Hello, in 2020, we consumed about 6,800 kWh of electricity. Of this, 1,750 kWh was self-consumption from our photovoltaic system. This means our electricity purchase from the grid was 4,062 kWh. Since we have an air-to-water heat pump, the heating also runs on electricity.
How can I now separate the electricity consumption of the air-to-water heat pump from the overall costs?
We have a meter on the electrical distribution board showing 1,294.59 kWh. Additionally, there are two heat meters installed (12,082 and 2,477 MWh).

Where do you read that? Are there additional meters besides the main electricity meter?
Note! 12,082 and 2,477 MWh!Exactly: The display for the thermal energy shows "MW," meaning megawatts, and the period should be read as a comma. That makes 12,082 kWh and 2,477 kWh.

PS: A point that has already been clarified doesn’t need to be explained again, especially if it’s still wrong. 😎

Badener19708 Jan 2022 16:54I have a question related to this topic, independent of the original post. We have been living in our new KFW55 building with a 9.9 kWp photovoltaic system since the end of October. We have two meters, see the picture; the left one currently shows 1324/4691 kWh, the right one 442/4912 kWh. How should this be interpreted? The SMA Homemanager was installed at the end of December, but with it, I can only read the photovoltaic output and the consumption excluding the heat pump.

On the left is the heat pump, on the right Hamburg: I would assume you have a heat pump tariff, and the left meter shows the consumption of the heat pump while the right one shows the household electricity. Was that your question?That’s clear, we have two tariffs, but I don’t understand the different feed-in values... left 4691, right 4912Similar topics
