Heat pumps have been in use for 100 years, and in the private sector for almost 50 years. So a mature basic technology that has, of course, become enormously popular in the last 10-20 years.

I tend to lean more towards 10, before that there simply wasn’t enough for widespread studies

That is indeed true in this respect: the gas boiler is simply fully matured compared to the heat pump, which has only been popular for a few years.

The recommended option is precisely the one where you can make good profits and have experience.

Why should anyone offer a heat pump monoblock for €2,500 when they can offer gas or a more expensive heat pump for €5,000–15,000?
I am installing one myself in the new building because several friends of ours have already had very good experiences with the Geisha.

And at the low price, I can buy another Geisha in 10 years if it breaks and still come out ahead.

so you will then also install the newer "WH-MDC05H3E5"? Because I am currently looking at the data of this heat pump. "Operating range down to -20°C". What actually happens if it gets colder? Does that mean that the electric heater only switches on from -20°C and you then heat 1:1 with electricity, or how?

Yes, I will also install this one. The electric heater switches on from the bivalence point. That depends on the load depending on the mode of operation. Rather in the range of -5° to -9°. The heat pump should generally not be used below -20°. But that is rather unlikely in our case.
