What it is

The Ideal 181133 is a complete hydroblock kit for the Ideal Logic CODE Combi Esp1 38 combi boiler. The hydroblock is the water-side assembly that manages the flow of water through the boiler and the changeover between central heating and domestic hot water. This kit is supplied for the 38kW variant of the appliance.

Signs this part needs replacing

  • Water leaking from the hydroblock body or its seals
  • Boiler pressure dropping with no visible external leak
  • No hot water, no heating, or the boiler failing to switch between the two
  • Fault codes relating to the diverter valve or water flow
  • Restricted flow caused by scale or debris build-up

Before you order

  • Check the GC number on the boiler data badge against 47-349-37
  • Confirm the part number 181133 matches the number on the existing component or the manufacturer's parts list
  • Check that the boiler is the 38kW variant, as this kit is specific to that output
