Air-water heat pump current consumption and data

Yesterday, the heat pump consumed 21 kWh at our place, last night it was -14C and currently only -8C AT

It is not bad, but there is certainly still potential for improvement. ERR are set to 4-5 and not completely open. I need to get in touch with my heater technician and try to optimize. Hot water is set to 48 degrees.

A really stupid question. Consumption 2018 approx. 3520 KW 2019 approx. 3460 KW 2020 approx. 3440 KW

A really stupid question: How can I tell from my energy certificate whether I have KFW 55 or not? (please don’t stone me) o_O

Primary energy value qp [kWh/m2a] less than or equal to 49.5, then kfw55 otherwise only Energy Saving Ordinance 2016 up to 67.4. If you are above that = old building :p and Average u-value H’t [W/m2K] less than or equal to 0.259, then kfw55 otherwise only Energy Saving Ordinance 2016 up to 0.370. If you are above that = old building :p Both values must be met.

:cool:Thanks! :)

my primary energy consumption: 43.1 (kWh/m2a) ----- that would fit
U-value building envelope H`t : 0.27 (W/m2K) ---- just missed it ;)

so, not quite fulfilled.

And which amount of heat generated?

The house was noticeably cooler this morning, I only had 21 degrees in the living room. I thought the heat pump would regulate itself but apparently that was not sufficient. I then increased the heating curve by 2 degrees because I was cold. Now after 24 hours, 42kW of electricity through 128kW of heat including hot water at -14 degrees last night. Had 2 heating cycles lasting over 7 hours.
