Product Description:

Solar water heaters features
1. The upright tank can make the water temperature to a high level. It can hot the water instantly
2. The tank inside the building, the hot water loses less energy than the normal one 
3. The solar collector and the tank of solar water heater is separated, that makes the system combine with the building perfectly, which will reduce the sightseeing for the building and environment around 
4. Back up with electric heater so that in the day without sunshine hot water can also be used
5. Can be combined with gas or electric heater 
6. Max. Pressure: 12bar; Operating Pressure: 6 bar
7. It can be used for other function, such as warming

 

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 
8. Expansion vessel connector9. Return circuit connector 
10. Wall mounting 
11. Expansion vessel:8L

Q:How to identify the solar water heater is good or bad?
At present, the market has at least 30 solar water heater brands, with the exception of domestic famous enterprises like Beijing Tsinghua Sunshine solar water heater production, there are some fish in the assembly of products and small factory crudely made products.
Q:Solar water heater power consumption?
If the weather is good, do not need electricity, through the sun can make the water tank temperature rise.
Q:Solar water heater in and out of the water pipes are connected to the home with the above?
Solar water heater is the first to enter the cold water storage tank, and then through the heat collector to heat the water tank.
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)
Q:What is the heating principle of solar water heater?
What is the working principle of vacuum collector solar water heater?By manual or automatic water supply system for thermal insulation water tank, heat preservation water tank is communicated with the air through the exhaust port, the water outside the exhaust through the exhaust port, when the water is discharged through the exhaust port of the air pressure inside the tank inlet inward, always with the external balance, full of water through the water tank overflow signal off inlet valve. The solar vacuum tube, absorbing coating to absorb solar energy and water in the tube of the heat exchange tube inner wall selective tube, the water temperature rises, the density decreased, and the water in the water tank has the density difference of formation heat siphon head, the water in the water tank in automatic cycle pressure without the aid of it to realize the heating process.
Q:Open a solar water heater manufacturers need to have what conditions
If you and your friends and family partnership investment company limited, can choose ordinary, the minimum registered capital of 30 thousand yuan; if only you a person as a shareholder, then select a limited company, the minimum registered capital of 100 thousand yuan. Two, the company registered 1 steps: nuclear Name: to Industrial and Commercial Bureau to obtain an "enterprise (famous) name pre approved application form", fill in your company ready to take the name of the Internet by Industrial and Commercial Bureau (Industrial and Commercial Bureau intranet search) if available, if not the same, you can use this name, will issued an "enterprise (famous) name pre-approval notice". This step is 30 yuan fee.
Q:Why is the heating surface of the solar water heater tilted
Large inclination angle, large heating area, as well as the solar radiation angle.Solar water heater is the main source of heat.
Q:Two solar water heater is the connection method?
Because of the common solar water heater is the open water tank, when the water heater two side by side when pressure is the same, if you use the series, the first solar water heater into the hot water is water with tap water, but in second when there is no water pressure, so that the second sets of solar water heaters because there is no pressure to enter the water will be greatly reduced, in order to avoid this problem, suggest the use of parallel import of water, and the water outlet with a self suction booster pump to ensure the water pressure.
Q:Solar water heaters are still required to install the check valve accessories
Need to install to prevent hot water backflow.The hot water flow is mainly refers to the low pressure tap water (tap water pressure is insufficient to reach the roof) or tap water pressure is not stable and high and low, at this time, Sheung Shui solar water heater, the water heater on the roof, the natural water level drop, the water heater will flow to the water in the road, if there are many hot water heaters, not only not to cold water, the result will make the hot water flow, water reverse, hot water outflow phenomenon caused by the user in tap water downstairs. To solve the problem of hot water backflow, the installation of check valveIn the water control valve installed around.
Q:Solar water heaters have odor, for what reason, how to do?
In addition to stainless steel solar glass, a rubber ring or food grade, on the theory that solar energy will not cause odor, but it is easy to have a taste of the pipeline. Should be the pipeline problem. If the pipeline is a problem, it is recommended to clean up the pipeline
