Solar Water Heater Work Principle: The key of compact heat pipe pressure solar water heater is heat pipe, The heat pipe is hollow with the space inside evacuated, much the same as the solar tube. In this case insulation is not the goal, but rather to alter the state of the liquid inside. Inside the heat pipe is a small quantity of purified water and some special additives. At sea level water boils at 100oC (212oF), but if you climb to the top of a mountain the boiling temperature will be less that 100oC (212oF). This is due to the difference in air pressure.
based on this principle of water boiling at a lower temperature with decreased air pressure, by evacuating the heat pipe, we can achieve the same result. The heat pipes used in AP solar collectors have a boiling point of only 30oC (86oF). So when the heat pipe is heated above 30oC (86oF) the water vaporizes. This va pour rapidly rises to the top of the heat pipe transferring heat. As the heat is lost at the condenser (top), the va pour condenses to form a liquid (water) and returns to the bottom of the heat pipe to once again repeat the process.
The top of heat pipe is pluged into the water tank, so the cold water inside the tank can get heat from heat pipe, and become hot water. Because the water tank is close, so it can endure 0.6Mpa(6 bar), when the tap go into the water tank from the bottom inlet, the hot water is out from the top outlet, just like the electric water heater.
