How it Works
A. O. Smith gas water heaters heat water by burning either natural gas or LP (liquid propane). All models have a thermostat/gas control to set the desired temperature. When a hot water fixture is opened, hot water flows out of the water heating unit and through hot water lines in the home. Depending on the unit, the water is either pre-heated with heat exchangers inside of a water tank and heated to a set temperature so it’s ready for use or is heated quickly on demand with a tankless unit to save energy.
Whether using a gas tank or gas tankless water heater, exhaust gasses are created by the heating process. These exhaust gasses need to be vented to the outdoors, and different styles of gas heaters have different venting requirements. Learn about different vent configurations.
A plumbing contractor can assist you in choosing a water heater that fits your needs and the ventilation capabilities in your home. You can also use the A. O. Smith online XPERT™ Water Heater Selector to help determine which water heater is the best fit for your home.
Still Have Questions?
- Type of power in your home. Most homes can accommodate an electric water heater, but not all are hooked up to natural gas.
- Initial purchase price. Gas water heaters are usually more expensive than electric water heaters and require a bigger upfront investment because of gas pipe configuration and venting.
- Long-term operating costs. Natural gas is cheaper than electricity in many regions, costing you less over time. Both electric and gas water heaters come in energy-efficient models to help reduce monthly bills.
