flat solar collector 

integrative pressurized heat pipe solar water heater is a new type of solar water heater which adopts advanced heat pipe and all glass vacuum tube technology. highly efficient vacuum tube absorbs heat from sunlight and heat pipe transfers heat to the condensor end of itself. Condensor indirectly contacts with water through a copper cap and it boils water by releasing heat gained from vacuum tube. the available size of tank ranges from 150L to 250L..

Main features in the following:

1.High pressure storage tank(testing pressure=9 bar)

2.No vent and less heat loss as cmpared to low pressure model

3.Highly efficient heat pipe technology

4.No water introduced into vacuum tube

5.No sealing rubber is needed and hence no leaking problem

6.Easy plug-in installation

7.55mm CFC free PU foam insulation

8.Color galvanized steel out shell and stainless steel frame

Material of storage tank

Outer tank: 0.31mm thick galvanized/colorful steel

Inner Tank: 0.31mm thick SUS-304B food grade 

thick Insulation  55 mm thick Polyurethane foam
