Gas Boiler Not Heating Water? A NJ Tech Explains Why | Air

Sep 18, 2020 · This switch is located above the low limit safety and interrupts the burner in the case of low water and may allow the boiler to restart once the water level is restored. Low-mass water-tube boilers often also require a proof of water flow through the boilers. Because of their low-mass, overheating is nearly instantaneous if water flow is stopped.
