Mar 13, 2012 · Most solar water heaters include flat-plate collectors through which water or a water-glycol mixture is circulated. "Closed-loop" systems have the collector filled all the time, and a pump circulates the fluid from the collectors, where solar heat is absorbed, to the tank, where a heat-exchanger coil transfers that heat to the stored water.
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil.The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation
