What it is

The Ideal 175608 is a complete hydroblock kit rated for 24kW appliances. The hydroblock is the hydraulic assembly that houses the diverter valve and associated waterways, switching the boiler between domestic hot water and central heating operation. It is supplied by Ideal for its combi boiler range and is fitted as a single serviceable unit.

Signs this part needs replacing

  • No hot water or intermittent hot water while the heating continues to run
  • The boiler fails to switch between domestic hot water and central heating modes
  • Water weeping or visible staining around the hydroblock body or its connections
  • Hot water temperature fluctuating or running cold during a draw-off
  • Scale, corrosion or stiff operation of the diverter mechanism on inspection

Before you order

  • Check the GC number and model variant on the appliance data badge to confirm the 24kW version before ordering.
  • Confirm the appliance model against the compatibility list, as the same boiler family is produced in several output ratings.
  • A gasket or seal kit may be needed when refitting the hydroblock; inspect the existing seals during removal.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
