Hello everyone,
I would like to hear your opinions on the above-mentioned question, as two electricians have different views.
Conditions:
- Ground source heat pump 8 kW with cooling function for summer
- Photovoltaic system SE+NW 16.38 kWp
- New single-family house with 193 m² (2,076 sq ft) living area
We now want to determine the size of the distribution board. Of course, it is also crucial to know how many meters I will need and how much space should be reserved for them.
One option is to go with 3+1 meters to be ready for everything. However, there is a price difference depending on whether you can leave out two meter slots and have only 1+1 in the panel.
Additional costs come from meter rental fees and usually the higher basic charges, which reduce the savings from the cheaper heating electricity tariff. If I roughly calculate this, you would need to consume quite a lot of electricity (single-family house > 6000 kWh) to benefit significantly from the lower tariff. Does anyone have a clear example calculation?
The questions are:
1. Is the heating electricity tariff generally worthwhile, and from what consumption level? If it’s currently not worth it, should space still be reserved? Who knows how the difference between tariffs will develop.
2. Can the electricity generated by the photovoltaic system be used both for self-consumption within the house (household appliances, etc.) and for the heat pump?
Thank you for your assessments. I am happy to answer any questions.
Good luck

Oh ok, then I probably won't need to purchase an additional 2000 kWh either.You’ve just invested 500,000 +X € in your house, so I wouldn’t worry about buying an extra 100 or 200 kWh of electricity. And regarding 8 kW, it actually varies.
We’ve just been through our once-in-a-century flood and might be facing a once-in-a-century winter next.
