In this active,closed-loop system,incoming potable water is routed to the solar storage tank,but never into the collectors.A water and antifreeze mixture circulates from the collectors through a coil of pipe in the solar tank,and then is pumped back through the collectors.The potable water is warmed by heat transfer through contact with the pipe.In most climates,s 50/50 propylene glycol and water mixture will keep collectors from freezing.These systems require an expansion tank and a few other auxiliary components for filling venting,and maintaining the system.A definite advantage to antifreeze systems in that the collector can be mounted anywhere.These systems are pretty much the only choice in very cold climates.When there is not enough for sun,an electrical or gas back element wil be automatically switched on by controller
