JNYL-Non-pressurized solar water heaters

1.high absorption
2. low emittance rate of vacuum tube layer coating

Non-pressure solar water heater Characteristics

This type uses all-glasses evacuated tubes as the solar collector for absorbing and transferring the sun energy into heat energy.The high absorption and low emittance rate of vacuum tube layer coating is unique.Depending on the different density between hot water and cold water,the water flowing cycle is created in the tube.Hot water flows automatically upwards while the cold water flows down.The water in the storage tank will be heated from this natural circulation.
