The 200L Indirect Solar Water Heater System is a high-performance solution tailored for cold climates. This system consists of several key components: a 200L hot water storage tank, solar heat pipe collectors, a pump station, and an expansion vessel. The system utilizes glycol fluid circulation to transfer heat from the solar collectors to the water tank via a coil heat exchanger, ensuring efficient heating even in freezing temperatures.
The indirect system is perfect for areas with harsh winters, as the glycol fluid prevents freezing inside the collectors. The system operates using an intelligent solar controller, which automatically adjusts the circulation based on the temperature difference between the collectors and the water tank. The solar heat pipe collectors are highly efficient, ensuring minimal heat loss and a consistent supply of hot water.
The Indirect Solar Water Heater revolutionizes renewable energy-based water heating through its advanced closed-loop technology. Engineered for regions with harsh winters, this system employs a high-efficiency heat exchanger to transfer thermal energy from solar collectors to your water supply without direct contact. The dual-circuit design utilizes a non-toxic, ethylene glycol-based heat transfer fluid that circulates between roof-mounted collectors and an insulated 200L stainless steel storage tank. Certified to withstand pressures up to 6 bar, the A1 maintains stable performance across temperature extremes from -35°C to 95°C. Its compatibility with most existing plumbing systems allows for hassle-free retrofitting, while the corrosion-resistant construction ensures minimal maintenance over its 15-year lifespan.

· Dual-Coil Heat Exchanger: Copper primary coil extracts solar heat, while the secondary coil interfaces with domestic water, achieving 85% thermal transfer efficiency.
· Multi-Layer Insulation: Features 50mm polyurethane foam with aluminum cladding, reducing nightly heat loss to under 15%.
· Adaptive Pump Control: The SC-1000 controller automatically adjusts flow rates based on temperature differentials (ΔT ≥ 8°C activation).
· Cross-Climate Valving: Includes pressure-relief valves and automatic air vents for system protection during thermal expansion.
· Solar-Ready Ports: Pre-installed connections for photovoltaic panels to power the circulation pump sustainably.
1. Pump will start circulation when temperature difference between solar collector and water tank reaches the set value.
2. Pump will stop circulation once the temperature difference lower than set value.
3. The circulation pump makes heat-conducting liquid circulate automatically
4. The heat-conducting liquid transfers heat to the water tank by a coil heat exchanger.
5. The solar thermal panel will collect energy from sunlight to heat water; there is electric heating element inside water tank, for backup in cloudy or rainy days.
It sets new standards in smart solar thermal management with its AI-driven optimization platform. This 300L capacity system combines phase-change material technology with real-time weather adaptation, achieving 92% annual solar fraction in temperate zones. The proprietary Nano-Gel storage medium solidifies at 58°C, storing 40% more latent heat than conventional water tanks. Integrated IoT capabilities enable remote diagnostics and predictive maintenance alerts through the SolarConnect Pro mobile app. Meeting EN 12975 and ASHRAE 90.2 certifications, it features a ultra-low standby heat loss rate of 1.2°C per day, making it perfect for eco-conscious commercial establishments.
· Dynamic Flow Control: Magnetohydrodynamic pump adjusts velocity from 0.5-4.0 L/min without moving parts.
· Triple-Glazed Collectors: 94% solar absorptance rating with anti-reflective coating for dawn/dusk performance.
· Leakage Sentinel System: Conductivity sensors detect 0.5ml/min leaks, triggering automatic isolation valves.
· Demand Forecasting: Machine learning algorithms analyze usage patterns to preheat water before peak hours.
· Modular Expansion: Connect up to 3 additional storage tanks for large-scale hotel/apartment deployments.
· University Dormitories: Central heating for 50+ student showers with load-balancing between modules.
· Swimming Centers: Maintains pool water at 28°C year-round through heat exchanger integration.
· Dairy Farms: Provides 65°C sanitization water for milking equipment sterilization.
1. What cybersecurity measures protect the IoT system?
256-bit AES encryption with biweekly OTA security updates ensure network protection.
2. Can phase-change materials be replaced?
The Nano-Gel matrix lasts 10+ years; factory servicing is required every 7 years.
3. How does it handle hard water areas?
The closed-loop design isolates domestic water from collectors, preventing limescale accumulation.
