What it is

The Ideal 178079 is a spacer kit for the modulating valve used on Ideal HIU (heat interface unit) appliances. It sits within the modulating valve assembly and holds the internal components at the correct spacing and alignment so the valve can regulate flow accurately. Ideal supplies it as a serviceable spare for Ideal Commercial equipment.

Signs this part needs replacing

  • The modulating valve will not hold a steady setting, giving fluctuating domestic hot water temperature
  • The valve sticks or binds when adjusted
  • Internal components sit misaligned, producing noise or vibration from the valve body
  • The existing spacer shows visible wear, compression or deformation
  • Repeat faults traced back to the modulating valve assembly

Before you order

  • Confirm your appliance model against the compatibility list below
  • Check the part number on the appliance before ordering
  • Cross-reference the alternative number 1782890 when checking older documentation
