What it is

The Baxi 7223450 is a hydraulic group assembly used in Baxi Main Eco System boilers. It forms the water-side section of the appliance, carrying the diverter valve and the associated hydraulic components that switch the boiler between domestic hot water and central heating operation. It is supplied as a complete assembly rather than as individual internal parts.

Signs this part needs replacing

  • No domestic hot water while the central heating continues to run normally
  • Radiators warming when only a hot water tap is open
  • Hot water running cold or cycling between hot and cold at the tap
  • Diverter valve failing to move, or the actuator running without changing the water path
  • Water weeping from the hydraulic block or from the joints around the assembly

Before you order

  • Confirm the appliance GC number against the compatibility list, as the same model name can appear with more than one GC number
  • Check the existing part number on the boiler before ordering, particularly if the appliance has been worked on previously
  • Note that 7216624 and 1132117 are also used to identify this assembly
  • Inspect the seals and gaskets on the existing hydraulic group before refitting, and renew any that are compressed or damaged
