A 50/50 propylene glycol and water mixture 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. These systems are pretty much the only choice in very cold climates. When there is not enough energy for sun, an electrical or gas back up element will be automatically switched on by controller.
