Cold local heat with ground source heat pump

Not at all. This depends on the heat pump, the heating system design, and you. I simply assumed an annual performance factor of 4, which should definitely be achievable with geothermal energy. If the heating system is well designed, 4.5-5 are also possible. Calculation means that you generate four kWh of heat from one kWh of electricity. If you even get five kWh from one kWh, the price for the work would correspond to an electricity price of 30 cents. Paying both, i.e. one kWh of electricity for operation plus the labor costs for four or even five kWh of heat, would be madness.

Do you have more precise information about that? This colorful info page does not reveal much. Who supplies the electricity for the heat pump? Since the price of 5.95 cents probably refers to the heat generated, the situation arises that the more efficient the heat pump works, the more your provider earns from it. Incidentally, 500 euros per year is already what many people with well-insulated houses pay in total for their heating consumption.

Hello everyone,

I hope you can help me. In our development area, there will be a cold local heating network, where the energy supplier supplies the heat pump in the house via deep drilling and a connected ring main network.

Now we were considering integrating a photovoltaic system to supply the heat pump with self-produced electricity. So far so good! Today we received a letter from the energy supplier stating that for billing reasons it is not possible to use the self-produced electricity for the heat pump.

Here is the original wording:
“As you have correctly noted, for billing reasons the entry of self-generated electricity from a photovoltaic system is not feasible. By feeding it into the system through us, there would additionally be the disadvantage that the full Renewable Energy Sources Act surcharge would apply to the entire electricity, so that the advantage of self-produced electricity would no longer be fully realized.”

Has anyone heard anything similar? Is it really not possible?

Then a photovoltaic system almost doesn’t make sense anymore. And nowhere in the contract conditions does it say that you cannot use the self-produced electricity for the heat pump.

Thank you very much in advance!
