Description:
1.Non-pressurized solar water heater is such kind of a most economical system with high efficiency at the same time. It works depending on the gravity of water, so it's much better to be installed on the slope or flat roof as top as possible to get enough hydraulic pressure.
2.A simple assistant tank can be equipped for tap water refill automatically or with an intelligent controller to control the start up of auxiliary heating device at the same time.
Inner tank:food grade stainless steel SUS304-2B
Outer tank:Galvanized color steel/stainless steel/PVDF
Insulation :50mm polyurethane foam for 72hrs heat preservation
Collector :Vacuum tube painted by magnetron sputtering selective
Bracket:Galvanized steel/stainless steel/aluminum alloy
Install instruction:
1. Non-pressurized solar water heater of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required. They are simple, economic and practical.
2. As the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward.
3. When cold water in evacuated tubes is heated, it becaomes lighter and goes to the water tank, while cold water in the tank goes down to the evacuated tubes
4. Through this circulation, the cold water in the water tank will be gradually heated.
Applications:
Domestic hot water for shower, washing
Competitive Advantage:
1.Features:
(1). Cheap and reliable solution, Simple structures, Easy installation.
(2). High efficiency of heating,water heated by sun light directly.
(3). Withstands water pressure no more than 0.1MPa.
(4). Operated without any power supplying.
(5). Electric heater can be used as back-up in rainy days.
(6). Hot water can be used directly, or can be used as a pre-heated.
(7). Water flow in the vacuum tubes and is operated when confined.
(8). Tank is equipped with electric water heater setting, automatic temperature controller(optional ).
(9). The insulating layer uses polyurethane bulk bubble,keep hot water 72 hours.
2.How to choose:
Choose the item according to the capacity, and choose the capacity according to the people quantity
in your family, one adult shower need about 50 L water. Normally,50 liters is only used for one person's shower.
