45 way to extend the life of solar water heaters

In order to extend the service life of solar water heaters, the user during use should note the following points:

1, night in a timely manner after the family bath feed cold water.

2, vacuum dry prolonged sun exposure over 15 minutes, the absolute prohibition immediately feed cold water, in order to avoid a vacuum dry temperature (up to 80c) injected into the cold water suddenly broken. feed cold water should be in the evening or in the morning before sunrise.

3, the water heater is not long-term use, re-enable operation with 2.

4, the installation of solar water heaters fixed later, do not secretly change its structure and installation, do not move, especially water in the water tank ban mobile case.

5, around the solar water heater should not put debris in order to eliminate the impact of the vacuum tube hazards.

6, regular inspection vent to keep them open.

7, being careful not to damage the tip portion of the lower end of the vacuum tube!

8, the selection of a user auxiliary heating device, to ensure the water in the tank for more than 80% can be used, to prevent dry heating.

9. After the water heater is installed fixed, non-professionals do not easily move, uninstall, to avoid damaging critical components.

10. winter should prevent the cracking pipes, and to ensure the smooth flow of the exhaust pipe, the best night of hot water will run out in the morning, feed cold water.

11. The use of the public in the summer food should choose water in the morning and evening, around noon, water in hot weather, there will be burst pipe cold

12. vacuum cleaned regularly, pay attention not to damage the tip portion of the lower end of the vacuum tube.

13. The public should be checked annually for solar water heater to see if the tank leaks, whether aging parts, collector for damage, rust and other stent is found that the problem should be timely replacement and maintenance, it is best maintained by a professional installer complete .

14. The installation site should also choose the location of the building in less than lightning or less, conditions can be installed lightning rod to avoid the lightning hazard.

15. After the evening bath, if the water heater tank and half 70-degree water, in order to prevent excessive heat loss (the less water, the faster the heat loss), but also the water temperature according to the weather forecast the decision on the amount of water. Tomorrow sunny day, the water is full; rainy days, the two-thirds water.

16. The hot and cold water control: water regulating steps: first open the cold water valve, appropriately adjusting the flow of cold water, and then open the hot water valve is adjusted until the desired bath temperature. In addition, the amount of cold water can be determined empirically according to weather conditions, do not pay attention to head toward the body, to avoid scalding.

17. Wind measures: solar water heater parts and reliable connection, wind performance depends on its mounting method.

18. Do not use vacuum tubes. Vacuum tube solar water heater is the core component of solar water heater is the "heart." Its quality is directly addressed. Given the performance of the entire water heater. Performance by the vacuum coating technology and cleaning, coating, vacuum pumping influence, sealing and other processes and the like.

19. insulation. Solar water heaters, hot water production during the day and stored in a storage box, if the insulation performance of the insulation is not good, overnight, rainy days can not be used, or not used. Solar water heater insulation caused by poor performance is largely due to the insulation layer, insulation is good or bad determines how much hot water heater temperature level and the amount of hot water. Good insulation imported raw materials, such as polyurethane low thermal conductivity, high temperature; automatic temperature thermal process uses high pressure quantitative foaming, and high temperature aging treatment, high thermal insulation performance and stable and lasting.

20. Currently, most solar water heater manufacturers have said the water tank is stainless steel. Also stainless steel, but stainless steel and nickel-chromium is very different. Good solar water heater with high chromium high nickel stainless steel liner, liner ensures durable, strong corrosion resistance; inferior interior use more low grades of stainless steel, is substantially free of nickel, corrosion resistance is poor, short life.

21. Install. Solar water heater installation requirements are very high, professional installation of its winter-use basis and guarantee.

22. Install the electric heater should be original production, so the quality is reliable, but if it is replaced with a seller of cheap low-end electric heater, it is difficult to guarantee their life.

23. The power line quality is also very important, it is best to do outdoor sunlight and wind and rain proof process, namely the power cable with PVC pipes or other pipelines sleeve as well, preferably with power plug leakage protection function, this is more safe and reliable.

24. In the summer, high temperature inside the tank when the water temperature is above 75 degrees, it is easy to produce scale, so the summer should at any time with the use of water, so the water temperature will decrease in time, reduce the scale of production, to improve the collection efficiency.

25. If the weather is bad, mainly the tank water temperature, the water temperature rises by electrical heater, but be aware that water should be added to the tank according to weather conditions, when the weather is bad, you can add half , so time will be quickly heated by electricity, generally one half of the water bath is no problem, people take a bath temperature of about 42 degrees.

26. According to local water conditions, a few years to do the best for the proper cleaning process scale, in fact, very simple, the tube removed, the scale tube drained, and then repeated by adding clean water rinse several times you can a.

27. Some service-name companies often recruit workers consisting of four "guerrillas", there is no formal training in a hurry posts, these people either do not understand the design of piping, water heaters and other fixed body of expertise, but do not understand the latter part of maintenance products maintenance problems caused abound direct impact of solar water heaters "standard life."

28. Do not check maintenance of electric heating is very dangerous, with a long leakage trouble. Out of the water are charged. Recommend the use of air source heat pump water heater

29. The use of solar water heating electric heating must first, and then after the power off in the bath, do not take a bath while electric heating side, dangerous.

30. The solar water heater heating water most are secondary, mainly because of the water heater used for many years, in part, Chen Shui (ie, did not run out of water), there will be dirt accumulation, which is a lot of harmful substances.

31. Even if the water heater has reached 100 degrees, the heating time is very long, in the process, there will be a lot of nitrite generation, and nitrite are the major threats to human health, the family of the secondary experts do not recommend drinking distilled water, not to mention such a solar water heater in the hostile environment of the container it.

32. The regular cleaning of solar water heaters.

33. Effective antifreeze, so there is always a way down pipes from heat, add insulation, effectively freezing. In the northern winter, many people also use the indoor water heater valve slightly open, dripping down approach to antifreeze.

34. long with water on the lower floor of the user, the used water is actually cold water pipe (solar water heater inside the water stays in the pipes formed after cooling), especially in the northern winter, the low outside temperature sometimes achieve the following -25 ℃, water pipes and down the road in the cool ground quickly, if six floors, the first floor each time a user need to let go of a basin of cold water, especially waste, if you like some frequent use;

35. Note feed cold water time.

36. Depending on the weather conditions, the decision on the water to ensure proper water temperature bath.

37. Has regularly check the water heater pipes, vents and other components work properly.

38. The severe air pollution or wind, dry areas regularly wash vacuum.

39. A solar water heater is installed in front, next to the water heater should first lightning rod roof effectively heightening to more than half a meter above the top of the water heater, and water heater tank must be effectively grounded.

40. Indoor outlet must be connected to the ground potential.
Do not use water heater 40. thunderstorms.

41. At the time of installation, the solar roof and firmly fixed together, can be anti-typhoon. Typhoon, to ensure the full solar water, in this case, better wind performance.

42. winter without solar water off, the water tank is the heat capacity, which means that the solar water tank is a certain heat, the greater the amount of water, heat capacity, the more ice can delay speed. If you let the water out, the water in the tube is not put out, the heat capacity is smaller, easy to freeze.

43. The use of solar water heaters in winter: low intensity of sunshine, sunshine time is short, and low ambient temperature, it is possible to reach the day, the day is expected to feed cold water temperature at this time may be appropriate to control the amount of water in the water tank, or start the electric auxiliary systems, where necessary, or gas auxiliary systems.

44. The installation of solar energy, the choice of good quality will extend the life of vacuum tubes and electric heating.

45. In direct sunlight or sunlight too little time, and excessive water can be used in urgent need of hot water electric heating.
