There are three safety devices in every storage tank heater. If all three safety devices are not well maintained or installed incorrectly, it may cause a water heater’s tank to rupture prematurely, or in the worst case scenario, the heater may explode. Explosions are caused by rising water temperature inside the tank to the point where the water comes close to boiling point and creates steam. If there is no outlet for the steam, the increased pressure could cause the hot water tank to explode.
This can be avoided with the proper installation and the use of a durable and reliable water heater.
