According to common forums, a well-adjusted heat pump needs about 2 to 3 kWh per day for hot water. About 1000 kWh per year. Heating about 1500 to 2000. In total, best case 2500 kWh, at a minimum electricity price of 21 cents you end up with 40 to 45 euros total. But this is all in the ideal range. I say 95% of installed heat pumps will never achieve these values.

Don't be fooled here, this also works wonderfully with an air-to-water heat pump without costs exploding.

We have a kfw55 house at 950mNN and also in the deep winter 23 degrees throughout the entire house with an air-to-water heat pump, underfloor heating, and controlled residential ventilation.

That's pretty cool. Either you need so little hot water or you can break the physical limits. I don't believe that your heat pump produces more than 4 kWh from one kWh of electricity if it is an air-to-water heat pump. We need about 200 liters of hot water daily for two people, some also cools down unused. That is 12 kWh; with a COP of 4, that's effectively 3 kWh. So you would have to manage with 70 liters of hot water, and the storage would have no losses.
Please explain that to me because not even one person could take a warm shower...
