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 much does it cost to replace the solar panels in a solar water heater?
The cost to replace solar panels in a solar water heater can vary depending on several factors such as the size and type of the panels, the brand, and any additional installation or labor costs. On average, the cost of replacing solar panels in a solar water heater can range from a few hundred to a few thousand dollars. It is recommended to consult with a solar panel installer or a professional to get an accurate estimate based on your specific requirements.
Q:How does the cost of a solar water heater compare to other water heating options?
The cost of a solar water heater can vary depending on factors such as size, quality, and installation requirements. Generally, the upfront cost of a solar water heater may be higher compared to traditional water heating options like gas or electric heaters. However, solar water heaters have lower operating costs as they harness energy from the sun, resulting in significant savings on monthly electricity or gas bills. Over the long term, the cost of a solar water heater can be more economical due to reduced energy consumption and potential government incentives or tax credits available for renewable energy systems.
Q:How does a solar water heater affect water heater noise levels?
A solar water heater can significantly reduce water heater noise levels compared to traditional water heaters. This is because solar water heaters do not rely on a constantly running burner or heating element to heat the water. Instead, they utilize the sun's energy to heat the water, which eliminates the need for mechanical parts that create noise. Traditional water heaters typically generate noise from the combustion process, with the burner igniting and heating the water. This combustion process can produce a constant humming or rumbling sound, especially when the water heater is actively heating water. Additionally, the heating element in electric water heaters can also create a buzzing or humming noise. On the other hand, solar water heaters do not have a combustion process or heating element that generates noise. Instead, they use solar panels or collectors to absorb the sun's energy and transfer it to the water through a heat exchanger. As a result, solar water heaters operate silently and do not contribute to the overall noise levels in a household. Therefore, if noise reduction is a concern, opting for a solar water heater can be an excellent solution. Not only does it provide a more eco-friendly and cost-effective way to heat water, but it also eliminates the noise associated with traditional water heaters, promoting a quieter and more peaceful environment.
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 free energy from the sun, converting it into heat, while gas water heaters rely on burning fuel to produce heat. This means that solar water heaters can provide hot water at a lower cost and have a smaller environmental impact compared to gas water heaters. However, the efficiency of a solar water heater can vary depending on factors such as location, weather conditions, and the quality of the system installed.
Q:When solar water heater comes into China
All glass tubes in the beginning of a foreign application, there are U tube. Direct water, not accepted, is still not accepted until now, because the glass absorbs easily.
Q:Do solar water heaters need electricity?
Photo thermo electric conversion. Heat generation by solar radiation. The utility model is characterized in that the heat energy absorbed by the solar collector is converted into the working substance steam, and then the steam driven turbine drives the generator to generate electricity. The first process is the conversion of light and heat, and the latter is the conversion of heat and electricity.Optical electrical conversion. Its basic principle is to use the photovoltaic effect to convert solar radiation directly into electrical energy.
Q:What are the maintenance requirements for a solar water heater?
The maintenance requirements for a solar water heater typically involve checking and cleaning the solar collectors, ensuring proper fluid levels and pressure, inspecting and cleaning the storage tank, and monitoring the system for any leaks or malfunctions. Additionally, it is important to regularly inspect and clean the heat exchanger, replace any faulty parts or components, and perform an annual check-up to ensure the system is functioning optimally.
Q:Can a solar water heater be used in combination with a water softener?
Yes, a solar water heater can be used in combination with a water softener. The water softener helps to remove minerals and impurities from the water, which can prevent scale buildup and improve the efficiency of the solar water heater.
Q:When is the best solar water
The best time for solar water supply, before the sun comes out in the morning in the summer, the sun fell in the evening after the vacuum tube cooling water is best; winter morning after the best temperature rise water. Summer solar water heater water not too late (after 9 a.m.), vacuum tube dry burning is very easy to aging, after a day of sun exposure, the temperature is very high, to the solar water heater vacuum tube cooling down to water, or endure the stimulation sometimes hot and sometimes cold especially the vacuum aging. The tube is very easy to burst pipes. Winter should be careful not to water at night, should try to raise the temperature in the morning or at noon when the temperature is high water, so you can avoid the temperature is too low icing solar energy up bad. Don't use solar water heater at noon when the sun is hot. The correct use of solar water heaters, solar water heaters to grasp the best time to ensure the normal operation of solar water heaters, thereby extending the life of solar energy.
Q:What is the average installation time for a solar water heater?
The average installation time for a solar water heater typically ranges from one to three days, depending on factors such as the complexity of the system, the size of the property, and any existing plumbing or electrical work required.
