.

This thermostat comes in with two mounting screws and four solder-less copper wires for connection. It has great easy to use display and a compact design

Let me break down more of its other aspects in points, to give you a concise and clear idea of what to expect of this thermostat.

 

  • Design

 

Talking about the design, it is 4.8 inches in height and 2.8 inches in width. The depth is not much since the front does not stick out from the wall much. It is a vertical thermostat and hence looks compact.

It has non slip rubber buttons on both sides to control and program the settings. These are however small ones, which may cause inconvenience while using them. Another drawback in its design is that these buttons do not have a backlight. Thus, you will find it difficult to change the settings in the dark.

Next the arrangement of buttons has been made in such a way that these are easy to use. However, you must be careful to not to press the “clear” button, accidentally as it is not provided in a separate area. Pressing “clear” button will erase your program, and you will have to set it all over again.

It has a conventional rectangular box design, the ones which you usually see in most of the honey wells thermostat, nothing modern or trendy like its ecobee or nest counterparts

It comes with a digital display which has been elaborately reviewed in the next point.

 

 

  • Display:

 

This thermostat has a large backlit digital display. You will love how clearly it displays the important information, like time, actual temperature and the set temperature along with the mode in which the device is working. Not only this, it also shows a bar graph which indicates how much power is being consumed by your heating/cooling system. It has a green background which makes the numbers easily visible during the night or low light times. A button at the bottom is provided for lighting the back light.

So, if you prefer a large, clear digital display which can be easily read in any lighting condition, this thermostat is right one for you.

 

  • Modes:

 

The thermostat basically has two operating modes: Automatic and manual modes. As already mentioned this one is a 7 day programmable thermostat. This comes with a pre-set schedule. So, in the automatic mode you can either use this schedule or program your own schedule.

 

It provides a completely customizable programming option, with four different periods(sleep, wake, return, away) for a day. You can easily set the program to set the temperature for a whole week, day wise. Even if you are going to be out of town, you can use the “vacay” option. This option, however is not programmable.

 

You cannot set four temperatures for a day even though a day is divided into 4 periods. You can have same temperature for “sleep” and “away” periods and same one for “wake” and “return”. This means for an entire day you can set two temperatures only.

 

In the manual mode, the thermostat would not follow a programmed schedule, rather would just work at the set temperature for the entire day unless changed by you.

 

 

  • Compatibility:

 

This aspect is the most important one to be considered while shopping for a thermostat. You need to know your heating/cooling system before setting out to buy a thermostat. Since all the thermostat do not support all the heating systems, checking compatibitly with your system is a must.

So, if you have 240V line voltage electric baseboards, convectors and fan forced heaters (resistive rated loads) then you can use this thermostat without any apprehension. It is perfectly compatible with these home electric heaters.

 

  • Switch on/off sounds

 

One of the most favourable features of this thermostat is its silent relay. You will be free from the constant ticking sound every time the thermostat changes its temperature settings in the timed modes. This provides a great relief from the annoying sounds during the switch on and off moments. It has been carefully sound proofed for silent operation which has been a common cause of concern in the conventional thermostats.

 

 

  • Installation:

 

Installation of this thermostat can be done by self, if you are familiar with the wiring stuffs. The device comes with a detailed manual that describes the process and precaution to be taken while installing it. However, if you are lay man with not much experience in handling heavy voltage, you must hire a professional to save your life as well as your home wiring. The installation is pretty simple and can be simply done by a professional electrician.

 

  • Cost

 

This is another major factor which decides your thermostat. Cost of this thermostat is fairly attractive, since I find it quite reasonable when comparing it with its nest and ecobee counterparts.

Moreover, it has an accuracy of about ±1 F. This saves up to an additional 10% on your heating bills. So, the money you invest on it will come back to you iver a period of time in the form of savings. Sounds great, right?

 

  • Power Source

 

This thermostat is battery powered but there is no need to change the batteries for a ling time. It does not have battery back up though. This means in the event of a power outage, the programmed settings will get erased and you will have to re-program the temperature settings again when the supply comes back.

 

In a nutshell:

 

These are some of the key features of the thermostat. Hope it helps you decide whether or not to go for this one.

To wrap it up, let me just list out the pros and cons of this product precisely:

Pros:

  • Large, Backlit digital display with all the pertinent information
  • Sleek, vertical rectangular design
  • 7-day programmable option
  • Availability of the manual option, to override the pre-set schedule
  • Silent operation
  • Fits in a decent budget
  • Certified energy saving thermostat, with precision of ±1 F.

Cons:

  • Small rubber control buttons
  • No separate area for the clear button
  • Only two temperature settings available
  • Vacay mode cannot be programmed
  • No batter backup, whole program gets erased in case of a power outage

Plenty of options are there for you in the market when you shop for a digital programmable thermostat. Choose the right one for your heating/cooling systems according to your convenience and budget.

 

 

 

Owing to the growing energy charges by the energy companies, we always try and look for options that save not only energy but also our pockets. Since the cooling heating system of your home uses up most of the energy,  huge electricity bills can be reduced to some extent by using thermostats to control your heating/cooling system.

Thermostats have come a long way from its basic manual operated models to the self learning models.  Here in this article we give you a brief idea about the self learning thermostats.

Self learning thermostats are the programmable smart ones, where the thermostat is smart enough to learn your routine. It then sets the temperature accordingly, without any external assistance. These smart thermostat is a must have if you are a smart home user.   

Read on to get a brief idea about the benefits of a smart self learning thermostat and also discusses some of the models available in the market.

How learning thermostat save energy?

Thermostats are the controllers of your heating/cooling system. A proper control can thus save you a lot of bucks on the energy bills. With all the advancements going on right now, newer and easy to operate models of thermostat have also been introduced in the market. One such thermostat is a self learning thermostat, which learns from your routine and sets the temperature, on-off time accordingly.

