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.

In the end, it comes down to the total consumption. The difference between the heat pump electricity tariff and the standard tariff is around 8 cents.
The problem is that this varies greatly depending on the region. Where I live, the heat pump tariff is not cheaper than the standard tariff. Therefore, the total consumption is irrelevant.Similar topics
