COR.set
Heat, power and storage. One set.
Generate heat and power. Store energy.
- COR.gen + COR.stor = COR.set
- up to 10 kW heat
- up to 2.2 kW electricity
- 92.5% overall efficiency (standard test)
Power in winter.
When photovoltaics deliver less and heat demand rises, COR.set generates heat and, at the same time, your own power.
COR.set generates this power while the system is heating anyway. How much it adds up to over a heating season depends on your system’s running hours — we work that out for your building in the initial consultation.
Heat demand and power generation over the year
Model calculation for an example building, values per month
With COR.boost, an immersion heater loads surplus power from the PV system and the storage unit into the buffer tank. In summer, COR.gen then hardly needs to start for hot water, if at all. COR.boost is in preparation.

Power generation and power demand · kWh of electricity per month
| Month | Photovoltaics, 10 kWp | COR.gen (heat and power plant) | Electricity demand (household and electric car) |
|---|---|---|---|

More power from COR.gen than from photovoltaics, in the model: November, December, January, February
Model calculation, not measured values. Example building: renovated detached house with 200 m² and four occupants in St. Pölten, Austria, 10 kWp of photovoltaics, one COR.gen, one COR.stor. Values rounded. Household electricity demand with one electric car (around 15,000 km a year): around 560 kWh per month in summer, 15% more in winter. COR.gen runs heat-led, mainly in the heating season. With COR.boost, the immersion heater takes over hot water in summer; without COR.boost, COR.gen starts up for it. How much power is actually generated depends on running time and building.

Three reasons for COR.set.
Heat + power.
One system generates both at the same time.
Energy when it matters most.
Your own power, especially in the heating season.
Generate + store.
COR.stor keeps the generated energy available.
Generate. Store. Control.
COR.gen generates heat and power. COR.stor stores energy. COR.app shows heat, power and storage.
Control
COR.app — Shows heat, power and storage.
Wood pellets
The fuel.
COR.gen
The heat and power plant.
Heat + power
Up to 10 kW heat, up to 2.2 kW electricity.
COR.stor
Stores the power until you need it.
Building
Receives heat and power.
Generate
COR.gen
The heat and power plant: it heats with wood pellets and generates electricity as it does. Up to 10 kW heat, up to 2.2 kW electricity.
Store
COR.stor
The battery storage system. 70 kWh usable, expandable to 210 kWh. Also takes in solar power and switches to backup power in a grid outage, typically within 20 ms.
Control
COR.app
The controls. COR.app shows heat, power and storage. You can step in at any time — at the unit or via the app. Faults go straight to the COR service team via remote maintenance.
Technology that makes the difference.
Fluidised bed, Stirling technology and flue gas scrubbing form the technical basis of the heat and power plant.
How the three work together is covered in the deep dives under Inside COR.

No plant room in the building? The COR.tainer — currently in development — is designed to bring the complete COR System in an ISO container, fully piped and wired.
