retrofit coils

Hi all,

I currently have a 30 tube 300 litre solar water heater, with integrated horizontal tank. I want to put a coil into this and put mains pressure cold water in one end, and get lovely piping hot out of the other end. Does anyone have a supplier that does finned flexible 15mm (1/2") copper or stainless steel pipe that I can cut into my tank. It is in 3 internal sections, with a 15mm pipe between each, so seriously limits my original plan of using a Plate Heat Exchanger, as no matter what size I try, I cannot flow the store water fast enough to get a decent flow of mains hot to the taps.

TIA