Just teach them the temperature you like and the time at which the temperature change is needed, they will automatically chart out a schedule for you.

You can control it from anywhere, all at just a click away on your phone. Thus, you can tell it turn on the heating while on your commute, to enter into a cosy home after a long tiring day at work.

This smart gadget works on machine learning algorithm, this means for the first few days you have to provide a reference data set. Therefore, for these days you will have to program your own schedule. The thermostat will use its learning algorithm to understand your preferences and then will set a schedule that possibly suits you the best.

The energy and effort both are saved in this process. You need not worry about setting a schedule every time you leave or enter the house. Also, since the heating/cooling system is used only when it is needed, it gives an optimal performance.

Other than this, there are other reasons to invest in these smart learning thermostats. Read on to know more.

Benefits of a learning thermostat

Learning thermostats are programmable types which are designed to be clever enough to learn how and when you use your cooling/heating systems.

Since these are upper-end models in terms of cost, you must know their salient benefits before buying one, to make sure you made a fair choice.  

These days, energy conservation is gaining a lot of attention. In view of this, the prime reason which makes a learning thermostat a great investment is its energy saving nature. Since the cooling/heating systems are turned on only when needed, amount of energy wasted is reduced to a great extent. This therefore makes it an eco-friendly energy saver buy.

There are however, other reasons too that make it a lucrative option to make your home smarter.

Remote control option are available in most of the smart thermostats. The thermostat is linked to your phone through internet. Thus, you can change the temperature from any part of the world as long as you have your phone with you. This adds to the convenience factor of these thermostats.

Connecting these thermostats with your smoke or CO alarms improves the safety of your home. They can send alert messages if any thing goes wrong even if you are away from home.

Most of these thermostats can be integrated with smart home applications such as Ivee, life 360, Google home, Samsung Hub etc.

They can adjust and program your schedule automatically, through their auto program feature. So, you can sit back and enjoy in your room, made cosy without any programming hassles.

They are designed to pay for themselves, as they aid in reducing the energy bills and saving decent amount of bucks for you. Hence, they save you from the huge bills that may sum up due to the unnecessary use of your heating/cooling systems.

The Best Learning Thermostat

If we talk about smart thermostats, it is interesting to know how and what gave the idea to its development. Stuart Lombard, the founder of ecobee in an attempt to reduce the energy bills purchased some already available programmable thermostats. When he releasied that these thermostats did not meet his demands, he invented a smart thermostat which was easy to use and saved considerable amount of energy.

Following the launch of smart thermostats by ecobee, many other companies followed its lead. One such company is NESt, who in the year 2011, launched the first self learning thermostat.

Many Models have been launched since then, which may confuse you to pick the right one for you.

Let us give you a short review of two of the leading thermostat models. This may help you in recognising the features to look for when buying a self learning thermostat.

NEST Learning thermostat

 

 

One of the most advanced nest learning thermostat is the nest thermostat E. Here it comes with a large display, far sight screen and wide compatibility with heating systems.

It not only learns and manages your schedule, it also provides temperature suggestions that help your thermostat to be energy efficient.  In fact you are always encouraged to stay in a leaf zone which means you are in the eco safe zone. You earn a green leaf if you stay in that zone. At the end of the month you will get an email telling you how much leaves you have earned. Sounds great, right?

Also, another interesting feature is that, if you wish to set your program manually without following the one set by the thermostat, it will form pattern based on your choices.

 

The true Radiant mode of this thermostat is another very fascinating feature. It learns the time taken by your home to reach a fixed temperature and sets the time accordingly.

The control can be done not only through nest applications, but also through google assistant, and amazon alexa.  Thus you can integrate the learning thermostat with other smart equipment in your home, and control them through a single application on your phone.

Ecobee Smart Thermostats

The Ecobee smart thermostats are not “self learning” like Nest models. But they are definitely “smart thermostats” with all those high end smart features.

I’ve added Ecobee models (Ecobee 4 and Ecobee 3 Lite) in this article as an alternative for Nest models (Nest 3rd Gen or Nest E). For any reason, if you don’t prefer Nest thermostats, Ecobee models prove to be a great choice and they are equally good as Nest by all means.

 

 

This Canadian company have grown over the years since its launch. They were the first ones to introduce the smart thermostats. However, the learning feature were incorporated much later.

ECOBEE4 is its flagship thermostat with amazing features has an in-buit Alexa.

Alexa listens and obeys your commands and sets the temperature accordingly.

Even though you can tell this thermostat to turn on and off along with that to automatically set the temperature, it does not learn your behaviours in the same way a nest learning thermostat does.

It however learns when you are away or home through its home/away option. It uses this mode to set the temperatures accordingly, to give optimum performance.

It can be integrated with many platforms such as HomeKit, SmartThings, Google Assistant, IFTTT, which makes it interconnected with other home appliances at your place.

In case of any malfunction, an alert will be send to your mobile.

It learns you are away or home through the inbuilt occupancy detectors, which detect if someone is at home or the home is vacant. It then adjusts the temperature accordingly.

So, if you are looking for a simpler version, where you only need the thermostat to learn whether there is a person at home or not, this ecobee4 option is better for you.

 

Self learning thermostats are not only eco-friendly but pocket friendly too.

Now that you have an idea of what to expect from it, go add this smart gadget to complete your smart home. Their installation process is also does not require an expertise. Once you start seeing how much you have saved on bills, the initial cost will seem worth.

