Hello,
a similar thread has already been created about my problem – however, that was regarding a central ventilation system with heat recovery.
https://www.hausbau-forum.de/threads/zentrale-kwl-mit-wrg-zimmer-einzeln-regelbar.12319/page-2
We actually have a similar issue.
We are used to sleeping relatively cool at night. A room temperature of 18 degrees Celsius (64°F) in the bedrooms would be ideal for us.
We have already set our underfloor heating in the bedroom to 15 degrees Celsius (59°F). That made it bearable in winter – both of us now sleep year-round in light pajamas.
However, summer is approaching. In the last few days, I have been sweating more heavily during sleep again. This obviously affects the quality of rest.
One might think this is due to my physical condition (meaning – over the last 10 years, I steadily gained weight), but my wife has similar issues and she is definitely not overweight – in the past, I even called her “cold-blooded animal” as a nickname.
The only relief we can achieve is to fully open the window at night. Of course, this currently (spring or autumn) contradicts our efforts to save energy.
The rooms face the following directions: children’s room (south and southwest), bedroom (northwest). Before going to bed, all bedrooms (ours and the kids’) are ventilated intensively for 10-15 minutes to make falling asleep easier for everyone.
I think the combination of underfloor heating, good insulation, and the heat exchange between rooms (still happening to some extent) causes this.
Our decentralized ventilation system with heat recovery also retains the heat inside the house (which is, after all, one of its functions).
I’m slowly getting desperate. I don’t want to keep throwing open the windows and letting heating energy escape.
We’re already planning to buy extra thin duvets – similar to those used in holiday countries like Turkey, Spain, or Egypt.
Do you have any tips or ideas on what else can be done (other than getting an air conditioning unit)?

Projekt20138 May 2015 11:20We have exactly the same problem.
We never managed to warm up the old house in winter and despite having heating, we had to sleep at only 14°C (57°F). I was really looking forward to the new house with underfloor heating and a ventilation system.
Our heating is set to 15°C (59°F) and currently, we have 23°C (73°F) in the bedroom, and we can’t stop sweating. Even the thin blankets only help minimally. By now, we’re really frustrated. Even the kids complain because they’re sweating so much.

Sebastian798 May 2015 11:31That's normal—install air conditioning units; you will never regret the investment. Besides, they can also quickly provide heating...

Even the kids complain because they’re sweating so much.Normally, 23°C (73°F) in the current weather is really unusual. Besides that, our heating (in cooler northern Bavaria) hasn’t been running for days.
If your heating circuit is already closed (which it should be at 15°C (59°F)), then there is no flow in the bedroom. So how is it heating up to 23°C (73°F) from the surroundings? Strange. Or do you have large windows with direct sunlight all day?
