Corporate History
Martin Lunde, Dectra Corporation’s founder, began research in 1976 into what would become the GARN line of wood-fired hydronic heaters. The first prototypes were field tested in 1981, and in 1984 Lunde registered GARN as a trademark. In 2008, manufacturing space was doubled to meet demand for the wood-burning units.
