What it is

The Ideal Esprit 2 Flow Group Kit, part number 175407, is a hydraulic assembly used in Ideal's Esprit 2 and Isar HE family of domestic boilers. It sits within the boiler's water circuit and controls the movement of water between the heating side and the domestic hot water side, including the diverting function that switches the appliance between modes. The kit is supplied as a complete flow group assembly rather than as individual internal components.

Signs this part needs replacing

  • Domestic hot water runs cold or fails to reach temperature while the heating continues to work
  • The boiler does not switch cleanly between heating and hot water modes
  • Water weeping from the flow group body, its joints or its connections
  • Hot water temperature fluctuating or dropping away during a draw-off
  • The appliance remaining stuck in one mode, with the diverter failing to move

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the correct variant
  • Confirm the boiler model and output, as this kit covers several Esprit 2 and Isar HE versions
  • Inspect the seals and gaskets on removal and renew any that are perished before reassembly
  • Isolate and drain the appliance before starting the swap
