Portage and Main Boilers

The “Standard” Wood Boilers

Portage and Main boilers are the standard boilers that all others have been judged on since 1973. Made in Canada, by a wholly owned Canadian company. Over the years we have changed our fire box design to become the hottest stove in the market. The hottest refers to the bottom part of the furnace when the temperatures are allowed to reach much higher temperatures than any other competitors. When you achieve higher temperature in a stove you get better gasification of the wood, and you get less smoke, and less of other things coming from the stack. This innovation came from years of research , trial and error to get this Canadian innovation to market. We also want to share that once your boiler reaches the end of life, this boiler is fully rebuildable on site at your location. This is a unique feature of these furnaces that other competitors do not have. They will want you to buy a whole new boiler.
