Our commitment to sustainability:
To provide a future-proof and sustainable energy supply in buildings, electrification in the heating industry must progress. The rapid shift from fossil fuels to renewable energies requires more efficient solutions.
Solar energy generation allows for more independence from the power grid, but to match the electricity demand of the grid and the building itself, the PV system, a non-programmable energy source, must be intelligently networked and managed.
This can be accomplished in part by combining photovoltaics with energy storage devices and smart heating pumps.
Our goal is to pave the road for this transformation by developing smart heat pumps capable of delivering comfort to end users, fully integrated with other renewable assets in the same building, on a smart grid, or even in a smart city.
