You can read here enough about heat pumps and also gas, especially regarding function, problems, advantages/disadvantages, etc. If you put the topic of "fossil fuels" in the foreground this way and share the opinion that gas is the "wrong" way, then a decision has surely already been made. At the beginning, you wrote about "standard" for your house construction, and a gas heating system is currently a good standard, also inexpensive and reliable.

3-4 years ago in Norway I was completely amazed by the market share and the normality of electric vehicles there. Before these actually only a few months ago :D it was still a complete foreign or only ridiculed and provocative word here at our place at that time. Today, even here in the forum, this is practically considered standard... sometimes things change in people’s minds that fast. Therefore, I wouldn't be so sure whether my current heating choice will still fit equally well in 10-15 years, probably not, if in the last 3 years a previously unthinkable revolution has taken place in the market of the German hobbyhorse "car". I consider the so-called standards rather fluid; it is like buying a car, when today you are sold the greatest car, which is then presented by the same seller as a problem case during trade-in tomorrow. I think you already have preferences and that is good; nevertheless, there are always other options one can find for oneself if one looks for them. Flow temperature is eventually the dependence on a willing, available, adequately trained, and affordable craftsman the problem of our society... who knows. Topic independence: making a piece of forest and wood yourself! Currently many decisions are often made because of subsidies, which ultimately says nothing about their sense for the individual or his/her heating system.

Then definitely don't buy a heat pump :D

Then definitely a heat pump. Maybe, for example, a trench collector could work for you.

So , now you have the mess, both are right and can justify their experience/opinion; in addition, there are others...... As a thought-provoking suggestion, I would like to recommend THIS to you again: https://www.hausbau-forum.de/threads/bestandshaus-heizung-modernisierung.39030/#post-492597

Why? You have to get involved with the subject matter every now and then, don’t you?

First of all, you will probably have to set and adjust everything yourself, because heating installers almost always do a standard IBN. And then the heat pump will make you so poor. Depending on the system configuration, that’s not easy; I have invested many hours and weeks in it.

In addition, the systems still tend to have defects, you can read about it by googling. Much more frequent defects than with gas boilers. Of course, you can also be lucky or just go for gas right away.

And a purely personal opinion: with a heat pump, I see a wood stove as mandatory. So you can heat with it in case of defects or during the transition period.

But I admit that the current trend is strongly towards photovoltaics and heat pumps, which also has its appeal. I also believe that a conversion in 20 years will be very easy. Ideally even with better, more efficient systems and government subsidies. You can also use photovoltaics very well with it.

For this reason, gas is currently unbeatable.
