Comparison
Verdict in brief
The IBC SFC 99-1 and NTI Trinity FTVN110C are both compact wall-hung combis near the 99-110 MBH heating mark at 95-96% AFUE, but their DHW and heating balances differ: IBC caps heating at 99 MBH with 2.4 GPM continuous DHW at a 70°F rise, while NTI heats 11 to 110 MBH with 2.7 GPM at a 77°F rise. The heat-loss calculation sizes the heating side; the DHW rating checks showers.

| Specification | IBC SFC 99-1 Superflow | NTI Trinity FTVN110C |
|---|---|---|
| Heating input, minimum | 15.5 MBH | 11 MBH |
| Heating input, maximum | 99 MBH | 110 MBH |
| Efficiency (AFUE) | 96 % | 95 % |
| Fuel | Natural gas or propane | Natural gas or propane |
| Weight (empty) | 85 lb | 107 lb |
| Max. equivalent vent length, 2" | 65 ft | 100 ft |
| Max. equivalent vent length, 3" | 120 ft | 150 ft |
| Heating water connections | 1" NPT | 1 1/4" NPT |
| DHW connections | 3/4" NPT | 3/4" NPT |
| Gas connection | 3/4" NPT | 3/4" NPT |
| Domestic hot water | Integrated coil in the main heat exchanger (combi) | Integrated combi (DHW plate) in the appliance |
Both are wall-hung combis that produce domestic hot water in the appliance, and both list natural gas or propane with a conversion kit. IBC rates the SFC 99-1 at 96% AFUE and caps its heating input at 99 MBH (29.0 kW), while NTI lists the FTVN110C at 95% AFUE with an 11 to 110 MBH heating range — about 11 MBH more heating headroom and a lower 11 MBH minimum fire on the NTI side.
Hot water is where the two philosophies show: IBC publishes 2.4 GPM continuous DHW delivery at a 70°F rise for the SFC 99-1 with a 4 GPM maximum DHW flow, while NTI publishes 2.7 GPM continuous at a 77°F rise for the FTVN110C. Both figures are continuous ratings at stated rises, so the practical test is whether simultaneous bathroom draws stay under the published flow at the home's incoming water temperature.
Installation packages are close: the SFC 99-1 weighs 85 lb (39 kg) with 1" heating and 3/4" DHW and gas connections, and vents 2" to 65 feet or 3" to 120 feet per side; the FTVN110C weighs 107 lb with 1 1/4" heating connections and vents 2" to 100 feet or 3" to 150 feet per side. Sizing starts from a heat-loss calculation plus the household's hot-water draw pattern.
IBC Technologies
The IBC SFC 99-1 is the smallest Superflow SFC combi boiler: up to 99 MBH input for space heating and DHW, 96% AFUE, wall-hung, with 2" or 3" PVC/CPVC/PPs venting. It is a fit for townhouses and smaller homes wanting one appliance for heat and hot water.
NTI Boilers
The NTI Trinity FTVN110C is the smallest FTVN combi: it heats at 11 to 110 MBH input and delivers 2.7 GPM of continuous domestic hot water at a 77°F rise, all in the same 107 lb wall-hung cabinet as the heating-only FTVN110.
NTI publishes 2.7 GPM continuous at a 77°F rise for the FTVN110C versus 2.4 GPM at a 70°F rise for the IBC SFC 99-1, though each rating uses a different temperature-rise basis.
Close, but not identical: the FTVN110C heats to 110 MBH input while the SFC 99-1 is capped at 99 MBH, so a heat-loss calculation decides which ceiling the home needs.
A consultation includes a heat-loss review so the size is right the first time.
