Failure of a tank’s protective lining allows
water to come into direct contact with the
steel tank causing it to corrode and leak.
Therefore, the type of protective lining is

the single most important feature when
determining the quality of any water heater.
The ability of a lining to protect the steel tank
is primarily based upon its thickness and
complete coverage of all steel surfaces.

" thickness on all

surfaces. The cement lining covers 100% of
all interior surfaces and is 125 times thicker
than glass lining. Due to the thickness and
guaranteed coverage of cement lining there is
no need for a sacrificial anode. An extremely
durable and long lasting lining suitable for hot
and cold potable water storage in a variety of
commercial and industrial applications.

An epoxy coating applied in 2 coats to a total
of 10-12 mils DFT. Typically used in process
applications using low conductivity DI, distilled,
or food grade water.

A solid Non-Ferrous tank does not require a lining because the pressure vessel itself is

constructed from material which is impervious to the corrosive effects of hot water. This type of tank
will provide a significantly longer service life than all lined steel tanks, but is initially more costly.

A 90% Copper 10% Nickel alloy provides
excellent strength and corrosion resistance.
Typically used in applications with corrosive
environments (salt water) or in critical marine
applications requiring long tank life.

Stainless Steel (Specify: Type 304, 316, or
316L) is suited for applications requiring a
corrosion resistant tank with minimal leaching
of impurities into the water. Well suited for
process, RO, and DI water systems.
