ᐅ Photovoltaics and Heat Pumps – Meter Confusion and Cost Issues

Hello everyone,
does anyone here use an air-to-water heat pump combined with a photovoltaic system?
I’m currently unsure whether we will get a dual-tariff meter / two-rate meter, or just two separate regular meters (one for household electricity, one for the heat pump electricity).
We have an all-in-one unit with controlled living space ventilation plus air-to-water heat pump integrated.
Now I saw the heat pump tariff from EWE, which states “18 hours of operating time per day,” something about a 6-hour interruption and a buffer. This probably isn’t compatible with us, as I have never heard that our device should have no power for 6 hours during the day.
Does that mean I generally cannot use the heat pump electricity tariff? Or do I just have to choose a different provider?
On Check24, I find several heat pump tariffs. Many of them show the same cent price for peak and off-peak times. Does that mean I can use these tariffs even if I only have a “regular” separate meter for my heat pump (not a dual-tariff meter)?
And can someone tell me how much an additional meter for the heat pump costs? I keep reading that heat pump tariffs are not always worthwhile because the extra meter costs more. Does this only apply to the dual-tariff meter, or does a regular second meter also incur an additional monthly fee?
Last but not least – how does it work if you have a photovoltaic system but also two meters? We definitely want to use the photovoltaic electricity for both – the air-to-water heat pump AND the household electricity – to maximize our own consumption of the PV electricity. Is this easily possible with two meters? How is that typically set up?
Sorry for the many basic questions. I’m trying to get a better understanding of this topic and our electrical contractor is not our favorite trade – some might remember the previous troubles. That’s why I want to keep an eye on it and understand exactly what they are installing.

It’s best to check with your local utility provider. They are responsible for installing the meter.
As far as I know, the requirements can vary from place to place or between electricity providers.
I have also seen cases with three meters when you want to feed electricity back into the grid as well. For example, an air-to-water heat pump + photovoltaic system + grid feed-in.

We insisted on having only one meter.That would also be my go-to alternative if it can’t be done any other way. Being able to use the photovoltaic system for all consumers is much more important to me than the heat pump tariff. Whether the tariff is worthwhile still needs to be calculated first.
However, I can’t find anywhere what the additional meter would cost me, which makes it difficult for me to calculate whether the heat pump electricity tariff would be worth it or not.

A meter cascade could also be an option.
In the "other" forum, you will surely receive help if you clearly formulate your question.

In the "other" forum, they will probably be happy to help if you ask your question precisely.Is it reasonable to roughly estimate about 10 units per month as a solid initial assumption? Or does it vary a lot? I probably won’t be able to reach anyone today.
The meter would be an additional cost on top of the basic price of the heat pump tariff, right?
