ÖKOTHERM® Biomass Heating Systems – unique in diversity

A.P. Bioenergietechnik GmbH has been selling ÖKOTHERM® Biomass heating systems since the 1980s selling systems all over the world.

Increasing awareness for the environment and the knowledge that fossil fuels are finite has lead to a massive rethink in those responsible in the industry and the public sector as well as larger groups of buildings (e.g. agricultural businesses, housing estates, bio-energy villages, wineries, etc.). One of the unique selling points of our biomass heating systems is independence of fuels as well as the flexibility to change fuels depending on availability or requirements.

Contact us for a personal presentation of our systems, without any obligation to buy.
