Since 1999 we develop efficient, economic free piston Stirling engines of a new, so-called resonance concept.
The heating energy first serves to produce electricity in a generator at high efficiency. The "waste heat" of the process remains available for heating purposes. Primary energy is used efficiently; Energy sources include natural gas, biogas, wood (pellets, chips, etc.), fuel oil, rapeseed oil or other fuels.
