Quick installation, even without refrigeration accreditation

Optimally coordinated system components and already integrated hydraulic components enable fast and uncomplicated installation. This can also be done without refrigeration accreditation, because there is no need for intervention in the refrigeration circuit.

Modulating versions

Ideal for changing demand, the frequency-controlled variant of the LWA series provides necessary capacity reserves and is characterised by its particularly high efficiency. The frequency-controlled system adjusts the heat generated to the respective current heat demand of the building and outputs constant, demand-orientated heat.

Small space requirement

The heat pump installed outdoors and the compact system components save valuable space inside the building and are therefore perfect for houses without basements.

Very high efficiency

Regarding energy efficiency heat pumps are the frontrunner among heat generators. alira air/water heat pumps fulfil future requirements of heating systems achieving energy class A+++ in combination with the controller.
