Family home
Your house as a power plant.
Heat and power from wood pellets, stored and controlled — so your house uses more of its own energy and needs to buy in less.
Many devices do not make a system.
PV on the roof, a heat pump, maybe a small battery: many households have invested. Yet the house still depends on the grid in winter, and in an outage much of it often stops — because the parts were not planned as one system.
What matters to you
Being less dependent, keeping energy costs under control, staying supplied during outages — with a matched system designed for a long service life.
When the question comes up
- New build or renovation
- The old heating system needs replacing
- The PV system should deliver more
- High energy costs
- Preparing for a longer power cut

What does COR.stor do for your home?
Work out how much of your own power you use with COR.stor and what you save — or how long 70 kWh lasts in a grid outage.
It is on your electricity bill. Without heat pump and electric car — you can add those under “Refine the calculation”.
Storage size
Each COR.stor offers 70 kWh of usable capacity, expandable to 210 kWh. Larger storage is designed individually.
