The SG Pro Boiler has been replaced by Saint Roch Universal Boiler.

The BIASI SG Pro system is a European, three-pass, reverse flame path boiler design. This causes more complete combustion of the fuel increasing AFUE efficiency up to 86.9% while reducing NOX emissions. This BIASI boiler is a “mid-mass” boiler more suitable for radiant or radiator hydronic systems.. The SG Pro is constructed from GG20 cast-iron and is ASME rated to operate at 58 PSI and comes with a lifetime warranty. The SG Pro also complies with all international standards. Each SG Pro is assembled with a front hinge door that allows easy access for maintenance.
