Marc Caluwe
A trained mechanical engineer and native of Belgium, Marc Caluwe moved to the United States in 1998. Caluwe Inc. was started in 2005 with a focus on residential heating with small European hydronic wood stoves.
In 2010 Caluwe expanded its product offerings to include one of Austria’s premier wood pellet boiler lines through an exclusive North American relationship with Windhager.
Recognizing the need for proven wood chip technology, Caluwe expanded his line to include Heizomat, one of Germany’s leading wood chip boiler manufacturers with over 35,000 installations globally.
Windhager and Heizomat provide Caluwe with the ability to use diverse woody biomass fuels in a wide range of applications, including making both heat and electricity. In 2015 Caluwe entered a relationship with Spanner to bring their micro-scale biomass fueled combined heat and power systems to the U.S. market.
Through strategic relationships with numerous partner companies, Caluwe has the capacity to design, develop, install, and service projects throughout the country. Caluwe’s 350+ installations stand as testament to its success as one of America’s leading biomass system design/build companies.
