What it is
This is Worcester Bosch's painted heat exchanger, part number 87161078300, for the Heatslave HE 12/18 and HE 18/25 internal oil boiler range. It is the earlier version of the heat exchanger used on units built before factory date code FD782, and is the component that transfers heat from combustion into the boiler's water circuit.
Signs this part needs replacing
- Water or oil leaking from the heat exchanger body
- Kettling or banging noises from the boiler
- Reduced heat output or the boiler struggling to reach temperature
- Visible corrosion, pitting or soot build-up on the exchanger
- Boiler losing system pressure with no other identified leak
Before you order
- Check your boiler's factory date code (FD number) to confirm it is before FD782, as later units use a different heat exchanger
- Match this part number against your existing component before ordering
- Isolate the oil, electrical and water supply before removal
- Replacement should only be carried out by an OFTEC-registered oil heating engineer
