Heat pump consumption 2019 on a monthly basis

At least today I finally set the hysteresis so it doesn't heat the water 7 times a day... so far I've probably wasted several thousand on electricity, many thanks to my "Heizungsfachbetrieb"

I have now consumed 3350 kWh in the first year. Hot water + heating. 200 sqm living space, no stove, no controlled residential ventilation, just missed KFW50. 9kW air-water heat pump not modulating. All ERR off. Region Lower Franconia. Your hot water consumption seems quite high to me. Do you have a circulation? Otherwise, your heating also seems to have turned off quite late and turned on quite early in October. I set my heating limit to 12 degrees average during the day and never froze at any time.

I would like to start a new comparison thread and get to know your consumption. I am not quite satisfied with mine. KFW55 heated area 200 m2, underfloor heating Standard rooms 19 degrees, living rooms 22 degrees, bathroom 23 degrees Air-water heat pump with central controlled residential ventilation Hot water temp. 50 degrees Data recording unfortunately only since April 2019

4 degrees temperature difference in the new building? Either your ERR controls are killing themselves and destroying the efficiency of your pump, or you have individual rooms turned off and have to run high flow temperatures because the bathroom and living rooms automatically heat the other rooms. That is also an efficiency killer.

Either your ERR are regulating themselves to death and killing the efficiency of your pump, or you have individual rooms turned off and have to run high flow temperatures because the bathroom and living rooms automatically heat the other rooms. This is also an efficiency killer.

So the ERR are set to 2-3 in the rooms that are not used and to 5 in the living rooms. Could this perhaps be the cause of the inefficient operation?

Be careful Here ground source heat pumps are compared with air-to-water heat pumps, the ground source heat pumps have a much better annual performance factor. However, they also cost significantly more due to the drilling.

Turn them all up and lower the heat pump until you feel cold.
