What it is

The Vaillant 0020136638 is a complete pump assembly manufactured by Vaillant for its ecoTEC VUW condensing range. It moves heated water from the appliance around the heating circuit and back to the heat exchanger, so it sits at the centre of the boiler's circulation path. This version is the complete assembly, covering the pump head and body as supplied for appliances built from 2012 onwards.

Signs this part needs replacing

  • Radiators stay cold or heat unevenly while the boiler is running
  • The pump becomes noisy, with whining, humming or grinding audible at the appliance
  • The boiler overheats or locks out shortly after firing
  • Circulation through the heating circuit drops noticeably
  • Water weeps from the pump body, head or connections

Before you order

  • Match the number 0020136638 against the label on the existing pump or the appliance data badge
  • Confirm the appliance model and serial number to verify the ecoTEC VUW condensing pro 28 variant and build period
  • Inspect the pump gaskets and seals when the old unit is removed and renew them if they are perished
  • Isolate the appliance, drain down and follow the manufacturer's fitting instructions before removing the pump
