Labor-saving solar collectors
May 31, 2012

Caleffi’s StarMax V solar water heating collector is ideal for pumped glycol and drainback systems. The patent-pending design is similar to a standard four-outlet collector, but features a fifth outlet located at the bottom center and sloped internal upper and lower headers. When used in a drainback installation, the combination allows all fluid to drain without the need to pitch the collectors. www.caleffi.us