 

 

 

In this digital era, phones are smart enough to control your HVAC system through a thermostat. Thermostats help in optimally controlling the temperature, thus a proper thermostat control leads to the optimal utilization of the energy, that accounts to a reduction in the energy bills. It also adds to the comfort of the user. Such smart thermostats have numerous features which incorporate some advance options of a smart phone. One of the features is geo-fencing that uses your location from the phone and adjusts the temperature of the thermostat accordingly. In this article, we write about geofencing thermostats – which are thermostats with geofencing feature built in. 

What is geo fencing?

Nowadays owning a smart phone is no big deal and hence most of us have one. The GPS feature of such phones help in tracking your location. This is smartly used by some smart thermostats to deliver optimum performance in terms of reduction in energy consumption through a feature called “geo fencing”.

Geo fencing can be imagined as a virtual fence around your home, the diameter of which you can set.

The thermostats with geo fencing feature, when linked to your smart phone use the GPS to track your position. Once you cross the “virtual” fence, you will be considered to be at home. Now the thermostat will automatically set the temperature according to the input value entered by you.

However, if you are outside the “virtual” fence, you will be considered “out” by thermostat. This will turn down the thermostat and allow the room or home to cool down a bit, which will help in reducing the unnecessary energy usage.   

Why go for a Geofencing Thermostat ?

Well, when you spend some good bucks on a smart thermostat, why not choose a model which gives you comfort and savings at the same time? Let me explain how geo fencing thermostat adds to the luxury of a thermostat.

As already mentioned geo fencing senses your location through the GPS of your phone. Once you enter into your home the thermostat switches on and sets the temperature of your room according to the  pre-programmed schedule.

This means after a long tiring day you would enter into a house that is already cosy and comfortable for you. If you are day in and out all day or if you do not have a fixed schedule, this feature is a must have!

Another benefit is its power saving nature. Once you leave your house, the thermostat moves to away mode, and lets the room’s temperature rise/fall. This means your home HVAC system will work only when it’s needed, thus reducing the power consumption. Obviously, this would be a great relief when you save on your energy bills!

Now that you have clarity about the advantages of geo fencing thermostats, here is a brief review of some of the geo fencing thermostats to help you choose the right one that suits your needs.

Best Geo fencing thermostats:

The year 2011 witnessed the launch of original nest learning thermostat, which was welcomed by the consumers wholeheartedly. It could learn your daily routine and set heating/cooling schedules for you. Even though it was not the first smart thermostat, it sure paved a way for many other companies to launch smart thermostats. Ever since then the companies are striving to make the thermostat smarter with each passing year. Since this article deals with the geo fencing feature, below are reviews of some thermostats focussing on the same.

We have picked three thermostats to review: Nest, Ecobee and Sensi to guide you to select the apt thermostat for your needs.

Nest Thermostats

 

 

If you own a nest smart thermostat which has “Home/Away assist” then your thermostat offers you the geo-fencing feature.  

In the present market scenario, Nest has thermostats which has implemented the geo fencing in the most effective way. Since it supports multiple accounts, it tracks the location of all the members in the house and turns to away mode only when the last person leaves. This is one of the important advantage of this thermostat.

Some of its pros and cons have been mentioned below:

Pros:

  • Supports multiple accounts
  • Moves to “away mode” automatically when the last person leaves the house and changes the temperature automatically. Similarly moves to “Home” mode when it senses someone is nearing your home.
  • Geo-fencing  can be used in the compatible version of nest thermostat which are Nest Learning Thermostat (flagship model) and Nest Thermostat E (budget model)

  Cons:

  • If you do not have a fixed day in and out schedule, there are chances that geo-fencing feature would interfere with the learning capabilities of the thermostat.
  • In case you need to set radius of the geo fence, this thermostat does not have that option.    

Ecobee Thermostats

 

 

Even though Ecobee has some great models when it comes to smart thermostats, its geo fencing feature still needs much improvement. If you own an android phone, it would be easy for you to configure it through the ecobee app itself. However, if you are on iOS device, you have to configure it through the Apple’s own home kit. This means it would require a hub like an iPad, HomePod etc which will be available at home every time.

After configuring, you still might not be satisfied with its performance. Therefore, even ecobee suggests the use of IFTTT and life 360 to gain optimal experience it.

Pros:

  • If you have an irregular schedule, the ecobee geofencing thermostat will work for you.
  • Use of IFTTT and Life 360 gives an optimal geofencing experience.

Cons:

  • It is found to conflict with the schedule programmed by us, thus creating a lot of inconvenience.
  • If you and your phone are out, you will be considered “away” and thermostat will rise/lower the room’s temperature accordingly. Even if there are people inside the room, their motion wont be enough for the thermostat to be in “home” mode.
  • When you return to your home, the thermostat instead of resuming to the pre-programmed schedule, goes into the “hold” mode. This means if you need to go back to the intended schedule, you will have to flip back. This unnecessarily adds an extra step.

 

Emerson Sensi Thermostats

 

The geo fencing feature of the Sensi thermostat is very basic and easy to use. It works as if it has created a virtual circular fence with a radius of 3 miles around your home. This means if you are within this 3 miles, you will be considered “home”, and “away” in case you are out of this radius. All the members have to use the same login credentials, which can be a drawback.

The pros and cons have been listed below:

Pros:

  • This works even if you do not have a fixed day in , day out timings.
  • Pre-programmed schedule is not a necessity for it.

Cons:

  • Does not work with any other home automation devices other than sensi products.
  • Single account has to be shared with all the members of the house.
  • The fixed radius of 3 miles cannot be altered. This means if you are out all day but within these 3 miles, you will be considered home. This in turn would lead to unnecessary energy consumption.

These thermostats have the geo fencing feature. However, if your thermostat does not have this, you can still avail the geo-fencing through various Smart home hubs.

