IBC Technologies · Series
The IBC HC Series was IBC's discontinued wall-hung condensing heating boiler line, documented on the Technical Information Portal in seven sizes: HC 13-50, 23-84, 15-95, 15-96, 29-106, 20-125 and 33-160. Unlike the DC combis, the HC models are heating-only boilers.
Series facts
AFUE varies by model: 94% on the 13-50, 23-84, 29-106 and 33-160; 95% on the 15-95 and 20-125; 96% on the 15-96.
The HC Series is heating-only: its specification table lists no domestic-hot-water rows, just the space-heating coil (43.5 psig maximum operating pressure, shipped with a 30 psig relief valve) and space-heating water temperatures of 50–194°F. Seven sizes are published: HC 13-50, 23-84, 15-95, 15-96, 29-106, 20-125 and 33-160, spanning 13.5–160 MBH input with 94–96% AFUE.
IBC's official HC model list and specification table do not include designations such as HC 14-65 or HC 24-160; only the seven sizes above are published. The HC portal model list also shows discontinued HC 84 and HC 106 pages. The line uses 5"/14" w.c. gas supply, is approved to 12,000 ft altitude, and vents 120 equivalent feet in 3" or 35 feet in 2" per side. Power at full fire with the internal pump is 126–164 W and weights run 84–96 lb.
The HC I&O manuals remain public on IBC's portal: 120-185-A-R10 covers HC 13-50, 15-95, 15-96, 20-125 and 33-160, and 120-185-A-R9 covers HC 13-50, 23-84, 29-106, 20-125 and 33-160. The November 2019 gasket service notice applies to HC 33-160 units built July 2014–November 2016; owners should check the serial range with a licensed contractor.
