The heat pump, reimagined.
We have developed the next generation of residential heating. Heat pump and ventilation technologies integrated into one system - unlocking new levels of efficiency and energy savings.
- One integrated system
- Higher efficiency
- Significant energy saving
- Cleaner indoor air
Vision / 02
Nothing should be wasted.
The cleanest energy is the energy never lost in the first place. Nature has always known this. In a living system nothing is discarded; warmth and air move from one place to the next, over and over.
We built BAS to work the same way: heating and ventilation as one system, where what one part gives up, another puts back to work. That's what we're building toward. Spaces that make the most of everything, wherever people live and work.
Market / 03
Europe is replacing millions of oil and gas boilers this decade. BAS technology is developed for that transition.
Across Europe, residential heating is going through its biggest shift in a generation. Tens of millions of homes still run on gas and oil, and they are steadily being replaced - driven by climate targets, government subsidy, and the economics of a volatile fossil fuel market. Heat pump is the core technology of that shift.
It creates a second, less obvious challenge. Older homes were ventilated by their boilers - combustion drew air through the building. Remove the boiler, tighten and insulate the house, and that natural air exchange disappears, making proper ventilation essential rather than optional.
BAS is built for this use case. It combines a heat pump with ventilation heat recovery in a single, integrated system - engineered for higher efficiency than standalone alternatives. As the market moves at scale, efficiency and simplicity of installation become the deciding factors.
Regulation and subsidy are key factors driving this transition. The EUs Energy Performance of Buildings Directive commits member states to decarbonise their building stock through 2050, raising standards for energy efficiency and indoor air quality alike. In Germany, the Building Energy Act (GEG) and subsidies continue to favour heat pumps for new installations, even as the specific rules are revised - and every home converted means less energy used and less carbon emitted.

Technology / 04
A heat pump that recovers energy from the air it exhausts.
A conventional setup treats heating and ventilation as two separate problems: a heat pump for warmth, and a ventilation unit that recovers some heat before releasing stale air outside. BAS connects them - so the energy that would otherwise be lost in the exhaust air is put back to work.
The integration operates on three levels, each targeting a point where conventional systems lose energy or reliability:
Exhaust-air energy recovery
It extracts additional energy from exhaust air, beyond what standard heat recovery captures, and feeds it into the refrigerant cycle.
Cold-weather efficiency
It sustains efficiency in cold weather, where standard systems lose ground to frost.
Valve-free energy direction
It directs energy between heating and hot water without a mechanical switching valve — removing a common point of failure.
This is protected by granted European and Swedish patents.
Benefits:
Lower energy use
Around 25% less than a heat pump and ventilation system installed separately.
Lower installed capacity
The same heating demand met with a smaller unit, because ventilation recovery carries part of the load.
Improved reliability
A common mechanical point of failure has been engineered out.
Validation / 05
Validation of the BAS technology
BAS Air Energy has already taken concrete steps to protect and validate the core innovation behind the technology.
The core technology is protected by granted European and Swedish patents covering the integrated system principle. In collaboration with KTH's Energy Department and with grant funding from Energimyndigheten, we built a working prototype and demonstrator, then tested it extensively in KTH's climate chambers to validate the system's technical performance. That foundation now underpins the development of a consumer-ready product.
Patented technology
European and Swedish patents protect the integrated system at the core of BAS.
Independently validated
Core performance quantified and confirmed through extensive testing in a university laboratory environment (accredited).
Proven in prototype
A first prototype has demonstrated the concept in operation — the basis for the consumer-ready system now in development.
BAS Air Energy has been selected to take part in KTH Innovations Launch program.
Team / 06
Senior industry leadership, applied research at KTH, and manufacturing and installation expertise.
An experienced team that has run global home comfort businesses at Electrolux - leading business development, product innovation, and patent strategy. That sits alongside ongoing research at KTH Energy Technology and manufacturing and installation expertise from Härnösand - a mix of industry, academic, and engineering depth not often found at this stage.
