Heat pump on separate meter or together with household electricity

Heat pump 19.0 cents no GG!).

With Maingau, however, there is only one single provider who does not charge GG.
In the end, prices for heat pump electricity will rise sharply in the future because, due to the increasing share of photovoltaic in winter, not as much electricity is available and must therefore be purchased more expensively from reserve power plants.

I'd rather stay with Hamburg-Strom. I have accepted the terms and conditions of Grünwelt/Stromio, but of course did not read them so carefully ops:, that operating a heat pump is not allowed. But I act like , if it bothers the electricity provider, then they should cancel.

Thank you very much.
Do I still save something if, according to the contract, two meters were provided?

One quick question about consumption:

Is it assumed to be about 2000 kWh for the heat pump’s consumption?

And about 2000 kWh for other consumers?

How and what should one answer you to this question?
The electricity demand depends on many things.
According to which standard did you build (which energy saving ordinance was the basis)? Do you have KfW70; 55; 40; 40+? How much heated area do you have? Your personal electricity consumption behavior? Do you have a photovoltaic system? etc.

You have already been given some numbers here. Without background information. You can hardly deduce anything from that.

We built according to KfW 70 old energy saving ordinance (built in 2014) for about 170 sqm.
In the first year, we had a heating electricity consumption of about 5,000 kWh. However, this includes the value from the heating-up phase (screed drying). In addition, we have made some fine adjustments in recent months. I estimate the next bill will be between 3,500 - 4,000 kWh – possibly even below that.
We had about 1,800 kWh of household electricity consumption. But we have photovoltaic on the roof and a "strong" self-consumption rate.
In general, we have always had a low household electricity consumption (compared to our acquaintances), even in the rental apartment.

As I said – these numbers will probably not be of much use to you.
For household electricity, it is best to take your current consumption as a reference. New appliances may save electricity; additional consumers (e.g., for outdoor facilities) will increase it somewhat.

With Maingau, however, there is only a single provider that does not charge a fixed fee. In the end, prices for heat pump electricity will rise sharply in the future because, due to the increasing share of photovoltaics, less electricity is available in winter and therefore has to be purchased more expensively from reserve power plants.

That's true - Maingau has no fixed fee. I hope your prediction does not come true. Because, contrary to my previous behavior, I would only be reluctant to switch (having no fixed fees is something). If they raise prices, you have to see to what extent the savings on meter costs are "eaten up" by an increase.