Geofencing using SmartHome Hubs

If you already have smart thermostat which does not have the geo fencing feature, do not worry! You can still avail this feature using various Smart Home Hubs like IFTTT, Life 360, Apple’s HomeKit etc.

So lets start with the basics, what is smart home hub? It is just another version of IoT, where the home equipments are connected with each other through the internet and can be controlled over your phone.

Some of the popular smart home hubs include IFTTT, Samsung smart things, Apple’s home kit etc.

The IFTTT setup is free and simple. It tracks the location of every member through their phone GPS. It also has the option to set multiple fences. It sets the thermostat to “Away” mode, when the last person leaves the home and resumes the program when the first person enters.

It can be used to control any wi-fi enabled thermostat and is very simple to use.

The Apple’s HomeKit on the other hand can be used only for iOS devices. Also it requires a HomeKit hub that remains at home all day and does not support nest products.

Another most recommended SmartHome Hub is the Samsung’s Smart things. It offers all these features as well.

Let me explain how this works by taking IFTTT smarthome hub as an example.

First, you need to download the IFTTT app on your Android/ iOS phone.

Next turn on the location of your phone, and link your thermostat with this app.

Whenever the app senses that you are in the geo fencing radius, it will send a signal to the thermostat to set up the pre-programmed schedule and make your home nice and comfy.

Wrap Up

Geo fencing has indeed transformed the way thermostats are used. With more and more advancements in the technology and companies thriving to make the best use of the smart home and IoT, geo fencing thermostats have a long way to go. They not only add to your comfort but also help you in saving a huge amount of money while optimally using the power for your HVAC systems.

The SmartHome hubs have made it easy to avail the geo fencing feature for your wi-fi enabled thermostat. It means anyone with a smart phone and a wi-fi smart thermostat can enjoy the benefits of the geo fencing thermostats.

#1 Honeywell RTH9585WF

Our #1 choice is Honeywell RTH9585WF – which is one of the best selling WiFi thermostats from Honeywell. You may read our full review of Honeywell RTH9585WF to know in depth about its features, highlights, compatibility and more.

#2 Emerson Sensi ST75

Our #2 choice in Google home compatible WiFI thermostats is Emerson Sensi ST75 – which is a best selling model from the automation expert Emerson. We’ve covered every detail about Emerson Sensi ST75 in our review – where we outline its best features, pros, cons and compatibility with different HVAC systems.

 

“Honeywell” – is a name synonymous with every household in USA, as they have a wide range of home automation products for different purposes. If you recall correctly, Honeywell was the #1 market leader in “thermostats” 10 years ago (for a very long period), until the arrival of Nest and Ecobee. Unlike new generation companies like Nest & Ecobee, Honeywell has a very wide range of thermostat models – serving line voltage heating systems and low voltage systems alike. They also have thermostat models suitable for different budget, starting from as low as 30 USD (basic programmable thermostat). In this guide, we are reviewing “Honeywell RTH9585WF” – which is one of the best selling WiFi thermostat model suitable for low voltage (24 volts) systems like central furnace, boilers or heat pumps.

A little background story!

Honeywell RTH9585WF is actually a newer version of its best selling predecessor Honeywell RTH9580WF, with some added features & a better display. The old version RTH9580WF is still available in the market for purchase, but we believe it would be wise to choose the new version RTH9585WF  (Honeywell might withdraw the old version in future). Lets go deep into the features of Honeywell RTH9585WF.

Honeywell RTH9585WF Thermostat – Review

The key highlight of Honeywell RTH9585WF is its big sized touchscreen display – where you can see the weather data quiet visibly. The big display also facilitates easy on-device programming. Apart from this highlight feature, RTH9585WF incorporates all essential features of a smart thermostat except “self learning” or “auto programming”.

Check Price & View Details

This best selling model has all essential features like #energy savings – where you can expect an annual savings in the range of 10% (on energy usage bills), #WiFi enabled control – where you can control this thermostat from anywhere in the world using mobile app (you can change temperature, programs, create new schedule, get energy reports and more), #voice control  – where you can control the device with your voice through smart hubs like Apple Homekit, Amazon Alexa, Google Home and other popular smart home devices.

Honeywell RTH9585WF has an inbuilt learning technology named “Smart Response” – which controls energy usage very well and keeps your home in a comfortable atmosphere. This algorithm learns from heating/cooling cycles and adjusts itself. This technology also ensures pet safe temperature & operation of the thermostat.

The Design

Popular thermostat models like Nest (T3 and E) and Ecobee (4 and 3 Lite) follows an intuitive design – where they just blend into your room interiors. They are sleek, minimal in size – where one can easily catch the modern, trendy gadget design principles in Nest & Ecobee models. However, our model Honeywell RTH9585WF follows a very conventional design approach – with a box style design, big in size and has a big touchscreen display. The big touchscreen is a plus as it helps people with vision problems to program the device easily. The display background color can also be changed (choose from preset colors ) to match your interiors.

The Touchscreen Display

The display home screen has temperature and humidity (indoor & outdoor separate),  time, and temperature change option (up & down arrows). You can change the temperature setting by touching the up/down arrow. The display has other screens (tabs) namely Fan, Mode & Settings – all of which can be accessed using touch. The display also has an option to see full day weather forecast (5 day forecast is available on mobile app).

Its really a matter of individual preference when it comes to choosing the design. I personally know homeowners who switched from Nest to Honeywell RTH9585WF just because of the bigger display (his wife had vision problems and she preferred a bigger display). If you prefer sleek, minimal design go for the Nest or Ecobee models, whereas if you prefer bigger screen – go for RTH9585WF.

