Kwiksol Direct System Close Coupled – Cistern Type

  • SOL-110-LP
  • Used in frost and frost-free locations i.e. inland and coastal areas.
  • Working pressure 0kPa.
  • 304 stainless steel 110lt inner tank.

Low Pressure Solar Water Heater and Self Filler Tank

  • 304 stainless steel 110lt tank covered in galvanised outer casing. IPX4 rated.
  • The horizontal solar water operates at zero pressure and relies on gravity to feed water to the taps.
  • The self filler tank controls the water flow into the solar water heater. The self-filler tank has a high pressure float ball valve, which allows for a direct connection to the municipal mains supply, without any additional valves.
  • The solar water heater relies solely on solar radiation transmitted via an array of vacuum tubes to heat the water and does not have an electrical element and thermostat as a back-up.

Solar Vacuum Tubes Features

  • Vacuum tubes consist of two glass tubes manufactured from borosilicate glass.
  • The outer glass is transparent allowing light rays to pass through with minimum reflection.
  • The inner glass is coated with a special solar selective coating (Al-N/A1), which provides excellent solar radiation absorption.
  • The tops of the tubes are fused together and the air extracted, which forms a vacuum, which is key to the efficiency of the vacuum tubes.
  • If the vacuum is ever lost, the silver inner coating will turn white.
  • The water is directly heated in the vacuum tubes.
  • Tubes are freeze and hail resistant.
