MAIN FEATURES

Advanced Split Design for Maximum Efficiency

  • Air-to-water heat pump with split design

  • The most important components of the heat pump are housed in a unit inside the building

  • The connecting pipes between the indoor and outdoor units form the low pressure (cold) part of the cooling circuit, eliminating any heat loss through the pipework

  • Distance between indoor and outdoor units can be up to 15 metres

  • Low heating water volume requirements in the system

  • Supports connection to the power cascade without needing a third-party MaR (measurement and control) system

BUILT TO PERFORM, DESIGNED TO LAST

Compact and Quiet Heating Solution

Unique Indoor Unit

Typically located in the mechanical room of the building, providing protection against the weather. It contains the most important parts of the pump, including a frequency-controlled compressor, electronically controlled expansion valve, control electronics, circulator, and more.

Outdoor Unit

More dimensionally efficient than the BoxAir Inverter all-in-one pumps. It includes an evaporator and ultra-quiet fans with highly variable speed control. Thanks to the compressor being located in the indoor unit, the outdoor unit is quieter than the BoxAir Inverter all-in-one model. The durable all-aluminium construction of profiles and panels is long-lasting and resistant to weathering and corrosion.

Even Smaller Size

The BoxAir 22IS and BoxAir 26IS models offer a more compact size for the outdoor unit, due to the presence of only one fan and a smaller evaporator.

How It Works

Discover the Technology Behind It

Air-to-water heat pumps operate on the principle of extracting heat from the surrounding air, which can often be several degrees Celsius below zero. The heat collected from the environment is then transferred by the heat pump to the heating water that warms the building or is used to produce hot water. The system achieves seasonal efficiency up to 4.5 times greater than a traditional electric boiler, resulting in significant energy savings.
