Pretty good item Review by Pool girl
The water really gets hot when it sits in the tubes but is average after it passes through. Instructions for assembly is great but does not indicate if there is anything else to do for instance, stop and start or just leave the water go through. I just can't imagine the tubes keeping warm when the water is cold. The water does come out mediocre.
