ᐅ Is a Separate Meter and Electricity Tariff for an Air-to-Water Heat Pump Beneficial?

Does the electricity for the heat pump also come from the hamster wheel? 😉

2009. No, the granny pedals like crazy in the basement. But much less in summer, since only hot water is produced then.

We simply had a separate submeter installed for the heat pump. In our case, getting a separate meter from the energy supplier wouldn’t have been worthwhile, as the kilowatt-hour price for heat pump electricity is almost the same as for household electricity in our region.

It is important to note that some providers exclude heat pumps from household electricity, which could theoretically mean violating the terms and conditions.

Interesting topic, and I also have a question. We have two meters. (We weren’t asked, it was just done.)
I have now ordered the photovoltaic system, which should arrive next week. If I understand correctly, the photovoltaic system will then produce electricity only for the household power, not for the heat pump? Am I understanding this right? If so, I wouldn’t really benefit much from it?!

Many utility providers offer solutions to supply both the heat pump and regular household electricity simultaneously. You can look into corresponding metering concepts. However, this usually involves increased technical complexity and requires three meters instead of two.
Alternatively, you can have the heat pump connected to the regular household electricity supply and have the second meter removed. This will automatically end your heat pump electricity tariff. The advantage is a better self-consumption balance, and depending on your tariff, there may be no disadvantage since the heat pump electricity tariff plus meter costs are often not economical.

Ok. Then I understand. That would obviously be the most practical solution to increase the self-consumption rate. Especially after hearing that a potential electric car is not allowed to be connected through the heat pump meter.

Otherwise, you simply switch the heat pump to the regular electricity supply and remove the second meter. This also automatically ends your heat pump electricity tariff. This has the advantage of a better self-consumption balance and, depending on the tariff, usually no disadvantage, since heat pump electricity plus the meter costs are often not cost-effective.

If he is not aware of this, then he probably won’t have a metering setup to use photovoltaic electricity for the heat pump.

The question is also whether there is actually a specific heat pump tariff, or if there are just two meters because no bidirectional meter is installed at all?!
