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: How does the efficiency of a solar water heater change with different water temperatures?
- The efficiency of a solar water heater typically increases as the water temperature decreases. This is because solar water heaters rely on heat transfer from the sun to warm the water, and the temperature difference between the water and the surroundings affects the rate of heat transfer. So, when the water temperature is lower, there is a greater temperature difference, leading to more efficient heat transfer and thus higher efficiency in heating the water.
- Q: What is the average installation cost for a solar water heater in different regions?
- The average installation cost for a solar water heater can vary depending on the region and various factors such as the size of the system, complexity of installation, and local market conditions. It is recommended to obtain specific quotes from local installers or consult regional solar energy associations for accurate and up-to-date information on installation costs in different regions.
- Q: How does the type of insulation used in a solar water heater impact its performance?
- The type of insulation used in a solar water heater directly impacts its performance by reducing heat loss and optimizing heat retention within the system. Insulation helps to keep the water in the solar collector hot for longer periods, ensuring efficient heat transfer to the water storage tank. The better the insulation, the less heat is lost to the surrounding environment, resulting in higher overall efficiency and improved performance of the solar water heater.
- Q: How does the efficiency of a solar water heater compare to a traditional water heating system?
- The efficiency of a solar water heater is generally higher than that of a traditional water heating system. Solar water heaters use sunlight to heat the water, which is a renewable and free energy source. On the other hand, traditional water heaters typically rely on fossil fuels or electricity, which can be costly and have a negative impact on the environment. Additionally, solar water heaters have advanced technologies and insulation that help retain heat, thus reducing energy consumption and operating costs. Overall, solar water heaters are a more efficient and sustainable option for heating water compared to traditional systems.
- Q: How to do solar water heater frozen
- 4, the flow of water is not easy to freeze, this principle can be used to prevent the freezing of solar pipe. Low temperature sunny day, the water heater is filled with water, several times a day, let the water heater in the warm water cooling water pipe to prevent freezing cold weather; not heated, open the tap, adjust the water flow velocity, the formation of water droplets, so as to prevent the freezing pipes. It should be noted that the method of freezing water is limited, when the temperature is below 5 degrees below zero, this method is basically useless.5, the most effective method is to install the pipeline antifreeze with tropical, usually pay attention to weather forecasts, or a thermometer at home, when the temperature is below zero, turn on the tropical power supply to the pipe insulation to prevent freezing
- Q: The house is ready to install a solar water heater, but do not know what kind of good do not know how to distinguish between bad? Here's a home called "God" brand, do not know how this brand? Want to know friends with us!! thank you!.....
- At present, the domestic solar water heater market sales of a wide range of solar collector, in accordance with the type to distinguish, can be divided into the vacuum tube and the plate; in accordance with the structure of distinction can be divided into integral and split; in accordance with the production process division, can be divided into pressure and non pressure. At present, most of the domestic solar water heaters sold in the market are mostly non pressure vacuum tube type solar water heater. When we buy domestic solar water heater, we should pay attention to the following points:
- Q: Can a solar water heater be used in areas with high levels of air pollution from traffic?
- Yes, a solar water heater can still be used in areas with high levels of air pollution from traffic. The performance of the solar water heater may be slightly affected due to reduced sunlight exposure, but it can still effectively heat water using solar energy. Regular maintenance and cleaning of the solar panels may be required to ensure optimal performance in such areas.
- Q: What are the components of a solar water heater?
- The components of a solar water heater typically include a solar collector, a storage tank, a heat exchanger, a pump or circulation system, and controls. The solar collector absorbs sunlight and converts it into heat energy, which is transferred to the water in the storage tank through a heat exchanger. The circulation system or pump ensures the movement of water between the collector and storage tank, while the controls regulate the temperature and ensure efficient operation of the system.
- Q: Does a solar water heater require a backup system?
- Indeed, a backup system is typically necessary for a solar water heater. Despite their high efficiency in converting sunlight into heat energy, solar water heaters may not be able to consistently supply hot water throughout the year, particularly during periods of limited sunlight or dense cloud coverage. Therefore, it is crucial to have a backup system in place to guarantee a continuous flow of hot water. Backup systems can differ, but often involve an electric or gas-powered heating element that can be activated when solar energy is inadequate. This backup system comes into operation to heat the water when solar energy is unavailable, thus ensuring a steady provision of hot water.
- Q: What is the impact of nearby trees or vegetation on the performance of a solar water heater?
- The presence of nearby trees or vegetation can have a significant impact on the performance of a solar water heater. Trees or tall vegetation can cast shadows on the solar collectors, reducing their exposure to sunlight and lowering the efficiency of the system. This can result in decreased heating capacity and slower water heating times. Additionally, fallen leaves or debris from nearby trees can accumulate on the collectors, obstructing their surface and further reducing their efficiency. Therefore, it is important to ensure that the solar water heater is installed in a location that is free from obstructions caused by trees or vegetation for optimal performance.
