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: What is the difference between active and passive solar water heaters?
- Active and passive solar water heaters are two different types of systems that harness solar energy to heat water. The main difference between them lies in how they circulate the water and transfer heat. Active solar water heaters utilize pumps or other mechanical devices to circulate water through the system. These systems typically consist of solar collectors, storage tanks, and controls. The solar collectors, usually mounted on the roof or a nearby area with ample sunlight exposure, absorb the sun's heat and transfer it to the water. The heated water is then pumped into a storage tank, where it can be used for various purposes. Active systems are more complex and require electricity to operate the pumps, but they tend to be more efficient and can provide a continuous supply of hot water. On the other hand, passive solar water heaters rely on natural convection and gravity to circulate water without the need for mechanical components. They usually consist of a solar collector and a storage tank, but without any pumps or controls. The solar collector absorbs heat from the sun, and as the water inside it heats up, it naturally rises into the storage tank due to the difference in density. As hot water is drawn from the tank, cold water is pulled down into the collector, creating a continuous flow. Passive systems are simpler and don't require electricity, but they may not be as efficient as active systems and may have limitations in terms of the amount of hot water they can provide. In summary, the main difference between active and passive solar water heaters is the method of water circulation and heat transfer. Active systems use pumps and controls to circulate water and offer higher efficiency, while passive systems rely on natural convection and gravity for circulation and are simpler but potentially less efficient. The choice between the two depends on factors such as budget, energy requirements, and available space.
- Q: Can a solar water heater be used in areas with limited access to nuclear power?
- Indeed, solar water heaters are a viable choice for regions hindered by limited nuclear power availability. By harnessing the power of the sun, these heaters efficiently warm water, negating the necessity for nuclear power or any external energy input. Their environmentally conscious and sustainable nature deems them fitting for usage in areas devoid of nuclear power accessibility. Furthermore, solar water heaters can be effortlessly incorporated into both residential and commercial structures, offering a dependable and economical substitute to conventional water heating techniques.
- Q: How does the orientation of a solar water heater impact its performance?
- The orientation of a solar water heater greatly affects its performance. Ideally, the heater should be facing south in the Northern Hemisphere and north in the Southern Hemisphere to maximize sun exposure throughout the day. Proper orientation ensures that the solar panels receive the most direct sunlight, increasing their efficiency and effectiveness in heating water.
- Q: How to correctly use solar water heater
- Using techniques of solar water heater:A, take a bath, if the water in the solar water heater has been exhausted, but people still do not wash clean, then can last a few minutes in cold water, use cold water sink, hot water floating principle, the vacuum tube in a hot water bath, can
- Q: Can a solar water heater be used in areas with high levels of water chlorination?
- Yes, a solar water heater can be used in areas with high levels of water chlorination. The chlorination process does not affect the functionality or efficiency of a solar water heater. However, it is important to regularly maintain and clean the system to prevent any potential buildup or corrosion due to the chlorinated water.
- Q: Can a solar water heater be used in areas with high pollution levels?
- Yes, a solar water heater can be used in areas with high pollution levels. The efficiency of a solar water heater may be slightly reduced due to the presence of pollutants in the air, but it can still effectively heat water using sunlight. Regular maintenance and cleaning may be required to ensure optimal performance in polluted areas.
- Q: How does the type of heat exchanger impact the performance of a solar water heater?
- The type of heat exchanger plays a crucial role in determining the performance of a solar water heater. Different heat exchanger designs can significantly affect the efficiency and effectiveness of heat transfer from the solar collectors to the water. Factors such as heat transfer rate, pressure drop, and resistance to scaling or corrosion can vary depending on the type of heat exchanger used. Choosing the appropriate design can optimize the heat transfer process, maximizing the overall performance and energy efficiency of the solar water heater.
- Q: Can a solar water heater be installed in a rented property?
- Yes, a solar water heater can be installed in a rented property with the permission and agreement of the property owner or landlord. It is important to discuss the installation and any potential modifications with the landlord to ensure compliance with rental agreements and to avoid any damage or liability issues.
- Q: The controller of the solar water heater does not show the power on screen
- . Vacuum tube type solar water heater is composed of a heat collecting pipe, a water storage tank and bracket and other related parts, converting solar energy into heat energy mainly rely on vacuum tube, vacuum tube using the principle of cold water sinking floating, the water circulation and desired hot water.
- Q: Can a solar water heater be used for both domestic hot water and space heating?
- Yes, a solar water heater can be used for both domestic hot water and space heating. Solar water heaters utilize the sun's energy to heat water, which can then be used for various purposes, including domestic hot water and space heating. This can be achieved through the use of a heat exchanger or a dual-purpose tank, where the heated water is transferred to the space heating system to provide warmth.
