Complete thermostat assembly for the Hi-Flame Alpha 3 Boiler (AL910), including both the thermostat body and the plastic control knob. The thermostat regulates the rear air inlet based on boiler water temperature, automatically reducing the burn rate as the water heats up. A faulty thermostat disrupts this control, leading to inconsistent output or overfiring.

✅ Compatible with: Hi-Flame Alpha 3 Boiler (AL910)

🔧 Specifications

  • Contents: Thermostat body and control knob
  • Material: Mixed (metal body, plastic knob)
  • Part type: Boiler thermostat assembly (complete)

The boiler thermostat is a core control component on the Alpha 3 Boiler, keeping the heating output matched to the system demand and preventing the water from overheating. Replacing the complete unit rather than individual components ensures a correct calibration and a straightforward installation.
