Geothermal heat pump or gas boiler - experiences?

@WilderSueden : Scientists see it differently. Take a look at the study on it.

Not wanting to take over the thread with the topic now: - clear attribution and quantification are impossible for such complex processes - there are enough scientists who call the problem by its name, e.g. Roggenkamp: "In the Ahr valley, as in many other places throughout Germany, construction took place in the natural floodplains of the rivers." (FAZ from August 5) - many scientists explicitly shy away from taking the side that this is not a climate change problem. The reason is waves of outrage and the danger of being appropriated by various groups with whom a serious scientist wants to have little to do. Those who blame climate change do not have these problems - a flood of 1804 is not attributable to "man-made climate change" but rather a natural extreme event. Humanity is very good at systematically underestimating extreme events. A good read on the topic is The Black Swan by Nassim Taleb - soil sealing and climate change certainly contribute their part, but focusing only on these points is far too narrow. Precisely because even with much less sealing and without climate change, more extreme events have already occurred

The ecological aspect of every energy consumption seems so obvious to me that I actually don't need a scientist for it. But science also says that human influence on the climate is clear. We humans are warming the Earth's atmosphere. That there may have been similar floods in the Ahr Valley before measurable human influence does not change the fact that the probability of storms everywhere in the world - including in the Ahr Valley - has increased and - also for this reason - every saving of energy - as well as a more efficient usage - is to be welcomed. I find the seemingly differentiated consideration of the cause of the Ahr Valley flood completely "off."

Even though there are arguments against heat pumps, an interesting current article:

Google: EU Commission wants to classify gas and nuclear power as green

The question is what this will lead to?

If you want to do that then do it! And don't let anyone talk you out of it. With the plot size, everything is open to you.

Okay thanks that is also the best approach.

The question is what this will lead to?

One wonders if this will happen, but it would be the logical next step, since the options have long since run out.
