Can a Tankless Water Heater Explode

We have some good news: tankless water heaters don’t burst. There is no tank, so there’s no need to worry about pressure buildup. Because tankless water heaters tend to be gas-powered, there is technically a risk of a carbon monoxide leak, but this is easily avoided so long as you schedule regular maintenance.

Is a tankless water heater a fire hazard?

Tankless water heaters can catch fire, however, the risk is minimal. Tankless water heaters only ignite and heat water on demand. Fire risk with tankless water heaters is largely caused by gas leaks that develop. Electrical sparks near gas leaks could cause fire or explosion.

Why do tankless water heaters burst?

In general, the basic reason why hot water heaters burst is that there is corrosion within the tank, which can lead to the tank bursting at its seams.
