Germanstar HP 70 – Quality “Made in Germany”

Our full vacuum collector Germanstar HP 70 is “Made in Germany” and offers high yields even on so-called ‘low-light days’. Different from other heatpipe collectors, the Germanstar HP 70 can be rotated from 3-90 degrees and therefore, can be used universally – horizontally or vertically on roofs and facades as well as by stand-alone mounting. This high-performance collector is most suitable for solar supported heating.

Key data

  • Tube diameter 70 mm
  • Heatpipe full vacuum collector
  • Rotatable from 3-90 degrees and therefore, multiple installation options
  • High low light yields due to fast reaction
  • Very high yields in cold environments (winter)
  • Very good wind behaviour when installed on stands
