Features:
1) Working principle of high pressure solar heater: utilizes the alternative
absorption coating on the inner surface of the vacuum tube, from the
high-temperature environment super-conduction tubes lead the heat to the
water tank, and produces hot water
2) Easy to use, also convenient to install
3) Can be put in the courtyard, on the roof or balcony
4) Inlet water hole connects to the tap water, and the outlet hole connects to
the tap water, and the outlet hole produces pressure hot water directly
5) Working principle of low pressure solar heater: adopts the alternative
absorption coating to absorb the solar energy, heat the water in the vacuum
tube directly, through the cold hot water convection, changes the solar
energy into heat energy to store in the water tank
