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

 

Solar water heaters working station component:
1. Operating screen 
2. Manometer 
3. Pump speed adjust switches 
4. Temperature difference circulation pump 
5. Flow rate indicator 
6. Return circuit connector 
7. Safety valve

Q:Solar water heater is really easy to bad
Vacuum tube.Vacuum tube is the core component of solar water heater, but also the heart of the solar water heater. The performance of the vacuum tube is affected by the coating technology, such as cleaning, coating, vacuum pumping, sealing and so on. But some super low vacuum tube using the solar water heater has the following defects: low vacuum, only quality products 1/100 tube residual impurities and water vapor, a high temperatures encountered into gas, vacuum reduction; low vacuum film stability of two or three years, intimal layer aging, fall off, resulting in the thermal performance decays rapidly, unable to absorb enough heat
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:How to use solar water heater for temperature sag
If you don't need to use solar water heater for a long time, you can turn off the water supply valve first, then put the water in the solar water heater and pipe line, which can effectively avoid the freezing of the solar energy pipeline. If the winter is often the use of solar water heaters, the best night to stop the water, the solar water heater of the water remaining in the vent in the morning, if sunny, plus the amount of water, if cloudy, cold weather, do not add water, is also a good method to prevent pipe blockage or freeze freeze cracking.
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.
Q:Solar water heater in the end do not use electricity
Solar water heaters are in need of electricity, heating with solar energy in summer and heating in winter.
Q:The solar water heater without water becomes bad
There will be effect ~ solar vacuum tube air drying is not good, because the tube wall temperature can reach four hundred degrees, so the air drying vacuum tube will direct sun differential blasting, good vacuum tube as Linuo, will reduce the life, such as this can be used for twenty years, will result in changes in fruit and molecular film the structure of thermal effect due to air drying, reduce the duration of life.
Q:Two solar water heater is the connection method?
The electric auxiliary power vacuum tube solar water heater is very low, control is not good, can increase the volume of water heater a floor type chamber shape at the outlet of the solar water heater, when the temperature is low by manual electric auxiliary heating, heating power from the general 2.4/3.6/ 4.8KW.
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:How to defrost the solar water heater
Pipeline frozen treatment: winter, the pipeline is frozen is a very common thing, such as the discovery of the pipeline has been frozen but the pipeline has not yet cracked, the temperature can generally be automatically after the rebound. Can also be used to dry hair dryer blowing, or with a towel wrapped in the water pipe, and then slowly poured with warm water poured, can not be used to fire baking, tapping the pipe or boiling water with hot, so that the pipeline burst. Repeatedly freezing easily cracking pipes, so therefore need to strengthen the pipeline insulation measures.
Q:Villa solar water heater, villa solar water heater
Villa solar water heater from abroad, has been extended for decades in Europe and the United States, because of its price is 2-3 times of ordinary solar energy, so in the domestic promotion is relatively slow, and now the vast majority of domestic solar water heater is one of the non pressure, due to the non pressure solar water heater using little pressure, Sheung Shui easy to control problems, many problems such as unsightly appearance installation, villa type solar water heater has the advantages of high water pressure, no management, beautiful appearance and has gradually been favored by wealthy families.