Compatibility of RTH9585WF Thermostat

The golden rule one should keep in mind while shopping a thermostat is ” Check compatibility with your home HVAC system before you add to cart” Any thermostat model, be it Nest or Ecobee or Honeywell is not compatible with all types of HVAC systems. There are different types of HVAC systems in use, where the most common ones are single stage or double stage central furnaces, boilers or heat pumps ( generally known as 24 volt systems or low voltage systems). Read our comprehensive guide on Single stage and Multi stage HVAC systems to gain better understanding.

Note: We’ve crafted a Thermostat compatibility guide – where we cover detailed compatibility data of different popular thermostat models.

Apart from the popular low voltage systems, there are also line voltage systems (running on 120 volts/240 volts). Our model Honeywell RTH9585WF is not compatible for line voltage systems.

The Features of RTH9585WF

As we’ve seen the most important points about Honeywell RTH9585WF, let’s dig deep into all the features of RTH9585WF quickly.

#1 WiFi Enabled – You can control this thermostat using your home WiFi and mobile app (from anywhere in the world). The thermostat should be connected to your home WiFi network or a smart home hub (like Apple Homekit or Amazon Alexa) to facilitate mobile app based control.

#2 Smart Response Technology – is an inbuilt learning algorithm in RTH9585WF, which learns heating/cooling cycles and adjusts itself to serve the right temperature to home inmates.

#8 Auto Updates – for day light savings, 12/24 hour time format and multi language supports.

#9 On Screen Help – The help button on screen helps you solve your problems without surfing over Google.

#10 ENERGYSTAR Certified – which means RTH9585WF is designed on energy saving principles documented by Energystar – the US government backed agency for energy certification.

Comparing RTH9585WF vs RTH9580WF

As I wrote above, Honeywell RTH9585WF is the successor of its best selling WiFi thermostat model Honeywell RTH9580WF (which is still available for purchase). The predecessor is more bulky, follows a conventional boxed design (not sleek, curves are not smoothed); whereas the newer model RTH9585WF is sleek, with smooth design on edges. The key highlight is pricing – where the newer model (RTH9585WF) is available for a better price (with discount offers), where as the older model has no discounts available. Apart from design part, and pricing, all other features are same for both RTH9585WF and the older model RTH9580WF.

Emerson Sensi ST75 vs Honeywell RTH9585WF

Emerson Sensi ST75 – is a great WiFi thermostat model, comparable to Honeywell RTH9585WF by all means. Sensi ST75 follows a much better design approach compared to RTH9585WF, as the model is trendy, stylish, more minimal and sleek than RTH9585WF. The pricing (list price) is almost same for both models, where the discounts offered may vary from time to time.

When it comes to features, Sensi ST75 is the clear winner as it provides “geo-fencing” feature. RTH9585WF has no “geo-fencing” feature. Also, Sensi ST75 claims to provide energy savings in the range of 13% to 23%; whereas RTH9585WF claims nearly 10% energy savings. Sensi ST75 has an HD touchscreen display, whereas RTH9585WF comes with a normal touchscreen display.

Though Sensi ST75 seems to win over Honeywell RTH9585WF, we consider both thermostats are equally good. Honeywell has a high reputation as one of the market leader in thermostats. They make different models of thermostats and serve different types of heating/cooling systems. Emerson, on the other hand has no wide range of thermostat models like Honeywell. Sensi ST75 is their best seller and they keeps on going with it.

If you’ve read our article on “Homekit Thermostats“, you should already know the innovations happening in the home automation industry. The “Big 3” tech giantsApple, Amazon and Google compete each other with its own flagship home automation hubs – Homekit, Alexa and Google Home respectively. If you’re still wondering what is a home automation hub – this is simply a smart device which interconnects different smart gadgets together into a single hub. You can then control each device using your voice or internet (using mobile apps/browser) as you like. In this article we write about Alexa Thermostats – which are basically thermostats compatible with Amazon Alexa.

Nowadays different companies release smart home products compatible with different home automation hubs like Homekit, Alexa, Google Home, Samsung SmartThings, Wink, IFTTT and  more. The most popular thermostat manufacturers like Honeywell, Nest, Ecobee, Lux, Emerson and all others release their new thermostat models compatible with home automation hubs, equipped with voice control and WiFi connectivity. Thermostats are basically two types – low voltage thermostats and line voltage thermostats. In America, about 90% of homes uses HVAC systems that require low voltage thermostats to control them. Only about 10% of homes uses heating systems that require line voltage thermostats. Both types (line voltage and low voltage) has Alexa compatible thermostat models available. Let’s see them in detail.

Let’s first see “Low voltage thermostats” – which are used for heating/cooling systems like central furnace systems, boiler based systems and heat pump based systems. Line voltage thermostats are used for heating systems that use direct electricity like a baseboard heater system.

Alexa compatible Smart Thermostats

“Smart Thermostats” were the pioneer smart home gadgets that came to market from as early as 2011. Nest released the first smart thermostat in 2011. Later companies like Ecobee joined the party. Smart thermostats come packed with smart features that sets them apart from other smart gadgets.

Smart Thermostats are “self learning” – which means you don’t need to program them manually. They learn your habits and lifestyle patterns using artificial intelligence and finally creates a program/schedule (for thermostat) that best suits your lifestyle. The next important smart feature is “high energy savings” – where smart thermostats save energy like no other thermostat models. Another smart thing is “geo-fencing” – where they track homeowners location and act accordingly. If you’re starting to home from office, “geo-fencing” feature in your thermostat will sense this and sets your thermostat to the most comfortable temperature setting. A feature common to all smart thermostat variants is “WiFi connectivity” and mobile app based control from anywhere in the world via internet. You can do things like turn thermostat ON/OFF, change schedule/program, read energy usage reports, get alerts etc on your mobile app.

