Our company was founded in 2004 as the “Renewable Energies” division the Spanner group. We started with the production of pellet heating systems for well-known boiler manufacturers, then in 2008 we laid the foundation stone for our proven biomass power plant systems generating energy from biomass and waste materials. 

With more than 1,000 systems installed we are the leading manufacturer in the industry of decentralised biomass and residue gasification. Our technology is a sustainable alternative to fossil fuels, makes a major impact on CO2 reduction and is an efficient addition to the renewable energy mix.

With our mission "Rethink energy" firmly in mind: we are constantly working on innovations to rethink energy generation and offer our customers resource-saving energy solutions when they need them.

With a dedicated team of energy experts and a strong focus on research and development, we are constantly crossing the boundaries of what is possible. Our vision is to improve the energy landscape sustainably and in line with the circular economy.


Re² pellet heating systems
20 years of experience & development

We have been building modern pellet heating systems for 20 years now - initially as a supplier to well-known pellet heating system manufacturers. In 2016 we took over the Austrian brand HAPERO, giving us our long-standing industry know-how into the further development of pellet heating systems. We have been manufacturing and selling ever since in addition to our waste-based power plants and, we also have state-of-the-art Re² pellet heating systems.
