this configuration is a TCS/TCW tank heater unit built on a two-pass U-bend bundle for in-tank heating with boiler water in the tubes. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Dimensionally it is a 6-inch shell unit, and roughly 57-1/8 inches overall in a 2-pass arrangement. That works out to about 22.1 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-275-06-060-001. Installations range across hydronic-fed storage systems, domestic water storage heating, and hot water storage tanks.
