What it is
The Worcester Bosch 87161124330 is a secondary heat exchanger final assembly for the Worcester Greenstar Danesmoor HE oil-fired boiler range. It forms the secondary heat exchange stage of the appliance, where residual heat in the flue gases is transferred to the returning system water. This assembly is specified for appliances built after FD790.
Signs this part needs replacing
- Boiler efficiency has dropped, with higher fuel use for the same heat output
- Flue gas temperatures running higher than expected, indicating poor heat recovery
- Water weeping from the heat exchanger body or the surrounding casing
- Visible corrosion, scale or debris build-up across the exchanger surfaces
- Boiler locking out or failing to reach its set flow temperature
Before you order
- Confirm the boiler model matches the fitment listed above
- Check the appliance FD number is after FD790
- Establish that the fault lies with the secondary heat exchanger rather than the primary exchanger or another component
- Arrange fitting by a competent oil heating engineer
