ᐅ Digital Room Thermostat for Underfloor Heating – Which One to Choose?

Hello everyone,

I am currently looking for digital room thermostats for underfloor heating.
Which ones would you recommend?
It would be great if they are programmable, but this is not absolutely necessary.
Thank you in advance!

We have ones from Rademacher, but you can basically use any brand. On Amazon, there are visually appealing options for about 30-40€ (30-40 USD). Keep in mind that underfloor heating doesn’t work like a regular heater. I also thought programming it accordingly would make a meaningful difference. Honestly, we only program the bathroom to heat up at 4:00 AM so that it’s comfortably warm by 6:00 AM. The rest of the house stays the same all the time.

When we moved in (January), we didn’t heat for two weeks because I wired the thermostats incorrectly. Even after two weeks, the temperature was still around 20°C (68°F) in all rooms. Our thermostats together cost over 1000€ (1000 USD), which was completely wasted money.

Nothing more to add.

Ok. Thanks for your suggestions.
I will take them into consideration.

In new constructions, a heating system is considered "smart" if, once set up, it never needs to be adjusted again. Room thermostats are required by the energy-saving regulations for heated spaces, but they are unnecessary and can be disabled. Alternatively, you can apply for an exemption from the ERR obligation and save money.
My opinion...

This seems to be one of those quotes that everyone has been copying for years, but no one actually puts into practice. I have not read about a single person who has really applied for it and been officially exempted. It’s always just theoretical talk.

In the end, the advisors usually install them themselves anyway (and sometimes deactivate them illegally after moving in) or simply don’t install any, relying on the fact that no one checks.
