How often should the settings for the High Limit Aquastat be checked?

The settings for the High Limit Aquastat should be checked annually to ensure safe and efficient operation of the heating system. Regular inspection is crucial because the Aquastat plays a key role in regulating the temperature of the hot water in a boiler or hydronic heating system. It prevents overheating by shutting down the burner if the water temperature exceeds a predetermined limit. An annual check allows for the necessary adjustments to be made, ensuring that the system is functioning within safe parameters and providing reliable heating without the risk of equipment failure or potential safety hazards. Regular maintenance also helps in identifying any wear or malfunction that could lead to inefficient operation or safety issues, thereby prolonging the lifespan of the equipment.
