Solar Thermal

NuVision Energy’s unique “SunStream Solar Water Heaters”, are produced in a state-of-the-art factory, which is one of the largest such facilities in the world. They use a triple coated absorber that converts up to 96% of the energy captured, and its’ circular design presents a perpendicular absorber area throughout the day, maximizing the gain from both direct and indirect solar radiation.

The collector manifold and frame is made from high quality aluminium, powder coated black for long life and smart appearance. The extensive Sun Stream Solar Heating Panels range includes systems for both domestic and commercial applications, and has over the years been installed in over 100,000 sites. Clients have included government and local authority bodies together with many large corporations.

The company’s products carry both EN certification and the European Keymark, as well as many other international approvals.

Specifications

Vacuum Tubes Data

Sun Stream vacuum collectors use a triple coated absorber that converts up to 96% of the energy captured. The 360 degree absorber design presents a perpendicular absorber area throughout the day which enables the collector to absorb the maximum energy from both direct and indirect solar radiation. The advantage of this technology is improved thermal efficiency, lower emittance rate and a working efficiency in high temperatures of up to 200°C. High quality borosilicate glass is used throughout.
