Hello!
The plan is a new build in diffusion-open timber frame construction with Isofloc (approx. 200sqm - U-value 0.16) as an extension to an existing solid building (approx. 100sqm - U-value about 0.22 or even a bit worse). It should be a central heating system that supplies both buildings (underfloor heating).
In the residential building, there should also be a wood-burning stove (I’m into that and it’s perfect for quick additional heating for us).
The general goal is to build as cheaply as possible - I can’t afford any big 'frills'. That’s why, in advance, only a gas condensing boiler possibly with solar for domestic hot water was planned (of course, it’s much cheaper to purchase than any heat pumps with controlled ventilation and solar etc. - even if that would be more reasonable in the long run).
(I don’t really like 'sweetened calculations' that only pay off after 25 years and are relatively maintenance-intensive - I probably won’t live that long :rolleyes:).
However, it has now turned out that the gas connection on the property is relatively expensive (about 35m to the main connection on the main street). Furthermore, I have already read several times that controlled ventilation (at least in this relatively airtight new build) might make sense because of moisture (mold). And if you already have that, you can also just add a heat exchanger and this and that and so on...
That’s how it is with optional extras... :mad:
So now a normal gas heating system (approx. 15,000 EUR) is facing an admittedly future-oriented heating system with controlled ventilation and all the frills (estimated at at least 35,000 EUR). For the 20,000 EUR difference, I can buy expensive gas for a long time...
Now I’m totally confused...
Is there a reasonable and affordable solution as an alternative to gas in such a case?
What do you recommend here?
Thanks!!
Best regards, Mike
