There's one method of using water to cool the roof/attic that can help. I use solar panels to heat my pool. The pool holds ~30,000 gallons. There are eight 4'x10' solar panels on the roof. Sunlight hitting them warms the pool -- not the attic. I've noticed a significant improvement in cool-down cycle (time it takes to get the house cool again after we've been away) with the pool heater running. Since the pool water is being circulated by the filtration pump during the day anyway, there's almost no *extra* cost to use the solar panels. -- Regards, Robert L Bass =============================> Bass Home Electronics 2291 Pine View Circle Sarasota � Florida � 34231 877-722-8900 Sales & Tech Support http://www.bassburglaralarms.com =============================>
