Efficiently harnessing ambient air: the air-to-air heat pump.

The air-to-air heat pump keeps your home refreshingly cool in summer and warms it in winter, all without radiators. This works by extracting heat from the air and cooling it, or by tapping into the energy of the surrounding air and converting it into warmth, which is then distributed throughout your living spaces. With no need for underfloor heating or radiators, installation is straightforward, offering you low purchase and operating costs.
This system is perfectly suited for low-energy and passive houses equipped with ventilation systems as well as small vacation homes or individual rooms, ensuring cozy comfort wherever you need it. Technically speaking, this heat pump is a split air conditioning unit, also known as an air conditioner, whose efficiency is increased with fan coil units.

Please be aware: Heating efficiency decreases at very low outside air temperatures, as the energy source varies with the weather. More electricity is needed in winter, raising operating costs. These devices are perfect for areas where summer brings warmth and winter remains mild. It can be used as a single heating system or alongside an existing heating system to cool your rooms. Hot water heating isn't possible, necessitating a separate system.
Function of an air-to-air heat pump
How does an air-to-air heat pump work?
A heat pump system harnesses ambient air, making it usable for heating or cooling your home. This is achieved through a technical process, typically powered by electricity.

The heat pump systems extract energy from the surroundings and transport it to where it's needed, like your living room. Air-to-air heat pumps use the ambient air for this purpose to heat or cool indoor spaces.
Air-to-air heat pumps transfer the captured warmth through the air, earning them the name ventilation heating systems. The building requires no radiators, underfloor heating, or other heating surfaces. The energy source is the outside air or, more precisely, the exhaust air from your own property.
In cooling mode, the air-to-air heat pump uses the principle of heat extraction to effectively cool living areas. By reversing its heating operation, the refrigerant flows through the outdoor unit at low pressure, absorbing heat from the room and releasing it outside.


Different application options
For which application do you need a single-split or multi-split appliance?
Both single-split and multi-split systems are perfect for detached and semi-detached houses.
Single-split systems feature one indoor unit, making them ideal for cooling and heating small vacation homes or individual rooms.
Multi-split systems boast multiple indoor units, offering flexibility and efficiency.
In apartment buildings or commercial properties, you can combine several outdoor units in a cascade with various indoor units for tailored comfort and efficiency.
