We offer a full range of outdoor wood furnaces designed for efficiency—burning up to half the wood of many competitors. Portage & Main Outdoor Boilers are built on the principle of the fire triangle, featuring a simple, durable design constructed from 1/4" cold-rolled steel. They’re engineered for reliability, performance, and long-term value. Proudly manufactured in Manitoba. Our team would be happy to walk you through the many additional features that set them apart. We also stock Polar Furnace, and carry a wide variety of parts necessary for installation and service. Contact us today to learn more or find the right solution for your heating needs!
