AeroWIN Klassik

Affordable entry-level model for new buildings

The AeroWIN Klassik air/water heat pump is the perfect heating solution for modern detached houses and apartments with low energy requirements. It takes free energy from the ambient air and converts it into comfortable warmth for heating. The AeroWIN works extremely efficiently. The unit continuously adapts its output to actual requirements and achieves a high energy efficiency class of up to A++ even with flow temperatures up to 60°C. This allows you to heat your home in an environmentally friendly and very economical way.

AeroWIN Klassik

Whisper quiet and compact

The AeroWIN air/water heat pump requires very little space. Thanks to flexible connection and installation options, it can be easily installed outside your house. Since all AeroWIN models work on the monoblock principle, it operates very reliably. In addition, installation and maintenance costs are very low. An extra bonus is that the technician does not require a refrigeration certification to install it.

Tip: Install the AeroWIN Klassik on a foundation with a suitable recess; matching brackets and connection sets are optionally available.

The AeroWIN is not only highly energy-efficient, it is also extremely quiet. At a distance of five metres, the sound pressure level is only about 30 decibels – roughly equivalent to the operating noise of a modern refrigerator. If required, the silent mode function ensures barely audible operation – at night, for example.

Tip: You can find our sound calculator here.

All safety-related components and those required for distributing heat in the house are accommodated in the AEHM hydraulic module to save space. This includes an energy-saving heating circulation pump, safety fittings such as the expansion tank, and supplementary heating for occasional peaks in demand.
