Is the electricity consumption including hot water?

From October 18th until today, November 20th, we used a total of 290 kWh including hot water for four people.

KfW55 standard, solid construction, controlled mechanical ventilation, and 218 m² (2340 sq ft) of heated floor area.

Consumption in our home since 01.09.2020 including hot water:
Electricity 218 kWh (but with a ground-source heat pump)

The energy-demanding months are still ahead... (Dec-Feb)

Yes, including hot water. We used 430 kWh, same size and also KfW 55. But it really depends a lot on the location and heating habits.

That is extremely low, even for ground-source. We need about 3 kWh on average just for hot water.

Our house is rather warm, at least 22 degrees Celsius (72°F), with bathrooms and living areas at 23 degrees Celsius (73°F). The average outside temperature is -13.2 degrees Celsius (8°F). We have already had a few nights with frost.
