Introduction of Non-Pressure Solar Water Heater:
Non-pressure Solar Heater is one of the most economical solar water heating device with pretty high efficiency at the same time. It consists of hot water storage tank, solar vacuum tubes with mouth plug in storage tank, and bracket supporting tank and tubes.When cold water in evacuated tubes is heated with solar irradiation, as the specific gravities of hot water and cold water are different, hotter water goes upward to storage tank and colder water goes downward to glass tubes. through this continuous circulation, the cold water in storage tank will be gradually heated till sunset.
Solar water heaters working principle
1. The solar collector absorbs solar energy and transmits it to the solar water heater tank through circulation
2. When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically
3. The circulation pump makes heat-conducting liquid circulate automatically
4. The heat-conducting liquid transfers heat to water by lower heat exchanger in the water tank.
5. When the temperature difference between solar collector and heat pipe solar water heaters tank doesn't reach the set value, the circulation pump will be shut automatically
6. In case the temperature of the water tank does not reach Tmax, Electric Heating Element will start to work automatically

- Q: Can a solar water heater be used in swimming pools?
- Yes, a solar water heater can be used in swimming pools. Solar water heaters are designed to heat water using energy from the sun, and this can be effectively utilized to warm the water in a swimming pool. By connecting the solar water heater system to the pool's circulation system, the water can be heated naturally, reducing the need for traditional energy sources and saving on heating costs.
- Q: Can a solar water heater be used in areas with strict fire safety regulations?
- Yes, a solar water heater can be used in areas with strict fire safety regulations. Solar water heaters are generally considered safe as they don't rely on combustion or open flames for operation. They use solar energy to heat water, making them an environmentally friendly and fire-safe option for water heating.
- Q: How does the orientation of the solar panels affect the efficiency of a solar water heater?
- The orientation of the solar panels greatly impacts the efficiency of a solar water heater. For optimal performance, the panels should be positioned to receive maximum sunlight exposure throughout the day. Ideally, they should be facing south or north, depending on the hemisphere, and tilted at an angle equal to the latitude. This alignment ensures that the panels capture the most sunlight, thus maximizing their energy generation and ultimately improving the efficiency of the solar water heater.
- Q: Can a solar water heater be used in areas with limited access to sunlight for an extended period?
- No, a solar water heater cannot be effectively used in areas with limited access to sunlight for an extended period. The efficiency and performance of solar water heaters heavily depend on the availability of sunlight. In areas with limited sunlight, the system may not be able to generate enough heat to meet the desired water temperature and may not function optimally.
- Q: What are the types of solar water heaters? What advantage
- From the heat collecting partGlass vacuum heat collecting heat efficiency: is the highest part, the advantages of the heat collecting part does not need to increase in the thermal insulation layer, the vacuum glass tube now in high temperature, anti crack and thermal insulation performance, are the best, most manufacturers are using. The disadvantages of large volume, easy to scale pipe scale. Metal plate: excellent heat transfer performance of the metal sheet, covered with heat absorbing coating, the use of metal heat transfer, the heat absorbed in the tank. The utility model has the advantages of beautiful appearance and convenient installation, can be made into a flat plate, and is not easy to be damaged. Disadvantages: insulation to spend a high price, high cost, indirect is to increase the burden on consumers;
- Q: How much energy can a solar water heater save compared to traditional water heating methods?
- A solar water heater can save a significant amount of energy compared to traditional water heating methods, as it utilizes the sun's energy to heat water directly, reducing reliance on fossil fuels or electricity. On average, it can save up to 50-80% of energy consumption, leading to substantial cost savings and a reduction in carbon emissions.
- Q: What maintenance is required for a solar water heater?
- Regular maintenance is necessary to ensure the optimal performance and longevity of a solar water heater. Here are some key maintenance tasks that should be performed: 1. Inspecting and cleaning the solar collectors: The solar collectors, which absorb sunlight to heat the water, should be inspected regularly for any dirt, dust, or debris that might hinder their functionality. Cleaning them with water and a soft brush can help maintain their efficiency. 2. Checking the fluid level and quality: Solar water heaters use a heat transfer fluid to carry the collected heat to the water storage tank. This fluid should be checked regularly to ensure it is at the proper level and remains clean and free from contaminants. 3. Assessing the plumbing connections: Regularly inspect the plumbing connections, pipes, and valves for any leaks or damages. Addressing any issues promptly can prevent water and energy wastage. 4. Monitoring the temperature and pressure relief valve: The temperature and pressure relief valve play a crucial role in ensuring safety by releasing excess pressure or temperature buildup. Regularly checking and testing this valve is essential to avoid any potential hazards. 5. Verifying the performance of the pump: Solar water heaters often have a pump to circulate the heat transfer fluid. Checking the pump's performance, ensuring it is functioning properly, and inspecting the electrical connections are important maintenance tasks. 6. Maintaining the water storage tank: The water storage tank should be inspected periodically for any corrosion or sediment buildup. Flushing the tank to remove any accumulated sediment can help maintain its efficiency and prolong its lifespan. 7. Monitoring system performance: Keep an eye on the solar water heater's performance by regularly checking the temperature of the water and comparing it to the system's specifications. Any significant deviations may indicate a problem that needs attention. It is important to follow the manufacturer's recommendations for maintenance and consult a professional if any issues arise. Regular maintenance not only ensures optimal performance but also helps to extend the lifespan of the solar water heater and maximize energy savings.
- Q: Can a solar water heater be used for heating swimming pools?
- Yes, a solar water heater can be used for heating swimming pools. Solar water heaters utilize the energy from the sun to heat water, which can then be circulated through the pool to raise its temperature. This eco-friendly and cost-effective method is commonly employed for pool heating purposes.
- Q: What is the role of a solar controller in a solar water heater system?
- The role of a solar controller in a solar water heater system is to regulate and control the flow of heat transfer fluid between the solar collectors and the storage tank. It monitors the temperature of the fluid, ensuring that the collectors are operating efficiently and not overheating. The controller also manages the circulation pump, activating it when the temperature difference between the collectors and storage tank is sufficient for heat transfer. Additionally, it may have features like freeze protection and temperature display to provide additional functionality and user convenience.
- Q: What are the common safety precautions for installing a solar water heater?
- Some common safety precautions for installing a solar water heater include wearing protective gear such as gloves, goggles, and a mask, ensuring proper electrical grounding and wiring, following manufacturer's instructions and guidelines, turning off power supply before installation, avoiding working in adverse weather conditions, and seeking professional assistance if unsure about any aspect of the installation process.
