Comparison
Verdict in brief
The DC 15-95 and DC 15-96 are the closest pair in the DC line: nearly identical input and output, but IBC rates the 15-96 at 96% AFUE against the 15-95's 95%, and the 15-96 weighs 105 lb versus 97 lb with a larger 0.5 USG vessel.
Published manufacturer figures. Input and output are kept separate; blanks mean the manufacturer did not publish that value.
| Specification | IBC DC 15-95 | IBC DC 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 % |
| DHW input | 15 – 95 MBH | 15 – 96 MBH |
| Max. DHW flow rate | 3 USgpm | 3 USgpm |
| Power use at full fire (internal pump) | 128 W | 128 W |
| Weight (empty) | 97 lb | 105 lb |
| Pressure vessel water content | 0.37 USG / 1.4 L | 0.5 USG / 1.9 L |
| 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 two models share the DC combi platform, coil ratings, gas pressure, altitude approval and venting limits. Their published ratings differ only slightly: 15–95 MBH input / 14.4–85.5 MBH output on the 15-95 versus 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 meaningful difference is efficiency: IBC rates the 15-96 at 96% AFUE, the highest in the DC line, while the 15-95 is rated 95%. Both allow a 3.0 USgpm maximum DHW flow and share the 0.5 USgpm activation threshold.
Physically the 15-96 is heavier at 105 lb (48 kg) versus 97 lb (44 kg) and holds 0.5 USG (1.9 L) versus 0.37 USG (1.4 L). Both are covered by DC I&O manual 120-183-A-R11, and both are discontinued.
IBC Technologies
The IBC DC 15-95 is a discontinued DC combi rated 15–95 MBH input and 14.4–85.5 MBH output at 95% AFUE, with a 3.0 USgpm maximum DHW flow and 120 ft of 3" venting per side.
IBC Technologies
The IBC DC 15-96 is the highest-efficiency model in the discontinued DC combi line: 96% AFUE, 15–96 MBH input, 14.5–85.9 MBH output, a 3.0 USgpm maximum DHW flow and 0.5 USG of vessel water.
IBC's DC specification table rates the 15-96 at 96% AFUE and the 15-95 at 95%; the two are otherwise near-identical on the published rows.
The DC 15-96, at 0.5 USG (1.9 L), against 0.37 USG (1.4 L) on the 15-95.
Yes. Both are listed in DC I&O manual 120-183-A-R11 (April 2020).
A consultation includes a heat-loss review so the size is right the first time.
