Air-water heat pump current consumption and data

I don't know if it's because of age or the underfloor heating, but since we've been living here, I've somehow become more sensitive. When I wake up in the morning and it's only 21 degrees in the living room, I notice it immediately, or 23 is immediately way too warm.

I don't know if it's due to age or the underfloor heating, but since we have been living here, I have somehow become more sensitive. When I wake up in the morning and it’s only 21 degrees in the living room, I notice it immediately, or 23 degrees is instantly much too warm.

I can confirm that 100%. That may be a very subjective perception. In the "old house," uninsulated and from the 80s with radiators, I was constantly fiddling with the radiators. It can't be that the temperature was that constant there. And now I notice every deviation of 0.5 degrees up or down very, very clearly. Maybe it’s also because the more constant something is, the more noticeable deviations are.

01.10. - 11.03. 1796 kWh electricity for the heat pump. Could be less, the COP is unfortunately still only 4.2 200sqm, KFW55, controlled residential ventilation, 4 people. Geothermal energy via probe. Target temperature in the house 22 degrees. +-0.5 works as well

My sympathy for the consumption is limited :p (Unfortunately you wrote). I hope that I can report such consumption next year as well.

1.10-1.03.21

2780kw electricity... that's a lot, it was cold after all.

Average about 19kw per day including hot water.

Cross-comparison:
1.10. - 1.03. :
1050 m³ gas => approx. 400-450€

No, I'm not from the gas lobby :p
But I find the thread and the exchange very interesting.

: do you have the additional cost of geothermal compared to air-water heat pump in mind?
Does photovoltaic also make sense with geothermal? (financially, not ideologically :p)
