Solar Water Tank

Foshan Legend Solar Water Tank is designed for efficient thermal energy storage in residential and commercial solar water heating applications. Manufactured with high-quality stainless steel, this tank provides reliable hot water storage, effective heat exchange and flexible configuration options for different project requirements.

As an important component of solar thermal equipment, the tank stores heated water and helps maintain a stable hot water supply when solar energy availability changes. With customized heating coils, durable inner tank materials and effective thermal insulation, Legend provides dependable solar water storage solutions for residential buildings, hotels, commercial facilities and customized heating projects.

Product Features

Efficient Heat Exchange Performance

The solar water tank is equipped with an upgraded heating coil design to support efficient thermal transfer between the heat source and stored water. Different coil configurations are available to accommodate various heating requirements, helping improve heat exchange performance and equipment compatibility.

Customers can choose flat coils, wave coils or refrigerant-related coils according to their project requirements and heating equipment configuration.

Durable Stainless Steel Inner Tank

The inner tank is available in SUS304, SUS316L and Duplex 2205 stainless steel. These materials offer different corrosion resistance characteristics and can be selected according to water quality, operating conditions and application requirements.

The stainless steel construction provides a durable storage environment while supporting long-term use in residential and commercial hot water applications.

Effective Thermal Insulation

The tank features a foamed insulation layer designed to reduce heat loss during water storage. Good insulation performance helps maintain the temperature of stored hot water, reduces unnecessary heat dissipation and supports more efficient utilization of collected solar energy.

Reliable Pressure Resistance

Each tank is designed for a standard working pressure of 6 bar and undergoes hydraulic testing at 10 bar before delivery. Additional leakage testing helps inspect welding seams, tank connections and sealing performance to reduce potential leakage risks.
