Using solar to heat my pool
I've got a 21' above ground pool and I'm thinking of trying to heat the water to lengthen the swimming season by using the sun. The hoses going to and from my pool are 1 1/2" dia. I'm thinking using 4 lengths of used hot water baseboard. The reason I'm going with 4 is that the area of four 3/4" baseboard pipes is the same as the area of my pump hoses. This way it shouldn't put any strain on my pump. I would build a manifold with a 1 1/2' inlet and reduced down to four 3/4" outlets and then feeding all four baseboards at the same time with another manifold at the other end of the heaters to go to the pool . Has anyone ever tried this. Should I paint all the fins a flat black? What else could I do to make it more efficient. Thanks ahead of time.
