  • Curtails the emission of greenhouse gases

This makes it an ideal choice for anyone looking to reduce their environmental footprint.

The heat pump accomplishes this efficiency by pulling in outside air, passing it through a heating coil, and directly heating the water. This process is not only efficient but also environmentally friendly. In fact, compared to conventional systems that heat water, the Dux Airoheat can reduce greenhouse gas emissions by over 60%. This makes it a great choice for those who cannot offer suitable roof space for solar panels.
