Can a water heater burst?

Unfortunately, yes, a water heater can burst or explode, regardless of whether your water heater is gas or electric. This happens when the temperature is set too high or when the pressure relief valve of a water heater malfunctions. As water heats up, it can turn into steam, creating pressure that is typically relieved through a pressure relief valve. If the pressure relief valve is blocked or otherwise malfunctions, pressure will build up in your water heater tank and may cause it to explode. The damage a burst water heater tank can cause is significant -- similar to a rocket, the pressure causes the burst tank to shoot upwards through the ceiling. Therefore, a burst water heater can be very dangerous. We recommend checking your water heater's pressure relief valve to make sure it is in good working order. If you have any concerns about whether your water heater is functioning properly, you should have a professional come to your home and inspect it. POP! The same goes for water heaters. If the pressure builds up in the tank, it will eventually filter out and explode. Also, if the TP valve will disable the leak (which eventually goes), then the pressure continues to build up in the tank, which will lead to an explosion or explosion.
