Reduce your heating costs with our most affordable heat pump ever. In DHP-AX we have used our accumulated heating knowledge to develop a flexible air/water heat pump that operates at high performance. Energy is taken from outdoor air, even down to temperatures as low as –16°C. DHP-AX can be combined with an existing heating system, or parts of it, for example a water heater. If you need a complete solution, you can easily supplement DHP-AX with the parts you need – your installer can offer a specially adapted indoor kit to obtain maximum efficiency. The flexible DHP-AX will suit your needs, however big or small they are, and you’ll never invest in more than you need. The DHP-AX consists of only two major units, the outdoor heat pump and the indoor control unit, which makes installation quick and smooth. And since the compressor is located on the outside there are no components that can creates noise on the inside, while the sound created on the outside is at a very low level.
