ᐅ Underfloor heating – controllable room by room?

Hello everyone,

How well can underfloor heating systems be controlled nowadays?
It is said that it is even possible to regulate them by individual rooms.

If I imagine a single-family house with underfloor heating in the basement, ground floor, and upper floor, is it really possible to control the temperature properly today?
For example, can I set the basement to 19°C (66°F); the kitchen and living room on the ground floor to 21°C (70°F); the hallway, guest bathroom, and study on the ground floor to 20°C (68°F); and on the upper floor, the children's rooms to 21°C (70°F), the bathroom to 23°C (73°F), and the bedroom to 18°C (64°F)?
Is this theoretically possible, and does it work in practice?

I ask because I currently live in an apartment in a multi-family building, and our underfloor heating cannot be controlled properly at all, even though there are sensors and controllers in every room. The building was constructed in 2000 and has underfloor heating in every room except the bedrooms and children's rooms, where conventional radiators are installed. In our case, the underfloor heating is only in the bathroom and living room an – then the temperature in the bathroom and living room is 24°C (75°F) (in the other rooms, a comfortable 20–21°C (68–70°F)) or off, when it is only 19°C (66°F), which is too cold for us. There are no settings in between. We currently only have the underfloor heating on in the bathroom and living room; we do not heat the other rooms.

The heating company has visited several times, but the control still does not work better.

Hello,

That already sounds promising. I hoped there had been a lot of progress...
However, system-related physical limitations cannot simply be ignored! Underfloor heating is inherently slow to respond, that’s just a fact.

They can actually increase significantly with a detached single-family house!

...I’m really confused at the moment. I’ve often read here that the technology (gas, solar, heat pump, etc.) can only be planned once the energy demand is defined. But the energy demand also depends a lot on the planning (which materials are used, how thick the walls are, etc.), or am I wrong?
Completely correct. To accurately determine the actual energy demand, at least the building’s thermal framework must be finalized. Only then can expected consumption costs be estimated.

First, establish a basic framework, then learn about consumption values! As a result, improve the thermal “framework” if necessary!

I understand that the costs for a single-family home will be significantly higher, especially since the living area is much larger!

However, I truly believe we're getting a good deal here, particularly because we have three exterior walls and an unheated basement underneath.

For now, I’ll wait and see how things develop. Next week, we will probably receive the draft contract for the land purchase. Once the notary appointment is finally scheduled, we can take concrete next steps.

Hi,
We have had good experiences with this and since last autumn, we have been using a central heating system that we can control in every room. However, as already mentioned, achieving large temperature differences is not possible. But that doesn’t bother us much.
Best regards
