What is a Gas Water Heater

Gas water heater

A gas water heater is an appliance that utilizes gas or propane to heat water. Gas water heaters can be used for both residential and commercial purposes. The water is stored in a tank, typically a metal tank with a glass liner. The temperature of the water can be set by thermostats integrated into the appliances gas valve. When hot water is needed, it is drawn from the top of the tank and replenished with cold water to the bottom by means of a diptube. The cold water is then heated by a gas-fired burner located at the base of the tank. Gas water heaters are typically more expensive to install than electric water heaters but may have lower operating costs due to the cost of electricity.

Gas water heaters are available in a variety of styles…

  • Conventional Vent
  • Power Vent
  • Power Direct Vent
  • Direct Vent
  • Tankless
  • High Efficient

Gas water heaters typically last 8-12 years before requiring replacement. However, most manufacturers offer a 6 year warranty. This is important as some insurance companies will not cover you if you water heater causes any damage to your home or property if it’s out of warranty.
