3000liter central solar water heating system

3000liter central solar water heating system for large scale hot water projects could meet customer demand in supplying 3000liter hot water each day. It includesa 3000liter hot water storage tank, and evacuated tube solar collectors are connected by pipelines together. The whole solar water heating system is installed on the top of building. When solar collector gnerate heat , the circulation pump starts. Cold water goes through solar collector arrays, become hot water flow back to water tank. After long time circulation, the storage water tank is full of hot water . The central solar heating system will supply hot water at constant pressure.

Features


1. High-Efficiency Solar Collectors


o Made of premium anti-reflective glass and selective coating tubes, the vacuum tube collectors achieve over 92% solar absorption efficiency, even in low-light environments.

o Corrosion-resistant aluminum frames ensure longevity in harsh weather.


2. Large-Capacity Storage Tank


o The 3000L stainless-steel tank features dual-layer insulation (polyurethane foam + aluminum casing), maintaining water temperature for 72+ hours.

o Advanced heat exchanger technology ensures rapid thermal transfer and minimal energy loss.


3. Smart Control System


o An IoT-enabled controller allows real-time monitoring of water temperature, pressure, and system performance via mobile devices.

o Auto-protection modes prevent overheating, freezing, or pressure fluctuations.


4. Durable & Low Maintenance


o All-welded, leak-proof construction with a 15-year lifespan for critical components.

o Self-cleaning collectors reduce dust accumulation and maintenance costs.


5. Energy Savings & ROI


o Reduces reliance on fossil fuels, slashing operational costs by 60–80%.

o Payback period as short as 3–5 years, depending on local energy prices.

FAQ


Q1: What is the installation space requirement?

A: The system requires approximately 25–30 m² of unshaded rooftop or ground space for solar collectors and a 2 m² area for the storage tank. Custom layouts are available for space-constrained sites.


Q2: How does it perform in cloudy or cold climates?

A: The vacuum tube collectors operate efficiently in temperatures as low as -30°C and can absorb diffuse sunlight on cloudy days. An optional backup heater ensures uninterrupted supply during extreme weather.


Q3: What maintenance is required?

A: Annual inspections are recommended to clean dust from collectors and check insulation integrity. The system’s self-diagnostic alerts simplify troubleshooting.


Q4: Can it integrate with existing water heaters?

A: Yes, the system supports hybrid configurations with gas, electric, or heat pump backups for seamless operation.


Q5: What is the warranty period?

A: A 5-year warranty covers the storage tank and controllers, with a 2-year warranty on pumps and sensors. Extended warranties are available upon request.


Q6: Are customized designs possible?

A: Absolutely. We offer tailored solutions for capacity, pressure ratings, and smart controls to meet specific project needs.



The 3000L Central Solar Water Heating System combines innovation, reliability, and sustainability, making it a cost-effective choice for global clients seeking to reduce energy expenses and environmental impact. With scalable designs and proven performance, it stands as a future-proof investment for businesses and communities worldwide.
