Features of Compact Pressurized solar water heater: The system is pressurized. Comfortable shower. Keep a constant temperature of water in the tank. Avoid the problem came from water level controller malfunction which could cause water flow out. Water wouldnt run in the tube, so the heat delivery efficiency wouldn`t be affected.

Solar water heaters are all-glass evacuated solar domestic water system combined with heat pipes. The selective coating in the inner cover of the evacuated tubes ensures high energy absorption and low heat radiance losses, which convert solar energy into heat energy and transfer to heat pipe by aluminum fin. The liquid in the heat pipe change into vapour by heating, the vapour goes up within the heat pipe. When heat is exchanging between the condenser end of the heat pipe with the water in the tank, it turns into liquid again, then comes down to the base of the heat pipe, this cycle continuously repeats as long as the sun shines. In this way the heat is transferred from heat pipe to the cold water in the tank. When the hot water can be obtained by injecting cold water from the bottom of the tank.

The solar water heater with heating pipe can be used in extremely cold areas due to there is no water in the glass tube. The inner tank of solar water heater system adopts the 1.2 mm imported SUS304 stainless steel and automatic welding technology which decrease the corrosion. 

Insulating layer: Foaming polyurethane, thickness: 50mm. Thermal conductivity: 0.022W/m. K. Inner tank: Stainless steel (SUS 304 2B or 316L stainless steel). Thickness: 1.2mm.

Hermosiphon solar collectors provides mains pressure pre-heating via a high efficiency copper coil heat exchanger located within the solar collector tank. The way in which the Mains Pressure solar collector heats water is the same as the Non pressure solar collector. Rather than using the water in the tank directly, as the Non pressure does, the type uses a 45~60 copper coil heat exchanger inside the tank which provides more than 1.2MP2P of heat transfer area. When water flows though the coil it absorbs heat from the water inside the solar collector tank.
