Reed, in a year - that is understandable. I use pure electricity about 4 MWh and additional 3 MWh in solid fuel for the heating season for our 170 sq.m. (no heat pump, just pure electricity through boiler). Just it seems it is much warmer in your location, we get temperatures down to -30C

Thank you very much for sharing your experience. Though 4 MWh of electricity seem quite excessive having in mind its +12 degrees in Durnham now. Nonetheless, energy efficiency of the buildings probably differ (we have close to passive house) and only two people using hot water. Anyway, once again, thank you for sharing your experience!

It helps. Do you use cooling? We have 250l tank of which currently we use only half. If needed, we can turn on 12 kW pure electric heating, but even with -20C 4kW is sufficient P.S. 4058 kWh thats electricity or heat produced?

I wanted to ask a bit offtopic, The users of this heatpump, are you satisfied with it? Thinking to choose this heatpump, as its price for 7kW is less than 4k, which seems very good offer, as warranty for inverter in my country is 10 years. Though LG heatpumps don't have much presence in my country, thus not much reviews and experience of users.