#1 Ecobee 4 and Ecobee 3 Lite

As a “smart thermostat“, both Ecobee & Nest deserves to be #1 by all standards. In this guide about “Amazon Alexa Thermostats” – we choose Ecobee models as #1 for the reason that it goes well with the “Amazon Alexa” device. Both Ecobee models (Ecobee  4 and Ecobee 3 Lite) are well optimized to work in sync with Alexa. Nest thermostats are compatible with Alexa but the performance is not in tune compared to Ecobee devices. Nest thermostats are better optimized for Google Home and Apple Homekit. If you’re looking for a good smart thermostat that works perfectly with Amazon Alexa, you can choose Ecobee with blind eyes.

Ecobee has two models – Ecobee 4 and Ecobee 3 Lite; where Ecobee 4 – is the full featured model which comes with integrated Amazon Alexa device and an extra room sensor (to manage any hot/cold spots in your home). Ecobee 3 Lite – is the budget model thermostat, which is basically a trimmed version of Ecobee 4. We’ve compared both models in our detailed review of Ecobee 4 and Ecobee 3 Lite.

#2 Nest 3rd Gen and Nest E

Nest Labs were the pioneer in “smart thermostats” and you can read the full review about Nest thermostats in our article. As I wrote above, both Nest and Ecobee make excellent smart thermostats. In the context of this article (on Amazon Alexa compatible thermostats), we consider Nest #2 because Nest thermostat models (Nest 3rd Gen and Nest E ) are not perfectly optimized for Amazon Alexa. They both (Nest models) are compatible with Amazon Alexa but not as optimized as Ecobee models. Nest thermostats are better optimized for Google Home and Apple Homekit.

As we noted above, Nest has two thermostat models – Nest 3rd Gen and Nest E. Out of these two, Nest 3rd Gen is the full featured model with all functionalities of a smart thermostat (including higher compatibility with different type of HVAC systems). Nest E is the budget model – which is basically a trimmed version of Nest 3rd Gen. Read our full review and comparison of Nest 3rd Gen vs Nest E.

WiFi Enabled Alexa Thermostats

If you don’t have the budget for a high end “smart thermostat” but prefer a model that has WiFi based control and voice control through smart home hubs like Homekit or Amazon Alexa, go for a WiFi enabled thermostat with smart hub compatibility. We’ve found Honeywell RTH9585WF and Emerson Sensi ST75 two great choices as a Homekit compatible WiFi thermostat.

#1 Honeywell RTH9585WF

Honeywell RTH9585WF – is one of the best selling WiFi thermostat out there currently. This model is an upgraded version of Honeywell RTH9580WF – which was #1 best seller for a long period of time. This model is compatible with a lot of HVAC system types and you can check the compatibility in our guide.

#2 Emerson Sensi ST75

Emerson Sensi ST75 – is the next best choice in Homekit compatible WiFi thermostats. We’ve covered the model very detailed in our review of Emerson Sensi ST75 – which you should read if you’re considering this thermostat.

HomeKit” – the smart home hub from Apple, is one of the most popular home automation hubs in USA.  The “Big 3” tech giants – Apple, Google and Amazon compete each other in the “smart home” space. Amazon has “Alexa and Echo”, Google has “Google Home” and Apple has “HomeKit”. All of them are equally popular among the folks in USA.

Apple HomeKit is – #1 in popularity among all the 3 models, as it goes well with people owning the “Apple Ecosystem” – with iPhone, iPad, Mac, iTunes and the Apple watch. If you use more than one Apple product, “HomeKit” should be your obvious smart home hub choice. In this article, we write about HomeKit thermostat models – where we list out different thermostats compatible with the Apple HomeKit.  Let’s see the best homekit thermostats for your smart home.

If you read our article – “Types of Thermostats” – you will understand there are different types of thermostats, say low voltage thermostats (like Ecobee, Nest, Emerson Sensi ST75, Honeywell RTH9585WF) and line voltage thermostats (like MySa, Honeywell and more). Thermostats are also classified based on features, say – Smart thermostats, WiFi thermostats, Programmable thermostats and more. Let’s see which of these thermostat models goes well with Apple HomeKit.

Smart Thermostats for HomeKit

In our opinion, there are only two companies that make truly smart thermostats – Ecobee and Nest. Both companies have two variants each; for Nest – Nest 3rd Generation and Nest E, and for Ecobee – Ecobee 4 and Ecobee 3 Lite. Nest and Ecobee models are basically low voltage thermostats suitable for low voltage heating/cooling systems like central furnace, heat pumps and central boilers. They are not suitable for line voltage heating systems like baseboard heaters, forced-fan heaters etc. Currently there is only one company, named MySa – that makes smart thermostat for line voltage systems. All these smart thermostat models works well as “Homekit thermostats” – which means they syncs well with Apple Homekit. Let’s quickly brief through the highlight features of each smart thermostat models for Homekit.

#1 Ecobee 4 & Ecobee 3 Lite

We consider both Nest and Ecobee thermostats equally good by all standards. We’ve reviewed both of them in detail, and you can read them here – Ecobee smart thermostat review and Nest smart thermostat review! We chose Ecobee as #1 because its full featured model (Ecobee 4) comes packed with an extra room sensor (you’ve to buy this room sensor separately for Nest) and Ecobee models don’t require a C-wire (as they have PEN – power extender kit – which can be used if you don’t have C-wire in your home).

Ecobee 4 - View Details

As a smart thermostat, Ecobee thermostats has all necessary features like self learning, high energy savings (Ecobee claims 23% annual energy savings), geo-fencing, WiFi and internet based control, voice control and integration with smart hubs like Apple Homekit, Amazon Alexa, Google Home and more. Ecobee 4 – is the full featured model with built in Amazon Alexa and comes packed with an extra room sensor to manage any hot/cold spots in your home. Ecobee 3 Lite – is the budget model (which is basically a features trimmed version of Ecobee 4) which has all essential features of a smart thermostat but not as good as Ecobee 4.

