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 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 certifications or standards should a solar water heater meet?
- A solar water heater should meet certifications and standards such as the Solar Rating and Certification Corporation (SRCC) certification, which ensures the system's performance and efficiency. It should also meet industry standards like the International Organization for Standardization (ISO) standards for quality management and environmental management systems. Additionally, adherence to safety standards, such as UL 174 or CSA C22.2 No. 110, is crucial to ensure the heater meets electrical and safety requirements.
- Q:Can a solar water heater be used in areas with high levels of saltwater?
- Yes, a solar water heater can be used in areas with high levels of saltwater. However, special considerations need to be taken to prevent corrosion and damage to the system. Using materials that are resistant to corrosion, such as stainless steel or copper, and implementing appropriate maintenance and cleaning practices can help ensure the longevity and efficiency of the solar water heater in such areas.
- Q:Can a solar water heater be used to heat domestic hot water as well as space heating?
- Yes, a solar water heater can be used to heat both domestic hot water and space heating. There are two main types of solar water heaters that can be used for this purpose: active solar water heaters and passive solar water heaters. Active solar water heaters use pumps and controls to circulate water or heat transfer fluid through the system. These systems can be designed to not only heat the domestic hot water but also transfer the heated fluid to a heat exchanger or radiant flooring system for space heating. The heated fluid can then be used to warm the air in the space or provide radiant heat through the floors. Passive solar water heaters, on the other hand, rely on natural convection and gravity to circulate the water or heat transfer fluid. These systems are typically used for domestic hot water heating but can also be integrated with space heating systems. For example, a passive solar water heater can be connected to a radiant flooring system that allows the heated fluid to warm the floors and provide space heating. In both cases, the solar water heater can be a cost-effective and sustainable solution for providing both domestic hot water and space heating. By utilizing the sun's energy, these systems can significantly reduce the reliance on traditional heating methods, reducing energy bills and carbon footprints.
- Q:Why can not go on the solar water heater
- Two, the reasons for not Sheung Shui1 tap water or water pressure is too low2 pipeline interface off or damaged. Contact the maintenance department for repair or replacement3 valve failure, not open. Contact the maintenance department for repair or replacement4 vacuum tube damaged. Contact with maintenance department for replacement
- Q:What are the common safety precautions for installing a solar water heater?
- Some common safety precautions for installing a solar water heater include ensuring proper training and knowledge of installation procedures, wearing appropriate protective gear such as gloves and eye protection, following manufacturer's instructions and guidelines, securing the equipment properly to prevent accidents or falls, turning off power sources before starting the installation process, and obtaining necessary permits and inspections to ensure compliance with local building codes and safety regulations.
- 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 installed on an existing home?
- Certainly! It is indeed possible to install a solar water heater on a preexisting house. In fact, it is quite common to retrofit an existing home with a solar water heater as a means of reducing energy consumption and decreasing utility expenses. The installation procedure typically entails the placement of solar panels on the roof or in a sunny location on the property in order to harness the energy of the sun. These panels are then connected to either a storage tank or the home's current water heating system. While the practicality of installation may vary depending on factors such as available roof space, orientation, and local building regulations, professional installers possess the expertise to evaluate the suitability of a solar water heater for a preexisting home and offer tailor-made solutions.
- Q:How does a solar water heater perform during winter months?
- A solar water heater can still perform well during winter months, although its efficiency may be slightly reduced due to shorter daylight hours and less direct sunlight. However, with proper insulation and design, it can still generate enough heat to provide hot water. Additionally, some systems are equipped with backup heating elements to ensure a continuous supply of hot water during colder periods.
- Q:Can a solar water heater be integrated with an existing water heating system?
- Yes, a solar water heater can be integrated with an existing water heating system. In fact, many homeowners choose to install a solar water heater as a supplement to their existing system, rather than replacing it entirely. This allows them to take advantage of the energy efficiency and cost savings of solar power while still having the backup of their traditional water heating system. The integration process typically involves connecting the solar collector panels to the existing water storage tank or hot water distribution system. This can be done by either installing a separate tank for solar-heated water or by using a heat exchanger to transfer the solar heat to the existing tank. By integrating a solar water heater with an existing system, homeowners can enjoy the benefits of renewable energy without completely overhauling their current setup.
