We had about 200 sqm and 5 people in permanent home office in 2021, 6,000 kW.

Also have water collectors. So it matches with you.

hm.. unfortunately I did not record the heat quantities last year. I have only been recording them since the beginning of September this year.

The values for this year:

September: 55 kWh heating / 102 kWh hot water
October: 138 kWh / 101 kWh hot water
November: 848 kWh / 150 kWh hot water
December: 835 kWh / 131 kWh hot water

As a forecast for 2022, the meter app (EHW+ Android) tells me the following values for 2022:

Heat quantity heating: 5707 kWh
Heat quantity hot water: 1465 kWh

We heated the living spaces to 21°C, bathroom about 22°C.

The hot water is heated to 45°C here.

Currently, the desired flow temperature is 32.4 °C at an outside temperature of -0.6°C.

The screed heating phase should not be included in the consumption, as we already had that in 2020.

Thanks for the tip, I will look for comparative values there. I don’t think the heating element runs that often. However, I’m not sure which value corresponds to the heating element, but I believe that most running times come from thermal disinfection.

2nd heat generator: 153 hours (since the heating activation around October 2020)
Flange heater: 238 hours (since the heating activation around October 2020)

Hi.
It would be nice if you also compare the consumed electricity to the generated amount of heat. Then you can say more.
Regards
Currently - 10°C...Brrr

I would now prefer that over today's weather with just below zero, wind, and heavy rain. Although the -17 on Monday morning certainly wasn’t much fun either ;) That actually sounds quite reasonable. I just don’t understand how from a good 7000 kWh of heat you end up with 5700 kWh of electricity. That would mean the heat pump has a seasonal performance factor of 1.22. Do you have the electricity consumption for the individual months this year?
