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 to maintain it?
2, solar water heater in the use of the process should pay attention to what problems? Pay attention to water time. According to the weather conditions, determine the amount of water, to ensure that the appropriate bath temperature. Regularly check the water heater pipe, vent and other components are working properly. The air conditioning is serious or the sand is big, and the dry area is periodically flushed the vacuum tube.
Q:Solar water heater can be used in winter
Solar energy technology has been developed in China for more than 20 years, the technological breakthrough is changing rapidly, from our solar water heater users can see how big the market for solar energy. Now in addition to the traditional vacuum tube solar water heater, but also the emergence of a flat plate solar energy is more stable, the solar energy even when it rains can provide hot water, but the flat type solar water heater in our country use rate is not very extensive, so we have to vacuum tube solar water heater as an example, see the solar water heater technology to PK climate environment.Answer: solar water heater can be used in winter, my home is mainly installed in order to facilitate winter, water temperature and summer is not too bad.
Q:Three homes to install solar water heaters, how many roots, the length of the vacuum tube appropriate?
3 control instrument. These two sensors are most likely to be bad. (special attention must be given to lightning protection) general warranty is one year. What you say will give you an extension. Merchants can do the longest three years (this is a separate policy to manufacturers). General businesses do not want to look for trouble, only to the user that a year to see your eloquence
Q:How to choose solar water heater?
How to choose domestic solar water heaterAt present, the domestic solar water heater market sales of a wide range of solar collector, in accordance with the type to distinguish, can be divided into the vacuum tube and the plate; in accordance with the structure of distinction can be divided into integral and split; in accordance with the production process division, can be divided into pressure and non pressure. At present, most of the domestic solar water heaters sold in the market are mostly non pressure vacuum tube type solar water heater. When we buy domestic solar water heater, we should pay attention to the following points:
Q:Solar water heater does not add water, the sun will not be bad in summer
Vacuum tube solar water heater with high efficiency in the summer, sunny weather conditions, less than two days water temperature can reach the boiling point, if a long time without water, such as travel, tourism, to make the water a long time at high temperature and high pressure conditions, will accelerate the aging of the sealing ring, accelerated aging, polyurethane shrink, sometimes not exhaust smooth, too much pressure will make the tank expansion bad, will shorten the life of furring, water tank. Therefore, if you are no longer at home, others often should arrange hot water or cold water in the vacuum tube collector is placed on the cover from the sun, stay home, and then removed. If the winter is not a long time. You need to cancel the electric heating setting, to avoid wasting electricity.
Q:Who invented the solar water heater
Then there's a mirror and two mirrors...... All the way to the sail. After a while the sails were on fire and the enemy was scared to death. Many of the ships in Rome were burned, but the Romans could not find the cause of the fire. After more than 900 years, scientists have introduced the method according to the history of Archimedes created a concave mirror, the successful location of the mirror 45 meters away from the wood, and burnt the distance of 42 meters from the aluminum mirror. Therefore, many historians of science and technology have always regarded Archimedes as the ancestor of solar energy.
Q:What is the role of the solar water heater's reflector
The sun light in order to better use of resources, using the reflection plate will be missing from the two middle tube reflect sunlight to heat the nightside, improve the heat absorption tube.
Q:Solar water heater vacuum tube length?
Now most of the use of 1 m length of 8. Solar energy is used to heat water by using the heat of ultraviolet rays
Q:Air energy water heater and solar water heater which is good
The air relative to the solar water heater, the biggest advantage is to make up for the solar water heater can not produce efficiency all day long shortcomings, one night can only rely on the solar water heater water tank insulation effect to the temperature of the hot water has been saved to the night. After all, most people work during the day and go to bed at night.
Q:How can solar water heaters have electricity?
There is a feeling of electricity, what is your home electrical appliances or wires have been leakage. Your home is now the water pipe, the pipe has been connected to your home ground, so it will not kill, just let people numb.
