Hello everyone,
We have now been living in our house for six months (KfW 55 standard, although the heating demand is closer to KfW 40) and are really impressed with the indoor climate and comfort provided by the underfloor heating (operated by an air-to-water heat pump). The underfloor heating works flawlessly for us and seems well adjusted, at least the energy consumption is reasonable and the indoor temperatures are almost always comfortable. We don’t have a central or decentralized ventilation system; we ventilate traditionally by opening windows. So far, so good.
The only "problem" is the bedroom (about 17sqm (183 sq ft)): it faces northwest and is not directly heated (the flow temperature is set to zero), because even with the door closed it already gets “too warm.” The temperature in the house is around 21–22°C (70–72°F), which is our preferred indoor temperature. However, in the bedroom, we would like only 16–17°C (61–63°F), since 20°C (68°F) makes the bedding unnecessary 😀 But we simply cannot achieve this… Usually, we ventilate by opening windows crosswise for about an hour before going to bed, which lowers the temperature to around 13–14°C (55–57°F) — actually already too cold — but it quickly rises again and reaches nearly 20°C (68°F) in the morning. This causes waking up at night sweating and almost not needing the blanket. Not very restful… 🤨
Sleeping with the windows open is unfortunately not an option since we need complete darkness and absolute quiet.
How do you handle this? Is it something you just have to accept in extremely well-insulated houses, or how do you get the bedroom cooler? I can’t imagine all new-build homeowners comfortably sleeping at 20°C (68°F), as this doesn’t match the general recommendation for the [oB]optimal sleep temperature[/oB] for adults, which is between 15°C and 18°C (59–64°F).
Thanks in advance!

That's right, it was the same in my condo. At first, the thermostats for the office and bedroom were connected to the wrong actuators.I can rule out that the thermostats are switched, since the other rooms heat normally and are all at the expected temperature. You can also see this at the manifold; the one on the far right is for the bedroom, and except for the initial test run, it has never operated, so it’s still almost pristine, of course 😀

I know the dilemma of only being able to sleep in darkness and quiet, I feel the same way. In our case, we sleep in the attic, and it’s the only room on that floor, so we barely heat that area. In winter, it’s perfect for sleeping: dark, quiet, cool (until summer comes and tropical heat forces us to open the windows, then of course you hear the surroundings again… terrible).
I think in your situation, only a thinner blanket will help. Opening the windows isn’t an option for you (and it wouldn’t make ecological sense if you’re heating the adjacent rooms), and for me, air conditioning is out of the question because of environmental reasons. Give yourselves another 1–2 winters to get used to it. Thanks! It’s reassuring to know I’m not alone in this 🙂 The attic space could be an option for us too, but I don’t really want to “escape” from the nicely furnished bedroom. Then I could just go to the basement, where it’s also cool 😎 I think we’ll just have to get used to it. But in a way, living in a poorly insulated rental had its advantages for the bedroom, at least out of habit 😉

You can already start getting rid of down comforters, terry cloth covers, thick pajamas, etc. Haha, I agree. If I don’t need them in the next few days during temperatures well below zero, everything’s going out.

There are special weighted blankets for covering yourself. As far as I understand, they are supposed to be comfortable to sleep with because of their weight and improve sleep quality, but at the same time not be excessively warm like down comforters.It's crazy what exists 🤨 I just looked it up, and you quickly come across so-called therapy blankets, which are also useful for anxiety or similar conditions. Even without having anxiety, I actually think the idea is pretty good, because these extremely thin and light blankets don’t feel like traditional comforters to me.

Your tacos already look really bad after 6 months..They looked just as bad for me that fast. It gets a bit worse and then I think it stays like that.Mbk84 schrieb:
I also think you just have to get used to it. But out of habit, it was somehow an advantage.A new house means change – including changes in habits. Suddenly, the bed is positioned facing east instead of north, and the window lets in different things than the old one. Outside, there is different light and different sounds.
You can probably get used to different noises at night as well.
Because of COVID-19, we suddenly have early and late shifts instead of regular daytime hours – I never thought I could get up at 5 a.m. :P
By now, we have a Dyson fan, summer and winter duvets, three pillows (two are decorative and get tossed off at night), and we sleep with a tilted window open despite having a mechanical ventilation system with heat recovery. But we make sure to keep the door closed – the rest of the house stays nice and warm. We don’t use roller shutters.
