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

PäddaHello.
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.

Knallkörper20 Jan 2018 21:55I can only recommend a stove with high thermal mass for this. You won’t want to use a steel box with 5 kW, speaking from experience. We have one with 7 kW and a relatively large heat storage mass. It takes 3 hours to reach full heating output (then we let it burn out slowly), and it is cold 8 hours after heating ends.
I have a different opinion than Knallkörper.
It’s no use for someone who wants a fireplace for cozy warmth in the evening or on weekends if they only feel the heat three hours after lighting it, and that heat then spreads through the house at night when everyone is asleep. Instead, when coming home from a chilly walk in the late afternoon, you want to light the fireplace and warm yourself directly at the heat source—the stove.
At night, it can cool down again without any problem.
The same applies to the warmth: in our case, it’s not extreme because we have an open plan upstairs, so the heat distributes well. If it does get too warm, we just open the terrace door for 2-3 minutes and that resolves it.
I don’t know how it would be with soapstone, but we deliberately decided against a heat storage unit so the warmth can be controlled; meaning when the stove is off, the temperature returns to a normal level where you can be active again.
So: fireplace on -> radiant heat, nice and warm. If it gets too warm, just open the door briefly. All good. The next morning, you have your normal daytime temperature for activities again.
We have an air-independent Olsberg stove Palena with a nominal output of about 5 kW for approximately 55sqm (about 592 sq ft).

Our stove is also intended as a "backup" for the regular heating system. If needed, or in case of a public supply failure, we could use it to heat almost free of charge.
I share a similar view to ypg. However, we have a small, freestanding stove WITH soapstone.
Choose a small freestanding stove (whether with or without soapstone is a matter of taste – also visually) with a nominal output between 3 and 7 kW (depending on the air intake you set), and you won’t have any overheating issues.

Of course, we would prefer to keep the windows despite having a stove. Since we are still in the planning phase, all options are still open. My wife also wants a large glass panel on the stove. Yesterday, we visited a stove retailer again. The smallest stove has a heat output of 4.4 kW. I wouldn’t have any problems with that. However, my wife prefers one with 6 kW because of the larger glass and the nice view.
What do you think about a water-heated fireplace like this? We saw one with 2.8 kW heat output to the room and 7.2 kW to the buffer tank. We liked that. Since we would also have a gas heating system with solar panels, the buffer tank would already be there anyway. I assume that the hot water produced by both the stove and the solar system can be fed into a common buffer tank, or am I mistaken?
