Solar water heater with U pipe solar collector

Evacuated tubes convert solar energy into heat energy, that is transferred to U pipe by an aluminum fin with high solar energy absorption and low heat radiance loss,Liquid (antifreezing liquid or water) in the Upipe heats up,and the U pipe conducts thermal energy to the water inside the storage tank ditectly (or through internal copper coil),With a testing pressure of 1.2 MPa, Working pressure is 0.6MPa U pipe collectorfeatures The test pressure reach to 1.2 MPa, can be connected directly with city tap waterNo water inside the evacuated tubes, the system can still in service even with several tubes breakage.Can be used all year round in the cold climate.Using U pipe solar collector, has better appearance.
