In this case, the heat pump is operated using two electricity tariffs (two consumption meters).
A continuous power supply ensures the operation of the auxiliary consumers (circulation pumps, controls, etc.) via a separate
electricity meter.
The power from the additional, blockable power supply for the compressor and the internal electric back-up heater is sup-
plied via a second electricity meter and can be suspended by the power supply network operator at peak times. The duration
and frequency of the outage is determined by the power supply network operator or must be clarified with them.
