Max working Pressure	1.0mPa	0.8mPa to 1.0mPa	Without any pressure, just something like MAX 0.2mPa
Tank and collector split or integrated	Split	Split	Integrated or split
Direct or Indirect system	Better indirect	Better indirect	Direct
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
Cost	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
