What it is
The Biasi BI1161100 is a domestic hot water (DHW) heat exchanger for Biasi gas boilers. It transfers heat from the boiler's primary circuit to the domestic hot water supply. It is used across the RIVA and Garda appliance families.
Signs this part needs replacing
- Reduced or inconsistent domestic hot water temperature
- Hot water flow rate that has dropped over time, often from scale build-up
- Water leaking from the heat exchanger body or its connections
- Discoloured or contaminated domestic hot water
- Boiler failing to deliver hot water on demand or locking out
Before you order
- Confirm your boiler model and GC number against the fitment list above.
- Check the part number on the existing component or in the manufacturer's parts list.
- Confirm the fault lies with the DHW heat exchanger rather than the primary heat exchanger or diverter valve.
- Check for scale or debris in the domestic water circuit that may have caused the failure.
