Do safe temperatures play a part in water heater safety? You had better believe it, and if you don’t all you need to do is check out the exploding water heater video from MythBusters. Actually, that explosion was the result of an over-pressurized water heating unit. However, temperatures that exceed 212 degrees can result in pressure levels that can result in an explosion.
Of course water heater temperatures can get too hot without resulting in an explosion. Your water heater shouldn’t be turned up above 180 degrees, and anything over 120 degrees can burn people depending on the length of exposure.
The most important thing to remember about safe temperatures or pressure levels when dealing with your water heater is to call a trained water heater technician if and when you experience maintenance issues. It may look like a simple unit, but modern water heaters are computerized and sensitive and require the attention of someone who knows what they are doing!
