Evacuated Tube Collectors

Thermomax evacuated tube collectors deliver an unrivalled transfer of solar energy into heat. The vacuum inside each of the tubes provides perfect insulation and reduces heat loss by protecting the system from outside influences. This results in a greater solar yield than traditional flat plate panels, resulting in increased performance and efficiency. All of our solar thermal collectors are MCS approved and are provided with an industry leading guarantee.

Overview HP400

Thermomax HP evacuated tube collectors is a ‘dry system’ recommended especially for ease of installation and maintenance. The superior vacuum inside Thermomax HP tubes protects the system from outside influences such as cold conditions or high humidity. Simple ‘plug and play’ design of Thermomax solar thermal collectors reduces labour time and maintenance.

  • Highly efficient – super fast heat transfer
  • Unique temperature limitation safety device – memory spring to limit temperature to 90°C (domestic installations) or 135°C (commercial/industrial installations)
  • Up to 30% more efficient than traditional flat plate panels
  • Supplies up to 70% of your annual hot water needs
  • Designed especially for Northern European climates
  • Asethically pleasing – slimline manifold
  • ‘Plug and play’ for ease of installation and maintenance
  • Dry fit of heat pipe tubes allows easy maintenance as tubes can be removed without draining the system
  • Up to 20 years guarantee (when installed by a Kingspan Accredited Installer)*
  • Excellent customer and technical support available
  • MCS Approved and Solar Keymarked
