How many degrees of heat loss per night is "normal"?

Hello,

I don’t know which law states that you have to install a heating system? Accordingly, I could also move in with just a wood stove if I wanted to. Which pipes are supposed to burst? We have 17 degrees in the house at the lowest point. Nothing will burst

Considering that you are a layman, you sound quite defiant!

Pipes probably won’t burst, but your Swedish slab can very well become a problem itself since the house is only heated temporarily. I always wonder why builders choose this type of floor slab; especially regarding sound transmission it has disadvantages, and it’s not cheaper either.

The construction was dry from the start.

How do you know that for sure?

Rhenish regards

It would be different if you really heated properly, then the materials would also warm up and they would retain the heat longer according to their material properties.

Not much would change. The material wood simply has a low heat capacity, so it always stores relatively little in comparison. However, that does not mean it is automatically uneconomical.

Hi construction expert: OK I didn't mean to be insubordinate. But the annoying thing is that in forums basically you are first confronted with accusations, criticism, and badmouthing because everyone always thinks they know everything better, can do everything better, and has the best stuff. And especially with things like these. Show me where it says that it is legally not allowed to move into a house without heating (especially since the stove is in a way even part of the heating system). I am a layperson and happy to be enlightened.

I am not going to start a discussion about the Swedish slab now

But that the construction was dry? - Why not? The slab is made of concrete. And it had plenty of time to dry.

You should read my posts more carefully and understand them correctly

Your house is not designed just for your wood stove, so you shouldn’t be surprised that it doesn’t get warm.

And of course, it is naive and irresponsible to accept the house without heating. It would be irresponsible on our part to leave this fact uncommented so that others don’t think it’s normal or acceptable.

Regards

Don't worry about it.
Even though 50% humidity in the house is a bit high for this time of year, with a solid wood house and no screed, as long as you heat and ventilate daily, there is nothing to worry about.
Your heating system for this area and building type will not be much more powerful than your stove. I’d guess about 9kW (+/- hot water preparation).
The difference is that in the sizing of a heating system, a heating interruption of about 7h/day is calculated (not to be confused with full load hours). But for you, currently a 6kW stove is only on for about 6 hours.
A stove is a supplement to a contemporary heating system, not a full replacement.

I find 4 degrees heat loss for a house that is currently only intermittently heated with a wood stove in one room to be little. The temperature equalization that takes place from the unheated rooms to the heated room after heating is stopped will make quite a difference. I also don’t understand how anyone could find that a lot. If I could heat the whole house from one room with a normal wood stove (without any useful storage capabilities or the like) in a new building (with whatever thermal insulation at all), why would anyone still invest in gas, oil, or other expensive heating systems? Then you could simply put a wood stove in the place for 2000€ and that’s it for heating... sure...
