As a seasoned manufacturer rooted in Hebei, China since 1998, Anping County Boli Hardware Wiremesh Products Factory has expanded its expertise to deliver high-performance solar thermal components. Our Compact Solar Hot Water Storage Tank is engineered for reliability, combining decades of metal fabrication experience with modern solar energy demands. Made from premium 304 stainless steel and available in capacities from 100L to 1000L, this tank is the ideal solution for residential and commercial solar water heating systems. It offers superior corrosion resistance, excellent heat retention, and a space-saving design that fits seamlessly into any installation.

Key Features & Technical Specifications

Premium 304 Stainless Steel Construction: The inner tank is fabricated from food-grade 304 stainless steel, ensuring long-term durability against rust and scale buildup. This material is widely recognized for its excellent resistance to high-temperature water and chlorides, making it suitable for both domestic and commercial applications.
Wide Capacity Range (100L – 1000L): Choose from standard sizes or request custom capacities to match your project requirements. Whether you need a compact 100L tank for a small family or a large 1000L unit for a hotel or industrial system, we have you covered.
High-Efficiency Insulation: The tank is wrapped with a thick layer of polyurethane foam (density 40-50 kg/m³) to minimize heat loss. Typical standby heat loss is less than 2°C per hour under standard conditions, ensuring hot water remains available for extended periods without constant reheating.
Compact & Space-Saving Design: Our tanks are designed with a slim profile to fit into tight spaces – attics, basements, utility rooms, or even outdoor installations with optional weatherproof casing. Vertical and horizontal orientations are available to accommodate different layouts.
Easy Installation & Maintenance: Pre-installed threaded ports (3/4" or 1" BSP) for inlet, outlet, auxiliary heater, temperature sensor, and pressure relief valve. The tank is equipped with a sacrificial magnesium anode rod (optional) for extra corrosion protection, extending service life beyond 10 years.
Versatile Compatibility: Works seamlessly with solar collectors, heat pumps, electric backup heaters, gas boilers, and district heating systems. The tank can be used as a primary storage or buffer vessel in closed-loop or open-loop systems.

Frequently Asked Questions (FAQ)

What is the warranty period for your solar storage tank? – We offer a standard 5-year warranty against manufacturing defects. Extended warranty options are available upon request.
Can the tank be used with a heat pump or gas boiler? – Yes, the tank is compatible with various heat sources. It features multiple ports for auxiliary heating elements, sensor probes, and connection to solar collectors, heat pumps, or boilers.
Is the 304 stainless steel suitable for high-chloride water? – 304 stainless steel offers good corrosion resistance in most domestic water conditions. For areas with very high chloride levels (e.g., coastal regions), we recommend upgrading to 316L stainless steel – available as a custom option.
Do you offer samples before bulk order? – Yes, sample orders are welcome. We can produce a single unit for testing and evaluation. The sample cost will be deducted from the first bulk order.
What is the minimum order quantity (MOQ)? – For standard sizes, our MOQ is 10 units. For custom sizes or special coatings, MOQ may be higher. Please contact our sales team for details.
How is the tank insulated? Does it work in cold climates? – The tank is insulated with high-density polyurethane foam (typically 50–80 mm thick). In cold climates, we recommend installing the tank indoors or in a heated space. For outdoor installations, an optional electric heating jacket or larger insulation thickness is available.
Can you provide certificates such as Solar Keymark or CE? – We can provide a factory test report and material certification. Certain international certifications can be arranged upon request, subject to additional costs and lead time. Please inquire with your specific requirements.
What payment terms do you accept? – We accept T/T (30% deposit, 70% before shipment), L/C at sight, and occasionally Western Union for small orders. Payment terms can be negotiated for long-term cooperation.
