Construction costs are currently skyrocketing

Sorry, I don't understand, what do you mean?

I meant with reference to the increased fine dust pollution in indoor spaces caused by wood-burning fireplaces with room air independent fireplace inserts. That’s what your warning referred to. We don’t need to discuss that fine dust is unhealthy. We can continue this via PM if you like. heizen-mit-holz-und-hirn.de has an article on this: I’m not allowed to insert the link

[B][B]"The Federal Environment Agency and the Fraunhofer Institute give the all-clear:[/B][/B] The Federal Environment Agency investigated, on behalf of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety, in a broad study the release of fine and ultrafine particles from various indoor sources. It was proven that "with wood-burning stoves (provided of course that they are professionally installed and properly operated and maintained) no increased indoor emissions can be detected."

A comparable result was reached by a study of the Fraunhofer Institute. It states: "As long as the stove door is closed, substances are not released in significant amounts. Only when adding firewood do emissions enter the indoor air. Then the researchers were able to measure a short-term slight increase in concentration."

So the topic is closed for me, as it doesn’t belong here anyway

This relates to wood burning in general.

The Federal Environment Agency clearly advises against heating with wood.

If the homepage of a stove seller takes away your doubts, that's nice for you. However, the quotes are misleadingly shortened. The Federal Environment Agency clearly advises against heating with wood.

Interesting that you need temperatures far from 20 degrees for a cozy home. So energy saving probably won't work. We live in a single-family house from the time of the first thermal insulation regulation, where so far only the windows have been renovated, and without heating we have maintained a living room temperature of 19-20 degrees the whole time. If it's too chilly for someone, they can dress warmer or consider a blanket. The highlight in terms of pampering for me was a report about freezing children in the indoor swimming pool, because the water was too cold. It turned out it was heated to 26 degrees. We trained daily at 22 degrees 30-35 years ago... you just have to swim and not whine or argue with the coach!
