Flat plate system VS evacuated system

TianShang Flat-collector System

Evacuated tube pressurized system

Evacuated tube collector thermophyson system


Max working Pressure


0.8mPa to 1.0mPa

Without any pressure, just something like MAX 0.2mPa

Tank and collector split or integrated



Integrated or split

Direct or Indirect system

Better indirect

Better indirect


Life span suppose to use

20 years

10 to 20 years, depending on system design

Usually around 10 years. The cotact place between glasstube/manifold is week, which is a rubber ring and thus can age easily and thus easy to get off if water pressure change suddendly.

Easy or not to leak

No, even under high pressure

No, even under high pressure

No, if without any pressure. Without presure is a must to this system


Medium and good for not super cold area

Super high cost since either colletor or tank is specially designed, good for only super cold climate area

Low cost but a lot of problem while using

Application Example
  • Balcony split system, which is wide-used in north China

  • Comecial projects with isolated commerical tank with collector arrays

  • Our panel in another Euro country, pressured and split system

  • Our collector in German house, pressured and split system
