Unpressurized bearing solar water Heaters solar energy system for home
Feature:
1.Assistant tank can supply water automatically to the main water tank.
2.Direct heat exchange, heat transferred by three target vacuum tube rapidly.
3.solar water heater can fit with many kinds of roof style because of the rational designed bracket.Advantages:
1.Non-pressure and direct heat exchange make it less thermal loss.
2.Muitifunction:Bathing, washing.
3.Low operating cost, one time investment, and permanent benefit.
4.Long heat preservation house: 48-72 hours.
5.Installation and maintenance are easy.
Working principle:
This type is a compact non-pressurized system. The design of this type uses
the all-glass evacuated solar collector tubes as the heat absorb element. There
is a natural circulation system that works on a light absorption principle.
Depending on the different density between hot water and cold water, a
water flowing cycle is created in the tubes. Hot water flows automatically
upwards while the cold water flows down. The water in the storage tank will
be heated from this natural circulation.

This model is one of the most favorite on the international market.It was
scientifically and specially designed,is easy to install and operate.The
important point is it can feed water automatically and ensure the outlet water
as stable temperature,it will always provide you hot water.

Thermo siphon Solar Water Heater relies on the natural circulation of water
between the collector and the tank or heat exchanger. As water in the vacuum
tubes is heated, it rises naturally into the elevated tank while cooler heavier
water in the tank flows down to the bottom of the vacuum tubes, causing
circulation throughout the system. Greater height differential will result in
greater flow. Larger pipe, shorter runs, and gentle bends will make for an
adequate flow rate.
unpressurized All stainless steel solar water Heaters
How it works
The design of this type uses the all-glass evacuated solar collector tubes as the heat absorb element. The high vacuum degree of the clearance between the outer and inner tube can reduce the heat emission which caused by convection and conduction to a very low level. All-glass evacuated tube transfers sun energy into heat energy by high absorption rate and low emittance rate of layer films. Depend on the different density between the hot water and the cold water, a cycle created in the tube which hot water ascending and cold water descending status. Keeping natural circulation like this, the water in the tank will be heated.
Material
1. Inner tank: SUS304-2B stainless steel
2. Outer tank: Staineless steel/ colour coated steel
3. Insulation: Polyurethane
4. frame: stainless steel/galvanized steel/aluminium alloy
Characteristics
1. Beautiful appearance, steady structure, higher grads.
2. Inner and outside water tank shell all are welded by argon arc.
3. The tubes and frame are adjustable, power bearing is average, and can assure the vacuum tubes to use long time.
