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’d also like to put the wood gasifier forward. You use about 2 cubic meters more wood, and your house stays warm if it’s properly insulated.

It takes work, but you’d have that with a wood stove as well. On the plus side, you save on the gas heating.

Best regards

If there is gas supply in the street, go for a gas heating system. If not, choose an air-to-water heat pump.
And if possible, avoid installing anything on the roof.
Just the annual cost for the chimney sweep would cover two months of heating your place with a gas system.

Unless you want to invest a lot more money for significantly more effort. Then four! (wood, gas, solar, battery) expensive, complex systems are exactly what you need.

PS: You depend on electricity with every heating system.

Just the annual chimney sweep costs alone could heat your place for two months.

For 6 cubic meters of firewood, one chimney sweep per year costs 26€ (about $28).
I just doubt that.

Well – we have two of those here. And every few years there's also a "heating system inspection." I end up paying just under 100 euros per year. And that’s the cheaper one!

Just checked: unfortunately, this is exactly what is required by law. So, it won’t get any cheaper than that.

Our chimney sweep said he would come as needed. We burn a total of about 10 cords of firewood per year with two wood stoves. So, he comes twice.
I think with a wood gasifier stove using 6 to 8 cords, once a year would definitely be enough.

Well, it always depends on the specific local conditions, as is often the case.
