Household electricity consumption - consumption values for comparison

: Yes, correct, only household electricity, without heating. (We also have a gas heating system). 2000 kWh household electricity per year? Respect! We didn't even manage that consumption before with no children in the rental apartment. We were at about 2500 kWh per year. And the fifth.... wow! Do you have a photovoltaic system with self-consumption?

We used to have 1800kwh for three people in the rented apartment. Switched all lamps to LED, no desktop PC (use notebook), entire TV system turned off with a wireless socket when not in use. Then it works, at least in a rented apartment.

Do you have a photovoltaic system with self-consumption?

No, we decided against that... because in my eyes it would never have paid off.

No, we waived that... because in my eyes it would never have been profitable.

Interesting, for us it is profitable because we buy electricity at 25c and sell it for 12.6c. Is your photovoltaic system significantly older, do you get more per kWh?

My values from 2017:

180 sqm living space, 85 sqm basement, 60 sqm garage. Kfw 70 building from 2013

Controlled residential ventilation 577 kwh Sole ground heat exchanger (for the controlled residential ventilation) 229 kwh Heat pump 3938 kwh Household electricity 4,395 kwh (I have a lot of home technology that is constantly running NAS, router, multiple access points and cameras, DECT repeater, KNX bus, iPad visualization, etc., that adds up) Total consumption: 9,139 kwh, of which 1,915 kwh are covered by our photovoltaic system, so at least 21%. If my wife wouldn’t always only run the washing machine and dryer at night, it would probably be even more.

I think the photovoltaic system is definitely worthwhile, the 1,915 kwh save me almost 480€ per year, plus 620€ feed-in tariff for the surplus. That makes 1,100€ annually, the system with 5.9 kwp cost 6,600€.

Thank you. I'll take a look. The heat pump (it's a Vitocal 309g) must also have consumption information.

I have a Vitocal 333 running.
