1.pressure system：It can apply water automatically and water dropping with pressure , comfortable to shower

2.resistance to corrosion in inner tank：Particular welding construction and techniques avoid corrosion ,also make the long service

3.heat collecting efficiency ：It adopts heat pipe collector ,which have no scale , higher heat efficiency ,more stably for system

4.heat collector can be separated：Heat collector and tank can be packed separately , which is easy to pack
