Is this made by Floatron?

I agree with Waterbear and am willing to put my money down that they are only relying on minimal chlorine residuals to maintain a pool.

Hey, I've got a heating system that is guaranteed to heat your pool for no additional cost, other than the product itself, and will last a lifetime! Exclusions include water imbalance, chemical attack, rodent damage, wind damage, UV damage, weather damage, accidential or intentional impacts, contact with anything other than water, incorrect installations, and repeated contact of Di-hydrogen Oxide. Send me $300.00 plus shipping. You provide your own, locally available High Grade mounting surface.
Now where did I see that picture of a 4' x 8' sheet of plywood with rolls of black irrigation tubing connected to it? hmmmm.....
