non pressure 500liter solar water heater

Overview

Designed for versatility and sustainability, our Non-Pressure Solar Water Heater offers a smart alternative to traditional water heating methods. Its open-circuit design ensures safe and effortless operation, making it accessible to users with minimal technical knowledge. The system excels in converting solar energy into hot water with minimal heat loss, backed by a modular architecture that allows scalability. Whether for small households or large institutions, this heater promotes energy independence and environmental stewardship without compromising convenience. Advanced safety features, including anti-scald valves and lightning protection, ensure user safety in diverse environments.

Features

1. Smart Temperature Display: Optional digital monitors show real-time water temperature and system status. Bluetooth-enabled models sync with mobile apps for remote monitoring.

2. Quick-Connect Tubes: Pre-insulated pipes with snap-lock fittings simplify installation and reduce thermal loss during water transfer.

3. Eco-Friendly Refrigerant: Uses non-toxic propylene glycol for frost protection in cold climates. The closed-loop antifreeze circuit operates independently of potable water.

4. Customizable Configurations: Mix-and-match components to tailor capacity and collector type (vacuum tube/flat plate). Add-on kits enable pool heating or space heating integration.

5. Anti-Freeze Design: Auto-drain function prevents tube damage in freezing conditions. Manual drain valves allow complete water evacuation within minutes.

6. Global Certifications: Complies with ISO 9806, CE, and Solar Keymark standards for quality assurance. RoHS-compliant materials ensure environmental safety.

Applications

· Educational Institutions: Supplies hot water for dormitories, cafeterias, and laboratories. Solar-heated water supports chemistry experiments and sanitation needs.

· Healthcare Facilities: Ensures sterile hot water for medical equipment and sanitation. Ideal for surgical instrument sterilization and patient bathing.

· Retail Chains: Supports car washes, laundromats, and restaurants seeking green certifications. Reduces utility costs while enhancing brand sustainability.

· Marine Platforms: Coastal or floating installations benefit from corrosion-resistant materials. Saltwater-proof models suit offshore oil rigs and yacht marinas.

· Government Projects: Eligible for renewable energy subsidies in over 30 countries. Widely adopted in public housing and municipal heating initiatives.

FAQ

1. How hot can the water get?

Average temperatures range from 50°C to 90°C, depending on sunlight availability and system size. Stagnation temperature can reach 200°C, necessitating heat dissipation features.

2. Is roof reinforcement needed?

The system weighs 150–400 kg when full; structural assessment is advised for weak rooftops. Lightweight aluminum frames are available for fragile roofs.

3. Can it be installed vertically?

Yes, vertical setups save space and are suitable for wall-mounted applications. East-west oriented vertical collectors maintain efficiency in limited spaces.

4. What payment terms are available?

We accept LC, T/T, and flexible OEM/ODM terms for bulk orders. Financing options include 12-month installment plans for qualifying buyers.

5. How to optimize winter performance?

Increase collector tilt angle by 10°–15° during winter. Insulate exposed pipes and use a darker tank color to enhance heat absorption.

The solar hot water heater adopts solar vacuum tube technology, the solar evacuated tubes absorber will collect heat from the sunlight and transfer into water inside the tubes. The tube water is heated to rise up and tank cold water sink down to creat a circulation, called thermosiphon effect. The water tank will be gradully full of hot water as the tubes keep collecting heat from the sunlight.  It is no need of electricity heating. It is only by solar thermal heating.
