What it is
The Biasi BI1901104 is a high head pump for Biasi gas boilers. It circulates water through the heating circuit, maintaining the flow and pressure required by the appliance. This pump supersedes the earlier code BI2901102.
Signs this part needs replacing
- No heating or hot water, with the boiler firing but not circulating
- Pump running noisily or vibrating
- Boiler overheating, locking out or cycling on the overheat thermostat
- Pump not running at all when the boiler calls for heat
- Water leaking from the pump body or connections
Before you order
- Check your boiler model and GC number against the Fits list.
- Confirm the part number on the existing pump, or the superseded code BI2901102.
- Make sure the fault is with the pump and not another component in the heating circuit.
