Stelpro

What Stelpro does

Stelpro Design Inc., founded in 1981 and headquartered in Saint-Bruno-de-Montarville, Quebec, is a privately held, family-owned manufacturer of electric heating appliances and HVAC systems, self-described as North America's largest producer in the electric heating category. The company designs and manufactures a broad product portfolio covering residential heating (baseboards, convectors, fan heaters, radiant and infrared panels, portable heaters), commercial and architectural heating (architectural baseboards, air curtains, cabinet heaters, explosion-proof units, unit heaters), heat pumps and HVAC (central, multizone and single-zone ductless systems, electric furnaces, make-up air units), heating cable systems via the Flextherm sub-brand, electronic and mechanical thermostats including the Wi-Fi connected CONCERTO line, and a small hand-dryer line.

Revenue is generated principally through hardware sales distributed via a multi-tier network of electrical distributors (Sonepar Canada, Affiliated Distributors), buying groups (AQMAT, iMark Canada, Octo, Spancan), electrical retailers, and trade associations (CMEQ, HRAI, Électro-Fédération Canada, Alberta Electrical Alliance, BCEA) across Canada and the United States. Pricing is quote-based for commercial and industrial projects, with unit-priced consumer accessories spanning roughly CAD $40-$1,345. Stelpro emphasizes quality and compliance as a differentiator, holding ISO 9001:2015, CSA, ETL, UL, and TÜV certifications, and Hydro-Québec's Mieux Consommer energy-efficiency certification for its electronic thermostats.

The company operates three sub-brands (Flextherm, Uniwatt, True Comfort) and runs manufacturing capacity at its Quebec headquarters and at the Terrebonne facility of Métal BF, acquired in May 2022. The company employs 500+ staff and serves residential, commercial, institutional, industrial, and agricultural end markets across North America.
