What it is
The INSULATION (HEAT EXCHANGER) is a Worcester Bosch component supplied under part number 8738903470. It is the insulating jacket that sits around the heat exchanger on Greenstar 1000 Series appliances, retaining heat within the exchanger and limiting heat loss into the surrounding casing and components. It is listed by the manufacturer against the Greenstar 1000 Series range.
Signs this part needs replacing
- Visible heat damage, scorching or crumbling of the insulation material
- Insulation detached or displaced from the heat exchanger
- Damp, saturated or degraded insulation found during service
- Overheating or heat spill into the appliance casing traced to missing insulation
- Insulation removed during a heat exchanger repair and not fit for refitting
Before you order
- Confirm the appliance model against the fit list above before ordering
- Check the part number 8738903470 matches the component being replaced
- Inspect the heat exchanger surround in situ to confirm the insulation is the failed item rather than the exchanger itself
- Confirm the appliance is isolated and safe to work on before dismantling
