FULL AUTOMATIC OPERATION: Is achieved with the optional LX220 control. When the attic is eight degrees hotter than the pool and the pool needs heat, the LX220 automatically routes water up to the PCS1 and turns it on. It can even synchronize the pool's pump by turning it on at the same time. Temperature sensors sense the pool and attic temperatures. Maximum heat is then extracted automatically. The pool owner simply sets the desired thermostat setting on the LX220. FlowreversalTM can substantially reduce the pool's heat demand by allowing the heat to rise from the main drain. FlowreversalTM was a trademark of Mark Urban, Tustin, California who passed away in 2010. His Flowreversal valves are no longer available, but the Palmer Flowreversal Solution at the link below will replace Mark's valves. A, eBook is available to teach you how to implement Flowreversal in your pool. Or, if desired, a complete module kit of valves is also available at this site.
A pool blanket can be used when the pool is not in use thereby minimizing heat losses caused by evaporation (60%). Specifications are subject to change without notice. © 1990-2016 All rights reserved by Northern Geo LLC of Appleton MN 56208.
THE REAL DEAL: This is the original Green Machine Solar Pool Heater as invented and patented by Edward G. Palmer, the founder of SolarAttic. When you buy from SolarAttic, you are purchasing solar energy technology as originally created by the inventor and designer of this next generation solar pool heater technology.
