How to Choose the Best Thermostat for Hot Water Baseboard Heat


Hot water baseboard heating is not one of the most popular ways to heat your house, but not because it can’t. Instead, it’s because people don’t know about it yet.

However, if you look at the most efficient features of a hot water baseboard heater thermostat, you will know for certain that it will last through time.

  • Ease of Installing

By themselves, baseboard heaters can be quite difficult to install, as there are many wires to consider. The last thing you want is a thermostat that is just as difficult to install.

  • Line vs Low Voltage Thermostat

Baseboard heaters generally work with line voltage smart thermostats, which is why you need to choose your thermostat accordingly.

That being said, you may also go for a low voltage option if it was set for that. Although most baseboard heaters operate with line voltage smart thermostats, some work on low voltage systems. 

  • Single vs. Double Pole

Does it connect to 2 or 4 wires? Keep these aspects into consideration when you buy the baseboard thermostat. For example, with a single-pole unit (2 wires), you may not shut its power.

However, you may do so with a double pole (4 wires) smart thermostat. Plus, previous wirings need to be compatible – but you can still wire a single-pole to a double-pole unit.

  • Non-Programmable vs. Programmable

Do you want to set an exact temperature and leave it that way? Or do you want it to remember when you are gone so that you can save power?

In this case, you might want to determine whether you want a programmable or non-programmable thermostat. You can also check out our best pellet stove programmable thermostat.
