Ideal Heat Exchanger Assembly Super Plus 133188

The Ideal 133188 is a heat exchanger assembly supplied for the Ideal Commercial Super Plus range of boilers. It is the component that transfers heat from the combustion gases into the system water, so it sits at the centre of the appliance's heating circuit. The assembly is listed under part type HEAT EXCHANGERS and is used across the Super Plus and Module Super Plus DBI commercial models.

• Water weeping from the heat exchanger body or from the joints around it
• Pressure loss on the system that cannot be traced to any other component
• Overheat lockouts or repeated high-limit trips during normal running
• Combustion readings that drift outside the expected range, or visible sooting around the exchanger
• Reduced heating output on a boiler that is otherwise firing correctly

• Check the GC number and the appliance serial plate before ordering, as the Super Plus range uses more than one heat exchanger variant.
• Confirm the model against the compatibility list, including any DBI variant, as the assembly is shared across several commercial models.
• Have a replacement gasket or seal set to hand if the existing seals are disturbed during removal.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
