IBC · Canadian-built condensing boilers
SL Series
The SL Series (current G3 generation) is IBC's flagship residential condensing boiler: a wall-mounted, gas- or propane-fired unit that converts fuel into space heating at up to 96% AFUE. It heats water for the home's hydronic loop — radiators, baseboard or in-floor — and pairs with an indirect tank when domestic hot water is also needed.
IBC's flagship residential condensing boiler
The SL Series heats water for the heating system only. Residential models run from the SL 10-85 G3 up to the SL 30-199 G3, so Milani can match the output to the home's measured heat loss rather than oversizing.
The condensing heat exchanger pulls extra heat out of the flue gases that a non-condensing boiler sends up the chimney, which is where the efficiency gain comes from.
Efficient and serviceable
Supply and return connections are available on both sides of the boiler, which simplifies the near-boiler piping in a tight mechanical room. Internal layouts are designed for straightforward inspection, and parts are interchangeable across models in the series.
