Things to Look for Before Buying the Best Thermostat for Radiant Floor Heating
If you are searching for the best thermostat for hydronic radiant floor heatings, then there are
a few factors that you might want to keep in mind. By considering them, you will know exactly what model of thermostat you need to buy.
-
Type of Electric Floor Heating
First of all, you need to consider exactly what type of floor heating you are using. When it comes to radiant floors, you have the following options – and for each of these alternatives, you need to pick a compatible thermostat.
- Electric Radiant Floor Heating
: this type of electric floor heating involves installing conductive pads and cables into the floor, heating the surface above. Since most of these floors involve concrete surfaces, you need to pick a compatible thermostat. - Hydronic Radiant Floor Heating: This is a more cost-effective option. Rather than using conductive cables and mats, hydronic heating runs hot water from a broiler, taking it under the floors.
- Air-Heated Radiant Floors: This type is quite rare, but you can consider it. Generally, using solar heating systems is a good choice during the day.
-
Programmable or Sensor
When picking out a thermostat for electric radiant floor heating, you also need to consider whether you want to go for a programmable option or a floor heat sensor-based one.
The floor will be heating up at the hour and day you set it for, with a programmable thermostat. On the other hand, one that has been given a floor heat sensor will only turn on when you enter the house.
So there won’t be any energy loss this way if you come home later than usual, for example. Aside from those two, you might also want to consider smart thermostats that have an app or voice control.
For example, if your thermostat connects to Amazon Alexa, all you have to do is speak the command, and your smart home radiant floor heating systems will pick it up. It is the perfect choice for those that do not have enough time to spend on settings.
Final Thoughts
Finding the best thermostat for radiant heating might be quite a challenge, considering that there are so many models on the market.
The most important aspect here is to think about the type of floor heating you use – and based on that, find compatible floor heat thermostats.
Other than that, the rest boils down to the features. Some think a simple thermostat with not too many features is a perfect choice.
Others believe a smart floor thermostat is the most efficient. But, again, you need to consider your preferences and budget, making your choice based on that. You can also check our best thermostat for hot water baseboard heat.