Ecobee 3 Lite - View Details

The prime difference between Ecobee 4 & Ecobee 3 Lite is compatibility, room sensor and Alexa. Ecobee 4 is compatible with most of the commonly used HVAC systems and supports accessories like humidifiers, ventilators etc. Ecobee 3 Lite does not support accessories and has lesser compatibility compared to Ecobee 4. There is no built in Amazon Alexa for Ecobee 3 Lite and room sensors have to be purchased separately.

#2 Nest 3rd Gen and Nest E

As we wrote above, Nest thermostats are equally good as Ecobee when counted as a smart thermostat. However, the full featured Nest thermostat – “Nest 3rd Generation” – is compatible with higher number of HVAC system types than Ecobee 4 (the full featured model of Ecobee). Nest 3rd Gen – is compatible even with 4H/2C (4 stages of heating and 2 stages of cooling) type multi stage HVAC systems. You may read our thermostat compatibility guide – where we comprehensively cover compatibility of different popular thermostat models.  Both Nest & Ecobee models are compatible with the most commonly used HVAC system types in America – which is either single stage (furnace/boiler) or heat pump based systems. If you’ve a multi stage system, you will have to check compatibility before deciding on your thermostat model.

Note: As we’ve figured out, Nest thermostats goes well with Homekit and Google Home than Amazon Alexa. Nest is owned by Google and they have better tuned their product for Google Home. Nest is also best suited for Homekit and syncs so easily with Homekit (Nest founders are former Apple employees). Nest thermostats are also compatible with Amazon Alexa, Samsung SmartThings and IFTTT and they work well with them. What I speak about is perfect optimisation – and Nest has done that optimization for Google Home and Homekit compared to other home automation hubs.

#3 MySa – Smart Line Voltage Thermostat

MySa – is a smart line voltage thermostat with essential features like energy savings, remote location control via WiFi & internet, mobile app based programming/scheduling , energy reports, geo-fencing and a lot more features. Line voltage systems are basically heating/cooling systems that operate on direct electricity, say 110 volts or 220 volts. They convert electricity directly to heat energy; hence they are usually used in states where electricity costs are comparatively low.

WiFi Enabled Homekit Thermostats

If you don’t have the budget for a high end “smart thermostat” but prefer a model that has WiFi based control and voice control through smart home hubs like Homekit or Amazon Alexa, go for a WiFi enabled thermostat with smart hub compatibility. We’ve found Honeywell RTH9585WF and Emerson Sensi ST75 two great choices as a Homekit compatible WiFi thermostat.

#1 Honeywell RTH9585WF

Honeywell RTH9585WF – is one of the best selling WiFi thermostat out there currently. This model is an upgraded version of Honeywell RTH9580WF – which was #1 best seller for a long period of time. This model is compatible with a lot of HVAC system types and you can check the compatibility in our guide. Read our review of Honeywell RTH9585WF – if you’re interested in this model.

#2 Emerson Sensi ST75

Emerson Sensi ST75 – is the next best choice in Homekit compatible WiFi thermostats. We’ve covered the model very detailed in our review of Emerson Sensi ST75 – which you should read if you’re considering this thermostat.

A “central heating thermostat” – is just the same normal thermostat that is used to control a central heating system. In USA, the two most commonly used type of central heating systems are a boiler or a furnace. A central heating system produces heat at one point (usually setup in the basement area or a furnace room) and distributes heat to the whole building by forced air through duct works (in the case of a furnace), or as hot water/steam through pipes (in the case of a boiler). A thermostat that is compatible with a central heating system can be called – a central heating thermostat; that is a thermostat compatible for a boiler system or a central furnace.

As we’ve mentioned in our other guides, about 90% of homes in USA is using heating systems like a boiler or a furnace or a heat pump. When a central heating system is combined with other systems (like ducts/pipes for heat distribution, thermostats for temperature control, cooling coils) – it forms a complete HVAC system. We’ve published guides featuring Central Furnace Thermostats and Central Boiler Thermostats – both guides covering smart, WiFi and programmable thermostats compatible for central heating systems.

Thermostats for Central Heating Furnace

A furnace based central heating system mainly involves a central furnace setup in one point, and the heat produced in the furnace is distributed through ducts as warm air. Natural gas is the commonly used energy source in a central furnace. In USA, around 49% of homes are powered by natural gas based central heating systems (source). Other than natural gas, Electricity based heating systems (nearly 33% of households), fuel oils (6%) , propane/LPG (5%), wood (2%) are also used as energy source in a central furnace.

The heat produced in a furnace is used to heat the air in a heat exchanger. The warm air is then distributed with help of blowers (forced air), through ducts which are passing through each and every room. A central furnace is relatively cost effective heating system, compared to boiler or other systems.

Thermostats for Boiler Heating Systems

Boilers – as the name implies, uses hot water distribution through pipes installed in different rooms. A boiler unit is setup in one point (usually in the basement) and water is heated to a desired temperature (not really till the boiling point). The hot water is then passed through radiators and pipes installed through out different rooms, where they release heat from hot water while passing. Most commonly, boilers use “natural gas” as fuel source. However, heating oils, electricity, propane/LPG, wood are also used as fuel sources to produce heat.

Boilers are costly to install compared to central furnace heating systems. The reason for high cost is pipes & radiators which have high material cost compared to setting up air ducts. The key advantage of a boiler is the ease of setting up “zoned systems” where each individual rooms can be set as unique zones – which can be controlled using thermostats installed in each rooms.  Central furnace based heating systems are not ideal for setting up zoned systems.

