What it is
The Worcester Bosch 87186814620 is a heat exchanger assembly with a painted finish, used in Greenstar Danesmoor 25/32 ErP oil-fired boilers. It transfers heat from the combustion gases into the boiler water circuit. It is a service component intended for replacement when the existing heat exchanger is leaking, corroded or blocked.
Signs this part needs replacing
- Water or condensate weeping from the heat exchanger body or its joints
- Repeated pressure loss on the sealed system with no visible external leak
- Overheating, kettling or banging during firing
- Soot, scale or corrosion deposits restricting the flueways or waterways
- Boiler locking out or failing to reach temperature despite correct burner operation
Before you order
- Confirm the boiler model and variant against the manufacturer's parts list before ordering
- Check whether gaskets, seals or fixings are required separately for the swap
- Confirm the appliance is the ErP version, as fitment differs across Danesmoor ranges
- This is a specialist component — installation should be carried out by a competent heating engineer
