FAQ

What does flammable vapor sensor lockout mean?

FV Sensors are safety devices found on some water heater types that produce a soft lockout (a.k.a. the unit shutting off) when flammable vapors are detected near the unit, preventing them from igniting.

Should I turn off my hot water heater when I go on vacation?

While it’s not a good idea to turn off a water heater altogether, putting it in vacation mode can save you a lot of energy and money while you’re away.

How do I set my hot water heater to vacation mode?

If your hot water heater doesn’t have a vacation option, drop the temperature to 50 degrees Fahrenheit, or the lowest setting your thermostat permits, to simulate Vacation Mode. You can also choose to turn off your hot water heater.

Can a water heater explode?

It is a possibility. The temperature of the water inside the tank could rise to the point where it produces steam if the heating element and/or thermostat fail. If the situation worsens and there is no way to release the steam, the hot water tank may explode due to the rising pressure.

How many years does a water heater last?

It would be wonderful to know when it’s time to replace your water heater before it bursts and produces a mess or, worse, damage to your home. A household hot water heater typically lasts 6 to 13 years. You’re on borrowed time after 12 years!
