What it is
The Biasi BI1672100 is a complete circulating pump assembly used in Biasi gas boilers. It moves primary water around the heating circuit and through the heat exchanger, maintaining flow across the appliance's operating range. This listing covers the pump as a complete unit rather than individual pump components.
Signs this part needs replacing
- The boiler runs but the heating circuit stays cold or heats unevenly
- Pump makes grinding, humming or rattling noises during operation
- Flow and return temperature difference is excessive, pointing to poor circulation
- The pump body is seized or the shaft will not turn by hand
- Repeated overheat or flow-related lockouts on the appliance
Before you order
- Confirm the boiler model and GC number against the fitment list above
- Check the pump body and connections on the appliance match the part being replaced
- Verify the fault is with the pump itself and not the wiring, PCB or system blockage
- Have the system isolated and drained before fitting
