to be fabricated from solid 90/10 copper-nickel, 304L or 316L Stainless Steel ) and shall not require any type of anodic
protection. The tank shall be designed and fabricated with non-ferrous copper-silicon threaded tappings and non-ferrous
inlet and outlet piping for maximum corrosion resistance. Steel tank tappings will not be acceptable. The entire tank is to be
insulated with a minimum of 2" (
ASHRAE standard for stand-by heat loss). The complete heater shall be supplied with a high impact colorized composite
protective jacket which cannot rust or corrode and does not require painting.

The cold water inlet shall be
strata-ow diffuser which prevents incoming cold water from mixing too rapidly with hot water in the tank. A
