1. Product Description
SFFU is a household integrated non-pressure solar water heater that uses solar flat panel collectors to absorb solar heating water.
The flat plate solar collector absorbs light energy through the coating and converts the light energy into heat energy stored in the insulated water tank. It relies on the thermosiphon principle to naturally circulate the water tank. Open water tanks are not subjected to pressure and are also known as low-pressure solar water heaters.
2. Features and Specifications
Actively carry out natural circulation by relying on the principle of thermosyphon, 100% solar energy, and no running cost.
Hot water draining out from tank by gravity. Water pressure is determined by the difference between the installed height of the solar tank and the height of the hot water outlet at user side.
The inner tank is made of food grade SUSU304. It is fully automatic argon arc welding and double-sided argon gas protection to effectively prevent the surface from being oxidized. Strict welding process control measures to better protect the crystal structure of SUS304 from damage. The inner tank has a service of life 15 years more.

The insulation layer of solar tank is polyurethane having independent bubbles with foaming density 36KG/m⊃3;, and the temperature drop of hot water within 12H is less than 2 °C. Under the ambient temperature of 25 ° C, the temperature is kept for 24 hours, and it will not deform for a long time.
Automatically replenish the amount of water in the tank.
Display water temperature and water level, fully automatic control.
