Kenmore gas powered water heaters offer faster water heating compared to electric water heaters. On average, heating water is twice as fast with a natural gas water heater, which is ideal for large families. Our natural gas heaters are available in a wide range of sizes and capacities, from 30 to 98 gallons. Keep your peace of mind knowing that if there's a blackout you'll still have access to hot water. Unlike electric heaters, a gas water heater is still operable during periods of no power.
