Electric meter - one or two?

There are plenty of providers who do not exclude it. However, unfortunately, they usually do not belong to the 5 cheapest. After that, you will find something quickly.

Questionable, however, is whether such a surprising clause would still withstand the highest courts today, where a Thermomix and toaster together almost create more load than a heat pump. The clause dates back to the days of storage heaters and electric power as 1:1 heating electricity.

Side question: Is a photovoltaic system planned? Then it is usually not worth

If you switch the heat pump to the other meter in 5 years and the other one is no longer used, do you still have to pay fees?

In the multi-family house, the owner of the house pays fees even if an apartment is vacant. As long as the meter is not completely deactivated but only the heat pump is switched, you probably continue to pay.

How do you handle that best then?

Ignore.

If the meter is definitely no longer needed... have it removed. = 0 ongoing costs

Ignore.

Exactly; and if you have a heat pump + photovoltaics, a single meter is certainly the better option.

Ignore.

Presumably. But then please also point out the existing residual or process risk. The decision should be made consciously. I am looking forward to the outcome of the first trial.
