300liter Heat pipe pressurized Solar Water Heater

Working Principle

Vacuum tube collect heat from sunshine, aluminum ring inside transfer the heat to heat pipe, then heat pipe transfer the heat to water inside tank, the system start and transfer heat is quick in cloudy and low radiation days, daily average heat efficiency can up to 55%.


  • High thermal performance and working temperature: the heat exchanging rate even in winter can up above 55%.
  • Heat collecting efficiency is at least 20% above common solar systems.
  • Work in all day and all season: no matter any corner of the world, this system can work well even -40 to avoid the tube freezing problem.
  • Reliability: No water following through the tube, so water scale can not generate and tube cracks could be avoided, the system still can keep working even with some damaged tubes.
  • It can connect with water tap and work automatically with pressure0.6Mpa, bring enjoyable washing experience.
  • Safety: P/T valve would release pressure and temperature to protect tank..

Technical specification:

  • Outer tank material: SUS304 stainless steel or powder coated color steel
  • Inner tank material: 1.2mm thick SUS304 food grade stainless steel ( Optional material SUS316L)
  • Vacuum tube material: borosilicate glass 3.3; AL-SS-CU absorb coating, with copper heat pipe inside
