A natural gas tankless water heater can offer energy- and money-saving benefits.
Here’s how it works. When you turn on the hot water tap, cold water is drawn through a pipe into the unit and heated by a gas burner. By only heating water when you need it, the need for a storage tank that constantly maintains hot water is eliminated. A tankless water heater uses 30-50 percent less energy than units with tanks, saving a typical family about $100 or more per year, depending on water usage.
A tankless water heater’s ability to offer a continuous supply of hot water makes it ideal for homes with a hot tub or whirlpool. Tankless units reduce the risk of leaks or water damage, and a typical model has an average life-expectancy of up to 20 years, compared to 8 to 10 years for tank type water heaters.
Right now Chattanooga Gas, along with select tankless water heater manufacturers, offers cash-back rebates when you switch from electric or propane to natural gas.
