You’ve lots of choices for thermostats, especially when you’re buying for a low voltage based heating/cooling system like a central furnace or a boiler or a heat pump based system. But when it comes to choosing a baseboard heater thermostat, you don’t have a wide range of options to choose from. One primary reason is that baseboard heaters are line voltage systems that use direct electricity to heat your rooms.

Energy bills would be high for baseboard heater systems unless you live in a state where electricity costs are very low. About 90% of America is running on low voltage systems and only about 10% of homes are using line voltage systems, like a baseboard heater. Most of the popular thermostat models (like Nest, Ecobee, Emerson Sensi) are incompatible to be used as an electric baseboard heater thermostat (they’re designed for low voltage heating/cooling systems).

In this article, we review the best electric baseboard heater thermostat models out there. We’ve listed the criteria and important points to check before choosing the right model. When it comes to a baseboard thermostat, you can choose from 3 or 4 different types. You can opt for a smart thermostat for baseboard heaters – if you prefer all those high-end features, or you can choose a WiFi-enabled thermostat – if internet-based control is what you prefer. On the other hand, if you don’t have that kind of a high budget for smart/WiFi models – you may opt for a programmable thermostat for electric baseboard heaters. We’ve covered all of them, read on.

The primary reason to buy and install a thermostat in your home is to regulate room temperatures and maintain your comfort levels. However, thermostats also help to cut down energy bills and save money. In fact, investing in the right thermostat is the best way to save energy bills. The money invested in a thermostat will be regained within a few months of installation. Before getting to the reviews section, let’s first see how to choose the right baseboard heater thermostat for your home.

How does a Baseboard Heater Thermostat Work?

A baseboard heater thermostat is a variable swith installed in the electric circuit running to the baseboard heater. A thermostat detects the temperature of the room and regulates the current passing to the heater.

Criteria to Choose the right Baseboard Heater Thermostat

Line Voltage or Low Voltage  – The first and most important point – a “baseboard heater” is a line voltage device. You can’t use a low voltage thermostat (like Nest, Ecobee or other popular models used for furnaces or heat pumps) with a baseboard heater. A line voltage system uses direct line voltage (120 volts or 240 volts) unlike the newer low voltage models (which runs on 24 volts). Line voltage type thermostats are used in older homes and constructions (or in places where electricity costs are very low), especially with the baseboard heaters and electric heaters. The power wires are thicker and they run on 120 volts or 240 volts.

Single Pole or Double Pole – A single pole thermostat connects to the electric mains via 2 wires. You can not shut the power to a single pole thermostat. As an alternative method (to shut power), you can set a very low temperature in the thermostat setting to prevent heat coming up to the room. Double pole thermostat connects to the electric mains via 4 wires. It is possible to shut power to the double pole thermostat system at any desired time. So double pole has an advantage over single pole. You can read our guide on Single Pole vs Double Pole to get more idea.

Smart/WiFi Thermostat or Digital Programmable – A smart thermostat or a WiFi thermostat for electric baseboard heaters has its own benefits over an ordinary programmable thermostat.  A smart thermostat has high end features like voice control,  energy savings (save nearly 10% on annual energy bills), internet based control, geo fencing, auto scheduling and more. On a similar note, a WiFi thermostat can also be controlled via internet using your smartphones (they lack some features of a smart thermostat like geo fencing, voice control etc).

An ordinary digital programmable thermostat don’t have any of these high end features but they still do the job of a thermostat perfectly. The key difference is price! If you don’t have the budget for a smart/WiFi model, always go for the programmable thermostat.

Smart Thermostat for Baseboard Heaters

If you go by data, only about 10% of homes in America relies on high voltage heating. This smaller market size may be one reason that there was no proper “smart thermostat” in the market for line voltage systems like a baseboard heater. New innovative companies like MySa has put an end to this. Now there are smart thermostats for electric baseboard heaters – with all useful features like Energy savings, Mobile App based scheduling, WiFi control, Zoning and a lot more. Let’s see in detail.

Digital Non-Programmable Models

We’ve seen the best of programmable baseboard heater thermostats so far. Now let’s go quickly through ‘Non-Programmable’ models.

The key difference between a programmable thermostat and a non-programmable variant is its way of operation. You can not set schedules and programs in a non-programmable thermostat. Instead, you’d need to set temperatures manually based on the climate conditions every time. I know many families who still prefer “non-programmable” models, as they all like to set their comfort levels manually. The other reason might be budget, as non-programmable thermostats cost less in comparison.

Honeywell Manual Thermostat

FAQ – Frequent Questions

#1 Which one is good – a mechanical or electronic thermostat for baseboard heaters  ?

