Construction costs are currently skyrocketing

You can do a lot, yes. But in the end, it also has to be economical. Sure, anyone who enjoys putting 15kWp on their roof and can afford it. By all means. I have to do some calculations though. And if I end up with a heat pump, geothermal drilling, and photovoltaics costing 40,000+x EUR at the moment... then it won't pay off in the next 20 years...

PS:
Especially since I would have to finance the 40,000 EUR at 5% or more right now, it would be a follow-up financing or even a private loan. Because I don’t have the money lying around.

By the way, electricity now costs 48 cents/kWh here (municipal utilities price).

What does gas cost? You’re quickly in the range of 25-30c/kWh. You can easily beat that with a cheap air-to-water heat pump. Even without geothermal drilling. The latter is done in single-family homes because you indulge in the luxury of a better system, not because you have amortized the additional costs in 100 years.

You have to include the investment costs, not just the pure consumption. As I said, current offer from the installer. Gas boiler out, air-to-water heat pump in, delivery period end of 2024, additional cost around 15,000 EUR. How long does a heat pump last? 15 years? In those 15 years I would have to break even compared to the condensing boiler, so that I come out at zero. I haven’t made a penny in profit yet.

I don’t see that, so it stays with gas.

PS:
And with that, we can close this chapter. I don’t need any more "heat pump is better" sermons. I’ve calculated it, it’s not worth it or barely. Especially since I don’t even have the 15,000 EUR, I would have to finance it.

Your problem is not the heat pump itself, but that your house builder wants to make a fortune on the upgrade. I also don’t know how you come up with a 15k surcharge. Unfortunately, I only have the offer for the Flair 110 electronically, but back then Town & Country wanted significantly less

Your problem is not the heat pump itself, but that your house builder wants to make a golden nose on the upgrade. I don’t know how you get to a 15k surcharge. Unfortunately, I only have the offer for the Flair 110 electronically, but back then Town & Country wanted significantly less

I told you... the installer would currently offer me the heat pump for a 15,000 EUR surcharge, bypassing the general contractor. What happened back then doesn’t interest anyone anymore today. Back then, diesel cost only 1.159 EUR per liter, yesterday I refueled for 2.359 EUR ;)

Discussions about whether things like heat pumps, photovoltaic systems, and the like are worthwhile are always tedious because everyone has to decide that for themselves and it depends on their individual circumstances. Just because it isn't worthwhile for one person doesn't mean it's the same for another. I think everyone is aware that the timing is currently difficult due to prices and many uncertainties. I also can't compare my situation from our construction nearly 7 years ago to today, but back then, for example, the main focus for me was on dependence on fossil fuels, which is why I didn't even compare the prices of gas heating to heat pumps. But when I consider that we would have first needed a gas connection in the house, a chimney, regular chimney sweep costs, and so on... then I think that at that time, the heat pump was not really more expensive than the gas heating. Especially when I see what some people pay for their heat pump today, back then those were still the costs for the entire heating & sanitary trade with all the trimmings. And the photovoltaic system from 2 years ago was also the best investment in the whole house. For us, the investment will have paid off after about 5 years and after that, we are saving. But just because that's the case for us, it doesn't have to be the same for everyone. Everyone should be able to best assess their own situation whether such purchases are worthwhile or not.
