Generate electricity & heat from pellets & solar yourself all year round
Make your desire for independence a reality
myEnergy365 from ÖkoFEN is the answer to the question of how to generate electricity and heat independently and ecologically in your own home.
The holistic approach, which intelligently combines the latest technologies, opens up the unique opportunity for the first time to utilise totally ecological heat and self-generated electricity from pellets and the sun in a detached house. The concept is modularly structured. The innovation is offered as a complete system, although it can also be implemented step by step. An existing photovoltaic system can be integrated and the Stirling engine for electricity generation retrofitted at a later date.
This allows consumers to become gradually more independent in the manner best suited to their requirements and budget.
The Pellematic Condens
The core component of the power-producing pellet heating system is the Pellematic Condens, one of the most efficient pellet boilers with condensing technology.
Pioneering Condens condensing technology helps achieve an efficiency of 107.3%* combined with minimum emissions. Thanks to its compact design, the pellet boiler also fits into the smallest of boiler rooms and leads the way in terms of efficiency and space savings.
The pellet boiler can be equipped with a Stirling engine for electricity generation either straight away or at a later date. The Pellematic Condens is supplied with an eReady pack for the retrofitting option. Prepared interfaces on the controller and hydraulics enable subsequent installation of the Stirling engine, thereby providing the first step towards energy independence.
Step-by-step towards energy freedom
A PV system meets approximately 30% of the power requirements of a detached house.
The space required for installation amounts to approximately 35 m2 of roof surface. Existing PV systems can also be integrated. On sunny days, the unused electricity is fed into the public power grid.
Power storage unit
The power storage unit makes an ideal addition to the PV system and enables around 70% self-sufficiency.
Storage of the solar power allows it to be used even after the sun has long since called it a day. The emergency power function also makes the system a blackout provision, because a Stirling engine can provide electricity in the event of mains failure.
Power-generating pellet boiler
The Stirling engine is driven by the pellet boiler and also supplies alternating current (230 V, 50 Hz) on sunless days when little yield can be expected from the PV system. This is more frequently the case between October and March.
A Stirling engine enables the achievement of 100% self-sufficiency.
The Pellematic Condens_e
The core component of myEnergy365 is the Pellematic Condens_e, a pellet boiler that also generates electricity. In addition, the heating system is supplemented with a Stirling engine. In contrast to petrol and diesel engines, where combustion is internal, heat is supplied to the Stirling engine from the outside.
This engine filled with helium is located above the pellet combustion zone. The energy is produced by two different temperature zones that heat and cool the working gas. Expansion of the gas creates a pressure wave that moves a piston and generates electricity.
The Stirling engine is operated by the heat from the pellet boiler, with very little increase in pellet demand. This enables cost-effective electricity generation. A short response time makes the electrical output available very quickly. Another benefit is that the engine is maintenance-free.
