Solar Energy Heaters

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
    a) Adopts the double-deck highly special hard glass tube of boron silicon
    b) Double-deck glass coaxial structure, intermediate layer releases the vacuum,
        maintain 5X10-2 Pa high vacuum for a long time while in charge offing
    c) Magnetism accuse of alternative absorption coating, AL/N/AL of sputter aluminum
        nitrogen aluminum alternative absorption coating olar radiation absorption
        rate 
        a≥93%, hot emissivity Β≤6%
    d) Long performance life: 15 years
    e) Endures climate feature: thermal efficiency is good in the whole year, can
        resist diameter 25mm hail
