What it is

The Biasi KI1042511 is a diverter valve body used in Biasi Acquapiu MFS combi boilers. It forms part of the 3-way Honeywell VCZZMG600E diverter valve group, directing water between the domestic hot water and central heating circuits. The body houses the internal ports and seals that switch flow according to demand.

Signs this part needs replacing

  • No hot water while the heating continues to run
  • Heating circuit warms up when a hot tap is opened
  • Domestic hot water runs lukewarm or fluctuates in temperature
  • Diverter valve sticking, causing intermittent hot water
  • Scale, debris or damage visible around the valve body ports

Before you order

  • Confirm your boiler is a Biasi Acquapiu 120 MFS or 124 MFS
  • Check the part number on the existing valve body matches KI1042511 or the superseded code KG1042511
  • Establish whether the fault lies with the valve body or the actuator head, as these are separate components
  • Inspect the valve group for scale or debris before fitting a new body
