Difference between gas and electric water heater. Electric heaters are cost effective than the gas water heater. 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. Gas heaters use energy from burning natural gas to heat water whereas an electric heater uses a coiled electrical element. A key factor is also the recovery rate which determines how quickly a tank can refill with hot water.

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 or electric water heater s energy factor ef is a measurement that. The cost of running each type depends on the cost of natural gas and electricity in your area. An electric heater uses nearly all the energy it receives converting it into hot water so you have less waste.

Tankless gas water heaters that use natural gas are much lower in price than electricity and propane water heaters. It must be noted that natural gas is not available in rural areas in this case propane is a better choice. A gas heater must vent the spent gas which also takes some of the heat with it. Electric water heaters particularly electric heat pump water heaters can have higher ef ratings than gas water heaters.
