solar water heater 200 liter, evacuated solar collector tube with CE certificate

This solar water heater introduced smart controller system and assistant electric heating system. The temperature sensor reflected temperature was low, smart controller could get the signal and made electric heater work to heat water. Hot water could be supplied in 24 hours even in rainy day.

The vacuum tube is the core of solar water heater,its structure is similar to an elongated thermos bottle which has vacuum space between inner and outer glass.On the surface of inner glass is coated with spectral selective absorbing painting using a special process for maximum absorption of the solar radiant energy .When the sunshines on the heater,the photons hit the coatings making the solar energy transform into the heat energy.The water absorbs heat from the outer coating to make the water temperature increase and the water density decrease.Hot water moves upward while the proportion of cold water drops.Hot water is always at the top.
