Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer in the metal fabrication industry, now expanding our expertise to high-quality solar thermal components. Our Stainless Steel Hot Water Storage Tank for Solar Water Heating System (200L, 1.0MPa, Single Coil) is engineered to deliver reliable, efficient heat storage for residential and commercial solar thermal applications. With annual exports exceeding US$5 million and a global presence across North America, Europe, Asia, and Oceania, we bring decades of manufacturing precision to every tank.
Product Overview: This 200-liter single-coil storage tank is designed specifically for solar water heating systems, where the heat exchanger coil transfers solar-heated fluid to the domestic water. The tank is constructed from premium-grade stainless steel (SUS304/316L) to ensure long-term corrosion resistance and durability. Rated for a maximum working pressure of 1.0MPa, it meets the requirements of most pressurized solar hot water systems. The single-coil design optimizes heat transfer efficiency while maintaining a compact footprint.
Key Features & Technical Specifications
- High-Grade Stainless Steel Construction: Inner tank made of SUS304/316L stainless steel, resistant to rust and scaling, ensuring potable water safety.
- Single-Coil Heat Exchanger: Copper or stainless steel coil (optional) brazed to the tank wall for efficient heat transfer from solar collectors.
- High Pressure Rating: 1.0MPa (10 bar) working pressure, suitable for closed-loop pressurized systems.
- Effective Insulation: 50mm thick polyurethane foam insulation minimizes heat loss, maintaining water temperature for longer periods.
- Compact Design: 200-liter capacity in a vertical cylindrical shape, saving installation space.
- Easy Installation: Pre-fitted with multiple inlet/outlet ports (1 inch BSP female threads) for flexible plumbing connections.
- Optional Sacrificial Anode: Available upon request for additional corrosion protection in aggressive water conditions.
- Durable Outer Shell: Powder-coated steel or stainless steel outer jacket (optional) for protection against environmental elements.

Frequently Asked Questions
-
Q: Is this tank suitable for both pressurized and non-pressurized solar systems?
A: This tank is designed for pressurized closed-loop systems with a maximum working pressure of 1.0MPa. For non-pressurized open systems, we recommend our vented tank series. -
Q: What is the coil material? Can I choose copper or stainless steel?
A: The standard coil is made of copper, which offers excellent thermal conductivity. Stainless steel coils are available as an optional upgrade for environments with aggressive water chemistry. -
Q: Does the tank come with a magnesium anode rod?
A: A sacrificial anode rod is not included by default but can be added upon request to extend tank life in hard water areas. -
Q: What is the warranty period?
A: We offer a 5-year warranty against manufacturing defects for the inner tank. Warranty terms may vary by market; please contact our sales team for details. -
Q: Can I customize the tank size or connection ports?
A: Yes, we accept custom orders for different capacities (e.g., 150L, 300L) and port configurations. Minimum order quantity may apply. -
Q: How is the tank packaged for export?
A: Each tank is individually wrapped in protective foam and packed in a sturdy carton or wooden crate, suitable for sea freight. We can also provide palletized packaging for bulk orders. -
Q: What is the lead time for a standard 200L tank?
