What it is

The Ideal 180825 is a complete hydroblock kit rated at 30kW and built around the Minebea variant of the assembly. It is the hydraulic unit that controls water movement through the boiler, bringing the diverter valve, pump housing and associated waterways together in one serviceable block. The kit is used across a range of Ideal combi and heat-only appliances.

Signs this part needs replacing

  • No hot water, or hot water only available while the central heating is running
  • The diverter valve failing to move between heating and hot water modes
  • Water weeping from the hydroblock body, its joints or its connections
  • System pressure dropping repeatedly and needing frequent topping up
  • Pump or flow faults traced back to the hydraulic block rather than the pump head alone

Before you order

  • Match the boiler model and GC number against the compatibility list before ordering, as the same kit covers several Ideal appliances.
  • Check the number on the existing component; 1783019 is an alternative number for this kit.
  • Inspect seals, O-rings and gaskets as the block is removed and renew any that are perished before refitting.
