Quiet Mark is the international award for excellence in quiet product design and is awarded to worldwide manufacturers of the quietest products in conjunction with the Association of Noise Abatement Society. Quiet Mark sprang from the response to public complaints received by the Noise Abatement Society, concerning the volume of excessive noise made by household tools and appliances. Since launching in January 2012, Quiet Mark has significantly changed the way people and manufacturers view products, creating a demand for using quieter technology in homes, workplaces and in the open air. Vaillant is proud of the fact that our domestic boilers and renewable heat pump products have all been independently verified and judged to be one of the quietest products of their kind on the market, meaning our products not only perform to the highest standard but are as equally environmentally friendly. Not only is this a high honour in itself, but we are also the first heating technology brand to receive this accolade. With this award we join an exclusive collection of brands including Dyson, Samsung, Lexus and Sennheiser. Find out more about Quiet Mark here.
