Next to the heating and cooling system, the water heater is the largest energy user in your home. That's why nearly 9 out of 10 homeowners, who have a choice, choose natural gas water heaters. Depending on local rates, natural gas water heaters typically have an operating cost half that of other energy sources and can make more hot water faster than electric units. Most natural gas hot water tanks have an Average Appliance Life of 10-17 years.
Side venting units allow for installation in ordinarily hard to reach places.
One model can even be installed outdoors. Wall mounted units provide instantaneous hot water. Water is heated as it passes through the heating coil inside the unit on its way to the faucet. This means that the unit turns on as water is being drawn and shuts off when the faucet is turned off. Combination Space Water Heating Systems are available.
