* Until the 2023 award round, the product score was given on a Likert scale from 1 to 5, with 5 being the highest value. Since round 2023/24, the product score has been transformed to a school grade scale (1 “very good” to 6 “unsatisfactory”).

The aroTHERM plus is flexible, quiet and environmentally friendly. Huge advantage: It is installed outside and saves space in the indoor installation space. As an air/water heat pump, it uses the free supply of air to generate heat and transfer it via supply lines to the indoor unit in the boiler room. The high hot water temperature of up to 70 °C also offers customised hot water comfort.
