## Can a Gas Water Heater Explode?
Yes, a gas water heater can explode, but it’s a rare occurrence. According to the National Fire Protection Association (NFPA), there were an average of 1,550 home fires involving water heaters per year between 2012 and 2016. Of these fires, 12% were caused by gas water heaters.
## Causes of Gas Water Heater Explosions
There are a number of factors that can contribute to a gas water heater explosion, including:
Gas leaks: A gas leak can cause a build-up of gas in the water heater’s combustion chamber. If the gas ignites, it can cause an explosion.
Malfunctioning gas valve: A malfunctioning gas valve can allow too much gas to flow into the combustion chamber, which can also lead to an explosion.
Blocked flue: A blocked flue can prevent the exhaust gases from escaping the water heater, which can cause a build-up of pressure inside the tank. If the pressure becomes too great, the tank can rupture and explode.
Overheating: If the water heater is not properly maintained, it can overheat and cause the tank to rupture.
Improper installation: A gas water heater that is not properly installed can also be a hazard. If the water heater is not level, it can cause the gas to pool in the combustion chamber, which can lead to an explosion.
## Symptoms of a Gas Leak
If you suspect that there is a gas leak in your home, it is important to take immediate action. The following are some symptoms of a gas leak:
The smell of gas: Natural gas has a distinctive odor that is similar to rotten eggs. If you smell gas in your home, it is important to leave immediately and call 911.
Hissing sounds: A hissing sound can be a sign of a gas leak.
Dead plants: Gas leaks can cause plants to die.
Increased gas bills: A sudden increase in your gas bill can be a sign of a gas leak.
