Tarm Biomass

Innovative Leaders in Sustainable Heating Solutions

Tarm Biomass imports and distributes Fröling wood boilers, wood pellet boilers, and wood chip boilers and Effecta wood boilers.  We also represent several lines of accessory products including valves and controllers from LK Armatur.  Tarm Biomass  also stocks parts for HS-Tarm boilers that have been sold in North America since 1974. At Tarm Biomass we are wood burners at heart, focusing on selling appliances that burn wood fuels and accessories that support those installations.  The equipment lines we sell provide our customers with energy independence, enhance rural economic strength by keeping fuel dollars local, and encourage forest stewardship by providing uses for low grade timber.

We know that what we do is only sustainable if our products burn cleanly and operate efficiently, cost little to operate, and exceed our customer’s expectations. We encourage professional installation by trained dealers because we know that quality starts with the equipment and ends with the experience. We look forward to serving you.  Like you, we are feeling good about wood.

When You Choose Tarm Biomass Boilers, You are Not Alone!

Over 11,000 Sold Since 1974!

Wherever there is wood and the need for heat you will find our boilers.  It may not be obvious because our products are not sitting in the back yard belching smoke, but around the country and in Canada, Tarm Biomass boilers quietly and unobtrusively provide inexpensive, reliable heat for homes, businesses, schools, affordable housing, monasteries, churches, farms, pools, and a host of other applications.
