Electric underfloor heating and radiator in the same room


I just started equip my old house with Tado radiator valves. I do not have thermostats. It has about about 20 radiators all together.

In the bathrooms, we're thinking of installing the Danfoss electric floor heating.

The use-case is to mainly not have cold feet on the stone floors and the floor heating is not meant for heating up the place. The bathroom has an actual radiator with Tado Smart Valve.

Can anyone confirm this will work. Possibly with an Smart Thermostat in bathroom.

I know the danfoss electric floor heating can work with their own thermostat, but i don't want to start using something other than Tado now.

Thanks, Tom


  • @MrTooom The smart thermostat will only measure air temperature. If your Danfoss setup is going to use an NTC sensor to measure floor temperature then you cannot use Tado for control. You’re also limited to 6A power consumption.

    Hopefully you already know that you are limited to 10 smart valves to independently call for heat. You can have more than 10 devices but the extra devices work in tandem with those that call for heat.

  • Hi @GrilledCheese thanks for your reply.

    The 6A limitation I was aware of yes. Here's a link to the floor heating. https://www.hornbach.ch/shop/Elektrische-Fussbodenheizung-Danfoss-Ecmat-300W-0-5x4-m/6479338/artikel.html Not sure it uses such sensor.

    Regarding the 10 smart valves limitation, no I was not aware of that. Haven't read that on the website. That is a bit of a bummer.... I don't want devices to work in tandem, because the radiators are in different rooms, having nothing to do with each other. One could be a bedroom, another an office, hallway, or bathroom. This would mean I have to add a second bridge, and add a second home, which Tado doesn't support in their app....

  • Yes, the device limit is not very clear, but there may be a method to achieve what you want with Tado devices. Direct contact with their technical support team should give a definitive answer.
