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. 
1).Simple Installation, no maintenance, effective operation 
2).Easy retrofitting to existing systems 
3).Suitable for single and multiple solar heating application systems 
4).Preferred option for extremely cold areas and questionable water quality 
5).Incoming potable water is routed to the solar storage tank 
6).Porcelain enamel or SUS316 stainless steel storage tank with electrical or gas back up 
7).Double-walled copper coil heat exchangers in storage tank prevent contamination of household water
