ᐅ Fireplace or Stove in the 2016 Energy Saving Regulation for New Buildings

Hello.
We are currently planning a stove or fireplace. We have already successfully dealt with the "negative pressure problem." What really bothers us, however, is that for a new build, we couldn’t find any fireplaces or stoves with such a low kW rating that the room wouldn’t overheat.
Soapstone stoves usually have a correspondingly low kW rating, but my wife doesn’t like their appearance.
Fireplaces generally start at 5 kW, which will likely overheat the room.
Do you have any ideas if there might be a suitable fireplace or stove for us without turning the room into a sauna?
The house will meet the minimum requirements of the 2016 energy saving ordinance (EnEV).
There will be a ventilation system with heat recovery.
Otherwise, gas heating combined with solar and underfloor heating.
The installation room (living/dining/open kitchen) is 53 m2 (570 ft2) in size.
My current thought is as follows: Based on a rough calculation of the appropriate kW rating, I would come to a maximum of 3.7 kW (0.7 for new builds x 53 m2 (570 ft2)) for the stove or fireplace. It might be possible to install a water-heated stove or fireplace with a total kW output of about 10, where 6 kW flow into a buffer tank and only 4 kW heat the room. Or am I making a mistake in my thinking here?
We will put aside the fact that this would be significantly more expensive due to additional piping etc., as well as the payback period for such a water-heated stove/fireplace. My main concern is finding a way to avoid turning the room into a sauna or having to keep all windows open all the time while heating with a stove or fireplace.

Hello Pädda,
In the end, it will be the large glass panel that overheats the room, due to the direct radiant heat, which you simply cannot control that well.
With the current heating concept, I would also avoid a water-based fireplace.
We have a 4 kW stove from Skantherm and are completely satisfied. It has a (very) small combustion chamber, but because of the elliptical shape, it has a fairly large glass panel.
For us, what ypg said applies.

We have a 4 kW stove from Skantherm and are absolutely thrilled with it. It has a (very) small combustion chamber, but thanks to the elliptical shape, the glass panel is quite large.
For us, what ypg said applies We also looked at the 4.3 kW stove from Skantherm. The same model is also available with 6 kW and a larger glass panel, which my wife would prefer. Unfortunately, the glass on the smaller 4.3 kW model is too small for her...Why do you think a water-based stove doesn’t fit into the concept? Considering the stove’s intended room size of 53 m² (570 ft²), a stove with a maximum of 4 kW would be perfect in my view. Anything above that would just overheat the space.
I’m just wondering if 2.8 kW in a water-based stove might be too low for such a large room. Do you have any experience regarding the minimum kW rating for around 53 m² (570 ft²) in a new build? I often only read about overheating above certain kW levels, but nothing about when the kW rating might be too low…

Such lower heating outputs are more achievable with a "storage stove." Generally, operating a stove (as a supplement to the main heating system) is rarely practical, and this applies even more so to a fireplace. A water-based fireplace also produces too much power for the room it’s installed in, and its installation costs are relatively high. In this context, the first thing to consider is how much heat your storage unit can absorb and at what temperature level it operates.
In my view, a combination of a slow-reacting underfloor heating system and a wood stove or fireplace operated on demand cannot work efficiently. Essentially, efficient heating requires low supply temperatures. This, in turn, is only possible with multiple open heating circuits and a precise hydraulic balancing. An external heat source can only disrupt the system. Alternatively, you deliberately accept higher supply temperatures and regulate with the thermostats.
This simply doesn’t fit well with modern houses anymore.
My neighbors also have the problem that their controlled mechanical ventilation system ends up drawing in the stove’s own exhaust gases...
