Pressurized Solar Water Heater

Advantages and benefits
Easy installation and low maintenance cost of heat pipes and vacuum tubes,

High-quality stainless steel for the inner tank to continuously maintain a good water quality.

Stable operating without tube scaling or pipe explosion risk.

Fast system starting, high energy yield and low heat loss.

Strong capability of anti-freezing that is available for applications in low temperature area.

Pressurized system operating which is suitable for different installation methods.

The selective coating on the inner cover of the vacuum tubes converts solar energy and transfers heat to the heat pipes by aluminum fins. The liquid in the heat pipe changes into vapor which rises to the condenser. Then the heat passes through the heat exchanger, the water inside of water tank is being heated, and the vapor becomes liquid, returning to the bottom of the heat pipe. This transference of heat creates a continuous circulation as long as the heat pipe vacuum tube collector is heated by sun.

Heat is transferred by liquid to the water tank and heat the water efficiently. In addition, heat pipe vacuum tubes is highly freezing resistance, which ensures higher efficiency in cold areas.
