Is my water heater electric or gas?

It is always an excellent idea to check the electric panel to determine if your water heater is electric or gas. Look at each circuit breaker and find the breaker marked ‘water heater.’ If you cannot find such a label, you might want to turn off all circuit breakers in the panel. Next, look at your water heater if it is turned off, too.

Are electric water heaters more energy efficient than gas heaters?

Electric water heaters (particularly electric heat pump water heaters) can have higher EF ratings than gas water heaters. A gas or electric water heater’s energy factor (EF) is a measurement that compares the amount of hot water the heater produces per day to the amount of fuel it consumes.

How much power does a water heater use?

Electric water heaters range in power input from about 1,440 to 5,500 watts, and the same principle applies—the higher the wattage, the more quickly the unit will heat water. Gas water heaters tend to have higher initial costs than comparable electric water heaters but can also cost less to operate.

How does a gas water heater work?

It might have the same design as an electric water heater, but gas-powered units have a vent or chimney for conveying exhaust gas into the outside environment. We know gas water heaters use fuel combustion to operate the burners and heat the water. Unlike electricity, the thermal process releases potentially noxious chemicals into the air.
