The Crown MS series indirect water heater is designed to generate domestic hot water in conjunction with a hot water boiler using forced boiler circulation. This indirect water heater consists of a 316L 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 other fluid other than water. It is also not intended for use in gravity hot water heating systems.
