We went to Teledyne Laars to bring you the latest advanced technology in pool heating. They created an exclusive copper finned heat exchanger that's 82% energy efficient, so as your pool temperature rises, so do your savings. Featuring stainless steel burners, porcelain-lined headers and a ceramic fiber combustion chamber, they're 30% lighter than other heaters so they're easier to install. These high-quality, weather-resistant heaters can't be affected by high winds or rain - even in coastal areas. So just dial up the heat when the weather cools down, slip in and say, Mmmm." Your swim season will be longer than ever! Warranted for 1 year.
