Air heat pump and electricity consumption

Although, one had water in the chimney/flue (?), and somehow the floors and walls in the basement became damp and need to be dried. It’s not the gas condensing boiler itself causing the problems, I guess this can happen with all systems with chimneys/flues (?) They probably should have had the chimney inspected regularly, which they didn’t even know.

I want reliable technology, so no cheap crap, but on the other hand, I don’t want to overpay for technology just because of a name.

To put it in terms of cars: for me, the Skoda Octavia, VW Passat, and Audi A4 are roughly equivalent in terms of technology, safety, consumption, and space. My choice would be the Passat or the Octavia because I don’t see why I should pay 2000 EUR per Audi ring on top.

What I want, probably everyone wants who has a limited budget: a good price/performance ratio. That means putting the size of the living area in relation to the costs, as well as the heating technology in relation to the costs. This applies to both the acquisition and operating costs. The additional costs should pay off within the first 5-10 years, then I’m happy to invest more initially. But if it takes 20 or 30 years, it’s probably more for enthusiasts and idealists. By then, other technologies will be relevant, and that before what is currently installed has even roughly amortized. For example, my father has had very good experiences with Vaillant gas boilers and hadn’t even considered other types of heating. Now he is dealing with heat pumps and increasingly with ventilation systems and seems to find it at least interesting and worth discussing.

By now, a ventilation system seems more important to me than the decision between air-water heat pump/gas, but now it also comes in that I much prefer underfloor heating over radiators and whether that can be sensibly combined. Domestic hot water heating should be supported by solar energy and a stove for the transitional period and cozy warmth is a must for us anyway.

I need to sort out all my thoughts and maybe describe the ideas combined. Complex topic... and I don’t want to talk myself into trouble. It definitely doesn’t have to be variant x or y at all costs, because one is fundamentally great and the other fundamentally nonsense. The combination of acquisition costs and everyday operating costs should be the cheapest for us and, of course, reliable as well.

Best regards

That means setting the size of the living area in relation to the costs, as well as the heating technology in relation to the costs. Here, both acquisition and operating costs are considered. The additional costs should pay off within the first 5-10 years; then I am gladly willing to invest more upfront.
