ÖkoFEN to launch fully integrated pellet CHP and PV at ISH

ÖkoFEN has developed an autonomous residential combined heat and power (CHP) system that integrates a pellet boiler, Stirling engine, battery and a photovoltaic system to ensure maximum energy independence. The unique system will be presented at the upcoming ISH show in Frankfurt, Germany.

Beaming with pride, Stefan Ortner, Managing Director of ÖkoFEN gave a sneak preview of a modular integrated autonomous residential heat and power system with pellets and solar PV at WSED in Wels, Austria.

Austria-headed boiler manufacturer ÖkoFEN has announced that it will present an autonomous residential combined heat and power (CHP) system that integrates a pellet boiler, Stirling engine, battery and a photovoltaic (PV) system. The unique system enables single-family houses to be independent of power supply and will be presented at the upcoming ISH show in Frankfurt, Germany.

– Energy independence is one of the most important future topics. The autonomous supply of ecological heat and self-produced electricity is becoming increasingly important for many people. With this revolutionary system, ÖkoFEN customers will be able to supply themselves with 100 percent of ecological heat and self-produced electricity in the future, explained Stefan Ortner, Managing Director for ÖkoFEN during a sneak preview in Austria last week.

100 percent energy independence

In addition to pellet boilers that can be retrofitted with a Stirling engine for electricity generation, ÖkoFEN has developed a system that integrates a battery and a PV system to ensure maximum energy independence. All components of this system such as PV with an inverter, battery, and boiler with integrated Stirling engine are linked with online weather data and are processed and visualized in the ÖkoFEN controller.

The PV system produces electricity when the sun shines. In the morning, the evening and in times without sunlight, the Stirling engine of the wood pellet boiler is producing electricity. The electricity is supplied directly for household self-consumption, if needed, if not, all the energy is saved in the battery.

– We are proud to be able to offer the world’s one and only possibility to supply a house entirely with renewable energies. After a one-time refuelling of pellets, no energy needs to be bought the entire rest of the year, said Ortner.

Equipped with a battery and a PV system, the electricity generating pellet boiler powers itself and supplies up to 600 watts of surplus power which can be used directly or stored for other electricity consuming devices. In the event of a blackout, the system is able to start autonomous and is powered by the electricity of the PV system, the Stirling engine and/or buffer function of the battery without the grid. The whole energy system operates self-sufficient.

Modular approach

Together with this revolutionary approach, the Pellematic Condens_e, a wood pellet boiler system that produces electricity, celebrates its world premiere at ISH in Frankfurt. Modular design allows consumers to switch step by step to 100 percent ecological heat and 100 percent self-generated electricity.

The combinable modules are a pellet boiler with an e-ready package, a photovoltaic system, battery and, as a final step to self-sufficiency the Stirling power generation for the pellet boiler. The components for the self-sufficient family home and the new pellet boiler Pellematic Condens_e will be available from autumn 2017.

– This modular approach is of key importance for consumers, not least those that have already installed rooftop PV, but also for those that are planning an overhaul of their heating system. The modular approach provides future proofing towards full energy self-sufficiency, ended Stefan Ortner.
