One m³ is about 10 kWh. With gas, it is still interesting what the [Solarthermieanlage] contributes - this is simply not accounted for in the displayed consumption even though it is there.
My house without a basement required on average about 40kWh of heat/day in frost-free northern regions in January, including 10% hot water share.
That would be approximately:
- 4m³/day gas at 100% efficiency
- 10kWh/day electricity at a coefficient of performance of 4
- 4 liters of oil at 100% efficiency
One cubic meter is about 10 kWh. For gas it's still interesting what the solar thermal system contributes – that is simply not shown in the displayed consumption even though it is there.
oh yes, I actually wouldn’t have thought of that in summer

how many sqm and what temperature inside the house?
I actually just wanted to contribute something about the energy sources. These comparisons don’t bring much.
It is about 150m² living space and approximately 21° room temperature on average +/- 1-2° depending on the room and usage. On cold days about a year ago with outside temperatures down to -8°, it was 70kWh/day. A very similar house a few kilometers away has almost identical monthly consumption according to the database as mine.
21.01. Total 23 kWh - of which 13.4 kWh for our heat pump
In the house, we have approximately 22-24 °C in all rooms from the basement to the upper floor
Hot water 44°C hysteresis 3°C
We still have snow here AT always below 0°C / 940mNN 180m²+basement
13 kW? For 180m2 plus basement? And then nearly at 1000 meters altitude? What kind of heat pump is that, ring trench collector or brine?
Could you also add your type of heat pump for comparison?
