Hot Water
Principle is the same but it is true the BIGGEST cause of STEAM LOCOMOTIVE boiler explosions are LOW WATER. They will also explode if pressure gets too high which is the purpose of the safety Valve. Just a fact I was stating. Did not mean to cause confusion but it seems people were thinking the ONLY reason a steam locomotive can explode is low water and that is not true! Hence the comparison to a boiler in a house, factory or anywhere and a water heater.
