Solar Energy Saving Heater

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
