Portage and Main manufactures several types of outdoor wood boilers, including gasification and EnviroChip models. The company is headquartered in Saskatchewan, Canada. Portage and Main appears to be privately held.

Corporate History

Portage and Main was founded in 1973 by Andy Naggy in a small home workshop. Naggy retired in 2005 but the company continues to develop new products and sell them throughout North America. 

Product Lines

Portage and Main offers several series of outdoor wood boilers, including the EGR Optimizer wood gasification unit, which burns gases and exhaust in a secondary chamber at temperatures over 2000 degrees to produce efficiencies in the 85% range with lower emissions.

The Enviro-Chip series burns biomass chips of 1.5 to 2 inches and burns 1/3 to 1/2 less wood, according to the company. The Ultimizer series features a conventional outdoor boiler design and a fire chamber lined with 2-1/2 inches of refractory cement.
