Main Advantages

  • Increased efficiency: due to the tabular shape of the evacuated tubes they capture sunlight better as they have a greater surface area exposed to the sun at any time.
  • Minimum heat loss: since air is evacuated from the glass tubes to form a vacuum, it reduces heat loss from the tube.
  • Not affected by wind and frost as they can be used in subzero temperatures.
  • Require a smaller roof area than flat plate collectors.
  • Less affected by limewater.
  • More durable (20 year life span) and cheaper to repair.
  • A controller can adjust the hot water quantity.
  • Inner tank is made of stainless steel and therefore does not have the same level of moisture, condensation and corrosion problems as other collectors.
