heat exchanger supports/hangers
I'd like to know what others have done to locate (support or hang) heat exchangers in storage tanks. In my case coils of soft copper and/or pex tubing. I don't want anything that penetrates or could chaffe the lining over time if I can avoid it. I'd rather not introduce metals and risk a galvanic corrosion cell. I thought of using a wood 2" x 8" or similar as a 'curtain rod' for the coils but don't know what would happen to the wood over time in hot water.
Anyone?
