Technical Principle

This product operates based on the thermal principle and belongs to a passive solar system. The metal heat-absorbing plates inside the flat collector are coated with selective absorption coatings, which efficiently absorb solar radiation and convert it into thermal energy. The heat is conducted to the copper tube flow channels closely connected to the heat-absorbing plates, heating the medium inside the tubes. The heated medium has a reduced density and naturally rises, flowing through the upper circulation pipe into the stainless steel 316 inner tank water tank; the cooler medium flows through the lower circulation pipe into the bottom of the collector, forming a natural circulation. This repeated circulation gradually heats up all the water in the water tank. As a pressurized system， the water tank is directly connected to the tap water, and the water pressure is equivalent to that of the water supply network, meeting the demand for simultaneous use by multiple users. 

Factory Advantages

1. Professional manufacturing experience: With 15 years of experience in manufacturing solar water heaters, specializing in pressurized flat plate solar technology, the company has mature and stable techniques. 

2. Fully automated production line: We have introduced an automated laminating production line for flat plate collectors, a stainless steel inner tank welding center, and polyurethane foaming equipment, ensuring product accuracy and consistency in quality. 

3. Strict quality control system: Implementing full-process quality management including incoming material inspection, process control, and finished product testing. Every 200L flat-panel solar water heater undergoes strict pressure testing and corrosion resistance tests before leaving the factory. 

4. Customization service capability: Supports OEM/ODM customization. We can provide personalized services such as different specifications of stainless steel 304 shell surface treatment and logo printing to meet various market demands. 

Product Advantages

1. 316 Inner Shell, Super Strong Corrosion Resistance: The 316 inner shell contains molybdenum, which has a better resistance to chloride ion corrosion than the ordinary 304. It is particularly suitable for coastal areas and scenarios with high water quality requirements, and its service life exceeds 15 years. 

2. 304 shell, enduringly fresh: The stainless steel 304 shell has strong weather resistance. Its brushed surface is fingerprint-resistant and easy to clean. It won't fade or rust even under sun exposure or rain, and seamlessly blends with the architectural appearance. 

3. High-pressure containment, refreshing shower: The pressure-containment design directly connects to the tap water, ensuring strong and stable water pressure. No booster pump is needed, meeting the water demand for multiple users simultaneously. 

4. High-efficiency heat collection, usable even on cloudy days: The flat plate collector is coated with black chrome/blue film, with an absorption rate of up to 95%. Even on cloudy days, it can still efficiently generate heat, providing stable hot water supply throughout the year. 

5. Excellent insulation, energy saving and cost reduction: A 55mm polyurethane integral foaming insulation layer, with a temperature drop of less than 5℃ within 24 hours, significantly reducing electricity bills and achieving remarkable energy-saving effects. 

Application Scenarios

1. Residential Homes: The 200L flat-panel solar water heater can meet the daily bathing and kitchen hot water needs of a 4-6 person household. 

2. Villa/Dwelling House: The flat collector can be integrated with the building design, and is equipped with a stainless steel 304 casing, presenting a beautiful and elegant appearance. 

3. Small-scale businesses: Hot water supply for places such as restaurants, barber shops, and small hotels, reducing operating costs. 

4. Coastal areas: The excellent corrosion resistance of the stainless steel 316 inner liner makes it particularly suitable for use in high-salt spray environments. 

Certification

Our pressure-type flat-panel solar water heaters have obtained multiple international certifications, ensuring their high quality and reliability. 

1. EU Solar Keymark Certification: Compliant with European Standards 

2. SRCC Certification: Applicable to the North American market 

3. CE certification: Compliant with EU safety requirements 

4. ISO 9001: International Quality Management System Certification 

Installation Instructions

1. Installation Location

The collector should face due south or 10-15 degrees westward. There should be no obstructions around to ensure full sunlight throughout the year. 

2. Roof Load Capacity

After filling with water, the total weight of this machine is approximately 320 kg. Before installation, confirm the roof's load-bearing capacity and reinforce it if necessary. 

3. Support fixation

The support must be securely fixed using expansion bolts, and the wind resistance grade should be above level 8. 

4. Pipeline insulation

The outdoor pipelines are covered with 20mm or more insulation cotton, and waterproof tape is wound on the outer layer. In cold regions, heating tapes are also installed. 

5. Pressure relief valve installation

A safety pressure relief valve must be installed. The drainage pipe should be led to a floor drain. It is strictly prohibited to block it or make any unauthorized modifications. 

6. Professional Installation

This involves high-altitude work and waterway connections. It must be installed and debugged by professional personnel to ensure safety.
