I had limited success with the tube & shell That's why I turned to a brazed plate for the price I could not go that route. Memphis is right the refrigerant needs to flow around the outside of the water tube. There are commercial units avalible.

What about your new discovery DX.?? 5/8 or 3/4 copper out to the pond, some 3/8 loops with manifolds and return. No circ. pumps. No heat exchangers, no antifreeze a huge advantage.

One other detail depending how much heat your trying to sequester with a tube and shell you may need antifreeze.
