SFH is the integrated pressurized solar water heater for domestic hot water that relies on the principle of thermosyphon to actively carry out natural circulation.
1. Product Description
SFH series are mainly 120L, 150L, 180L, 200L, 250L and 300L, to meet the needs of families in different regions.
It is especially suitable for high-latitude, cold and low temperature areas.

The solar collector collects light energy through the AL/N/AL/SS/CU coating,and converts light energy into heat then stores heat energy in the insulated water tank through a heat pipe, it relies on the thermosiphon principle for natural circulation heating of the water tank. The tank is enclosed pressurized which provides high pressure hot water.
2. Features and specifications
The natural circulation is actively carried out by the principle of thermosyphon, meanwhile pressure of the hot water is large and equal to the running water pressure.
The water tank is a pressure-bearing structure, with a test pressure of 0.9Mpa and a working pressure of 0.6Mpa. The inner tank material is food grade stainless steel SUS304, by fully automatic argon arc welding and double-sided argon gas protection. Inner tank can be used for more than 15 years.
The solar water tank is insulated with polyurethane having independent bubbles and foaming density,36KG/m3. resulting in less than 2 °C temperature drop of hot water within 12 hours.The temperature can maintain at 25 ° C for 24 hours, and it was not deformed for a long time.
The solar heat pipe is a phase change heat transfer design so the heat energy start-up is very fast. When heat pipe absorbs lignt under sunshine, the temperature can reach 222 ° C, resulting in providing high temperature hot water. The system uses double-layer solar vacuum tube with AL/N/AL/SS/CU coating, absorption rate >92%, reflectivity<8%. and service life 15 years.
1. SR609C controller: display water temperature, fully automatic control.
2. Electric heating: auxiliary heating equipment.
3. Magnesium rod: anode protection, protect the inner tank from corrosion.
4. Thermostatic valve: automatically control the outlet temperature according to the setting.
5.Water Pressure Rregulator valve: SFO-PR15 Water Pressure
Rregulator valve acts to keep the system pressure stable and
depressurized, which can avoid the influence of unstable water
supply pressure on the solar hot water system.
3. Product installation and case
Installation and use steps: select the installation location, assemble frames put water tank on the tank holder, install solar heat pipe, connect hot and cold water pipes, add water into tank then check if any water leakage, fix the system, daily use, regular inspection and maintenance.

4. Warranty and certificate
1st sunflower has passed certifications from different quality management systems and product testing institutions. such as ISO9000, CE, Solarkeymark, SRCC, BV, SGS, Watermark etc
Solar vacuum tube and bracket: 5 years
Water tank: 3 years
5. Packaging and transportation
The solar vacuum tube with heat pipe is packed in carton, and the carton is equipped with anti-pressure foam. We will add plywood cases extraly for package of goods under LCL shipment.
