    40 years of innovation

    Innovative heating technology for over 40 years

    For more than 40 years, we have focused on the development and manufacture of heating technology. Our aim is to combine technical innovation with practical solutions for a wide range of heating applications.

    Today, more than 200 employees contribute to the development, production and support of HDG heating systems. As a Bavarian family-owned company, we manufacture our products in Germany and offer solutions tailored to different customer and project requirements.

    This experience has established HDG as a specialist in wood heating systems.

    Our HDG philosophy in action

    For more than 40 years, we have been developing, producing and selling heating boilers in line with the five principles of the HDG corporate philosophy. These principles guide our work in product development, manufacturing, research and development, and cooperation with employees and business partners.

    They form the basis of HDG's long-standing presence in the heating technology sector.

    Gemeinwohl Ökonomie

    Economy for the common good - an economic model with a future.

    Value Tree

    From a family business
    to a modern family company

    The company's founder Karl Ackermann already knew how to manufacture heating systems that were popular due to their high quality and robustness. As a modern family company, we still rely on the values and ideals of the family business from which we are descended. 

    This is the basis for HDG's success – then and now.
