Determine the consumption of air-to-water heat pump from the total electricity consumption

Where do you read that off? Are there any other meters besides the main electricity meter? Note! 12,082 and 2,477 MWh!

Exactly: On the display for the heat quantity it says "MW" meaning megawatts and the dot is to be interpreted as a comma. That makes 12,082 kWh and 2,477 kWh.

No, it says MWh there! PS: A point already clarified doesn't need to be explained again, especially if it is still wrong. :cool:

I have a question about the topic, independent of the actual post. We have been living in our newly built KFW55 house with 9.9 kWp photovoltaic system since the end of October. We have 2 meters, see picture, the left one currently shows 1324/4691 kW, the right one 442/4912 kW, how is this to be interpreted? The SMA Homemanager was installed at the end of December, but with it I can only read the performance of the photovoltaic system and the consumption without the heat pump.

On the left is heat pump, on the right Hamburg: I would say you have a heat pump tariff and the left meter shows the consumption of the heat pump and the right one the household electricity. Was that your question?

Clear so far, we have 2 tariffs but I do not understand the different feed-in values respectively... left 4691, right 4912

These are not feed-in but consumption data, are they?
