What happens when you add cold water to a hot boiler?
Thermal shock occurs when cold water enters a hot boiler. When a boiler is running at or near full power, it is full of boiling water, so the sudden introduction of cold water will cause a serious reaction with the hot water currently in the boiler. This potentially powerful reaction is called thermal shock.Why does my Steam Boiler lose water?
The main vents or radiator vents are losing water or steam. You can lose a lot of water through an air vent. … If the vent can’t close tightly because there’s dirt in its seat, lots of steam will escape. You’ll have make up that missing water at the boiler.
