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!

For comparison:
We live in an end-terrace house, built in 1997.
The radiator in the bedroom is usually set to night mode, which is basically off.
We sleep with the window open and still maintain temperatures between 19 and 21 degrees Celsius (66 and 70°F) in the room. Even when the outdoor temperature is around 0 degrees Celsius (32°F). Of course, if we close the door during the day, the room doesn’t get as warm, but it only gets really cold if we open the windows fully.
What is the downside of ventilating this way and keeping the window open at night?

However, I can actually feel some spots on the bedroom floor that are noticeably warm. Of course, we contacted the plumbing company, and they were here and said the valves are closed and it shouldn’t be happening... but I just can’t shake the feeling that the room is being heated after all. What do you think? Is it possible that the room is only warm because of the heat coming from the living area below (kitchen/dining and living room)?Yes, the likelihood is quite high that this is the case. What is your supply temperature? How warm is the bathroom? Both would have to be fairly high for the bedroom to reach 22 degrees just by heating the ground floor and the bathroom on the upper floor. My guess is simple: you are just using your underfloor heating system along with the heating circuit valve incorrectly.Also, you need to forget about your desired temperatures of 18 degrees in the bedroom and 23–24 degrees in the bathroom.

What’s wrong with airing out the room and leaving the window open at night?Of course, we do ventilate, but the room heats up again very quickly. Leaving the window open at night has several drawbacks. Besides the light (because then the blinds need to be raised a bit), the main issue is the noise. It seems the wind often hits our window, causing the blinds to rattle quite a bit. Also, I don’t have a typical nine-to-five job, so sometimes I come home late at night and like to sleep in until around 9 a.m. But it’s just too noisy here for that.
