Enamel-Lined Water Tank provides durable, corrosion-resistant, and hygienic hot water storage for pressurized solar water heaters. Ideal for homes, hotels, and commercial applications, it ensures safe, efficient, and long-lasting performance.

What is a Enamel-Lined Water Tank?

A pressurized enamel-lined water tank is designed to handle mains water pressure while providing a protective enamel coating inside the tank. Key features include:
Enamel Lining: High-temperature enamel coating prevents corrosion and scaling, extending tank lifespan.
Pressurized Design: Can directly handle water supply pressure, eliminating the need for auxiliary tanks or pumps.
Compatible with Solar Collectors: Works efficiently with flat plate or evacuated tube solar collectors.
Advantages of Pressurized Enamel-Lined Tanks
Corrosion Resistant: Protects the tank from rust and scaling, even under hard water conditions.
Safe and Hygienic: Food-grade enamel ensures clean and safe water.
Long Service Life: Typically lasts over 10 years, reducing replacement and maintenance costs.
Energy Efficient: Supports solar water heating systems to reduce electricity consumption.

Enamel Coated Water Tank Sales Points:

Insulation protection

CFC free polyurethane foam insulation is injected and surrounds the inner tank, filling the space between the inner tank and outer tank thus providing an exceptionally good heat retention barrier. This helps to reduce the energy cost by minimizing standby heat loss.

Electric Element

Low density Incoloy 800 immersion type element ensures long lasting performance with choice of various heat input (kw) offering different hot water recovery rates.

Anode Protection

Each tank is provided with a magnesium anode rod to protect it against corrosion, a process well proven in years of application.

Safety Protection

Each tank is provided with a pressure and temperature relief valve (P/T valve). It protects the tank against excessive pressure and temperature by releasing its contents safely to the floor trap via the drain pipe.

Wide Application

Water tank can be working standalone as an electric water heater, and it can also be working with solar collector, heat pump, gas, etc. like the following drawing:

Conclusion

The pressurized enamel-lined water tank is an essential component for reliable and efficient solar water heating systems.
Choosing Riwatt ensures safety, hygiene, durability, and energy efficiency for all your hot water needs.
