Hello,
a similar thread has already been created about my problem – however, that was regarding a central ventilation system with heat recovery.

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)?

Although the question remains, what exactly can the system installer change here? After all, they can’t prevent heat exchange between the rooms.
At this point, I don’t see any solution other than purchasing even thinner ceiling panels as mentioned.
Who would have thought I’d be dealing with a problem like this?
Up until now, it was always about efficient heating, proper insulation to keep the warm air inside, ventilation that doesn’t blow out the heating energy—in other words, living as energy-saving (or rather non-wasteful) as possible.
And now exactly this issue is causing us problems 😕?

Sebastian7924 Apr 2015 14:49Unfortunately, this is normal with today's insulation standards – which is why we have air conditioning in the bedrooms and living room...
A common issue in newly built, insulated homes. Temperature differences greater than about 3 degrees Celsius (5°F) are hardly achievable.
In the bedroom, we have reduced the heating circuit to a minimum flow rate – yet in winter it still reaches around 19 degrees Celsius (66°F).
In spring and autumn, the window is often tilted open. In summer, unless there are extremely hot and humid nights, we use the mechanical ventilation system to draw in cooler night air (none of us have allergies).

EveundGerd6 May 2015 21:05Oh, that will definitely be a problem for us too. 😕 We don’t need it very warm, and in the bedrooms, we all like it cool.
In two weeks, we will have the briefing on our heating system. I will ask the technician about the flow temperature. Hopefully, we’ll be lucky and can avoid the problem from the start.
