Pre Heated Sun Water Heater 20 Tubes

200L White Color Steel Coil Pre Heated Solar Water Heater 20 Tubes High Density Integral PU Insulation

Solar water heater Feature:
1) Designed to accept mains pressure cold water
2) Copper coil heat exchanger can be used as part of a closed or open loop system, providing heating to a main hot water tank
3) Freezing is of minimal concern
4) Reliable, efficient, twin-glass solar tubes
5) Superior heat preservation with 50 - 65mm polyurethane tank insulation
6) Outer tank material: stainless steel plate or powder coated color steel sheet
7) Inner tank material:
a) 0.5mm thick SUS304 food grade stainless steel plate
b) High purity copper for the heat exchanger coil
8) Frame material: 1.2mm thick all stainless steel or 1.5mm thick all Color sheet
9) Collectors may be connected in series to increase water heating capacity
10) Easy plug-in installation
11)Water supplier: supply the slowly vaporizing water in the tank in time
12) Ideal for commercial solar water heating applications

Working principle:
The vacuum tubes absorb the sunlight and turn it into the heat energy, heating the water in the tubes. Depend on the thermo siphon principle, the hot water from the tubes goes into water tank, while the cold water from the tank goes down to the tubes.
People do not use the water from the water tank directly. The cold water comes into the copper exchanger, be heated, then goes out from other side for people use.

Competitive Advantage:

1. We get instant clean and pressure hot water from copper coil outlet;

2. Simple structure with very easy installation and pipeline connection;

3. With copper coil exchanger we do not need to locate the solar water heater at the house top;

4. PASSION argon-arc welding and in-house testing ensures a long lasting storage tank without any leakage problem;

5. PASSION makes a high-density integral PU insulation for the tank with heat preservation as long as 72~80 hours;

6. The solar vacuum tube is made of high borosilicate glass with stable performance and no blasting problem for 15 years;

7. The support frame is designed for slope and flat roof installation, aluminum alloy with stainless fastener has no rusty problem;

8. PASSION pre-heat solar water heater can be equipped with assistant tank and electric heater to make an automatic-operating system;

9. We install sample solar water heater for every order before delivery to ensure no mistakes or missing parts for customers.