Mechanical or Electronic – A mechanical thermostat operates with two bonded metals which bend as temperature changes. The switche will turn ON/OFF as the bonded metal bends towards it. Mechanical thermostats lack efficiency and they waste a lot of energy compared to electronic models. The only advantage of mechanical thermostat is its low price. Electronic thermostats come with high precision temperature sensors and fast switching. They sense room temperature and turn ON/OFF the system accordingly. Electronic models are highly effeicient and they save energy. The higher price you pay for an electronic model can be regained within a few months of installation.

#2 Which one of the two – a Programmable or Non-Programmable thermostat?

Programmable or Non-Programmable – The primary difference between the two is that a programmable model can be programmed for 7 days in different combinations like 5-2, 2-2-1, 7 etc. Programmable thermostats adjust itself according to the program. For example, some models have “vacation mode” and if this mode is set, the thermostat will adjust itself and save a lot of energy bills (in vacation mode they work only minimal time preventing freeze). Nonprogrammable models come at a lesser price but they dont have programming capabilities.



  1. I am looking for a thermostat to control a baseboard heater which is located in an unaccessable crawl space. I require a sensor to be located in the space and a thermostat to be outside the space

    • Mathew Kevin Reply

      Hi Tom, Unfortunately there are no baseboard heater thermostats which support additional sensor interfacing. What you can do is, install the thermostat in the nearest possible spot/area where you want temperature to be regulated. You don’t need to place the thermostat exactly near the heater. In most cases, temperature is going to be uniform throughout the home.

      @Kenneth – You can replace an old Federal Pacific thermostat with any double pole line voltage thermostat models.You can choose any of the model listed in this article (which are baseboard heater thermostats) or you can see more options in our article for line voltage thermostats. If you need control with iPhone, choose MySa thermostat (the best smart thermostat for baseboard heaters or radiant heaters). You can also choose any WiFi enabled thermostat (for iphone control) designed for line volt systems.

  3. Nathan Elberg Reply

    two of my baseboard heaters are controlled by knobs on the units themselves, rather than thermostats. I would like to control them with wireless thermostats, rather than have to fish wires through walls. Any recommendations? Thanks.

    • Mathew Kevin Reply

      @Nathan, A wireless thermostat doesn’t actually mean “no wiring” between thermostat and your baseboard heater. A ‘wireless thermostat’ technically means that you can control this thermostat ‘wireless’ using a remote or a mobile app. Keeping this in mind, “MySa” would be a great choice.

  4. Mathew:

    You mentioned in your article that newer models are now low voltage vs. the older electric baseboard heaters that were line voltage of 120 or 240. Can you convert from old 120V to the newer low voltages models? I am assuming the newer ones are much more energy efficient and thus result in a cost savings. We are dealing with models from the 1970s in a cabin that we inherited and running electric baseboard heat in a MN winter is brutal.


    • Mathew Kevin Reply

      Hi Bridget, You can not use a ‘low voltage thermostat’ with a 120/240 volt line volt system like baseboard heaters. The best option you’ve is to use a new model smart thermostat like MySa for baseboard heaters. You can read the review here –

    • Mathew Kevin Reply

      Hi, There are not many models with lock facility. You can opt for a thermostat lock box.

  5. Tari Carnahan Reply

    I have one thermostat that controls two baseboard heaters in different rooms, which means that one room is toasty warm (a room that is not used much) and the other room is still cold. Is there a thermostat which would control both heating units separately or is my best bet to use the wall thermostat for the mail room and to put another thermostat directly on the baseboard heater in the other room?

    • Mathew Kevin Reply

      I assume that your two baseboard heaters are already wired together in the gang box. In such a case, you can use a single thermostat to control the two baseboard heaters. But the catch here is, the “combined wattage” of the two heaters should not exceed the max wattage rating of your thermostat. For example, if you’re buying the Mysa smart thermostat for baseboard heaters (which has power rating 3800 watts), your two heaters combined wattage should be less than 3800 watts. If this criteria can’t be satisfied with any thermostat model, you’d be better off with two thermostats, each for one heater.

  6. I have a Honeywell programmable, essentially the Honeywell TL8230A1003 shown above, for my baseboards. When it’s really cold and sending a lot of juice through to the heaters, the thermostat itself warms up and shuts itself off while the room itself is still cold! Seems like a design flaw; I wonder if some of the units with the control portion hanging off the side address this?

    • Mathew Kevin Reply

      @Christopher – This may be a problem with unit, maybe a defect that has appeared while being in operation for some time. Try replacing this with a new unit. If you prefer a WiFi enabled model, Mysa is a good choice.
