Suitable heating system for new construction - how to choose?

OK, but that really gives me split ends – renewable raw materials are being burned up just to see a nice flicker, and the heat is blown outside because the living room might get too warm,... Late Roman decadence is probably the keyword here.

That sounds as if you haven't yet looked more closely at wood stoves, their different constructions, and their ecological balance. Compare a masonry stove with a heat pump using the usual electricity mix or "green electricity" from a biogas plant. Oh, surprise! Today we have so much scientific knowledge and understanding of connections that it’s hardly possible to do anything consistently right anymore. However, we also have enough insights into connections to know what is consistently wrong in any case. Moreover, we are aware of gaps in knowledge and continue to research. In my view, it is enough to consciously behave as harmlessly as possible. Demanding the utmost consistency from one another is societal poison, which leads to group formation and mutual ostracism. Some are no longer allowed to travel, others are no longer allowed to commute to work, some are no longer allowed to have a fireplace, others are no longer allowed to eat meat... Everyone forbids everyone else what they themselves consider unimportant or can easily do without. Promoting sustainable action—wherever and whenever people want and can—is, however, sensible and advances our society in discourse (which I find very lacking here; the Dutch, for example, are miles ahead of us). For this, proven personal and political will to refrain from harmful actions is necessary.

In my view, it is enough to consciously behave as little harmful as possible. Demanding the utmost consistency from each other is societal poison that leads to group formation and mutual ostracism. Some must no longer travel, others must no longer commute to work, some must no longer have a fireplace fire, the next must no longer eat meat... Everyone forbids everyone what they themselves do not consider important or can easily do without. Advocating sustainable action—each where they want and can—is, however, sensible and advances our society in discourse (which I greatly miss here; for example, the Dutch are miles ahead of us). This requires the personal and political will to refrain from proven harmful actions.

I have dealt with it extensively, thank you. We are getting a wood heating system because we have our own forest, but we have also looked at all other alternatives. When I read that good firewood is only wasted for the appearance and the heat is disposed of as waste, it puts me in a bad mood as a forest owner. Then it’s better to install an ethanol fireplace. It flickers too.

I am still in favor of an 80-inch Netflix fireplace in 4k. When it comes to the appearance....

also saves you from having to dispose of the ashes and the spiders that come into the living room with the firewood. :)

Google "forest". It says among other things that it can grow back quite quickly depending on the type. Maybe that will improve your mood.

Well, I actually like spiders. They catch the mosquitoes - I don’t like those.
