Solar Thermal

Sick of high energy bills, our columnist investigates solar options from the WSJ. Great diagram and explanation of how a Solar Thermal system works. I was surprised by the cost and adding the water/glycol mixture. In areas that freeze, this does make sense. I am not sure about Southern California. The water heater makes sense with the extra cost having a tankless, but the picture here shows one with a tank. Not how the rebates end in 2008.
