We need to replace our hail damaged solar panels and need 4' x 8'. Does anyone have Vortex Solar Pool Heaters? http://shop.solardirect.com/index.php?cPath=21_34_38_48
I can't tell for sure, but I don't think they are the standard nipple header assembly most others are and the header is 2" instead of 1.5". We currently have the style with the bypass on one end which makes the water travel up one side and done the other. These will be in one end and out the other so I'm hoping for more water flow thus more heating. The only other ones I can find are 1 x 8 that come in sets of 4 you plumb together. Maybe easier to replace if one starts leaking, but I'm hoping the Vortex are beefy and last longer.