Central Heating Thermostat Types

A handful of choices are available as central heating thermostats – which can be WiFi/Wireless heating thermostats, or smart thermostats, or digital programmable thermostats for central heating systems. Out of these 3 models, smart thermostats are the most modern type with advanced features like self learning, energy savings, internet based control using smartphones, geo-fencing and a lot more. If you’re price conscious, go for a normal digital programmable heating thermostat, which would be budget friendly.

WiFi/Wireless Central Heating Thermostats

We’re living in an “internet connected” era and most people prefer connected smart devices these days. Internet connected devices often provide us with great convenience as they can be controlled from anywhere using smart phone apps. Most of the new generation thermostats like Nest, Ecobee, Emerson Sensi, Honeywell RTH9585WF  – are all WiFi enabled thermostats suitable for any central heating systems (be it a boiler or a furnace). All these wireless central heating thermostats can be connected to your home WiFi and they can controlled from anywhere using the respective mobile apps.

Out of the 4 models listed above, Nest, Ecobee and Sensit ST75 are “smart thermostats” with high end features like energy savings, auto programming, geo-fencing and other useful features. Let’s go through all of them in a nutshell.

#1 Ecobee 4 and Ecobee 3 Lite

We’ve covered full review of Ecobee 4 and Ecobee 3 Lite – where we have detailed features, compatibility, comparison between the two models and a lot other useful information. Ecobee 4 is the full featured model with built in Amazon Alexa, and comes with an extra room sensor to setup zoned system (to manage any hot/cold spots in your home). Ecobee 3 Lite – is the budget model central heating thermostat, which is basically a trimmed down version of ECobee 4.

Compatibility

For Boilers & Furnace – Honeywell RTH9585WF supports upto 2H/2C – that is 2 stages of heating and 2 stages of cooling. Fan is supported for electric furnace models. Other accessories like humidifiers and ventilators are not supported.

In USA, about 90% of homes is powered by a central heating/cooling system like a central furnace or a boiler or a heat pump based system. We write about boiler thermostats in this guide, which are thermostats for controlling central boiler units. A boiler is basically a specially designed water heater – which distributes heat through hot water, while systems like a central furnace distribute heat through warm air. Water is heated in a special chamber of the boiler (which is usually powered by gas or fuel oil) and is then distributed to different rooms of the home via radiators or other heat distribution systems installed. A boiler thermostat helps in controlling the boiler operation, thus maintaining a proper set temperature inside the home.

As I noted above, there are different types of boiler systems like gas-fired boiler, steam boiler, and fuel oil based boiler. Out of these 3 types, gas-fired boiler is the most common one in USA, just like the central furnace based heating systems. You may find steam boilers in some older home constructions, but they are being replaced eventually. Fuel oil based boilers are not used in US homes due to many reasons like foul smell, and efficiency problems. All thermostat models reviewed below are suited to use as a gas boiler thermostat – be it a smart thermostat or a WiFi/Wireless boiler thermostat model or just a normal programmable thermostat variant.

We are here to help you learn more about boiler thermostat models, to find the right one that best fits your boiler heating system.

Smart Boiler Thermostats

Smart Thermostats” are technologically superior, modern, internet connected thermostats which can save energy like no other thermostats. A smart thermostat can save energy in the range of 10% to a max of 23% (under ideal conditions) annually. Apart from energy savings, smart thermostats are built with high end features like control from anywhere using smartphones, self learning (auto scheduling and auto programming), voice control, geo fencing (turning your boiler ON/OFF based on homeowner’s location). Let’s see the best smart boiler thermostats available.

#1 Ecobee 4 & Ecobee 3 Lite

Ecobee smart thermostats are our #1 choice as boiler thermostat. Ecobee has two models in the market, Ecobee 4 – the full featured model and Ecobee 3 Lite – the budget model. Both Ecobee 4 and Ecobee 3 Lite supports 2 stages of heating and cooling (2H/2C) for boilers. They also support 2 stages of forced air cooling (which is known as 2 transformer configuration in boilers). Ecobee thermostats works well with gas boilers and they are a good choice as gas boiler thermostat.

Out of the 2 models, Ecobee 4 – is the full featured model with high end features like built in Amazon Alexa (for voice control) , self learning (auto programming/scheduling), geo-fencing, smart phone based control via internet, and above all energy savings upto 23% (as claimed by Ecobee company).

If you’re interested in Nest thermostat, you should read our review of Nest 3rd Gen vs Nest E – where we compare both models with features and compatibility.

Nest E – the budget model thermostat is a trimmed down version of full featured model. The primary difference being lesser compatibility (Nest E is not compatible beyond 2H/1C – 2 stages of heating and 1 stage of cooling) and build quality (Nest E is built of plastic materials). Apart from this difference, all high end features of a smart thermostat like “self learning”, controlling via smartphones, energy savings, geo-fencing and other features are common for both Nest models.

Wireless/WiFi – Boiler Thermostats

As we’ve seen, “smart boiler thermostats” come packed with a lot of high end features like “self learning”, geo-fencing, high energy savings, WiFi and internet based control and more. All these features are really useful but they come with high price tag as well. If you’re looking for an affordable modern thermostat, then WiFi enabled boiler thermostats are a good choice. Just like smart thermostats for boilers, these WiFi enabled models are good to use as a gas boiler thermostat or as an oil boiler thermostat.

These models will have all those “essential new generation features” like voice control, WiFi connectivity, touch screen, smart home hub integrations, programming/scheduling via mobile apps and a lot other useful features, except high end ones like “self learning” or “auto programming”. The energy saving rate wouldn’t be as high as a smart thermostat but you can expect anything in between 5% and 10%. The key highlight is affordable price compared to a smart thermostat model.
