Solar Domestic Hot Water (SDHW) works well in cold climates and can reduce water heating costs by 65% or greater. It provides a sensible, green solution to today’s soaring energy costs, and can produce significant dollar savings as the years go by.   The Closed-Loop Systems provide a unique solar hot water heating solution for both new and existing homes.  These fully self-contained units utilize non-toxic propylene glycol as a heat-transfer fluid; this liquid allows for reliable, freeze-proof operation even in the harsh winter months. The glycol circulates through the system via an almost silent circulator pump.
