Abstract: An energy saving apparatus is described. The energy saving apparatus is attached to a standard gas-powered water heater. All gas-powered water heaters typically have an air vent which vents hot air from the water heater. The apparatus takes advantage of this fact by routing a cold water inlet line into a heating coil wrapped around the air vent, with the heating coil eventually being connected to an outlet water line that then enters the hot water heater. The heating coil is merely a water line located in between the cold water inlet line and the outlet water line that is wrapped around the air vent many times. The heat from the air vent will transfer some of its heat to the water circulating within the heating coil, causing the hot water heater to utilize this otherwise wasted energy and subsequently causing the hot water heater to need less energy to heat the water within the hot water heater.
