VELUX Systems
Like all VELUX products, the solar hot water system uses keen sense of design, premium materials and the latest technology.
VELUX have been developing solar products for over 15 years, applying the same levels of quality, design and innovation as their range of roof windows. The tank and collectors are guaranteed for 10 years and all accessories and components are guaranteed for 3 years. VELUX is an accredited member of REAL assurance, a consumer protections scheme set up to ensure a high quality experience for the home owner. The VELUX system meets all current UK and Irish standards. All plumbing elements are WRAS certified and electrical components are CE marked.
VELUX have got more than 50 years experience of roof integration. Therefore, they have been able to develop solar collectors that can be fitted easily, quickly and efficiently as they integrate into your roof. The result is a flush, sleek finish, with the collector looking like part of the building design.
