GSW Water Heaters:

Built for the Canadian climate, every model, be it gas water heaters, electric water heaters, or tankless systems, is meticulously engineered for performance and longevity.

A Legacy of Innovation

GSW’s journey began over a century ago and became firmly established in the domestic appliance industry when Beatty Brothers merged with General Steel Wares (GSW) in the mid‑20th century, forging a legacy of innovation in water heating. In 2005, GSW joined forces with A. O. Smith—a global leader in residential and commercial water heating—bringing expanded resources and reach, while remaining deeply connected to Canadian values.
