The SL Series G3 is IBC's wall-mounted residential condensing boiler line, available in four inputs from 85 to 199 MBH, running on natural gas or propane, with a V-10 touchscreen controller and a stainless-steel heat exchanger.
Series facts
95% AFUE for the 115, 160 and 199 models; IBC lists 96% for the SL 10-85 G3 only.
The SL G3 is a heating-only condensing boiler. It does not produce domestic hot water on its own; IBC documents connecting an indirect water tank directly to the boiler without a primary loop, which keeps the piping simpler than many combi-plus-tank arrangements.
Four sizes cover most detached homes and townhouses in the Lower Mainland: SL 10-85 G3, SL 14-115 G3, SL 20-160 G3 and SL 30-199 G3. The first number is the minimum input in MBH and the second is the maximum, so an SL 30-199 G3 modulates between roughly 32 and 199 MBH input. Choosing between them depends on a heat-loss calculation for the building, not on floor area alone.
IBC's own documents disagree on turndown: the Canadian brochure headline says up to 10:1 while the individual model pages say up to 8:1. Boilers.ca lists the model-page figure. Efficiency is 95% AFUE for the 115, 160 and 199 models; the 96% figure in the brochure applies to the smallest SL 10-85 G3.
Highlights

The IBC SL 10-85 G3 is the smallest SL Series G3 boiler: 10.6 to 85 MBH input with a 96% AFUE rating, wall-hung and available for natural gas or propane. It is the size to consider for compact homes and low heat-loss buildings.
IBC Technologies
The IBC SL 14-115 G3 is a wall-hung residential condensing boiler with a 14 to 115 MBH input range and 95% AFUE, running on natural gas or propane. It is the size most often matched to a typical Lower Mainland detached home with radiators or in-floor heat.
IBC Technologies
The IBC SL 20-160 G3 is the 160 MBH member of the SL Series G3: a wall-hung, 95% AFUE condensing boiler for natural gas or propane, bridging the 115 and 199 models for homes with higher heat loss or hot-water loads.
IBC Technologies
The IBC SL 30-199 G3 is the largest residential SL G3 boiler: 32 to 199 MBH input, 95% AFUE, natural gas or propane. It suits large homes, homes with high hot-water demand through an indirect tank, and some small multi-suite buildings.

Services for IBC Technologies boilers
No. SL G3 boilers are heating-only. Domestic hot water is provided by connecting an indirect tank, which IBC documents as a direct connection to the boiler.
Sizing follows a room-by-room heat-loss calculation of your home, the emitters you have (radiators, in-floor, fan coils) and any indirect tank demand. Square footage alone is not enough. The IBC line runs from 85 to 199 MBH input.
IBC specifies 3" Schedule 40 or 3" polypropylene (PPs) flue, with either direct-vent (sealed) or indoor air supply. Maximum equivalent vent length differs by model, so check the model page and the installation manual.
