Solar Energy – Parts for solar thermal/hot water system (Enerworks)



This is part 2 of a tour with detailed explanation of a residential solar thermal/solar hot water heater system. Here I do into detail on various parts/components including the controller, temperature sensors, expansion tanks, flow meter, bypass valve assembly and stagnation control methods like vacation bypass valves, heat dump radiator, and covering the collector with a tarp. The system is the Enerworks one. It’s installed in Ottawa, Ontario, Canada, so cold climate issues apply. The solar panels or collectors are flat plate type. The solar tank and the natural gas backup tank are shown, as well as the heat exchanger and all piping. How the solar energy from the sun heats the absorber in the collector and then the food grade propylene glycol (antifreeze) and water mix is also covered.
