What it is

The Worcester Bosch 87186841750 PHE to tank pipe (supplied as PIPE PHE TO TANK) is a water-carrying pipe that connects the plate heat exchanger to the tank on Worcester Greenstar Heatslave II and Heatslave II EXT oil-fired boilers. It forms part of the appliance's internal water circuit, carrying water between the plate heat exchanger and the tank assembly.

Signs this part needs replacing

  • Water weeping or dripping from the pipe or its connections
  • Visible corrosion, pitting or staining on the pipe
  • Scale or debris build-up restricting flow through the pipe
  • Pipe or union damage found during servicing

Before you order

  • Compare the part number 87186841750 with the pipe currently fitted
