What it is

The Worcester Bosch base insulation for the heat exchanger, version code ALO, is a replacement insulating component for the base of the heat exchanger. It is designed for use in Worcester Bosch oil boilers, including Danesmoor, Heatslave and Boilerhouse models. The insulation reduces heat loss from the heat exchanger base and helps maintain efficient combustion.

Signs this part needs replacing

  • Insulation becoming detached from the heat exchanger base
  • Increased heat loss or reduced boiler efficiency
  • Overheating or hot spots around the heat exchanger base
  • Corrosion or condensation on the heat exchanger due to failed insulation

Before you order

  • Check your boiler model against the fit list above
  • Confirm the heat exchanger version code is ALO
