Product Overview

Pump-free Natural Circulation Solar Domestic Hot Water Systems

Pump-free Solar Water Heater

We are dedicated to the design, research and development, and installation of Eco-friendly clean energy hot water systems. This pump-free water heater is a high-efficiency solution with CE, ISO9001, and CCC certificates, suitable for residential and commercial use in hospitals, hotels, and schools.

Utilizing open water tank heat storage and a closed coil for heat exchange, this system features 20-second rapid heat exchange technology. Hot water is available quickly with municipal-level pressure, ensuring a consistent temperature without sudden fluctuations.

🌀 Coil Heat Exchange

Uses RHEs reverse heat exchange technology. Pressurized water is fresh and free from secondary pollution without needing a booster pump.

⏱️ 20s Rapid Exchange

Cold water turns into hot water in just 20 seconds. Maintains fresh water quality suitable for kitchen use.

💎 Titanium Coating

Super blue titanium coating ensures high absorption and low reflection for maximum energy efficiency.

🏗️ Modular Design

Expandable water tank design allows for scaling up based on hot water demand.
