we are two units and handle our billing ourselves. This year is the first time.
The house has solar thermal panels (collectors on the roof) for hot water. Heating is provided by an air source heat pump.
We are now wondering what is the best way to calculate hot water consumption in terms of electricity for the heat pump?
For the heating circuits, each unit has a heat meter to measure water consumption separately and a heat meter for hot water.

I've made some progress 🙂 Now it's just about the hot water. We have a solar thermal system for water heating. Obviously, you can't redirect the sun. We would like to redirect the pump electricity. Is it possible to estimate how many kWh of pump electricity are used per cubic meter of water?
