Water Heater Gas Vs Electric Efficiency

Electric water heaters require less space.

Water heater gas vs electric efficiency.

Electric water heaters particularly electric heat pump water heaters can have higher ef ratings than gas water heaters. Unlike electric heaters gas water heaters can be dangerous to operate in small spaces that allow gas to build up. 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. This is due to the way that the heaters operate.

Gas water heaters also have a much faster recovery rate which makes them a convenient option for larger families. Many energy efficient water heaters are gas powered. Comparatively energy efficient gas water heaters have an ef of 67 or higher while energy efficient electric water heaters have an ef of 2 00 or 2 20 depending on tank size. All this can offset the higher cost of electric power to some extent.

A gas or electric water heater s energy factor ef is a measurement that. While gas hot water heaters cost less to run due to the lower cost of natural gas electric heaters are actually more efficient. And they have no combustible byproducts. A gas heater must vent the spent gas which also takes some of the heat with it.

Electric water heaters tend to have at least 98 thermal efficiency many are 99 percent or more. 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. In comparison gas heaters usually have between 80 and 85 percent.
