copper lined storage

[smangold]

has anyone ever thought of soldering sheets of copper together ,to line a copper or wood tank.Enough copper for a 3x4x8 tank would be $ 600 in 3x8 or 3x10 sheets. thoughts?

For $600, I think you could buy a complete used tank. My 880 gallon stainless tank was $400, and I think the going rate for used LP tanks is around $500 for a 500 gallon tank. I don't know how well a soldered lap joint would hold up to the tension load of a full tank.

If you could make rolled seams and solder better than me, you could probably make it work.

I would like to know why you would want to line the storage with copper or any heat conducting material? What is your goal in doing so? It looks expensive, have a real problem with joining the edges, and serve no advantages, educate me.

mr. nofossil , your'e right I might find a tank cheap.Things like that are hit and miss though. Why would I think of a copper liner... Well the high temp limit of the edpm makes me nervous. I have baseboard heat and feel it would be advantageous to heat storage as high as possible.I think I'm going to buy the Swizer I looked at last night anyway(with built in storage) I guess It's a moot point anyway.

I believe Polypropelene liners can withstand higher temps. Let us know if you go with the Swizer and how you like it!

Firestone is one of the manufacturers of EPDM and I talked to one of their engineers about high temps. He said it was rated for 170 or 175, I can't remember which. When I asked him if it could handle 180-190 for extended periods he said he thought so, but wouldn't guarantee it. Lots of people have had these tanks for a lot of years with no problems so I'm not worried about failure. Even if the liner needs to be replaced in 5 years it's only a couple hundred bucks, certainly cheaper than copper.

Reg, I like the firestone too, the manual says service life no higher than 180 F or 82 C

It is covered by a 20 year promise to replace, but I think I am aiming for 10 years. although 20 would be awesome.
