Ideal Spacer Kit HIU Divert Valve 178080

The Ideal HIU spacer kit for the diverter valve is a service component supplied for the diverter valve assembly on Ideal heat interface units. It is listed by the manufacturer under part number 178080 and is held as a spare for the Ideal Commercial range.

The spacers locate with the diverter valve so the valve sits correctly within the unit, which is what allows the diverter to move cleanly between domestic hot water and heating duties. Where the original spacers are worn, distorted or missing after previous work, the valve can sit out of position and the changeover becomes unreliable.

• Domestic hot water runs cold or only warms intermittently while the heating side continues to work
• Tap temperature swings between hot and cold instead of holding steady
• The unit fails to change over cleanly between hot water and heating demand
• The diverter valve sticks, judders or makes noise during changeover
• Water weeps around the diverter valve area, or the valve body sits visibly out of line

• Confirm the part number 178080 against the unit data badge or the manufacturer's parts listing before ordering
• Check the appliance model against the compatibility list, as the same part number can be listed under more than one reference
• Note that 1782878 may appear on older documentation or stock records for the same item
• Inspect the diverter valve body and the surrounding components while the unit is open, so any further worn parts can be identified in the same visit
