Underfloor heating: No controllers in rooms on the upper floor

Hello,

the house we want to buy also has underfloor heating upstairs. However, there are no controllers in the individual rooms. The previous owner has so far set the temperature using a central "rotary valve" located behind a hatch in the bedroom.

We want to change that. We would like a controller next to the respective door in each room.

It concerns 4 rooms (1 bedroom, 2 children’s rooms, 1 bathroom). Approximately how much will that cost with a professional?

Material costs?
Installation costs?

Why? Once a underfloor heating system is set at the valves, you actually don’t need individual control anymore.

I speak from experience: I once had a house with valve control in a hatch on the upper floor or in the basement for the ground floor. Everything was fine and great – what’s the point of the effort?

Yes, I just read something like that on the internet. I know about the ERR from an old rental house I lived in (1980 - 1990). So just leave it like that? And what do you do if one room should be cooler than the others (e.g., bedroom)?

Then you set the controller accordingly :)
