[RE-wrenches] Hot Water Tanks

Thu Aug 28 06:00:40 PDT 2008

We have experience with STSS tank's. Lot's of Tarm's installed around here
in the past 10 years with that tank. Too many of the tanks leak after 8 to
10 years. That's why we decided to make our own tank.

Hiya Dave,
We installed an STSS tank at a very large thermal system in Colorado this
past winter.  Check out their website, excellent product.  If nothing else
this will give you a jumping off point in your research efforts.  The
website is stsscoinc.com.  Good to hear from you the other day...talk to you
soon.......

Wrenches,

Does anyone have a recommendation for a waterproof material to line a 950
gallon hot water storage tank? This insulated storage tank will have heat
exchange coils from a wood fired Tarm boiler as well as from SHW collectors.
The liner must be able to withstand temperatures of 180 degrees F.

We have had recommendations that include EDPM roofing membrane, and pond
liner material http://www.firestonesp.com/pondgard.asp?sub=b1a and
http://www.firestonebpe.com/lining/tech_data/tech_guidelines/_down/_en/T and
http://www.firestonebpe.com/lining/tech_data/tech_guidelines/_down/_en/T

Also, there is a concern that these tank liners have leaked in the past
because the bottom of the tank liner was eventually penetrated due to poor
protection from the stress of having the copper heat exchanger coils sitting
on it. I'm wondering if closed cell blue(or pink) board insulation would be
a good choice for this duty. Will it hold up over the years at temps up to
180F? As an alternative we could mill up some local Hemlock wood to separate
the coils from the liner. Hemlock has been used for years to build spring
boxes out of, the reputation being "that as long as the wood stays wet it
will last for decades".

And, is there a water treatment product that we should add to the storage
tank that will help protect the liner from breaking down over the years?

Thanks for your time,

I would ask that you contact Stephen Rhoades at Burke Industries: (800)
669-7010 x406, www.burkeind.com. Burke Industries is manufacturer of
Hypalon, one of the best single ply membrane roofing products. The same
(or similar) products are used for reservoir liners, pond liners,
waterproofing underground homes, etc. If you need to set something on
the membrane such as a heat exchanger coil, then have a pre-made walkpad
heat welded under the area of the coil. The walkpads are several times
thicker than the membrane itself and are made for rough service areas.
Stephen really helped me a lot on one of my large commercial projects.

Amigos y amigas,

I'm looking for a new or simply working old-style SMA SB 6000U.  Might
anyone have one they'd be willing sell me?  If so, please contact me
off-list.

thanks,
marco
