Sand at 800 °C.
Preheated air fluidises a bed of sand in the combustion chamber — pellets burn completely, without temperature spikes or slagging. Power plant technology, for the first time in a single-family home.
How it works
Two engines. No wear.
Two free-piston linear Stirling converters turn the heat into electricity. Helium-filled, no crankshaft, no lubrication — maintenance-free for life.
Wood pellets class A1.
The day hopper holds 40 kg and is filled automatically via COR.vac. At nominal load COR.gen uses about 2.7 kg per hour — and disposes of the ash itself: the flue-gas scrubber binds it in water, no ash pan at all.

FAQ
Frequently asked questions
COR.gen is a CO₂-neutral pellet combined heat and power unit for the home: from pellets it produces heat and electricity at the same time — up to 10 kW heat and 2.2 kW power from one unit.
It depends on your house, consumption and PV. Work it out with no obligation using our savings calculator — including self-sufficiency and CO₂ avoided.
COR.gen runs on wood pellets. Combustion releases only as much CO₂ as the tree previously absorbed — CO₂-neutral in the cycle. Almost half of Austria is forest, growing back sustainably.
Yes. COR.gen is black-start capable — it starts even without the grid. Together with COR.stor your home stays powered during a blackout: switchover typically under 20 ms.
COR.gen runs unobtrusively and is installed in the utility room — comparable to a conventional heating system, except it also generates electricity.
