solar water heater(integrated pressure)

         Integrated Pressurized Solar Water Heater1) The pipeline is made of red copper and conducted by heat transfer medium liquid; Water can't flow in the vacuum tubes and is operated when confined
2) Temperature preservation is equipped with standard electric water heater setting, automatic temperature control exchanger
3) The insulating layer uses polyurethane bulk bubble and has a good effect of temperature preservation
4) The product successfully carries out the installation of separation according to fabricating yard and is harmoniously blended with architecture
5) The equipments of separated solar water heater is composed by heat collector, storage tank, electric control device
6)Three-layer concentric borosilicate glass tubes
Vacuum heat-collecting tubes at high temperature with new triangle elements
Stable and reliable performance, well wind resistance
7) Meeting the requirement of washing clothes, abstersion and bathing
Specifications:
