Hello,
we moved into our new build exactly one year ago. We have a KFW55-level house with a ground source heat pump, triple glazing, a ventilation system, and, of course, underfloor heating. We are very satisfied with the house, but there is one thing that bothers me: the temperature in the bedrooms. It is always between 20 and 22 degrees Celsius (68 and 72°F) even though we don’t heat those rooms. On one hand, I find it too warm and would prefer it cooler; on the other hand, I am curious about the cause of this temperature. Of course, we could sleep with the windows open, which we do quite often, but I’m not really happy with that solution.
The thermostat in the room is set to 0 degrees Celsius (32°F). Even the valves for the bedrooms are completely turned off. Only the bathroom on the first floor is heated. However, the bedroom floor feels noticeably warm in some areas. We have contacted the plumbing company, and they confirmed that the valves are closed and said it shouldn’t be happening… but I just have the feeling that the room is still being heated. What do you think? Could it be that the room is just warmed by the heat from the living areas below (kitchen/dining and living room)?
Do you have any ideas what might be causing this? Or is it simply normal in such a setup, where the room below is heated and the house is well insulated, for the bedrooms to be warmer than “before”?
Thank you very much for your suggestions!

If the floor feels warm in certain spots: Could the supply line to the upper floor heating manifold be running under the bedroom floor?
However, even without heating, the bedroom rarely drops below 20°C (68°F). The coldest it got this winter was 17°C (63°F), but that was during a period of several days of continuous frost outside.

You could say it’s physics in action... houses are built to retain heat, and as you can see, it works quite well.Except for @Bookstar.Sorry, had to say that :-p

Sorry, had to say it :-pThe real question is which house is closer to the standard 😀.But regarding the topic: it’s probably an installation error or an unfortunate placement of the heating circuit valve (HKV). Alternatively, the thermostat connections might be reversed. Unfortunately, both happen quite often. At least the second issue is easy to fix. You just have to investigate carefully.
As others have already pointed out, getting below 19 degrees Celsius (66°F) will be difficult due to the type of construction. But you’re quite far from that anyway.
