Flat Panel Solar Water Heater

I. Product Overview

The flat plate integrated solar water heater is a high-end solar thermal system that combines energy efficiency, operational safety, user comfort, and modern aesthetics into a single integrated solution. The system adopts a streamlined triangular structure with a stable center of gravity, while the support frame features rhythmic variations in thickness, delivering both mechanical strength and visual harmony.

Finished in a refined space-grey tone, the system conveys a calm, elegant, and contemporary appearance that integrates naturally into a wide range of architectural styles. When installed on rooftops, it remains visually balanced and non-intrusive, reflecting a modern sense of technology and quality living.

Functionally, the system significantly outperforms conventional solar water heaters. It delivers high water output, strong pressure, and balanced hot and cold water supply, eliminating temperature fluctuation during use. It relies entirely on clean solar energy for primary heating, resulting in low operating costs, long service life, and a sustainable hot water solution.

II. Core Technical Characteristics

The system utilizes an innovative enamel-jacket thermal storage structure. A heat transfer medium circulates naturally between the flat plate collector and the jacket, enabling efficient heat exchange. The collector frame is manufactured from electrophoretic aluminum alloy profiles, while the absorber surface is treated with a high-selectivity coating achieving solar absorptance above 95%, ensuring efficient solar energy capture throughout the day.

The support frame is formed from hot-dip galvanized steel sheets and treated with a protective surface coating, delivering excellent corrosion resistance and mechanical strength for long-term outdoor operation.

III. Product Features

· Pressurized Top-Feed Operation:
Water pressure is supplied directly by the municipal network, eliminating the need for booster pumps or manual water filling while delivering strong and consistent water flow.

· Integrated Modular Design:
The collector and tank are functionally separated but structurally integrated, allowing easy installation and stable rooftop placement.

· Constant Temperature and Pressure:
Balanced hot and cold water pressure combined with intelligent temperature control ensures stable and comfortable water temperature.

· Intelligent Auxiliary Heating:
An auxiliary electric heater automatically supports the system during extended periods of low solar radiation, ensuring 24-hour hot water availability.

· Visual Control Interface:
An indoor controller displays water temperature and system status in real time for user convenience.

IV. Working Principle

The system operates based on the thermosiphon circulation principle. Solar radiation heats the fluid inside the flat plate collector, reducing its density and causing it to rise into the jacket of the storage tank, where heat is transferred to the domestic water. The cooled fluid then flows back to the collector, forming a continuous natural circulation loop.

The process requires no pumps or mechanical drive, ensuring silent, energy-efficient operation. The auxiliary electric heater functions only when solar energy is insufficient, guaranteeing uninterrupted hot water supply.

V. Product Advantages

The system offers comprehensive advantages in configuration flexibility, performance, safety, and ease of use:

· Installation angles of 0°, 25°, and 45° adapt to different geographic and architectural conditions.

· Tank capacities of 150 L, 200 L, and 300 L suit households of different sizes.

· Optional enamel or stainless steel tanks accommodate various water quality conditions.

· Modular connection allows expansion for higher demand.

· Water and electricity are completely separated to ensure operational safety.

· Dual-layer corrosion protection ensures long service life.

· High-efficiency selective coating reduces electricity consumption by up to 80% compared with electric heaters.

· Pre-assembled components and natural circulation reduce installation and maintenance complexity.

VI. Conclusion

The flat plate integrated solar water heater represents a modern solar thermal solution that blends technology, aesthetics, and sustainability. With its efficient performance, robust construction, and user-oriented design, it provides a reliable and environmentally responsible hot water system for contemporary households.
