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:Solar water heater inside the scale how to clean it?
1, water temperature for a long time to maintain above 70 degrees;2, the water is relatively static state.The composition or composition of the scale is complex, usually not a single compound, but a chemical composition, and contains other chemical components. According to the chemical composition of the scale, generally can be divided into several kinds of carbonate, silicate sulfate scale scale, scale, scale, scale, mixed oil and iron oxide scale and dirt etc..The scale is a poor thermal conductivity material, will hinder the transfer of heat, the water heater is not uniformly heated, causing local overheating, or partial pressure, eventually damage the water heater, even in danger.
Q:The solar water heater how to remove rust
2, add some clean water, then rinse rinse a drained, so repeated several times, thoroughly rinsed after removing a clean, all after cleaning, into the water tank, water tank, water wash sundries;
Q:Solar water heater tube or tube good
To see the water capacity of the vacuum tube collector efficiency and the water tank is reasonable, in addition to concern whether the water temperature is high, should pay more attention to water capacity, some deliberately tank barrels do small, leading to the high temperature, low water unreasonable phenomenon
Q:Solar water heater can be used in winter
And this is a concern for many people, if not the use of solar energy in winter that means the utilization rate of solar energy is only half, this will greatly increase the cost of installation of solar water heaters, forcing consumers to choose other water heater system. In fact, the solar water heater technology now, the use of solar energy in winter is not a problem, as long as the snowstorm raging will not stop working, solar energy, free life hot water for our time.
Q:Solar water heater in winter should pay attention to what?
3, pipeline antifreeze and insulation is the keyPipe antifreeze solar water heater needs extra attention, especially the water tank and the water pipe junction, this time the local wind and water easy to shake, if the connection is not good water easily exposed, cold to freezing, causing cold water to hot water down phenomenon, so thermal insulation hose must to do a good job, a general insulation pipe length is two meters, each heat pipe connection to tape fastened to prevent disconnection when the wind or water.
Q:Who invented the solar water heater
Archimedes stood up and shouted, "the sun is reflected in the sails of the mirror!" He raised the mirror, a light reflection to the side of the central sail, reflected a weak spot. A woman who understood him, hurriedly raised the hands of the mirror, the light is reflected to the sails, some light and small spot.
Q:Buy solar water heater from which aspects of good or bad
Buy solar water heater, the four attention"First, the three components is the key to buy solar water heaters, analysis of production strength is very important. The strength of the enterprise is reflected in many places, and the key components are the most important. Three components include: vacuum tube, insulation layer and liner. The vacuum tube and the insulation layer determine the temperature rise and thermal insulation of the water heater, and the inner liner determines the life of the water heater, so these three parts are the core of the solar water heater.
Q:Why does the solar water heater not hot water?
Five reasons: if the installation of a fully automatic auxiliary tank, may be in the auxiliary tank of the ball valve closed lax or ineffective, resulting in cold water to continue to supplement the water temperature.Solution: replace the auxiliary water tank float valve and related components.
Q:Why is the heating surface of the solar water heater tilted
Because the sun in the earth sphere, you get the sun illumination area is not the same, that is to say the incident sunlight angle is different. Through scientific test, the solar water heater heating surface inclination and the local latitude of box in order to get the most light, if want to consider winter. In the local latitude plus 10 degrees. So, in fact, (*^__^*) O (a _ U) o
Q:Solar water heater is not how is it going?
The vacuum tube:There are a lot of families to install a vacuum tube solar water heater, vacuum tube is an important component of the absorption of solar heat source. Vacuum tube does not clean up for a long time will affect the ability to absorb heat, there will be only out of cold water hot water phenomenon. Vacuum tube solar water heater in sunny weather in summer, heat absorption fast, if no one at home for a long time without water, so that the water tank for a long time in a state of high temperature, high pressure, the problem will not be able to water tank aging. In addition, vacuum tube damage caused by insufficient heat, solar water heaters will cause no hot water. To clean up the vacuum tube in a timely manner, if there is damage to be replaced in a long time, no one at home should be placed in the vacuum tube to block the sun blocking.
