The gear in a hydronic heater forms part of the drive train that transfers rotational motion to key internal components such as the burner assembly or circulation pump. When this gear wears, chips, or fails, the driven component loses input power, which can cause erratic burner cycling, loss of fluid circulation, or a complete heater shutdown. Replacing a worn gear promptly with the correct OEM part restores proper drive engagement and ensures the heater maintains its rated heating output throughout the job.
