What it is

The Vaillant 0020025744 is an inrush current limiter for ground source heat pump installations, identified in the manufacturer's naming as the VWZ 30/2 SV component. It limits the current surge drawn when a heat pump compressor or associated motor starts, protecting the electrical supply and downstream control gear from repeated high inrush peaks. The device is supplied as a standalone electrical component for service and repair work on compatible Vaillant GSHP systems.

Before you order

  • Confirm the part number 0020025744 matches the component removed from the appliance or the number listed in the manufacturer's literature for the installation.
  • Check the VWZ 30/2 SV designation against the heat pump or control assembly being worked on before ordering.
  • Verify the fault diagnosis points to the inrush current limiter rather than the supply, contactor or compressor circuit.
  • Refer to the manufacturer's technical documentation for the correct fitting and electrical safety procedure.
