ᐅ Additional meter for heating electricity tariff: yes or no?

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

We decided to leave it out and have no regrets so far. ;-)

HeimatBauer24 Oct 2023 14:28The electrician promised us the larger enclosure firmly, and we have plenty of space, but he ended up installing the somewhat narrower enclosure, which already caused significant extra work during the installation of the photovoltaic system. I would like to connect some self-laid electrical cables inside it, but the space is very tight.
So, I would gladly retrofit the larger enclosure today if that were possible.

Do it, and you’ll be prepared for all the technical upgrades that might come along in the next decades.

RotorMotor24 Oct 2023 20:40My prediction was and still is that more time-based tariffs will emerge rather than tariffs based on the type of usage.
For electricity providers, it really makes no difference whether the electricity is used for heating, a car, or an oven. What matters more is when electricity is cheap or expensive on the market.
This is somewhat reflected in heating tariffs, where power supply is cut off when electricity prices are high for the supplier. Currently, this is still quite basic, relying on fixed cutoff times. I expect that with a smart meter, this can be managed much more effectively.

Westfale010127 Oct 2023 11:24Our heat pump tariff is about 10 cents cheaper, so I even think that the tariff will still be worthwhile for a photovoltaic system without storage, since a bit more electricity will have to be drawn in the older building during the darker months.
Besides that, I also expect the political framework to change in a way that these electricity-related issues will be subsidized more than coal/gas.
