This blog post is for individuals who are wanting to buy an best thermostat for hot water baseboard heat and need help picking which one to get. You can count on me to offer you my honest thoughts on several best thermostat for hot water baseboard heat that have been highly suggested by professionals in the field.

So let’s get started!


Using hot water to heat your entire home is the most efficient method. The amount of water that must be heated by the boiler is managed by the thermostat. Baseboard heaters in each room receive hot water, which circulates throughout the house.

Hot water baseboard heating is preferred by most people since it is simple to set up and inexpensive.

It's really as simple as adjusting the thermostat to the temperature you choose for your home's heating.

To help you find the best thermostat for baseboard heat, we've compiled a list of the top thermostats.

Although there are numerous items on the market, we've narrowed it down to the top three that we think are the best of the bunch.

Types of Baseboard Heaters

Baseboard heaters can be either electric or hydronic.

Electric baseboard heaters

There are many types of baseboard heaters, but the most common type is an electric heater that sits in your room and draws in cold, heated air from the surrounding area. It is because they conduct electricity that these fins are so hot.

Density drops as temperature rises. You will see that the air will rise out of the heater and into your home, warming it up. It is simple and inexpensive to install electric baseboard heaters, and they operate silently. Just because they use a lot of electricity doesn't mean they are bad.

Hydronic baseboard heaters

Heating water or oil in a furnace in the basement is the method used by hydronic baseboard heaters. Radiation and convection are two ways in which the fluid's heat is transferred to your rooms by your stove's pipes.

When it comes to hydronic baseboard heaters, the best ones can keep the fluid warm for lengthy periods of time, even after the thermostat shuts them off. Hydronic baseboard heaters, on the other hand, are more expensive and take longer to heat up than electric baseboard heaters.

Low Voltage Vs Line Voltage Thermostats

Low-voltage thermostat

They utilize less power, work at a lower voltage of 30 volts, and have smaller wire than line voltage thermostats. Baseboard heaters, heat pumps, air conditioning, furnaces, boilers, and radiators can all be controlled using these devices.

As long as you're heating your home using ducts, low voltage thermostats should be your go-to solution for controlling the temperature in each room. That's because they utilize very little electricity.

Line voltage thermostat

The bigger wires and higher voltage used by high-voltage thermostats mean that they use more energy than their low-voltage equivalents. Two (or four) broad black and red wires protrude from their face, making it easy to tell them apart from others.

It may require temperature variations of up to 7 degrees Fahrenheit to for these thermostats to respond. It's because of this that hydronic baseboard systems and oil-fired hot boilers have become increasingly popular.

Single Pole or Double Pole

Two wires are used to connect a single-pole thermostat to the electrical grid. There is no way to turn off a single-pole thermostat's power source. As an alternative to turning off the power, you can set the thermostat to a very low temperature to keep the room cool. Four wires are used to connect the thermostat to the electric mains. At any time, the twin pole thermostat system can be disconnected from the power supply. There are advantages to using a twin pole over a single pole, then. For further information, see our comparison of Single Pole vs. Double Pole.

Smart/WiFi Thermostat or Digital Programmable

There are many advantages to using a smart thermostat or a WiFi thermostat for electric baseboard heaters over a traditional thermostat. Voice control, energy savings, internet-based control, geofencing, auto-scheduling, and more are just some of the features of a smart thermostat. You may also use your smartphones to manage a WiFi thermostat, in a similar manner (they lack some features of a smart thermostat like geofencing, voice control etc).

Despite the absence of these high-end functions, a regular digital programmed thermostat accomplishes all of the same tasks as a thermostat. The main distinction is the cost! Always choose a programmable thermostat over a smart or WiFi type if money is an issue.


How do heater thermostats work?

Temperature fluctuations are taken into consideration by mechanical thermostats. They contain a mercury-filled vial and either a metal strip or a bi-metal coil. The mercury-filled vial moves with the strip or coil when the temperature changes.

Heating or cooling will be activated depending on the direction the mercury is flowing in.

What is the best smart thermostat for baseboard heaters?

The Ecobee 3 Lite, in my opinion, is the best smart thermostat for baseboard heaters. The Ecobee app allows you to control its functioning, establish heating schedules, and monitor your energy consumption from anywhere in the world. It's also Energy Star®-certified, which means your heating bills will go down.

On which operating systems does the best smart thermostat app run?

Apple's iOS 10 and Google's Android 5 are the most common operating systems for smart thermostat apps.

What’s the point of using a smart thermostat?

The use of a smart thermostat allows you to program and automate your home's temperature control. Temperatures, scheduling, and other factors can influence this.

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

As the temperature fluctuates, the two joined metals that make up a mechanical thermostat bend. When the bonded metal bends towards the switch, it will turn it ON or OFF. Mechanical thermostats are less energy efficient and waste more energy than electronic thermostats. Mechanical thermostats only benefit from their inexpensive cost. Fast switching and high-precision temperature sensors characterize electronic thermostats. Depending on the ambient temperature, the system is turned on or off. Electronic models are the most energy-efficient options. The additional cost of an electronic variant is quickly recouped after a few months of use.


Despite the fact that there are numerous hot water baseboard heat thermostats on the market today, the three that we have examined are hands down the best.

In addition to saving you money on your utility bills, they'll also make your life a lot more comfortable.

We sincerely hope that after reading this, you have all the knowledge you need to make an educated decision.

Even if you don't wind up purchasing a smart thermostat, be sure it is compatible with your smart home assistant and your smartphone.
