A Coil for a heat exchanger??

Has anyone ever used an A coil for a heat exchanger with a wood boiler. I have a new one left over from a job some time ago. It just sits around the shop here. It seems to me it would make a great water to air heat exchanger, although I know they are really designed for AC. I wonder how different hot water running thru it would be compared to freon. I think it would also make a fantastic side arm if immersed in boiler water to make domestic hot water. Any thoughts??

I dunno about heating domestic water with them, but I've been saving them for use in heating thermal storage tanks.
