HS Tarm Wood and Combination boilers, made in Denmark since the turn of the century, were first imported into the USA in 1977 by Tekton Corporation of Conway, MA. Tekton was starter by Walter Goodridge , who also was the first US importer of Lange Stoves .
HS Tarm became a large national brand in 1979 after being featured on the cover of Popular Mechanics Magazine. The country was in the midst of the second oil shock (1978-1980), and sales quicky became brisk with thousands of boilers being sold each year. In 1982 the company was sold to Alan Koenig with the base of operations remaining in Conway.
and an older video of some production in the plant: The company was moved to Medford, NJ and traded under the name Tarm USA. New products were introduced including the Excel boiler, which was a clean burning oil/wood or gas/wood unit. In 1994, the company was sold to Nichols Hardware of Lyme, NH.
