We do not recommend the Smart Radiator Thermostats for underfloor heating. The reason is that most underfloor heating systems have backflow valves and our thermostats can only measure the room temperature, not the backflow temperature.
However, if you already have hardwired room thermostats controlling underfloor heating, we can usually replace them with our Smart Wall Thermostats.
Yes, it works. And in the room, the smart thermostat that transmits the temperature to the radiator thermostat.
Caution: If the underfloor heating distributor is in a metal box, there may be problems with the radio to the bridge. Keep the distance short here.
