Installation of one or two electricity meters?

Heating requirement of 3250 kWh/a

Amazing - okay, I looked it up:

11700 kWh heating requirement

And here:

3900 kWh electricity requirement for heating and hot water.

Would you have something like this for me too? Have you been moved in for that long already?

Regards

Would you also have something like this for me? Have you already moved in that long?

As I said, we are talking about calculated demand. Move-in might be in January. And yes, calculated is not necessarily the same as real, but basically the expectation is that after 1-2 years we will be roughly in that range. What kind of house do you have? Size, standard?

We need for 3 people heating, hot water and electricity

I find the hot water demand quite considerable. There are two of us, but you have triple the heat demand for hot water? Wow, and I already feel guilty when I leave my Raindance shower running longer. I shower at home every day, my wife a few times a week at the gym, which is surely overcompensated by regular bathing.

In the last 12 months, I have consumed for hot water:
1668kWh heat
674 kWh electricity

Do you run circulation or the legionella program every day?

By the way, I just realized that the COP is somehow really bad, but that shouldn’t be the topic.

: would you like to show me your heating curve and tell me approximately how many m² you heat? I am currently considering my heat pump and wondering what values it should achieve at 0° and -10°. Thanks Do you also have a fireplace?

What kind of house do you have? Size, standard?

180 sqm
KFW 55

I find the DHW demand considerable.

Me too :oops:
And there are only two of us (were in 2021) and we only bathe 1-2 times a year.
I can only set here (I think, anyway, I have to check again) when DHW should be produced, with a 24h segment dial.
Then heating is done at 5+6+7 am and 16+17+18 pm.

Did you run the circulation or the Legionella program every day?

I will take a look at that.

Do you also have a fireplace?

No - also no exhaust (kitchen), but controlled residential ventilation

180x35 = 6300 kWh/a calculated heat demand, so you are pretty much exactly at the demand. A large house and one level lower in the standard make a difference. The COP=3.45 is rather moderate and I also find the amount for hot water way too high.
