how much power (heat) does your septic tank put out? the reason I ask is I am pouring my own septic tank, and building up the walls with cement block...
so I was thinking, would it be worth it to put Pex in the slab-bottom of the tank (almost 50 sq ft), then run this in a closed loop into the radiant floor system in the house.
Anyway, if it puts out 3 watts, and I might be able to capture 1 W, this would not be worth it, but if it were more like 100 x that much, I may consider...
