Part of the Zenith solar thermal range

The Zenith evacuated tube solar thermal collectors are ideal for both new build and retrofit applications. The Vokèra Zenith packages enable simple ordering of a complete Zenith system and are compatible with the Vokèra evolve S, Vision System or Mynute VHE open vent boilers and AquaFlow twin coil cylinders.

Zenith Evacuated tube collectors provide improved efficiency, making them a more viable option where the installation position falls outside of the ideal positioning for flat plate collectors. Also Evacuated tube collectors provide greater efficiency due to the vacuum within the glass tubes enabling them to retain absorbed heat for longer.


  • Ideal for new build and retrofit applications
  • Highly selective coating on copper absorber plate within each tube for excellent absorption
  • Pressurised system for optimum performance
  • Solar Keymark seal of approval
  • Greater application flexibility and efficiency
