Hello. A question for the experts and experienced home builders:
We are planning to build soon and already own a building plot. A natural gas line is available on the property. Since gas is quite expensive and alternatives are often considered... Is it sensible to combine a gas heating system with solar thermal for domestic hot water preparation? Or would it be better, considering current prices, to disregard gas heating and switch completely to, for example, a pellet heating system? It will be a single-family house. The exact heating demand is not yet known.
I would appreciate some basic information to understand the options better... I will consult professionals later but want to gather information through forums first... Many thanks in advance.

Hello €uro, “smart” as always... Please forgive a certain bluntness; perhaps it’s because I’m not only a desk worker but also a hands-on practitioner. Bauexperte schrieb:
...I hope I remember. To help pass the time, I searched the internet for “builder specifications” related to solar houses. We probably shouldn’t discuss how advertising is designed and promoted in detail ;-) Bauexperte schrieb:

Seriously though: It’s interesting to follow your discussions, but in the end, it just confuses and unsettles me personally (and I’m probably not the only one). Reading different opinions is good, but with you, it all feels so "insider talk" that an average reader can’t understand anything anymore. Just my 2 cents...

I always find what the two contribute very interesting.
However, without an accurately calculated heat demand, it is always difficult. If you want to do it right, invest the money and hire an independent HVAC engineer. Of course, this is only possible once the complete building design is finalized.
As an amateur tip: what’s the point of an oversized heating system in a well-insulated house if very little heat is actually lost? The efficiency then drops significantly because the system has to heat up less often. For heat pump systems, this results in a low coefficient of performance.
Best regards
