Input is gas energy consumed; output is heat delivered. Never size from input alone.
IBC HC 15-95 in practice
The HC 15-95 covers 15–95 MBH CSA input (4.4–27.8 kW) for 14.4–85.5 MBH output (4.2–25.0 kW) at 95% AFUE. It shares its heating-side ratings with the DC 15-95 combi but has no domestic-hot-water coil, so its specification rows stop at the 43.5 psig space-heating coil and 50–194°F water temperatures.
The unit weighs 91 lb (41 kg) — between the 23-84's 85 lb and the 15-96's 96 lb — holds 0.37 USG (1.4 L) and draws 128 W at full fire with the internal pump. Maximum boiler flow is 10 USgpm and the minimum is 2 USgpm; gas supply is 5–14" w.c. and the altitude rating is 12,000 ft.
The 15-95 is covered by HC I&O manual 120-185-A-R10. Venting is 120 equivalent feet in 3" or 35 feet in 2" per side, and the discontinued HC Series remains documented on IBC's Technical Information Portal.
Best suited to
- Owners documenting an HC 15-95 installation against the HC spec table
- Homes where 85.5 MBH output matches the heat loss and DHW is separate
- Technicians comparing the HC 15-95 with the 15-96
