Who We Are

Portage and Main Outdoor Boilers is named after one of the coldest intersections in the world – the intersection of Portage Avenue and Main Street in Winnipeg, Manitoba, Canada. This crossroads has over the years witnessed history in the making. This area was the hub of commerce and banking at the turn of the 20th century and still remains a vital link between the business communities of Eastern and Western Canada. Thanks to its relative proximity to the international border, it is also a vital link between Canada and the United States.

Company History


Portage & Main Outdoor Boilers was founded by inventor and entrepreneur Andy Nagy in 1973. From his modest home workshop, Nagy designed and built durable, highly efficient outdoor hydronic heating appliances. Using time-tested concepts and simple manufacturing processes, Nagy developed the Portage & Main brand. It is now one of the most recognized names in the industry. Although Nagy retired in 2005, manufacturing continues today with the same care and attention to detail he held so dear.
