Product Overview


The RNE-VCA Series High Efficiency Solar Pool Heater is a cutting-edge solution designed to harness solar energy for eco-friendly pool heating. Engineered with advanced vacuum tube technology, this system efficiently absorbs solar radiation, converting it into thermal energy to maintain optimal pool temperatures year-round. Ideal for residential and commercial pools, the RNE-VCA series offers six models (RNE-VCA-12 to RNE-VCA-50) with varying tube quantities and absorption areas (1.73–7.08 m²), ensuring scalability for different pool sizes and heating requirements. By eliminating reliance on electric or gas heaters, it reduces energy costs by up to 80% while minimizing environmental impact.


Key components include high-quality borosilicate glass vacuum tubes (58mm diameter, 1800mm length) that resist corrosion and extreme temperatures, combined with a robust stainless steel manifold for reliable performance. The system integrates seamlessly with existing pool filtration systems, requiring minimal modifications for installation.

Features


Vacuum Tube Technology for Maximum Efficiency

The RNE-VCA series employs evacuated tube collectors with a selective coating that absorbs both short and long-wavelength solar radiation. Each tube’s vacuum-sealed design minimizes heat loss, achieving thermal efficiency of up to 85% even on cloudy days. This technology outperforms traditional flat-plate collectors by 30–50%, making it suitable for regions with inconsistent sunlight.


Frost Resistance and Durability

Constructed with UV-stabilized materials and anti-freeze protection, the system operates reliably in temperatures as low as -20°C. The borosilicate glass tubes withstand hail impacts (up to 25mm diameter) and chemical exposure from pool chlorination, ensuring a lifespan of over 20 years.


Customizable Sizing and Flexibility

With six models available, users can select the ideal configuration based on pool size and climate. For example:

RNE-VCA-12 (12 tubes, 1.73 m²) suits small pools (up to 100 ft²).

RNE-VCA-50 (50 tubes, 7.08 m²) is optimal for large commercial pools (400–500 ft²).

The modular design allows easy expansion, and the compact structure fits rooftop or ground-mounted installations, maximizing space efficiency.


Low Maintenance and Cost-Effective Operation

The system requires minimal upkeep—periodic cleaning of tubes and checking for debris ensures peak performance. Unlike gas heaters, there are no fuel costs, and the payback period typically ranges from 1–3 years, depending on usage. A built-in differential temperature controller automatically regulates water flow, optimizing energy consumption.


High-Quality Materials and Safety

All components meet international standards (e.g., CE certification) and are manufactured using corrosion-resistant stainless steel and food-grade polymers. The system includes pressure relief valves and anti-freeze protection, ensuring safe operation in all weather conditions.

Applications


Residential Pools

Extend your swimming season by 3–6 months with consistent heating. The RNE-VCA series is compatible with in-ground and above-ground pools, reducing reliance on expensive electric heat pumps. For example, a 15’x30’ pool can be heated by 2–5°C daily using the RNE-VCA-24 model.


Commercial and Public Pools

Hotels, resorts, and community centers benefit from energy savings and scalable heating. The RNE-VCA-50 model, with 7.08 m² absorption area, efficiently heats large pools while complying with sustainability mandates.


Cold-Climate Regions

The frost-resistant design makes it suitable for temperate zones. In regions like Northern Europe or Canada, the system maintains pool temperatures at 25–28°C during spring and autumn, outperforming traditional systems by 20% in low-light conditions.


Eco-Conscious Projects

Align with green building certifications (e.g., LEED) by reducing carbon emissions. The RNE-VCA series is a cost-effective renewable energy solution for eco-friendly pool designs.


FAQ


Q1. How long does installation take?

Installation typically takes 4–8 hours for a standard residential system. The modular design allows for easy integration with existing filtration systems, and no specialized tools are required. Professional installation is recommended for complex setups.


Q2. Does it work on cloudy days?

Yes. The vacuum tubes efficiently capture diffused sunlight, maintaining 60–70% of peak efficiency on overcast days. Performance is optimized in direct sunlight but remains effective in low-light conditions.


Q3. How much maintenance is required?

Annual maintenance includes cleaning tubes, inspecting seals, and checking water flow. Replace gaskets every 5–7 years to ensure airtight seals. No routine chemical treatments are needed.


Q4. Can it be used with a pool cover?

Yes. A pool cover reduces heat loss by 50–70%, enhancing the system's efficiency. Combining the RNE-VCA series with a cover extends the heating season and minimizes energy consumption.


Q5. What certifications does it hold?

The RNE-VCA series meets CE certification standards for safety and performance. Custom models can be certified for SRCC OG-100 or NSF 50 upon request, ensuring compliance with regional regulations.
