Wood-burning stove in new construction - What to pay attention to?

Hello everyone,

we have built a KFW55 house and are now facing the choice of the wood-burning stove. Underfloor heating using a heat pump and ring trench collector is available, no ERR. A proper heat load calculation is not available, except the one from the underfloor heating manufacturer. But you can forget that because it was made on a general basis. How all this will play out in practice is still uncertain; we are only moving in 2 weeks. Estimates suggest about 32° flow temperature.

The location is the open kitchen/living room area with 55 sqm. Central controlled residential ventilation is available. The goal is to bridge the transitional period and invoke the "romantic factor." No water-bearing stove desired, no masonry heater.

I was thinking of a 5KW model here, or is that already too much to overheat the room? Do I have to consider parameters like efficiency and similar things with these conditions, or does it not matter anyway and I can just get a DIY store stove?

Buying based on appearance is, in my opinion, completely sufficient. For romance, you don't need more. It only gets really too warm when you have a lot of storage mass in your stove.

In new construction, there is only one thing to consider: the stove needs a lot of thermal mass! You can't achieve that with hardware store devices.

Therefore, have it built with masonry, otherwise you end up with a sauna and that is unpleasant.

Masonry costs start at 6,000 and go up to 20,000. We paid 10.

A lot of thermal mass means that a lot of heat is absorbed and then released again. That’s what I do when I want to heat.
If I just want to have a nice fire for a moment and don’t want a sauna, I avoid that as much as possible. In that case, a hardware store stove from €1,000 is sufficient. And if someone wants to see a lot of fire, they take a stove with a large combustion chamber and a big glass pane. Those can also be 12 kW – based on my own experience, that works very well and doesn’t heat the room too much.

So I have an 8.7kw room-air-independent stove with an open room concept (from the showroom to the basement, upper floor and hallway without doors, so everything is open) and a living space of 55 sqm. It does not overheat at all. The maximum temperature I reached after 4-5 hours in the living room was 26.x degrees. My suspicion is that this is due to the room-air-independent concept, because the stove is completely sealed and does not release hot air from any gaps into the living room. I basically only have radiant heat through the glass. Even that strange grill on top is closed.

do you have a fireplace with air supply?
do you have a pressure monitor installed?
have you spoken to your chimney sweep?

we have a justus reno R, that's basically the most expensive thing you can get at the hardware store and from oranjer. when we heat properly, we get up to 26 degrees in the basement and about 23 in the upper floor, we have never had more than that. the starting temperature is 20 degrees.

talk to your chimney sweep.
