Nanana Everyone can make a mistake sometimes. In the second calculation I divided the delivered heat quantity by the (presumably) supplied heat quantity. Thanks for the unfriendly pointing out.And with 1000 kWh less "total consumption" it is then... The calculation doesn't really add up. that remains his secret. Yesterday, with an assumed 3800 kWh instead of now 2800 kWh for heating, the annual performance factor was still about 2, now it is supposed to be about 5. :rolleyes:
Here are the promised pictures.
The heat meter with the reading ~2,400 is disconnected from the pipe that goes into the water storage.
Of that, 1,750 kW is the self-consumption of our photovoltaic system.
Heat meters installed. (12.082 and 2.477 MWh).
Where do you read that from? Are there any other meters besides the main electricity meter?
Note! 12.082 and 2.477 MWh!
And the meter on the power rail? I thought that was the yield from the roof? Then please show the table at the end of the month…The data I take from the app of the photovoltaic system
