An air/water heat pump is one of the most popular choices for home heating, as it uses the energy that surrounds us — air. It’s an affordable, quick-to-install, and efficient solution that can provide heating even at very low outdoor temperatures.
An air/water heat pump extracts heat from the outdoor air and, using a refrigerant circuit, converts it into energy for heating spaces or domestic hot water. These systems work efficiently even at temperatures down to –25 °C. As no drilling or significant groundworks are required, installation is fast, cost-effective, and simple.
Because outdoor temperatures vary, the system is designed so that the heat pump operates independently and efficiently for most of the year, even in cold conditions. In certain cases, an electric heater can provide additional support, but a well-designed system with a quality heat pump typically covers almost all annual heating needs on its own.
Air/water heat pumps combine energy efficiency, affordability, and easy installation. They can be used almost anywhere, as they require only access to outdoor air. Although their performance depends slightly more on the weather than ground or water source systems, modern units are designed to work efficiently year-round. The best air/water heat pumps, like the KRONOTERM ADAPT, offer efficiency that comes close to that of ground-source heat pumps.
Most air/water systems capture heat from the air using an outdoor unit. However, innovative solutions like the KRONOTERM VERSI work without an outdoor unit — air is drawn through vents instead. This design allows discreet and elegant installation in cases where an outdoor unit is not desirable or feasible.
Thanks to simple installation and fast implementation, the air/water system is an excellent choice for both renovations and new builds. It is especially suitable where drilling or ground collectors are not possible. The investment is usually lower than for other systems, which means faster cost recovery. Increasingly, air/water heat pumps are also used in apartments, enabling independent heating without a central system. Compact models like VERSI are designed for such spaces — they take up little room, operate very quietly, and can be installed on a balcony, in a closet, basement, or attic. This provides residents with comfort, warm water, and significantly lower heating costs — all without major building work.
