Heat-pump Water Heater suppliers 1. Product Name锛?/strong> CLOSED LOOP (INDIRECT) SYSTEM
2.Product Description:
This is a pressurized system, with jacketed tank and flat panel solar collector combined.We call it compact flat panel pressurized solar water heater.
This closed loop system can prevent freezing and scale. Heated glycol-water mixture solution from the collector flows into the tank鈥檚 jacketed shell heat-exchanger and then returns to the collector after heating up the domestic water.
3.Product Features:
The enamel is coated inside the water tank The whole system approved by SOLAR KEYMARK Imported blue titanium absorber from Germany with
Which is of high corrosion resistance and of (EN12976 Standard) high absorptivity(95%) and low heat loss(5%).
Great pressure bearing. High purity oxygen-free copper pipes as circulation
Our Porcelain enamel tanks approved by CE銆?system with high thermal conductivity,anti-corrosion
WATER MARK銆丒TL銆乄RAS銆丒N12977-3 pressure-bearing and longer service life.
Low-iron tempered solar glass as cover with 92% transmittance.

6. How It Works:
The system operates on the thermosiphon principle, meaning that heat transfer occurs entirely by means of natural convection, without pumps and control units. The solar fluid heated in the collector rises and transfers heat through a highly efficient jacketed shell. High-selectivity harp absorbers are used to guarantee the highest possible solar yield in this system.
