Our 2 Panel EZ Connect Kit allows you to install your 2 panel solar water heater system in record time. As with all our systems they connect directly to your existing water heater and don't interfere with existing source of heat (gas or electric). This way you can enjoy hot water even during long cloudy periods. Based on our revolutionary EZ-Connect Solar Water Heater panels, with PUSH-FIT fittings, you simply plug the panels into each other. No more external connection pipes for multi panel installations! You don't even need a wrench for assembling the panel array. 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!
