What it is

The AUTOMATIC AIR VENT is a boiler component manufactured by Alpha, supplied under part number 1.015436. It releases trapped air from the heating circuit automatically, preventing air locks that would otherwise restrict circulation and cause noisy operation or poor heat distribution. It is intended for Alpha Commercial PRO TEC 50 series appliances.

Signs this part needs replacing

  • Water weeping or dripping from the vent body or cap
  • Persistent air in the system despite correct filling and venting, with gurgling or noisy circulation
  • Radiators or the boiler running hot at the top and cold lower down where air collects
  • The vent cap no longer seats correctly or the float mechanism has stopped releasing air

Before you order

  • Confirm the appliance model is an Alpha Commercial PRO TEC 50 or PRO TEC PLUS 50 LPG unit
  • Check the existing vent for the part number 1.015436 before ordering
  • Verify the fault is with the vent rather than with system pressure, as low pressure can mimic air-lock symptoms
