Product Description

:
This is a pressurized system, with direct hot water storage tank and flat panel solar collector combined.We call it compact flat panel pressurized solar water heater.Open-loop systems are simply and fast way of water heating. They are best suited to warm climate regions because of operating directly with potable water. Open-loop systems are not recommended in regions where water quality is not good enough.

 

 

The enamel is coated inside the water tankWhich is of high corrosion resistance and of (EN12976 Standard)Great pressure bearing.Our Porcelain enamel tanks approved by CE, WATER MARK,ETL,WRAS,EN12977-3

The whole system approved by SOLAR KEYMARK Imported blue titanium absorber from Germany with
high absorptivity(95%) and low heat loss(5%)
High purity oxygen-free copper pipes as circulation
system with high thermal conductivity,anti-corrosion
pressure-bearing and longer service life.
Low-iron tempered solar glass as cover with 92% transmittance.
Our flat panel solar collector approved by SOLAR KEYMARK(EN12975 Standard)

How It Works:The system operates on the thermosiphon principle, It adopts the water-water circulation type. Heat adsorption membrane on the flat plate absorbs the solar heat to heat the water in the heat collector directly. deliver the heated water to the upper part of hot water storage tank via circulation pipe and unheated cold water in the lower part flows into the flat-type heat collector as supplementation.Then cold water is heated and delivered to the hot water storage tank.The circulation of water repeats till all water in the water tank is heated to the specified temperature.
