Here's another question....I'm looking at some on ebay, and they're cheap enough that I could buy 2 4x20 panels for just a little more than 2 2x20 panels through a retailer. I'm thinking that might be beneficial for getting a jump start on spring and extending the season a little longer into the fall....

Do any of you guys remove your heaters in the middle of the summer? I was thinking that if I bought two systems, I could pull one out and only use it for the spring and fall, and disconnect it and store it through the summer.

Anyone got any input on that idea?
