Comparison
Verdict in brief
The HC 15-95 and HC 15-96 are near twins: almost identical input and output, but the 15-96 is rated 96% AFUE against 95%, holds 0.5 USG versus 0.37 USG, and weighs 96 lb against 91 lb. Both are heating-only and use the same manual.
Published manufacturer figures. Input and output are kept separate; blanks mean the manufacturer did not publish that value.
| Specification | IBC HC 15-95 | IBC HC 15-96 |
|---|---|---|
| Input, minimum | 15 MBH | 15 MBH |
| Input, maximum | 95 MBH | 96 MBH |
| CSA output, minimum | 14.4 MBH | 14.5 MBH |
| CSA output, maximum | 85.5 MBH | 85.9 MBH |
| Efficiency (AFUE) | 95 % | 96 % |
| Power use at full fire (internal pump) | 128 W | 128 W |
| Weight (empty) | 91 lb | 96 lb |
| Pressure vessel water content | 0.37 USG / 1.4 L | 0.5 USG / 1.9 L |
| Maximum boiler flow rate | 10 USgpm | 10 USgpm |
| Minimum boiler flow rate | 2 USgpm | 2 USgpm |
| Max. operating pressure, space-heating coil | 43.5 psig | 43.5 psig |
| Max. equivalent vent length, 3" | 120 ft | 120 ft |
| Max. equivalent vent length, 2" | 35 ft | 35 ft |
The published ranges are within a fraction of each other: 15–95 MBH input / 14.4–85.5 MBH output on the 15-95, and 15–96 MBH input / 14.5–85.9 MBH output on the 15-96, with 4.4–27.8 kW against 4.4–28.1 kW. The difference that matters is the AFUE rating, 95% versus 96%.
Both are heating-only boilers with the 43.5 psig space-heating coil, supplied 30 psig relief valve and 50–194°F water. They share a 10 USgpm maximum and 2 USgpm minimum flow, and the same 120 ft of 3" / 35 ft of 2" venting per side.
Physically the 15-96 is heavier at 96 lb (44 kg) versus 91 lb (41 kg) and carries the larger 0.5 USG (1.9 L) vessel. Both are covered by HC I&O manual 120-185-A-R10, and the HC Series is discontinued.
IBC Technologies
The IBC HC 15-95 is a discontinued heating-only boiler rated 15–95 MBH input and 14.4–85.5 MBH output at 95% AFUE, weighing 91 lb with 120 ft of 3" venting per side.
IBC Technologies
The IBC HC 15-96 is the highest-efficiency HC boiler at 96% AFUE, rated 15–96 MBH input and 14.5–85.9 MBH output, with 0.5 USG of vessel water and 120 ft of 3" venting per side.
The HC 15-96 at 96% AFUE, against 95% on the 15-95.
Only marginally: 85.9 MBH versus 85.5 MBH CSA output, and 96 versus 95 MBH maximum input.
Yes. Both are listed in HC I&O manual 120-185-A-R10.
A consultation includes a heat-loss review so the size is right the first time.
