Residential Gas Water Heaters

Gas water heaters use combustion to generate heat, heating water faster than electric models. They boast a higher recovery rate, replenishing the water supply in a tank more quickly compared to a similarly sized electric water heater. Natural gas may also be cheaper than electricity in some areas of the United States, translating into lower monthly operating costs.

Gas water heaters burn natural gas or liquid propane and must be vented outdoors to safely release combustion fumes. Several venting options are available, depending on the model of the water heater, the space you're installing it in and the configuration of your home. With atmospheric ventilation, combustion gasses rise through an exhaust pipe to a flue on the roof. Direct vent water heaters use side wall vents, drawing air in for combustion and venting fumes outside. Gas water heaters with power ventilation connect to an exterior wall with horizontal or vertical piping, blowing exhaust outside using an electric fan. Learn more about venting configurations.

Water heaters in the late stages of life can show signs of reduced performance. Water heaters can also become less efficient, taking longer to heat water or delivering water that isn't as hot as usual. Some of these issues can be fixed, but it may be more cost-effective to replace an aging water heater that's continually having problems and ensure it doesn't suddenly stop working.

Our traditional gas tank water heaters have limited warranties that range between 6-10 years, while tankless gas water heaters come with 15-year limited warranties. A water heater's lifespan depends on how often you use it, the quality of the groundwater and how regularly you service and maintain the water heater. State's line of gas water heaters comes with limited warranties to protect your purchase.
