Features:
1) Highly efficient absorber of high performance with daily average efficiency
over50%
2) Withstand pressure of 0.6 MPa, can be connected directly with city water pipe
3) The storage tank and the heat pipe are metallic sealed
4) No water inside the evacuated tubes; the solar water heater can still in
service even with several tubes breakage
5) Highly efficient insulation with polyurethane foam
6) Simple structure, easy to assembly and install, diffuse flat plate reflector
can be assembled easily with its module structure
7) Can be used all year round in the cold climate
8) Can be used together with auxiliary electric/gas/oil heating decive
9) More and more used for radiator and floor heating.
9) Automatically controlled
10) Large-scale solar hot water system can be installed either with parallel or
series connections
