Hello.
I am planning to install a Vaillant ground source heat pump VWF 88/4.
We are considering installing a second electricity meter to benefit from a cheaper tariff for the heat pump.
However, this meter would be off for up to 6 hours per day.
As far as I know, we do not have a buffer tank integrated.
Alternatively, we could use the regular electricity supply (one meter). Overall, this would cost about €250-300 per year more than with the heat pump tariff.
I am concerned that during the off periods, the electric heating element might turn on, and we could end up spending much more than the €250-300 savings.
How does the electric heating element usually work – does it only activate in emergencies, or does it always come on when hot water is drawn?
I would appreciate any answers or experiences.

I don’t think a second meter is worthwhile. I have one, and here locally the heat pump tariffs are actually somewhat cheaper than the regular rates, but it’s maybe around €80 (about $90) savings per year. Who knows if that will stay the same. The building is KfW 70 standard, with approximately 180m² (1940 sq ft) of heated space and 65m² (700 sq ft) of unheated area (basement) included within the insulated building envelope. Heating and hot water consumption with a ground source heat pump is under 2000 kWh.

18.99 cents? Where and which provider? And is that plus VAT or inclusive?Including VAT.
You should check Verivox.
There you can compare electricity prices specifically for heat pumps (the other major portal doesn’t offer a comparison for heat pump electricity).
The provider I use is the only one that doesn’t charge a basic fee (and also doesn’t offer additional discounts).
Currently, they even offer 18.81 cents for new customers (not for existing customers). Other providers, including discounts, have slightly lower prices.
