We’ve published lots of useful guides on thermostats, all of them helping to find the best thermostat for your home. Ideally, the best home thermostat is the one which keeps your home temperatures comfortable (evenly distributed among all rooms) and saves energy usage at the same time. Every homeowner prefers a smart home thermostat these days, as a smart thermostat brings lots of convenient features with the model – like WiFi connectivity, Geo fencing, self learning of living patterns and auto programming, high energy savings, maintenance alerts of hvac systems and more. The best smart home thermostat will be having all these features built in.

The Best Home Thermostat – Features to Look

As you may already know, there are different variants of home thermostats. As I wrote above, a smart thermostat is the most preferred choice these days by any homeowner. But smart thermostats comes with a high price tag which many people may find out of their budget. If not a smart thermostat, the next best home thermostat choice is a WiFi thermostat model – which has most of the essential features of a new generation smart home gadget. The difference is that a WiFi thermostat (non smart) will not have “self learning” or auto programming feature.

If you’re still out of budget for a wireless/wifi home thermostat, I would advise you choose a normal digital programmable thermostat (7 day or 5 -2 day programmable) – which essentially serves all the basic purpose of a thermostat. Let’s skim through the important features required in a home thermostat.

#1 Energy Savings – A good thermostat should be able to provide a good rate of energy savings – say in the range of 10% or higher. Thermostat makers claim different energy savings percentage for their models, say Ecobee claims upto 23% energy savings, where as Nest claims nearly 13% energy savings. Honeywell and Emerson usually claims near 10% energy savings on annual energy utilisation.

#2 WiFi/Wireless Connectivity – is a very useful feature for home thermostats. You’ll be able to connect the thermostat to your home WiFi and control the device from anywhere using mobile apps. You can turn ON/OFF, change temperature settings, read energy reports, set schedules and a lot more can be performed using your smartphone. We’ve a guide featuring WiFi thermostats – helping you find the best home thermostat with WiFi connectivity.

#3 Scheduling/Programming – is a must for any home thermostat model. The best smart home thermostat models like Ecobee and Nest are “self learning” and they create a schedule themselves (auto programming) by learning your home habits. Most WiFi enabled thermostats (non smart variants) comes with preset schedule for week days and week ends. These schedules can also be programmed based on your preferences. The budget friendly digital programmable thermostat usually don’t have preset schedules but you can program them manually for 7 days or 5 – 2 days (based on the model).

#4 Voice Control – is a nice to have feature in home thermostats. You can control your thermostat using your voice from anywhere in the home – like turn ON/OFF, change temperature and more. These days thermostats are compatible with Amazon Alexa, Google Home and Apple HomeKit – where you can control the thermostat using your voice.

#5 Geo fencing  – is another nice to have feature in any home thermostat. Geo fencing feature identifies the location of homeowner and detects when he/she is away from home. The thermostat will automatically move to “away settings” when homeowner is out of home. On a similar note, the thermostat will automatically adjust temperature in your rooms (to the set/preferred temperature) whenever homeowner is nearing home from an away location.

Top 7 – Best Home Thermostats

We’ve seen those essential features required in the best smart home thermostat. Now let’s see which all models offer those crucial features. Before we start, let’s classify thermostat models into 3 variants – 1) Smart Thermostats 2) WiFi Thermostats and 3) Digital Programmable Thermostats.

  1. Smart Thermostats – Self Learning/Programming, WiFi Enabled, Voice Control, Geo fencing and Smartphone app
  2. WiFi Thermostat – All the features of smart thermostat except “self learning/programming”
  3. Digital Programmable – No WiFi, No Self learning or any  such features. The device will be programmable on screen.

So why do we gave rank 1 to Nest learning thermostat? Lets have a look.

Advantages of Nest WiFi learning thermostats.

  1. Learning Capability– The best and unique feature of Nest thermostats. It does have the ability to learn your behaviors and to respond with respect to it. Nest take 1 week to analyze your common behaviors. For example, if you are setting 23 degree Celsius or 73 degree Fahrenheit during 10 pm every day(before sleep) and turning up to 82 degree F when you wake up at 7 am, Nest will learn and store it. No matter if you do something unusual(like turning the temperature down/up drastically). Nest is very intelligent that it doesn’t record such kind of unusual activity. Nest adapts itself to your most preferred settings. In short, nest makes your life damn easy, it acts as a personal assistant for you.

Unlike the conventional designs of the other thermostats, Nest, with a round and shiny look, appears like a super cool gadget for your house. It will be a decoration for your house.
  3. Easy Installation – The nest claims that you can install the thermostat within 30 minutes. Well, it depends on how much expert you are in the installation and for sure you can definitely install it in 30 minutes. It doesn’t need the C wire , you can leave it free(according to Nest). The detailed pdf/video installation guide can be found in the nest website. Also you can hire certified processionals from their website for installation.
  4. No need of batteries – You can save some bucks, replacing the batteries every year.
  5. Ease of use – The usage is pretty easy and convenient. You will find Nest very easy and user friendly to program and change settings
  6. Airwave algorithm– Nest only have the airwave algorithm which gives you more savings. As far as an AC is concerned, the majority of the energy is consumed by fan and compressor. Of which, compressor eats most of the energy. Even if the compressor is turned off, the compressor coils will stay cool for 5-9 more minutes. Nest’s airwave algorithm uses this logic save more energy for you. It turns off the compressor 5-6 minutes before the ac achieves your targeted temperature. In short, you save the energy running the compressor for 5 minutes
  7. Unlimited time Periods – You can have unlimited time periods for nest thermostats while it is just 4 for honeywell and ecobee.
  8. Awesome monthly report and the leaf badge– The monthly reports of nest are simply incredible, it will also give you a leaf badge if your savings were above the benchmark. This leaf badge is very interesting, it will show you how much leaves you earned comparing to previous months as well as all the nest thermostat users around the world. You can compare your savings amount comparing to the other Nesters. nest leaf
  9. Google’s acquisition of Nest -It was a big news recently that Google acquired Nest. With this acquisition, it is sure that more exciting features would be implemented to Nest. This should also increase the resale value of Nest thermostats.

Biggest Disadvantage

  • The biggest disadvantage of Nest is its temperature swing of +/- 3 degrees . Well , the company does say a temperature swing of 1 degree, but it is generally said that Nest does have a swing of 3 degrees.
