Electricity costs for a KfW QNG 40 house

Everything I write always includes hot water as well. Now you need to start doing some calculations yourself. You have received all the necessary information in my last posting. So you should be able to figure out a from - to, I’m not going to do that for you anymore.

P.S. You have a really high water consumption.

880 kWh district heating.

Is that really correct? That seems extremely low to me, especially for an apartment housing 4 people. If that is true, the neighbors are heating significantly for you, and you should expect considerably more in your own home.

I'll send my 2022 cost statement.
We have underfloor heating and live on the ground floor.

1. believe 98% that the billing is incorrect or that you get by with 16°C RT and heating through the neighbors (aka freeloading). 2. no one can answer this question for you. Only you know how hot, often, and long you shower or bathe.

Regarding 2, there are data sheets from shower manufacturers. With a bit of googling, you can then determine how much energy you need to heat water to the desired temperature. With a performance factor of 3, you get the electricity consumption.

I’m sending my cost statement from 2022.

That is just 9.4 kWh/sqm. Heat to living area, mind you. For comparison, my energy consultant calculated an electricity demand of 12.4 kWh/sqm for my 40s building envelope, then you add the annual performance factor of the heat pump, and that refers to the larger usable building area.

Hello WilderSueden,
for 2021 we also have a similar cost statement.
According to the cost statement, our current apartment is 93 sqm.
