Hello everyone,
After a long back and forth with the building authorities, our house construction project is now about to start.
We still have an important decision to make…
Which heating system should we use?
We are planning a single-family house of about 180sqm (1938 sq ft) without a basement.
Option 1 (my personal favorite):
Water-bearing fireplace + solar thermal system + gas condensing boiler
We have our own forest, and currently, I harvest about 6 cubic meters (7.8 cubic yards) of firewood each year anyway.
Option 2 (this option is preferred by our developer):
Air-to-water heat pump from Nibe + photovoltaic system including battery (Viebrockhaus).
However, I’m concerned about the dependency on electricity on overcast days. After all, you use the most energy when the sun isn’t shining.
Regardless of the developer’s preference, what would be the best option for us?
Thanks and best regards

I think with a wood gasifier stove having 6 to 8 cubic meters of wood, heating once should definitely be enough. As I mentioned, I just checked: heating with solid fuels always requires at least two heating phases, unless the stove is only used about twice a week for a few hours. (Unfortunately, the regulations are not more precise.)
This even applies to the latest pellet heating systems.
And every 3 years, there is also a mandatory inspection of the fireplace or heating appliance.
You may agree or disagree – in modern newly built homes heated electrically, this already accounts for almost 20% of the total heating costs.

For comparison, kitchen and heating... No comment, apples and oranges and all that...Hello,
It’s absolutely true—it’s a matter of comparing apples and oranges, and both relate to costs.
For example, if someone asks about a kitchen worth 20,000 Euros, no one would suggest a kitchen for 5,000 Euros instead. Food prepared in a cheaper kitchen surely doesn’t taste worse. So why spend so much more? Reasons might include: it possibly looks nicer—subjective taste, status symbol?, enjoyment of technology... everyone surely has their own reasons.
When it comes to biomass heating, those not interested in this technology quickly focus solely on costs. But here, too, just like with kitchens, there are other reasons that might justify choosing such a system. For instance, enjoyment of heating with sun and wood, taking care of your own heating, environmental concerns... and surely many more. These reasons are just as individual as those for kitchens.
Why is it better to spend 15,000 Euros more on a kitchen than on a heating system? Why not accept such ideas?
I believe both decisions are equally valid.
On the topic of exhaust air heat pumps, I fully agree with you.

When it comes to biomass heating systems, those not interested in the technology often immediately focus on costs. But just like with kitchens, there are other reasons that might support choosing such a heating system. For example, enjoyment of heating with sun and wood, being involved in managing your own warmth, environmental considerations, and surely many others. These reasons are very individual, just like with kitchens.
Why is it considered more acceptable to spend 15,000 euros extra on a kitchen than on a heating system? Why not accept both ideas?
I think both decisions are valid.
OlliWhy does no one come up with that idea? Quite simply because for 99% of people, heating systems are a rather unemotional topic—they just need to be functional. Of course, there are enthusiasts who polish and caress their heaters every day… OK, that happens with everything.
Since the thread starter directly asked about electricity consumption and similar aspects—meaning costs seem to be the focus—the discussion naturally centers around costs. Your kitchen example doesn’t really help here.

Why not accept ideas like that as well?It’s not about not accepting it. Of course, you can do it that way. But it’s more of a personal preference.
For most people, reliability and cost-effectiveness are really important when it comes to heating.
Cooking is usually a hobby, celebrated and providing more quality of life through comfort, spending time together in the kitchen, design—especially in open-plan spaces—and so on. The heating system, on the other hand, is a box you want to see as little as possible, that should simply work, and preferably be inexpensive. Few people get excited about it (no pun intended) or enjoy it. That’s why most here reduce it to cost/benefit considerations.

why don’t you say something about this too?
