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 can be installed with pressure pump, how to add, how much? Easy to use?
- Install pressure pump step:1, remove the intake pipe.2, the pressure on the end of the booster pump received water inlet pipe, one end of the water faucet
- Q:How solar water heater winter.
- First, if the winter is no longer using solar water heaters, solar energy can be used up or emptied of water, the pipe is empty, it will not freeze.
- Q:How long do you need to deal with solar water heater in summer?
- In this case, if the water tank is in a state of high temperature and high pressure, the sealing ring will soon be aging, and the material of the heat preservation material will also be aging and shrinking
- Q:How to correctly use solar water heater
- Using techniques of solar water heater:A, take a bath, if the water in the solar water heater has been exhausted, but people still do not wash clean, then can last a few minutes in cold water, use cold water sink, hot water floating principle, the vacuum tube in a hot water bath, can
- Q:What is the quality standard of solar water heater
- You can look at several aspects:1 vacuum tube, which is the core of solar energy, the vacuum tube is not good, the solar energy can not reach a certain temperature, the use of summer does not matter, but in winter there is no way to use.Some ultra low-cost solar water heater using the vacuum tube has the following defects: low vacuum, only high-quality products 1/100; a large number of impurities and residual water vapor pipe, 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:Solar water heater vacuum tube length?
- Solar energy is a clean and free energy, and now the technology of solar energy is very mature
- Q:Air energy water heater and solar water heater which is good
- Solar water heater as the name suggests is to rely on the sun, relying on technology to convert sunlight into heat energy, the water from low temperature holiday to high temperature, to meet people in the life of the water heater use. The solar water heater installation is reliable, low carbon environmental protection; solar energy processing technology, good heat transfer performance, hot water production, in line with the family for personal use; in the cold winter solar water heater with strong frost resistance in the summer a large area of the solar installation can also heat insulation layer effect on the floor.
- Q:Solar water heaters have an impact on people's health?
- Wuxi stainless steel market 2007-1-13 9:22:15 currently on the safety of the solar water heater water storage has not done testing, but considering the water heater material and pipe rust and other factors, as a precaution, it is best not to use it as drinking water.Solar water heater water is not replaced every day, may bring two pollution. Solar water heater belongs to metal, if not cleaned for a long time, may also produce pollution. It is recommended that people not to drink water in the solar water heater, drinking harmful to human health.
- 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:Water storage capacity of solar water heater
- There is a direct relationship between the cost of the solar water heater and solar collector area and volume of water tank insulation, close to the proportional relationship, considering the user long-term, comprehensive benefit, collector area appropriate larger solar options, to the benefit of users, because the initial investment point of solar hot water supply. After a few years, the operation cost more.
