What it is

The Ideal 177261 is a complete hydroblock kit for Ideal and Morco appliances. The hydroblock houses the diverter valve and hydraulic components that direct water between the domestic hot water circuit and the heating circuit. It is supplied as a complete assembly rather than as separate internal parts.

Signs this part needs replacing

  • No hot water, or hot water running cold while the heating continues to work
  • Domestic hot water temperature fluctuating between hot and cold
  • Diverter valve failing to switch between heating and hot water demand
  • Water weeping from the hydroblock body or its seals
  • Boiler locking out or displaying a fault when hot water is drawn

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering
  • Cross-reference the alternative part number 1783010 when checking the existing component
  • Check whether the seals and gaskets around the hydroblock need replacing at the same time
