New Viessmann w2w ground source

"Viessmann unveils ground-source heat pump for space, water heating
Viessmann has developed a heat pump for residential applications that can produce between 5.8 kW to 10.4 kW of heat. It has the capacity to heat 220 liters of domestic water, with a coefficient of performance (COP) of up to 4.8 for space heating and 3.14 for water heating."

I would love that, but cant imagine the startup cost lol.

I'm sure its of the highest quality...thats a given.  Its the installation of, that is the tricky, obstacle course.  Mad Dog.

Progress... but as @Mad Dog_2 says, it's the installation... at that COP, though, at least it breaks even on energy costs around here.

R410A refrigerant, so just another entry into a crowded field of W2W heat pumps. I do like the 65 C leaving water temperature! Nice looking probably high end product. The ground loop cost is the challenge, the COPs don't matter particularly much above ~3.
