MAIN FEATURES

Advanced split design for maximum efficiency

  • Air-to-water heat pump of split design

  • The most valuable parts of the heat pump are stored in a unit inside the building

  • The connecting pipes of the indoor and outdoor units form the low pressure (cold) part of the cooling circuit, so that heat loss through the pipework is completely eliminated

  • Distance between indoor and outdoor units up to 15 metres

  • Low heating water volume requirements in the system

  • Support for connection to the power cascade without the need for 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 and therefore protected against the weather. It contains the most valuable parts of the pump including a frequency-controlled compressor, an electronically controlled expansion valve, control electronics, circulator and more.

Outdoor unit

It is more dimensionally efficient than the BoxAir Inverter all-in-one pumps. It includes an evaporator and ultra-quiet fans with widely variable speed control. Thanks to the compressor located in the indoor unit, the outdoor unit is even quieter than the BoxAir Inverter all-in-one model. The durable all-aluminum 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 of the outdoor unit due to the presence of only one fan and a smaller evaporator.

How it works

Discover the technology behind

Air-to-water heat pumps are based on the principle of extracting heat from the ambient air, whose temperature can be many degrees Celsius below zero. The heat extracted from the environment is transferred by the heat pump to the heating water that heats the building, or is used for the preparation of hot water. The system achieves a seasonal efficiency of up to 4.5 times higher than that of a conventional electric boiler and thus delivers significant energy savings.
