Our History

Tarm Biomass® is a third-generation, family-owned business that has pioneered the sale and service of European central heating equipment in North America for over 30 years. Tarm Biomass popularized down-drafting wood boilers. We were fundamental to the introduction of the concept of thermal storage use with wood burning boilers. We introduced many firsts including the first bulk fed residential pellet boilers, the first lambda controlled wood boilers, the first automatic wood pellet boilers, and the first dry chip wood boilers.

Tarm Biomass’s® primary objective has been to offer European innovation in home heating solutions, paired with a significant commitment to consumer education and environmental awareness. Exclusive partnerships with ISO 9001 certified manufacturers allowed Tarm Biomass® to offer products with operational reliability, exceptional efficiency, and to promote the clean burning of carbon-cycle biomass that is critical to the lowering of net greenhouse gas emissions.

In the summer of 2024, Tarm Biomass® sold its Fröling boiler sales and service business to longtime customer, Froling Energy of Keene, NH (frolingenergy.com). Tarm Biomass® continues to sell parts for HS-Tarm, Scandtec, and Effecta boilers.

Our Partners

The small village of Tarm, Denmark is home to the HS Tarm Company, which was founded in the early 1900’s by Rasmus Soerensen as a blacksmith shop servicing the horse and wagon trade. His son, Hans, expanded the small firm’s offerings to include wood stoves and, eventually, central boilers that could be connected to remote radiators with pipes. The younger Soerensen, whose initials “H.S.” were eventually incorporated into the company’s name and logo, and manufactured his first boiler in 1927. The company is now owned by Hans Sorenson, the grandson of the founder of HS Tarm. The company produces 60% of the home boilers used in Denmark and is ISO 9001 certified.
