Your current heating consumption

It’s not about oil. It’s about a house from 1979. That’s what I mean by progress being a snail. Because six thousand liters are really okay for 430 sqm as an annual consumption. Oil has also almost cost a euro per liter, it’s very volatile. I wouldn’t choose oil anymore and won’t do that either. Only, in the new building, we will hardly manage to halve our heating costs.

Morning;



I don’t quite follow your calculation:
Your heat pump is supposed to produce 60,000 kWh of heat for €2000?
Quick calculation: for €2000 you get about 8000 kWh of electricity. That would be an annual performance factor of 7.5. For that, you would probably need a COP in the range of 9-10 (as an annual average).
So either you’ve found a way to get cheap nuclear power from France, or the perpetual motion machine as a heat pump, or you’re sitting on a hot spring...

Realistically, I would estimate the electricity consumption of a heat pump for 60,000 kWh of heat rather to be a minimum of about 15,000 kWh. That would be just under €4000 in costs...

Or am I missing something here?

Best regards,

Andreas

With us, heat pump electricity costs 18,x cents, so for 15,000 kWh less than €3,000
