About Cadet

The comfort of your home begins at our home in the Pacific Northwest, where Cadet has been inviting warmth since 1957. Every one of our baseboard and electric wall heaters is designed and built at our facilities in Vancouver, Washington, USA. As a family-run business, Cadet keeps it simple: build the heaters that we’d want to keep our own families warm, comfortable, and safe. We don’t believe in heating a room you’re not in, so Cadet delivers warmth one room at a time. That’s the simple, sensible efficiency of single room heating. Choose Cadet for a smart, sustainable choice you’ll rely on for years to come.
