What it is
The Biasi BI1193110 is a combustion chamber overheat thermostat for Biasi Riva Plus HE boilers. It monitors temperature at the combustion chamber and interrupts the boiler's operation if that temperature rises beyond the safe limit. It is a safety-critical control on the appliance.
Signs this part needs replacing
- The boiler locks out or shuts down during a demand for heat or hot water
- The overheat thermostat trips repeatedly, including after the boiler has cooled
- The boiler runs briefly and then cuts out before reaching set temperature
- The thermostat shows signs of heat damage, corrosion or a loose or broken connection
- Fault-finding points to the overheat circuit rather than the primary temperature sensor
Before you order
- Confirm your appliance model and GC number against the fitment list above
- Check the part number on the existing thermostat before removal
- Confirm whether your boiler is natural gas or LPG, as the model variants differ
- If your model is not listed, check it against the manufacturer's parts list
