Configured for in-tank heating with boiler water in the tubes, this configuration carries the two-pass U-bend bundle construction that defines the TCS/TCW tank heater range. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. The configuration measures 14 inches across the shell, 36-inch shell length, and roughly 37-1/2 inches overall in a 2-pass arrangement. That works out to about 86 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies 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. Installations range across hydronic-fed storage systems, domestic water storage heating, and hot water storage tanks. This build is designated 5-275-14-036-001.
