Hello everyone,

I have just received the billing from the energy supplier and wanted to hear your experience/opinion.

House: Brick solid Kfw 70 built 2016
Number of people: 2 adults 1 toddler
Area: 270 m2 (180 m2 ground floor/upper floor and 90 m2 basement)
Heating: Viessmann Vitocal 300A (13 KW) with underfloor heating.
Annual consumption including hot water was 6300 KW/h

Do you find the consumption reasonable?

That is about 150 euros per month. That is definitely too high. I would estimate it should be at least one third less.

kWh electricity? or kWh heat? And with household electricity?

Heating buffer and individual room control? Heating element deactivated? Underfloor heating?

6300 kWh electricity
Individual room control
Household electricity runs through a separate meter.
Heating element activated

The question is when does the heating element activate for you? If it is always on (which makes no sense) then I can understand the consumption, otherwise I find it too high

One cannot really judge that properly at all. If you heat the entire place including the basement constantly at 23°, the consumption might even be very good.
