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

I will definitely pay an extra fee for the heat pump.

It should also be noted that some operators simply disconnect the heat pump electricity for 1-2 hours a day, usually around midday. That’s why we have the heat pump set up with time-of-use rates (peak/off-peak) from the local utility. I change households every 2-3 years.
In 2009, the off-peak rate was 9 cents per kWh (net).

An interesting option for optimizing electricity costs is a spot tariff. The electricity price in Leipzig fluctuates significantly throughout the day. These fluctuations are passed on to the customer. For example, electricity is quite expensive around 7:00 PM and very cheap at 5:00 AM. With the right habits, considerable savings can be achieved.

Briefly on the topic of photovoltaic systems and heat pump tariffs: Yes, it is possible. The key term here is cascade metering, and any solar technician can install it this way (without an additional meter). This allows the photovoltaic electricity to be used for both the household and the heat pump while still keeping the billing separate. It only requires about half an hour of extra work for the electrician.

BUT: many heat pump tariffs become less profitable with this setup, so it’s advisable to recalculate beforehand. If it was only just cost-effective before, the second meter can be removed. If it was a few hundred euros per year cheaper before (with high consumption and/or very low-cost heat pump electricity), then it should be left in place.

We also have an air-to-water heat pump and use two meters for peak and off-peak rates (main tariff) + (night tariff). The costs with our provider are around 22 cents per kWh. The peak and off-peak rates are almost the same, plus a basic fee of about 8 euros per month. We have a 120 sqm (1292 sq ft) house with an annual consumption of about 4000 kWh, which comes to around 75-80 euros per month.

P.S. We also have a third meter for household electricity, where the price is about 30 cents per kWh, plus a 12 euro monthly base fee.

That is exactly the right decision. Check how much the heat pump consumes during heating operation without a separate tariff/meter. Optimize the heat pump in the second year, and by the third year, you can calculate based on consumption and experience whether a separate tariff/meter is worthwhile.

I’m just wondering how I can then see how much the heat pump has consumed. I couldn’t find anything about this in the menu.
