What it is

The Worcester Bosch 87183103080 is a three-way valve with 22mm compression ring connections. It is used on Greensource air/water heat pumps to divert water flow between the heating circuit and the hot water cylinder. The valve is operated by the appliance control system to switch between space heating and domestic hot water production.

Signs this part needs replacing

  • Heating runs but no hot water, or hot water runs but no heating
  • Valve fails to switch between heating and hot water modes
  • Actuator motor runs but the valve spindle does not move
  • Water weeping from the valve body or compression joints
  • Stiff or seized spindle preventing full travel

Before you order

  • Confirm your appliance model is one of the Greensource units listed above
  • Check the pipework is 22mm and that compression ring connections suit the installation
  • Establish whether the fault lies with the valve body or the actuator head before ordering
  • Isolate and drain the system before fitting
