Air-water heat pump current consumption and data

Today I took the time to add up my data, I have been recording it for a year... At the beginning daily, then of course no longer. Over the whole year, I actually used 3791 kW for 250 m² of heating area. The internal heat meter shows about 13820 kW of heat produced. Thus, I have an annual performance factor of about 3.7. I am quite positively surprised :) Our electricity meter has a connection for the network, what do I need for that and what can I see there?

Throughout the whole year, I actually managed with 3791 kW for 250m² of heating area.

Did you also perform the evaluation on a monthly basis? I am currently in the process of calculating my planning for a photovoltaic system with storage and still have open questions regarding the monthly values for the heat pump and at what size a storage system pays off.

Yes, I also have them monthly, wanted to create nice graphics with them, but I can’t do more than lines and a few formulas in Excel. I just have to take the time, but it’s not that easy with 2 kids and the lockdown.

I also did a rough calculation for December, extrapolated to 31 days we are at 15.79 kWh per day (approximately 490 kWh total). Since 18.10. until today we have consumed 931 kWh of electricity and thereby generated 4088 kWh of heat, coefficient of performance 4.39, heated area 218m². Can't complain.

That's good! Where is your house located, which federal state?

Middle Franconia in Bavaria, 450m above sea level. The standard AT is at -13.2.
