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

1. Operating screen
2. Manometer
3. Pump speed adjust switches
4. Temperature difference circulation pump
5. Flow rate indicator

- Q:What is the ideal orientation for solar water heater panels?
- Generally, for solar water heater panels, the most suitable orientation is towards the south in the northern hemisphere and towards the north in the southern hemisphere. This positioning guarantees that the panels receive the highest amount of sunlight during the day, thus maximizing their efficiency and ability to absorb heat. By facing towards the equator, the panels can capture the sunlight most directly, leading to increased energy output and enhanced water heating capacity. Nevertheless, it is crucial to take into account local elements like shading, roof angle, and regional climate in order to determine the optimal orientation for solar water heater panels.
- Q:Can a solar water heater be used in areas with limited access to technological advancements?
- Yes, a solar water heater can be used in areas with limited access to technological advancements. Solar water heaters are relatively simple and low-tech devices that use the sun's energy to heat water. They are independent of electrical grids or complex infrastructure, making them suitable for areas with limited access to technology. Additionally, solar water heaters are often more affordable and sustainable alternatives to conventional water heating methods in such areas.
- Q:Can a solar water heater be used in areas prone to earthquakes?
- Yes, a solar water heater can be used in areas prone to earthquakes. However, it is essential to ensure that the installation is done properly to withstand seismic activities. Reinforcements, such as securing the system to the ground or building, can be implemented to minimize the risk of damage during an earthquake. Additionally, using flexible pipes and proper insulation can help prevent potential leaks or ruptures. Regular maintenance and inspections are crucial to identify any potential weaknesses and ensure the system's continued safe operation.
- Q:Are there any financial incentives for selling excess solar-heated water back to the grid?
- Yes, there are financial incentives available for selling excess solar-heated water back to the grid. Many countries and regions offer net metering programs, which allow homeowners or businesses with solar water heating systems to receive credits or payments for the excess energy they generate and feed back into the grid. Under net metering, the surplus energy is measured by a bi-directional meter, which tracks the amount of electricity generated and exported to the grid. These credits can then be used to offset future energy consumption or can be sold back to the utility company at a predetermined rate. Additionally, some governments provide feed-in tariffs (FITs) or feed-in premiums, which guarantee a fixed payment for each kilowatt-hour of solar energy generated and fed back to the grid. These financial incentives not only help to offset the initial investment in solar water heating systems but also encourage the adoption of renewable energy sources and support the overall sustainability goals. It is important to check with local utility companies, government agencies, or renewable energy associations for specific details and eligibility criteria regarding financial incentives for selling excess solar-heated water back to the grid.
- Q:Can a solar water heater be used in areas with high levels of dust or sandstorms?
- In areas with high levels of dust or sandstorms, a solar water heater remains usable. Nevertheless, to maintain its optimal performance, regular maintenance and cleaning may be necessary. Dust and sand particles have the potential to settle on the solar panels, thereby reducing their efficiency in capturing sunlight. Consequently, periodic cleaning of the panels becomes crucial to eliminate any accumulated debris. Furthermore, it is advisable to install filters or screens to prevent dust or sand particles from entering the water heating system. Consistent inspection and maintenance will guarantee the solar water heater's continued effective functioning in such environments.
- Q:Can a solar water heater be used in areas with limited access to sustainable energy policies?
- Yes, a solar water heater can be used in areas with limited access to sustainable energy policies. Solar water heaters rely on the sun's energy to heat water, making them a sustainable and renewable option regardless of the local energy policies. They can provide hot water without the need for electricity or traditional fuel sources, making them a viable solution for areas with limited access to sustainable energy resources.
- Q:Can a solar water heater be used in areas with limited maintenance resources?
- Yes, a solar water heater can be used in areas with limited maintenance resources. Solar water heaters are relatively simple and durable systems that require minimal maintenance. They usually consist of few moving parts and are designed to withstand various weather conditions. Regular inspections and occasional cleaning of the system's components are usually enough to keep it functioning efficiently. Additionally, the lack of reliance on electricity or fuel for operation makes solar water heaters a reliable and cost-effective option for areas with limited maintenance resources.
- Q:Can a solar water heater be used in a multi-story building?
- Absolutely! A solar water heater is perfectly suitable for a multi-story building. It can either be installed on the rooftop or in a designated area that receives plenty of sunlight. The setup typically includes solar panels, which capture the sunlight, a water storage tank, and a circulation pump. In a multi-story building, the solar panels can be connected to the water storage tank through pipes that run throughout the entire structure. With the help of the circulation pump, the heated water can be distributed to different floors and taps. By harnessing solar energy, a solar water heater can efficiently provide hot water for numerous units or apartments in a multi-story building, lessening the reliance on conventional heating methods and reducing energy expenses.
- Q:How does the efficiency of a solar water heater compare to a gas water heater?
- The efficiency of a solar water heater is generally higher than that of a gas water heater. Solar water heaters utilize sunlight to heat water, which is a renewable and abundant energy source. On the other hand, gas water heaters rely on burning natural gas or propane to heat water. Solar water heaters have lower operating costs, as they do not require fuel consumption, whereas gas water heaters can be expensive to run, especially if gas prices are high. In terms of environmental impact, solar water heaters are much more sustainable, as they do not produce greenhouse gas emissions during operation. However, the efficiency of a solar water heater can vary depending on factors such as location, climate, and system design, whereas gas water heaters tend to have a more consistent efficiency rating.
- Q:What is the warranty period for a solar water heater?
- The warranty period for a solar water heater typically ranges from 5 to 10 years, depending on the manufacturer and specific model.
