Ensure the safe and efficient operation of your high-efficiency tankless water heater or combi-boiler with this genuine OEM Air Pressure Flow Sensor. This critical air proving switch monitors the airflow within the combustion chamber, verifying that the blower motor is providing adequate ventilation before the burner ignites. If your heating unit is experiencing venting errors, ignition failure, or frequent cycling, a faulty air pressure sensor is often the culprit. Designed to meet strict manufacturer standards, this sensor ensures optimal fuel-to-air ratios and prevents hazardous exhaust buildup. Suitable for a wide range of condensing and non-condensing heating systems, this replacement part is essential for maintaining the reliability, longevity, and safety of your residential or commercial hot water system.
