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 is the number of 18 liters?
- The utility model relates to a solar water heater, which is a device for converting solar energy into heat energy, which is used for heating water from low temperature to high temperature, so as to meet the requirement of hot water use in people's life and production.
- Q:Solar water heater, winter can be used in rural cottage
- The solar water heater, in rural cottage in winter, generally the use of solar water heaters will be placed in rural areas on the roof, you can contact the sun very good light, suitable for people to use the temperature reached.
- Q:Solar water heater can produce a lot of hot water a day
- By sunlight, the photons hit the coating, solar energy into heat energy, water from the outside of the coating absorbs heat, the water temperature increases, the density decreases, the hot water to move up, and more than a significant drop in cold water. Hot water is always on the upper part of the tank. The temperature rise of the hot water in the solar water heater is not related to the outside temperature. When the opening of the kitchen or bath in any one of the taps, the water heater will rely on the natural fall out, the greater the gap, the higher the water pressure.
- Q:Why is the solar water heater not hot
- This requires the actual view to know, to find a good weather, it is estimated that the water in the solar water tank under normal circumstances should be hot, then go upstairs to the actual view, touch the vacuum tube
- Q:Solar water heater inside the sediment (stains) how to clean up
- A hand brush was a cleaner solar decentralization point on the line that wash brush is best to use the new cushion pad to protect the same tank
- Q:What about the cold water heater
- Solution: replace the mixing valve, re layout of pipeline!General solar outlet pipe and the water pipe is a root, such as encountered in the water and the water is a case of whether the valve failure caused!
- Q:Why is my solar water heater out of the hot water is very small
- The water heater is bad or due to the use of time is too long, did not do the timely cleaning work, resulting in the water inlet of the filter or internal clogging phenomenon, so that when the switch is too small.
- Q:What can replace the solar water heater
- Only the emperor of the winter crown 210 hot water machine can replace the current solar water heater or 3G central hot water unit!
- Q:What are the requirements of domestic solar water heater
- Shortcomings:1 large area on the floor of the installation of insulation;2 hot water pipeline for more than ten meters, each use to waste a lot of water;3 the need for a full day of sunshine in order to heat the water, when the weather is good can only ensure that there is hot water at night, during the day and at night there is little hot water available, can not guarantee the user 24 hours hot water supply, poor comfort;4 solar water heater lighting board must be installed on the roof, both large and heavy, but also affect the construction of the beautiful (the more obvious the more high-end residential areas), but also easy to damage the roof waterproof layer;5 photoelectric complementary, in fact, can not be properly implemented.6 now more than 99% of the market are very backward, non pressure type, commonly known as the water". The water, the water is only a water pipe, the use is very inconvenient, simply can not talk about comfort.
- Q:How to choose solar water heater?
- Should also pay attention to the vacuum pipe between the pipe spacing, the general two tube center distance is about 70mm.4 home solar water heater bracket design should be reasonable, should have enough strength and stiffness (added: there are corrosion resistance, do not use two years of support down) to ensure adequate bearing capacity. In some areas of daily wind, especially in coastal areas, in the purchase of domestic solar water heaters should also pay attention to the product in the design of wind resistance.5 currently on the market, a variety of reflector forms of household solar water heater is diverse, there are flat reflectors, reflective surface plate, embossed aluminum and so on, in the purchase should pay attention to the heat absorbing surface reflective plate design products can make full use of the vacuum tube, the vacuum tube to the maximum extent by light. (supplement: now most of them do not have a reflective board, and businesses to save costs, user products improve the wind resistance, not worth mentioning)
