    I got me a 60 gal, propane tank and been seeing more about useing Ref. line for the coil? I have used type l copper in past been thinking now about which is best? If to thin will it corrode faster? And will the sweat fittings fit the 5/8 OD Ref, line if I use it? I guess it would bend[coil] up better to make correct size and what I read seems to say it can be used in water lines too. I plan on useing around 60 to 100 feet of it. This is for a friend I know he has old boiler and wants to add a dhw. heat from it. The 60 gal. is only size will fit his basement door or I use bigger tank.22 inch wide door is only 28. Thanks

    Hve you considered looking for a scrapped indirect? On mine the coil is bolted to a flange. Should be easy to unbolt and reuse the coil...

    Here you go: http://www.copper.org/applications/plumbing/techref/cth/cth_2select_recom.html

    That site doesn't address the specifics of selecting copper tubing for various applications. I have run across another article which considers the flow velocity over the life cycle of the tubing which takes erosion into consideration. The tubing is expected to erode over time. I'll see if I can find the reference.

    Thanks, I will see what you say before I make a decision, 5/8 type L is what I am leaning towards? 1/2 inch?
