Air heat pump and electricity consumption

A short update on the water level - uh, electricity consumption - from us as well. We heat with a geothermal heat pump.

We were told that we have to expect 8,000-10,000 kW in the first 2 years, then 6,000 afterwards. I’m curious if that’s true, but I would tend to say it’s estimated a bit too high.

Our pump was started up at the beginning of September. However, at that time the heating was done completely electrically for heating up and drying the screed (in my opinion, this was the first 1,500 - 1,800 kW). After we turned down the heating during our own work (painting), we moved in at the end of November. Until the really cold days (end of December), the hot water was not heated by the electric backup heater.

So, after all this background, here is the current status: we have consumed about 2,850 kW since the start of the heat pump. Now in December, I checked the meter every morning. Currently, we have a daily consumption between 20 and 26 kW on the pump – depending on whether the hot water tank needs heating again. This consumption is during the current cold season. I’m curious how the consumption will be when spring or summer comes. Let’s see where we will end up.

Oh, by the way – the house is KfW70 with a size of more than 170 sqm.

I wouldn't carve that in stone either...

I need more details.

My father recommends the gas condensing boiler, and then to install something efficient and alternative in 10 years.

especially in the current times, where no precise forecasts about the price development of individual energy sources are possible...
