Who says that a heat pump can't also be an eye-catcher? The LA S-TU series is not only highly efficient, but also extremely individual… available in all 1625 colours from the RAL colour chart! This means that the machine can be adapted perfectly to the building façade, fits harmoniously into green spaces or can also set a clearly visible accent. Also: the exclusive perforated grid makes every colour shade that little bit lighter. A design cover is also available on request.

An air-to-water heat pump for outdoor installation can sometimes cause worry - for the owners and, even more frequently, for the neighbours: Help, too much noise! With the LA S-TU series, nobody needs to buy earplugs or worry about angry complaints. The result is pleasant to look at, but can’t be heard at all: State-of-the-art EC fans turn efficiently - and practically silently. And the innovative air circuit within the casing guarantees targeted filtration of those low frequencies that are perceived as particularly unpleasant.

And all that remains is the soft whisper of a gentle breeze.

 Reversible heat pump with cooling function.

All versions from 6 kW to 18 kW are also available in reversible design for heating and cooling. The advantage: just one system can keep you cosy and warm in winter and pleasantly cool in summer.
