Underfloor heating - controllable per room???

Hello,

That already sounds good. I was hoping that a lot had happened there. ...

However, system-related physical disadvantages cannot be "circumvented"! Underfloor heating is simply slow to respond, that's an irrefutable fact!

...And the heating costs are also very manageable....

These can sometimes increase significantly with a detached single-family house!

...I'm really overwhelmed at the moment, I've often read here that you can only plan the technology (gas, solar, heat pump, etc.) once the energy demand is established. But the energy demand also depends heavily on the planning (which materials are used, how thick are the walls, etc.) or am I seeing this wrong?

Absolutely correct, in order to determine the actual energy demand, at least the thermal basic structure of the building must be established. Only then can expected consumption costs be derived.

...I really don't know how to best approach the whole thing right now.

First create a basic framework, then find out consumption values! If necessary, improve the "basic framework" thermally as a result!

Best regards

I already understand that the costs in a single-family house will be significantly higher, since the living area is also much larger!

Although I really believe that we are getting off quite well here, especially since we have three exterior walls and an unheated cellar below.

Ah well, for now, I'll wait and see how everything progresses. Next week we will probably receive the draft contract for the land purchase, and once the notary appointment is finally fixed, we can finally take concrete further steps.

Hi,
We have had good experiences with it and have controlled an FH in every room since last autumn. But as already mentioned, large temperature differences cannot be achieved. However, that bothers us little.
