Hello,
I have a well-insulated KFW40 house from 2014 with underfloor heating and 170m² (1830 ft²) using a Weishaupt gas boiler WTC 15 (heating + hot water).
The gas boiler has two heating circuits. One for the house and the other for the garage. The garage is connected via a district heating pipeline (about 8m (26 ft) from the house). The garage should only be kept frost-free.
My annual gas consumption (heating + hot water) was about 9700 kWh.
I believe my house is well suited for a heat pump. Unfortunately, I wasn’t that knowledgeable back then.
Now my questions.
1. Which type of heat pump would you recommend (ground source or air source)?
2. Where can I install the heat pump? A) Inside the house, where the gas boiler is now, or B) in the garage? Unfortunately, the heat pump could not produce hot water in the garage because there is only a cold water line to the garage. Or are there any solutions? I would prefer the garage otherwise.
I hope you can help.
Thank you.

Does anyone have experience with the Panasonic Geisha air-to-water heat pump? It is relatively affordable. How is the domestic hot water production implemented? Are there square hot water tanks? The round ones don’t look very elegant. Our plumber from the well-known area is enthusiastic about them, saying they are top-quality units at a good price. Unfortunately, the conditions for dealers are apparently not great, which is why he mostly installs Wolff equipment (simply a better margin). I’ll quote his statement.

What a tip 🙄
As an amateur, you don’t mess around with water or electricity in the house! The advice is to order the appliances from abroad. The conditions there are somewhat better. But everyone has to decide for themselves.
In the future, we will have to do much more ourselves. At least then I know exactly what I have done.

You won't find a (reliable) tradesperson... You have to bite the bullet. I will assemble them entirely myself, of course with the help of a system installer.

Everyone can decide for themselves here. Over the past years/decades, I’ve always had good results with this. You don’t get any less knowledgeable from such a project, either. At the very least, you realize how many so-called experts and specialist companies are out there in the market.
