What you get from FAST of Florida:
Yes, a water heater can indeed explode. Anything that causes excess pressure on your water heating system, such as a poor anode rod or a lot of sediment buildup, could potentially cause a water heater explosion.
The most common problem with water heaters is typically that the water tank produces too little hot water. Usually this can be solved by turning up the temperature on the tank’s thermostat. Be careful, however, not to turn the temperature up too high, as this can produce scalding hot water.
On average, replacing a gas or electric water heater with a similar model takes around two to three hours. The process usually takes between 45 to 60 minutes to drain, disconnect, and remove your old water heater.
If you are unsure whether it’s time to replace your water heater, there are a few main points to keep in mind when deciding whether or not it is time to install a brand new water heater:
