Luxury: yes, cool Necessity: no Economic efficiency: catastrophic

I see it a bit more differentiated: Luxury: yes, cool (as is the case with some controlled residential ventilation solutions, by the way) Necessity: It addresses an urgent need for us that used to be life-impairing in winter. Not universally applicable Economic: As always, a matter of calculation. As the only heating system in the house in a pragmatic version, a basic stove is economically absolutely competitive. Ours is probably not economically optimized, but at the same time a sustainable piece of furniture.

I started a fireplace discussion there. ;)

Some supporters have responded, but brought few factual arguments that make a fireplace appear ecologically or economically sensible.
Rather statements that with even more money and even more mass the overheating can be somewhat mitigated.
Mass does not change the amount of energy introduced (about 4 kWh per kg of wood), but only the duration over which it is distributed.

Therefore my basic statement, a nice but pointless acquisition. :)

Firewood is not much cheaper than, for example, gas, unless you have cheap sources.

Gas in KFW40+ how do you manage that?

I have started a fireplace discussion here. ;)

Some supporters have come forward, but they have brought few factual arguments that make a fireplace appear ecologically or economically sensible.
Rather statements that with even more money and even more mass you can somewhat mitigate the overheating.
Mass doesn’t change the amount of energy input (approx. 4kWh per kg of wood), only the duration over which it is distributed.

Hence my basic statement, a nice but pointless purchase. :)

Gas at KFW40+ how do you manage that?

haha something like a vacation. nice but pointless?

much of what you could buy with money would then be nice, but pointless.
I will definitely remember this sentence :D
PS: I wouldn’t install a stove in an investment property either.

Yes, exactly! If you do it wrong, it can even become unpleasant with a fireplace in kfw40.

Thank you for the answers, I had unfortunately already suspected that. Although a fireplace was planned from the start at our place (construction begins in autumn), the structural analysis is already complete and we unfortunately did not discuss special requirements due to higher weight with the architect...

Could you still ask about it there or have you decided on an alternative?

Mass does not change the amount of energy supplied (approx. 4kWh per KG of wood), but only the duration over which it is distributed.

That is precisely the point of the mass - flattening the curve of heat output. That is why you can get by longer with the same amount of wood to sit comfortably warm. Somehow that sounds like efficiency, doesn't it?

If you do it wrong, it can even become unpleasant with a fireplace in kfw40.

Absolutely right, with poor planning and execution, you bring the summer heat buildup problems right into the winter. A thoughtful design tailored to the rooms and the house is unavoidable, just like with any other heating system. However, turning off your thinking during planning is not a problem of the heating system.
