ᐅ Underfloor Heating, Room Thermostats, and Cold Tiles

Hello everyone,

I have a question for the heating specialists before I bother my heating technician or electrician with my limited knowledge about thermostats.

I have underfloor heating in the house, controlled by room thermostats, and the heating system is a brine-to-water heat pump. Currently, all thermostats are set to about 20°C (68°F), and the room temperature matches that.

However, the floor, especially in rooms with tiles (bathroom, entrance, fireplace room, etc.), feels very cold. Is it possible that the heating system isn’t providing enough flow—at least not enough to warm the floor properly—when the thermostats indicate the room temperature is fine?

Thanks in advance for your answers.

Best regards,
Stephan.

Here’s an example: in the children’s room, the temperature should be between 18 and 20°C (64 and 68°F), the thermostat was set just below 20°C (68°F), but the room temperature was 26°C (79°F)...

Well, that already sounds like it could be the bathroom thermostat that you turned up.

No, the issue with the children's room was before, that's why this whole thing happened.

You do have a warranty, right?

Because something must be wrong!

Quickly contact the heating specialist; they should fix it within 4 weeks—otherwise, it could become problematic for you later.

So, unfortunately I forgot to post the solution to the puzzle here:

Partly, as already suspected, the actuators were swapped—here between the office, child’s room, and bathroom.
In another case, the unit wasn’t connected at all (the ground in the thermostat was not wired).

It really makes you wonder if anything is actually tested nowadays, or if work is only done when the homeowner complains, and then issues are fixed piece by piece...

Well, at least it’s warm now.

Thanks to everyone for the support. When you start completely clueless, all you get are excuses anyway.

Best regards,
Stephan

Good to hear! Even my "remote diagnosis" was accurate.
