PRESSURIZED HEAT PIPE
When vacuum tube absorb solar energy and heat the heat pipe ,the working fluid vaporizes and rise to the top of the heat pipe condenser, when heat pipe condenser meet cold water and cool down, the working fluid will fluidity and return to the bottom of the heat pipe, so once and once again to repeat this process.
The pressurized solar water heater system has an inner tank, which is made using 1.2mm SUS316 stainless steel using the latest automatic welding technology throughout the welding process. The tank has been high pressure tested to 10 bar.
The heat pipe evacuation tube consists of a copper heat pipe and glass evacuation tube. The glass evacuation tubes and the heat pipe are the key components of the Sustainable Energy Technologies solar thermal water heaters.
Each evacuation tube consists of two glass tubes. The outer tube is made of extremely strong transparent borosilicate glass, and is able to resist impact from hailstones up to 25mm in diameter.
- Available Capacities: 200Litres, 250Litres & 300Litres

PRESSURIZED PRE-HEATED
The vacuum tubes absorb the sun’s rays and turn the rays into energy, heating the water in the tubes. As the temperature of the water is rising, The density turns slightly, then the hot water in the tubes floats into the tank, and the cold water in the tank goes down to the tubes. Keeping natural cycling like this, the water in the tank will be heated.
The vacuum tubes heat the water in the tank, but the users do not use the water in it directly. The cold water comes into the exchanger from one side and the hot water heated by the exchanger, and then the hot water comes out from the other side for use. The Solar Water heater tank is a non-pressurized tank, and has an opening to the ambient atmosphere. Solar water heater tank should always be filled with water to avoid damage caused by dry high temperature working conditions. The stainless steel our use belong to food grade, and SUS 304 & SUS 316 have better corrosion resistance.

NON-PRESSURIZED
The vacuum tubes trap incident sun rays, and convert it to heat inside the inner tube. Water, now being heated its temperature rises, density changes, and hot water sections rise through the tube to the top of the tank, while cold water from the bottom of tank replaces it in the tube, to start the cycle again. This natural cycling of water driven by temperature difference keeps water hot when stored in an insulated tank.
