Pool heater leakage

Pool water pipe going into Jandy LJ lite 2 heater froze. Made the mistake of turning on the heater. Made cranking noise with in seconds gave a profuse leak. The pool guy tells me that I need a new pool heater. I think heat exchange tube is busted. Do you have any repair suggestion.

    I have FAFCO solar collectors for my pool. It seems every spring there are 2-4 leaks that have developed. plugging seems to be inefficient as you then lose one more heating tube, is there a way to simply patch so you do not lose that tube?

Chances are that the header or manifold is cracked. usually the heat exchanger themselves are not damaged from freeze, but either the rear manifold (header) or the front header (the one that pipes go in and out of). Sometimes both. Replacing the entire heater is not necessary, about $200 in parts usually. We have a schematic diagram of the LJ heater here:
