Gas Vs Electric Hot Water Heater Efficiency

Similarly electric heaters can have higher energy factor ratings than gas heaters.

Gas vs electric hot water heater efficiency.

The bigger the ef number the more efficient the appliance. And they have no combustible byproducts. Unlike electric heaters gas water heaters can be dangerous to operate in small spaces that allow gas to build up. Standard gas water heaters have an ef of about 50 to 60.

Gas water heaters are less energy efficient than electric heaters but the cost of electricity itself makes the running costs of an electric heater higher. A gas water heater uses the heat from burning a fuel usually natural gas to heat water while an electric water heater uses electric resistance coils. A gas or electric water heater s energy factor ef is a measurement that. All this can offset the higher cost of electric power to some extent.

A gas heater must vent the spent gas which also takes some of the heat with it. On the other hand. Electric water heaters particularly electric heat pump water heaters can have higher ef ratings than gas water heaters. Electric water heaters tend to have at least 98 thermal efficiency many are 99 percent or more.

Department of energy to help consumers compare the efficiency of similar appliances. This is due to the way that the heaters operate. Electric water heaters are not only efficient but also don t have any fuel that could leak or explode. In comparison gas heaters usually have between 80 and 85 percent.

You ll find both gas and electric models.
