Suitable heating system for new construction - how to choose?

If you have to regulate underfloor heating, you have made mistakes in the design or the thermal balancing is missing or the shading concept is incorrect. Otherwise, you turn it on once a year and off once a year. And this even happens automatically. With the highest comfort.

You keep repeating that one shouldn’t build at all. Of course building is an environmental burden and a single-family house more so than an apartment block. But for many, this renunciation is out of the question. Therefore, it’s about choosing the "right energy concept" within these desires. So one that harms the environment the least without significant loss of comfort.

Why is renunciation out of the question? Just because you want your own land? There are few concrete (I would say no) environmentally conscious reasons why one decides to build a house.

Then I’ll give you another example. Venetian blinds/roller shutters. People build bright open spaces only to darken them in summer (which arrives surprisingly every year). Many materials are wasted and electricity is consumed for this... Or they immediately install an air conditioner, which does not consume little electricity. The excuse that we have a photovoltaic system doesn’t hold either. That doesn’t come from thin air either.

I could give many other examples that others have done who now complain about the fireplace. Examples like insulation, plastic flooring (vinyl), 80-inch instead of 55-inch TVs, lots of sealed surfaces, little natural garden, etc.

One shouldn’t pick out the small things to criticize but maybe consider the big picture.

Has anyone ever read statistics about what is better: heating with a fireplace and constantly burning wood or heating with a brine-water heat pump including photovoltaic support and using the fireplace as a decorative fire 10-20 times a year?

If you have to control a underfloor heating system, you made mistakes in the design or the hydraulic balancing is missing or the shading concept is not right. Otherwise, you turn it on once a year and off once a year. And that even happens automatically. With the highest comfort.

Correct. With us, each room is set individually to 19-21 degrees. There is also a hydraulic balancing that the construction company performs. So you have underfloor heating and also heat with a fireplace. You ENVIRONMENTAL KILLERS!!!

And why did you build a house then? It's totally ecologically wrong if you care so much about the environment. When you consider a) space usage, b) soil sealing (concrete slab) and c) material usage... better to live in a modern apartment building.
How was it with the glass house and the stones?

We didn't build new, we are renovating a house over 200 years old. With ecological building materials where possible, we recycle where possible, and we use regional building materials and craftsmanship where possible.
Shocking, I know.

we are not building new, we are renovating a house over 200 years old. With ecological building materials where possible, we recycle where possible, and we use regional building materials and craftsmanship services where possible. Shocking, I know.

Nevertheless, it would be more ecological to build an apartment block for several families there than for one family. You can sugarcoat everything. But single-family houses are simply never as ecological as apartment blocks with the same construction method. Apart from the fact that the old house will not be as energy efficient as a new building.

As already said. Glass house and stones...

Despite everything, it would be more ecologically sensible to build an apartment block for several parties there, rather than for a single family. You can sugarcoat everything. But single-family houses are always ecologically less sensible than apartment blocks with the same construction method. Apart from the fact that the old house will not be as energy-efficient as a new building.

As already said. Greenhouse and stones...

No, apples and oranges. But keep convincing yourself that your stove-disguised outdoor space heater is great. :D
