Conversion of gas boiler to heat pump

Does anyone have experience with the Panasonic Geisha air-water heat pump? This one is comparatively inexpensive. How is the hot water preparation implemented? Are there square hot water storage tanks? The round ones don't look very elegant.

Our plumber from the well-known area raves about them, they are supposed to be top devices at a good price. Unfortunately, the conditions for dealers are apparently not great, which is why he usually installs wolff (simply better margin). I quote his statement

What a tip :rolleyes: You don't mess around with water or electricity in the house as a layman!

The tip is that you order the devices abroad. There are somewhat better conditions there. But everyone has to decide for themselves. In the future, we will have to do a lot more ourselves. At least then I know what I have done.

and who installs them then and provides a warranty? You won't find a (reputable) craftsman...

One has to swallow a bitter pill. I will assemble it completely myself, of course with the help of a systems engineer.

You have to swallow a toad. I will build it completely myself, of course with the help of a plant constructor.

Then in the worst case it is installed incorrectly or broken after a year, and without guarantees a lot is saved.

Then, in the worst case, it is installed incorrectly or broken after a year, so a lot is saved without guarantees.

But that is not what this article is about. Everyone can decide that for themselves. Over the past years/decades, I have always done well with it. You also don’t get any dumber from such a project. You definitely see how many so-called experts and professional companies are on the market.
