A natural gas water heater's burner is sized to completely recover in about one hour, regardless of the tank size.
Whether you’re most motivated by budget or environmental impact, gas water heaters are a win-win purchase.

The best way to reduce energy use for water heating is to use less hot water.
Natural gas water heaters are a safe way to heat your household water. As with all home appliances, follow the manufacturer’s guidelines and code requirements.
NOTE: Manufacturers adopted a technology standard for 30- to 50-gallon water heaters that helps prevent flammable liquids from igniting. Since older water heaters are not equipped with this resistant technology, they are more susceptible to flammable vapors. To minimize the risk of accidents, elevate the water heater at least eighteen inches above the floor. Keep all flammable products in tightly closed, approved containers, stored far away from all appliances and out of the reach of children.
Turn your water heater to 120 F to save energy and avoid scalding.
