Always one step ahead

Since the company was founded in 1989, ÖkoFEN has consistently been setting new standards in terms of ecology, economy and ease of use.

The innovations from ÖkoFEN are trendsetting for the industry:
the market launch of the first type-approved pellet boiler, the world's first pellet condensing boiler, the innovative pellet heating systems with micro combined heat and power (mCHP) that produce heat and electricity with a Stirling engine, or the Pellematic Condens pellet condensing boiler that can be combined with any heat distribution system – irrespective of the return temperatures. In order to make optimum use of free solar power in conjunction with pellets, ÖkoFEN as a system supplier also has solar thermal systems and buffer cylinders in its product range.
Since 2023 ÖkoFEN has also been developing the first heat pump with a truly sustainable control. By importing live CO2 and exchange electricity price data, heating periods and power output are optimised.


ÖkoFEN’s guiding principle

The products from ÖkoFEN have always been a byword for the highest energy efficiency and maximum ease of use. The secret: never settling for what has been achieved so far and constantly questioning and improving what has already been tried and tested.
