Fireplace or stove in the Energy Saving Ordinance 2016 for new buildings

Hello Pädda,

in the end, it will be the large pane that overheats the room, namely through the direct radiant heat, which you simply cannot control that well.

With the current heating concept, I would also dispense with a water-based fireplace.

We have a 4 KW stove from Skantherm and are completely thrilled. (Very) small combustion chamber, but quite a large pane due to the elliptical shape.
For us, what ypg said applies

Hello Pädda,

in the end, it will be the large glass pane that overheats the room, namely through the direct radiant heat, which you simply can’t control that well.

With the current heating concept, I would also forgo a water-heated stove.

We also looked at the 4.3 kW stove from Skantherm. The same model is also available with 6 kW and a larger glass pane, and my wife would like to have that one. Unfortunately, the glass pane of the smaller brother with 4.3 kW is too small for her...

Why do you think a water-heated stove doesn’t fit into the concept? I think that for the 53m2 installation room of the stove, max. a stove with 4 kW would be perfect. Anything above that, in my view, would only overheat the room.

My only question is whether 2.8 kW with a water-heated stove is not too little for the large room. Do you have experience regarding how many kW one should at least take for around 53m2 in a new building? Unfortunately, I only ever read about overheating starting from xx kW but nothing about the kW number possibly being too small...

You will ALWAYS overheat your room with this because the room already constantly has its normal temperature. The heat from the stove is always added. If you overestimate this, then you have to do without blazing fire.

Well, it will probably take 1-2 kW to maintain the room at the starting temperature. Depending on the outside temperature, etc. With a "Speicherofen," such lower heating capacities are more feasible. Operating a stove (as a supplement to the heating system) is generally hardly reasonable; this applies all the more to a fireplace. A water-bearing fireplace also has too much output for the installation room, and the installation is relatively expensive. In this context, it would first be necessary to consider how much heat your Speicher can absorb and at what temperature level it operates.

From my point of view, a combination of slow floor heating and an ad hoc operated stove/fireplace cannot truly work efficiently. Basically, efficient heating requires low flow temperatures. This, in turn, only works with many open heating circuits and proper hydraulic balancing. An external heat generator can only mess up the system. Or you consciously accept too high flow temperatures and regulate with the thermostats. It just doesn’t fit so well with modern houses anymore.. My neighbors also have the problem that they suck in their own fireplace exhaust gases with the [Kontrollierte-Wohnraumlüftung]....
