ᐅ No underfloor heating in the bedroom?

We have an underfloor heating system from 2001, which may have been installed suboptimally. It is also installed in the bedrooms and children's rooms.
I also get the impression that it’s not suitable for sleeping with the windows open.
Radiant heat is pleasant. The body feels warm while the air stays fresh and cooler. Consider looking into a stove or infrared heater; the latter is quite affordable.

I also find the argument about it being too warm really outdated.
Do you never go on vacation to warm places? Can none of you sleep there? Do people in Africa suffer from insomnia?
It’s all just a matter of getting used to it.
You just use a very thin blanket or only a sheet and a short or no pajamas, and it’s fine again.

We actually feel it gets colder in the bedroom when the door stays closed all day. But since the door is open at night anyway because of the child, the difference quickly disappears again.

Why does the door have to be left open because of the child?

Guess what happens in today’s airtight houses if you don’t have heating in the bedroom... right, you get mold.

It’s not just about ventilation; heating is also important. In our apartment (external thermal insulation composite system - ETICS) during the first month when it was below freezing, we didn’t heat the bedroom. The consequence came 1.5 months later: mold spots in the upper corner and all along the window side.

Well, rooms usually don’t have airtight doors. The heat still circulates within the thermal envelope. The mold spots rather suggest installation errors with the ETICS.

We have underfloor heating in the children’s room and the bedroom—low in the children’s room and very minimal flow in the bedroom.

The floor is not cold, and even with the window open, the air is pleasantly cool these days.

Haha, this question can almost only come from someone who doesn't have kids ^^
Well, it’s because the child might wake up and cry, and then you can hear it sooner.
Or because the child wakes up and wants to come into the bedroom but isn’t able to open the door by themselves yet.
There are definitely reasons for that 😉

With a radiator, you just set the thermostat to one and that’s fine. If you want it a bit warmer, set it to two, and it heats up quickly. So, for bedrooms, I actually prefer radiators. Unfortunately, nobody advised us that way.

With underfloor heating, you can also turn the room temperature completely down. Of course, it doesn’t warm up instantly when you want, but that’s not necessary in the bedroom either. You mentioned that yourself. Cooling down individual rooms in the house is also counterproductive.

Using a radiator in a heating system designed for underfloor heating creates additional problems. Either the radiator has to be very large to operate with the same supply temperatures, or a second heating circuit must be added to the system with the usual higher temperatures for radiators. This means more hydraulics in the heating system room, more controls, and naturally more losses just because the heating water has to be heated to twice the usual temperature for underfloor heating.

In such cases—like for people who sleep with windows open—I don’t think underfloor heating is ideal. It just heats unnecessarily.

Simply turn it down to frost protection mode. Problem solved.

We can regulate the temperature of the underfloor heating in individual rooms. So it’s no problem to keep the bedroom cooler or even switch it off completely for open-window sleepers.

Exactly... if you want ERR and it works, then it’s possible.

We can do that too... but somehow it’s like it handles 21°C (70°F) fine, but doesn’t like 15°C (59°F), it’s always too warm.

Then I would call the plumber/heating technician to take another look.

Brrrrr 15°C (59°F)
