Our 3 Panel GS Kit allows you to install your solar water heater system in record time.  The GS System uses a “Solar Sidewinder” heat exchanger by Spectrum Solar. The Solar Sidewinder replaces one of the electric heating elements in your water heater and circulates a special food grade solar heat transfer fluid (DOWFROST) through the panels instead of water. Using our revolutionary EZ-Connect  Solar Water Heater panels you can simply thread the panels together. No more external connection pipes for multi panel installations! Each panel weighs slightly over 12 lbs. and is 24″ by 24″ but can still provide you with ample hot water. As with all of our Heliatos Solar Water Heating Kits you can begin your system with a few panels and  add more if you need more.  With this kit you DO NOT have to solder at all!
