Following the Best of SHK Award, our KWL EC 70 continues its award-winning streak: readers of the haustec.de online portal have chosen our decentralised ventilation unit as the winner of the Readers' Choice Award 2026 in the ventilation category. Our versatile allrounder has proven its strengths once again.

With over 35,000 votes cast, the haustec.de readers' choice is the largest of its kind in the building services industry. A total of 35 products across nine categories were nominated.

The award was presented digitally to Helios Managing Director Gunther Müller. Additionally, a compilation of this year's award ceremonies has been published on haustecTV in late May

What sets the KWL EC 70 apart is its uncompromising flexibility: up to 85 % heat recovery rate, 70 m³/h air flow rate, A+ efficiency rating and a choice of surface-mounted or partially wall-integrated installation. With the optional second-room connection, the device can even ventilate entire residential units. The fact that this versatility has now also won over the haustec.de community is the most rewarding confirmation of our product development.
