Features - High efficiency solar collector using heat pipes and evacuated tubes. - Able to be used in all climates. - Copper heat pipes are applied for rapid heat transfer. - Easy installation both on the roof and on the ground. - Applied for main water pressure. - 150mm pipe is applied in the inner tank for enough heat exchange. - Patented connection design isolates copper heat pipe from stainless steel inner tank, greatly reducing the damage caused by galvanic corrosion.[...]

Advantages - Highly efficient absorber, improving daily average efficiency up to 50%. - Withstand pressure of 0.6 MPa, can be connected directly with city water pipe. - No water exists in the evacuated tubes. The solar water heater can still work in the event of tubes breakage. - Simple structure, easy to assembly and install. - Can be used all year around in the cold climate. - Can be used together with auxiliary electric booster. - Automatically controlled. - Large-scale solar hot water[...]

Heat pump water heater is more efficient than electric resistance water heater, because the latter is used for moving heat from one place to another rather than generating the heat directly. The heat source is air outside or air in the basement where the house is located. Refrigerant fluids in the compressors transfer heat into an insulated storage tank. Heat pump water heaters are available with built-in water tanks called integral units, or add-ons to the existing hot water tanks. A heat pump water[...]
