Evacuated tubular solar thermal collector
Vaillants latest vacuum tube collector is manufactured using toughened glass and each tube is internally coated with a special high selective absorber coating.
Each collector is delivered pre-assembled with 6 tubes per collector, and is compact and lightweight for ease of installation. The tubes have the benefit of a 10-year guarantee against loss of vacuum and if necessary, can be replaced without draining down the solar system. Collectors can be connected together and up to 12 collectors can be connected in series, using black ionodised roof brackets providing a neat and attractive installation.
The external Compound Parabolic Concentrator (CPC) ensures that solar radiation is efficiently directed toward each tube and has a ceramic coating to limit the build-up of dirt. Total siting flexibility is provided by an extensive range of roof brackets for concrete profiled or flat tiles, as well as low profile brackets for slates and A-frames for flat roof installations. The auroTHERM exclusive collectors are fully tested and approved to EN 12975.
The auroTHERM exclusive VTK 570/2 are Solar Keymark approved and therefore quality for grant funding where applicable.
