Solar Thermal Water Heater (Tube Type)
Key Highlights
High Heat Collection Efficiency
Heat pipe vacuum tube design provides fast heat transfer and high solar energy utilization.
Corrosion Resistance & Long Service Life
Fully enclosed flow channel design helps reduce leakage risk and supports long-term outdoor operation.
Anti-Freezing & Anti-Burst Design
Water does not directly circulate inside the vacuum tubes, helping reduce freezing risk in winter and tube damage risk in summer.
Suitable for Centralized Hot Water Projects
Ideal for hotels, schools, hospitals, swimming pools, dormitories, and other centralized hot water systems.
Multiple Models Available
Available models include HPC318, HPC395, and HPC472, with 20 / 25 / 30 vacuum tubes for different capacity requirements.
Customizable Structure
Collector size, structure, and connection interfaces can be customized according to project needs.
High Operating Temperature
Maximum working temperature up to 120°C, suitable for engineering hot water systems.
Easy Installation & Maintenance
Standard interface design makes it convenient to connect with water tanks, circulation pumps, and control systems.
