Not to be an *** but last I checked into this the cost wasn't worth it. It would take almost 10 years to pay itself off unless you got "funding" by the state, which a lot of states offer. Like a tax reduction is what I meant. A hot water heater is the cheapest thing you could have done and should still do. All you need is some copper pipes nice mat black paint and some plexi or even regular glass, and a pressure release valve. You would be suprised how hot that water can get. From what I gather thats like barely under the cost of A/C.
Hats off to ya anyway. I am all about screwing the electric company because they truley enjoy screwing me.
