Bock Water Heaters
Founded by engineer Oscar Bock in Madison, Wisconsin in 1929, Bock Water Heaters has spent nearly a century specializing in oil-fired water heating. Their tanks are still manufactured in two Wisconsin locations and are what Bock bills as the #1 selling oil-fired water heater in North America. Bock builds glass-lined tanks ranging from 32 to 113 gallon capacities with high recovery rates that handle the heaviest hot water demand. In April 2025, Bock Water Heaters became part of the Bradford White Corporation, joining one of the most trusted names in residential water heating.
