What it is
This is a Worcester Bosch heat exchanger, the component that transfers heat from the burner's combustion gases into the water circulating around the heating system. It sits at the core of the appliance's hydraulic circuit and is used across the Greenstar Ri and i System ranges. Over time the internal waterways can scale or sludge up, and the gas-side surfaces can corrode, which is when replacement becomes necessary.
Signs this part needs replacing
- Kettling, banging or rumbling noises from the boiler during firing
- Reduced heating or hot water output despite the burner running correctly
- Overheat lockouts or repeated high-limit trips
- Visible leakage or weeping from the heat exchanger body or its connections
- Discoloured or restricted waterways found during a strip-down
Before you order
- Check the GC number and appliance serial plate to confirm the correct variant for your boiler
- Cross-check the previous part numbers 87161070540 and 87161070550 against the unit being removed
- Confirm whether a gasket or seal kit is needed for the specific appliance before fitting
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
