What it is

The Worcester Bosch Type E-W flow regulator is a 12 litre restrictor supplied as a spare for Worcester Bosch gas boilers. It sits in the water circuit and controls the rate at which water passes through the appliance, keeping flow within the design limits of the heat exchanger and the domestic hot water side. This example is the red-bodied Type E-W variant, identified by Worcester Bosch part number 87161410610.

Signs this part needs replacing

  • Domestic hot water flow rate noticeably lower than the appliance's rated delivery
  • Flow rate that fluctuates or drops away as the tap or outlet is opened further
  • Scale, debris or sediment visible in or around the regulator body
  • Water weeping from the regulator or its connections
  • Boiler struggling to hold a steady flow during draw-off

Before you order

  • Check the appliance GC number and model against the compatibility list, as the same boiler family can use different flow restrictors.
  • Confirm the part number on the existing component matches 87161410610 before ordering.
  • Note the earlier number ZBUNC122, which may be marked on older stock or documentation.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
