A gas water heater uses the heat from burning a fuel (usually natural gas) to heat 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.Gas water heaters also have a much faster recovery rate, which makes them a convenient option for larger families.

Reducing Energy Use:

Water heating accounts for about 18%of your home's energy use. Reducing your hot water use, employing energy-saving strategies, and choosing an energy efficient water heater with Low-flow fixtures for your home pool can help you reduce your monthly water heating bills.
