General Information
The Lochinvar SSS series indirect water heater (FIG. 1-1) is
designed to generate domestic hot water in conjunction with
a hot water boiler using forced boiler water circulation. This
indirect water heater consists of a 444 Stainless Steel tank in
which a smooth 304 stainless steel coil is located. Boiler water
is pumped through the coil and heats the water in the tank.
This tank is not intended for use in pool heating applications
or for heating any fluid other than water. It is also not
intended for use in gravity hot water heating systems.
