For Natural Gas Customers
High efficiency natural gas water heaters use 10 to 50% less energy than standard models. Actual energy savings from high efficiency water heaters depend on size, heater location, and the size and placement of water pipes.
High-efficiency gas storage water heaters employ the same technologies as standard gas storage water heaters: a glass-lined steel tank is heated by a burner located at the bottom of the tank. ENERGY STAR® certified models increase efficiency by incorporating better insulation, heat traps, and more efficient natural gas burners.
