What it is
The Biasi BI1782102 is a condensing heat exchanger used in Biasi Advance series gas boilers. It transfers heat from the combustion gases to the heating and domestic hot water circuits, and in condensing mode recovers latent heat from the flue gases. It is a serviceable component within the appliance's combustion and water circuit.
Signs this part needs replacing
- Water or condensate weeping from the heat exchanger body or its connections
- Visible corrosion, pitting or scale build-up on the exchanger surfaces
- Reduced heating or hot water output with the burner firing correctly
- Kettling, banging or unusual noise from the heat exchanger during operation
- Repeated lockouts or fault codes linked to the combustion or condensing circuit
Before you order
- Confirm your appliance model and GC number against the fit list above
- Check whether your boiler is the natural gas or LPG variant, as both are listed
- Verify the part number on the existing component before removal
- Check whether seals, gaskets or fixings are required separately for the installation
