Things to Look for Before Buying the Best Thermostat for Radiant Floor Heating

If you are searching for the best thermostat for radiant floor heating, 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 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.

Best Thermostat for Radiant Floor Heating

  1. Electric Radiant Floor Heating: this type of 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.
  2. 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.
  3. Air-Heated Radiant Floors: This type is quite rare, but you can consider it. Generally using solar heating systems, it is a good choice during the day.


  • Programmable or Sensor

Best Thermostat for Radiant Floor Heating

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 sensor-based one. With programmable features, the floor will be heating up at the hour and day that you set it for.

On the other hand, one that has been given a sensor will only turn on when you enter the house. This way, there won’t be any energy loss if you come home later than usual, for example.

Aside from those two, you might also want to consider 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 system 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 floor 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 that you use – and based on that, find a compatible thermostat.

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. You just need to consider your preferences and budget, making your choice based on that.
