What does a boiler interlock do?

A boiler interlock is a safety feature designed to prevent the boiler from operating under unsafe conditions. It ensures that the boiler only fires when certain parameters, such as water temperature, pressure levels, and flow rates, are within acceptable limits. This mechanism helps prevent overheating, pressure build-up, and potential system failures, enhancing overall safety and efficiency. Additionally, it may integrate with controls to ensure proper operation in conjunction with heating systems.
