Electricity consumption at home, what is your consumption?

I think he definitely has a 5k household. That leaves 5k for the pump. Fits.

Assuming the figures are correct, I would say something is off.
If it is 5000kWh electricity consumption for the heat pump, it would either be about 20000kWh heat output that the house required, or the heat pump operates with an annual performance factor between 2-3.

If, as previously assumed, the delivered heat output is 10000kWh, there would probably be no problem.

Reliable figures are needed to classify this properly.

Assuming the numbers are correct, I would say something is not right.
If it is 5000 kWh electricity consumption for the heat pump, it would either be about 20000 kWh heating output that the house needed, or the heat pump is running with a seasonal performance factor between 2-3.

If, as previously assumed, the delivered heating output is around 10000 kWh, there would rather be no problem.

Reasonable numbers are needed to classify this.

With 240 m² of heated area, the 5k could indeed be correct. That would be merely 90 euros heating costs per month. Could be a seasonal performance factor of 3.5 to 4 and that would be right within the average!

Depending on room temperature and location, that could even be quite good! We simply know too little.
It can hardly be heating output, such an efficient pump doesn’t exist :D

Interesting thread, I already felt bad with our 200W base load :p

Since the beginning of October, we have consumed about 780 kWh. Currently, exactly 78 days have passed since the installation of the SMA Home Manager, so roughly 10 kWh per day (2 adults and 2 small children).
Of that, 213 kWh is self-consumption + 207 kWh from the battery storage and the rest purchased.

The photovoltaic system generated 9837 kWh throughout the entire year (10 kWp, SSO orientation with flat roof 8°).

I have no idea how such a low consumption is possible! There’s no heat pump involved, is there? Do you heat with gas?

I’m just asking because I didn’t have the heating on until December 12th and until then we always had a consumption of 450-500 kWh per month and we were already very careful to only draw electricity when the sun was shining. See screenshots.

We have about 150kwh per month :D but we heat with gas.

We don’t have a heat pump, I forgot to mention that. We heat our 150sqm with district heating (Kfw40+). Since the beginning of August (move-in), we have used 2000kwh of heat, hot water and heating included. With an annual performance factor of 3-4 something, that would be around 500-600kwh of electricity.

The hot water could partly explain the difference, you do that with the heat pump as well, right?

My plan to cover the ongoing heating and electricity costs with photovoltaics might actually work out: It looks like we get by with 6000kwh of heat per year. The goal for electricity would be to only have to buy about 1/3. The kwh of heat costs me 5.1 cents, no basic fee, so about 300€ heating costs per year. Electricity at 30 cents (basic fee left out) would then be 360€ or a bit more. This matches pretty well with the returns if the photovoltaic system always produces between 9-10 Mwh per year.

We could save if we optimize the base load. At 200W continuous load, that’s already 1700kwh per year or almost 50% of consumption. There’s a bit of luxury in that: Synology, a bit of smart home, ventilation, network, cameras...

Maybe your base load is pretty high as well?

With 240 m² of heated area, the 5k could definitely be accurate. That would be just 90 euros in heating costs per month. It could be an annual performance factor of 3.5 to 4, which would be right in the average!

For a KFW 55 of this size and heat pump, I would assume that 5000 kWh electricity consumption does not necessarily indicate a good setting of the heat pump. But you can, of course, just let it run.
