Closed Loop thermosyphon Solar Water Heater

详情

This is a closed loop thermosyphon solar water heater, this type system is a very economical and smart design, and very suitable for the hot areas. The tank is designed to be non-pressure, but we use the water from the copper coil inside the tank, so the water we use is pressurized and clean. The copper coil design makes the system be pressurized and stronger to resist rusty, so this kind of solar water heater is a best choice for the islands, hot areas and so on.
 

How it works:

The water within the coil is heated by passing through a body of very hot water thats been heated by the evacuated tube solar collectors, which means zero carbon emissions.

Water is heated directly within the evacuated tubes so there is no loss of energy. Heated water rises from the evacuated tubes into the storage cylinder displacing cooler water from the storage cylinder into the evacuated tubes to be heated.

The high temperature hot water generated by the evacuated tubes is stored within the insulated storage cylinder and is used to heat cold water instantly as it travels through a long copper coil within the storage cylinder. The stored heat of the thermal mass of the water in storage cylinder is exchanged to the water within the copper coil whenever a hot water tap is opened.

The pressure from the solar hot water system will be the same as your existing cold water pressure. This design is known as Solar Heat Exchange and is the most simple and reliable means available to capture the suns energy to heat water.
