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

At the time, we insisted on installing only one meter and running the air-to-water heat pump on the main house electricity supply.
A second meter wouldn't have been cost-effective anyway because of the basic connection fee.
Since the photovoltaic system was already planned back then, we wanted to stick with just one meter.
Now, the photovoltaic system has been in operation for a year, and our total electricity costs over the past year were 240€ (about $260).
With 20€ (about $22) per month for house electricity and heating, we are very satisfied 😀

P.S. The heating works well with the loops (which were not installed so closely together everywhere). The screed has now been dried using the heating.

That sounds solid. How long did it take to recoup the investment costs of the photovoltaic system?

We currently expect the costs to be amortized after about 10 years. If electricity prices continue to rise, this will likely happen sooner.

I have now tried to do some calculations and so on. If I also run the heat pump through the household meter, I would be about €400 (approximately $440) more expensive per year without photovoltaic systems. There is a 12 cent/kWh difference in the tariffs. Therefore, I think it makes sense to start with two meters and photovoltaic to see how things develop. Currently, I am still with the local supplier. Is it possible to switch providers differently in this case? For example, to get household electricity from somewhere else and keep the heat pump electricity with the local supplier? Who would pay the feed-in tariff in this case?

The solar installer said that photovoltaic electricity could also be used for both meters. This would be called a power-to-heat system. So, as already mentioned here, this would work with a small additional effort from the electrician.

That’s quite a lot. What kind of rate do you have for your regular household electricity? Maybe it would make sense to switch providers in that case.

The feed-in tariff is always paid by the grid operator, so it has nothing to do with your electricity supplier.
