The Grant Sahara collector has a durable aluminium frame with a bronze anodised finish which has been designed to blend with most domestic property roofs. During the manufacturing process, the use of premium material guarantees the collectors’ reliability and durability. Grant collectors have been tested to the requirement of BS EN 12975 and are certified with the Solar Keymark.
Heat Transfer Technology
Grant use a unique patented system where the heat transfer sheet interlocks both the pipe and absorber for perfect thermal transfer. Additional aluminium plates enclose the copper pipes and, combined with an industrial strength adhesive, result in 360° heat transfer. Soldered absorbers and ultrasonic welded absorbers provide far less contact making these options less efficient and more prone to water damage.
Do solar collectors only work in the summer?
No, many people believe that solar collectors can only work in the summer; however, free solar energy is available all year round. From May through to September, solar thermal could produce 100% of the energy require for heating your domestic water. Grant collectors operate not just with direct sunlight but also in diffused sunlight, so even on cloudy days they work.
