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
Solar water heaters working station component:
1. Operating screen
2. Manometer
3. Pump speed adjust switches
4. Temperature difference circulation pump
5. Flow rate indicator
6. Return circuit connector
7. Safety valve

- Q: Can a solar water heater be used to heat a swimming pool?
- Yes, a solar water heater can be used to heat a swimming pool. Solar water heaters use the energy from the sun to heat water, which can then be circulated through the pool's filtration system to warm the pool. This is an environmentally friendly and cost-effective way to heat a swimming pool.
- Q: What is the difference between an active and passive solar water heater?
- An active solar water heater uses a pump or other mechanical device to circulate water or heat transfer fluid through the system, while a passive solar water heater relies on natural convection or gravity to move water through the system.
- Q: What are the components of a solar water heater system?
- The components of a solar water heater system typically include solar collectors, a storage tank, a heat transfer fluid, a circulation pump, and a control system.
- Q: Can a solar water heater be used in areas with saltwater or brackish water?
- A solar water heater is capable of functioning in regions with saltwater or brackish water. However, it is crucial to take specific measures and employ appropriate materials to guarantee the system's durability and effectiveness. Insufficient precautions may result in the corrosion and harm of the solar water heater's components due to saltwater or brackish water. One prevalent technique to safeguard the system is by utilizing corrosion-resistant materials such as stainless steel or plastic for the pipes and storage tanks. These materials are less prone to the corrosive impact of saltwater. Furthermore, regular maintenance and cleaning of the system can prevent the accumulation of salt deposits and ensure optimal performance. In areas with a high salt content in the water, it is also advisable to install a water softener or desalination system. These systems aid in eliminating or reducing the salt content, thereby minimizing potential harm to the solar water heater. In summary, by employing appropriate precautions and conducting regular maintenance, a solar water heater can be effectively utilized in regions with saltwater or brackish water. This provides an environmentally friendly and cost-effective solution for hot water requirements.
- Q: Are there any disadvantages to using a solar water heater?
- Yes, there are a few disadvantages to using a solar water heater. Firstly, the initial installation cost can be high, which may deter some individuals from opting for this system. Additionally, the efficiency of solar water heaters can vary depending on weather conditions and location, meaning they may not be as effective in areas with limited sunlight. Lastly, solar water heaters require regular maintenance and occasional repairs, which can add to the overall cost and inconvenience.
- Q: How long does it take to install a solar water heater?
- The installation of a solar water heater typically takes around 1-2 days, depending on the complexity of the system and the experience of the installation team.
- Q: What is the impact of water flow rate on the performance of a solar water heater?
- The impact of water flow rate on the performance of a solar water heater is significant. A higher flow rate can effectively transfer more heat from the solar collectors to the water, resulting in faster heating and higher overall efficiency. However, excessively high flow rates can lead to reduced heat transfer efficiency and potential system malfunction. Conversely, lower flow rates may increase heat transfer efficiency but at the cost of slower heating and reduced overall performance. Therefore, finding the optimal water flow rate is crucial for maximizing the performance of a solar water heater.
- Q: What is the expected maintenance schedule for a solar water heater?
- The expected maintenance schedule for a solar water heater typically includes an annual inspection and cleaning of the solar panels, checking for any leaks or damage, and ensuring proper functioning of the system's components. Additionally, it is recommended to flush the system every 3-5 years to remove any sediment or mineral buildup. Regular monitoring of the system's performance and promptly addressing any issues is also important to ensure optimal efficiency and longevity.
- Q: Can a solar water heater be used in areas with high levels of snow accumulation?
- Yes, a solar water heater can still be used in areas with high levels of snow accumulation. However, there are a few considerations to keep in mind. Firstly, the snow accumulation on the solar panels can reduce their efficiency in capturing sunlight. Snow-covered panels will not be able to generate as much heat as clean panels. Regular maintenance and cleaning of the panels will be necessary to ensure optimal performance. Secondly, it is important to design the system in a way that allows for snow melt and drainage. The angle and orientation of the panels can be adjusted to maximize snow shedding, and the installation should include a slope to ensure that the melted snow can drain off the panels. Thirdly, insulating the pipes and storage tank can help prevent freezing and heat loss in extreme cold temperatures. This will ensure that the system continues to function efficiently and provide hot water even during snowy conditions. Lastly, it is worth noting that solar water heaters work through the absorption of sunlight, not necessarily heat. Therefore, even in areas with high levels of snow accumulation, as long as there is sufficient sunlight available, the solar water heater can still be effective. Additionally, using a backup heating system, such as an electric or gas heater, can provide hot water during extended periods of snow cover or low sunlight. Overall, while snow accumulation can pose some challenges, with proper design, maintenance, and insulation, a solar water heater can still be used effectively in areas with high levels of snow accumulation.
- Q: How much water can a solar water heater heat in a day?
- The amount of water that a solar water heater can heat in a day depends on various factors such as the size and efficiency of the system, the weather conditions, and the water demand. On average, a typical solar water heater can heat around 40-80 gallons (150-300 liters) of water per day. However, this can vary significantly and it's important to consider the specific specifications of the solar water heater being used.
