Tank-Less Gas Water Heaterby GE

    Available in indoor or outdoor models, tank-less gas water heaters measure 23 inches high, 14 inches wide, and 10 inches deep, making them ideal for small spaces, such as attics and closets. Available in June, users can choose from two flow rates: a natural gas 7.5 gpm model or a 9.4 gpm unit available in natural gas or LP gas. By heating water only when needed, the tankless units maintain efficiency ratings of .82, compared with .53 to .62 for standard water heaters, and can save homeowners up to 25% on water-heating costs annually, the maker says. 800.626.2000 www.ge.com.
