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?
- In addition, in the course of use, should be added to the tank with water, as far as possible so that the water temperature in the tank drops, it is best not to exceed 75 degrees, so that can reduce the scale of production.The formation of scale is a complex physical and chemical process, which has two aspects: internal and external factors. There is a water calcium and magnesium ions and heavy metal ions, is the root cause of scale formation is also called internal; two is a solid substance from the supersaturated water precipitation and adhere to the metal surfaces, is the external cause of the scale. When the water containing calcium, magnesium and other salts impurities into the heating body, the heat absorbed by the heat transfer to the high temperature, calcium, magnesium salts impurities will produce a chemical reaction, the formation of insoluble substances precipitation. When the concentration reaches a certain concentration, the precipitate will become a solid precipitate, the surface of the heated surface, forming a layer of "film", blocking heat transfer, this layer of "film" is called scale. Scale formation needs to achieve two basic conditions:
- 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:Solar water heater water pipe with plastic tube or PPR tube good
- Aluminum plastic pipe is a kind of middle longitudinal welded aluminum pipe, the inner and outer layer of polyethylene plastic and between layers of hot melt adhesiveA new type of composite pipe. Polyethylene is a non-toxic, odorless plastic, with good impact resistance, corrosion resistance, weather resistance. The compressive strength of the middle layer longitudinal welding Aluminum Alloy tube with metal, the impact resistance of the pipe is easy to bend rebound, aluminum-plastic composite pipe with metal pipe and plastic pipe two strong pressure characteristics of anti acid corrosion resistance, is a model of a new generation of pipe. Plastic pipe (plastic composite pipe) is a kind of pipe is more popular on the market, the current market there are relatively well-known HSBC, Kim and Meifeng, due to its lightweight, durable and convenient for construction, and the aluminum pipe (plastic composite pipe) can bend more suitable for use in the home.
- Q:Solar water heater can not put hot water
- 3 water, water to the block (removable nozzle. Discharge scale can be put for a while.)4 if the automatic Sheung shui.
- Q:How long do you need to deal with solar water heater in summer?
- Method: if in the high temperature of summer once going on a business trip or a long time not at home, you should arrange for someone else often put hot water on the cold water, if you don't get help, can also be tube collector placed above the cover from the sun in a vacuum, wait until later to remove obstructions will go home.Method two: if you remove the solar vacuum tube, you can also remove the vacuum tube in the home after the preservation, and then back to the solar vacuum tube. The day before yesterday is that you must be very aware of the demolition process, if necessary, please master the professional demolition.
- Q:Solar water heaters are still required to install the check valve accessories
- Need, the solenoid valve automatically control itself has the function of manual water valve was the installation of the installation, but now a lot of pressure to see you still go not installed, they save cost, but will give users the trouble
- Q:Solar water heater in the end do not use electricity
- Auxiliary heating solar water heater.I do not know how to calculate the above users: solar water heaters, power consumption and the cost of the machine - electric water heater --10 years?!It's not so bad, is it? Low solar energy utilization is a reality. However, when the solar energy is good, there is no running; and the electric water heater as long as the heating power consumption, it can be no matter your cloudy sunny day!Moreover, the same capacity as the solar water heater but the number of solar energy, you may not pay attention to it?I don't like solar energy, but I think you say that there is a loss of authenticity and fairness.
- Q:Why is my solar water heater out of the hot water is very small
- Please check whether the water heater is in good condition, in the use of the process to do a good job of cleaning, cleaning up the blockage, to ensure that the water in the transmission process to maintain a smooth state.The size of the water pipe can be changed, so the utility model can effectively improve the amount of water in the conveying process, and can also avoid the obstruction of the small blockage, resulting in a small amount of water.
- Q:The problem of insufficient water pressure of solar water heater
- 1 you are not installed on the top of the solar energy, that is, if you live in the top floor, if so, then you need a booster pump2 if you do not live on the top floor, live in other floors, may be blocked pipe joints, you need to find
- Q:Solar water heater can not adjust warm water
- The reason is hot and cold water pressure is too large, if you tap water in the three layer is the hot water pressure is too small, if it is a simple cold water tank should be hot and cold water level varies a lot, to recommend appropriate adjustment, the best installation of thermostatic valve.
