Ideal Heat Exchanger Assembly Kit 80 176222

The Ideal 176222 is a heat exchanger assembly kit manufactured by Ideal Heating for its commercial gas appliance range. It is the component that transfers heat from the combustion process into the system water, making it central to the appliance's heating performance. This kit is the size 80 variant, matched to the larger commercial Evomax and Instinct Heat models.

• Reduced heating output or water that never reaches the set temperature despite the burner firing.
• Kettling, banging or rumbling noises from the appliance during heat-up.
• Water weeping from the heat exchanger body, its seals or connection points.
• Repeated overheat lockouts or high-limit trips as heat transfer falls away.
• Black or discoloured system water and sludge build-up around the exchanger.

• Confirm the appliance model and GC number against the compatibility list, as the size 80 kit is specific to these commercial units.
• Check the existing part number on the appliance against 176222 and the alternative number 1782264 before ordering.
• Inspect the seals and gaskets at the exchanger connections and order replacements if they are being disturbed.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
