Solar hot water system maintenance and management
Net appliance industry has been widely used, but users often do not know the usual maintenance and general fault repair. Sometimes a small fault on the system could not be used. This paper describes the solar hot water system (device) and routine maintenance, common faults, causes and repair methods.

Green energy saving solar water heaters
Recent years the rapid development of China's urban and rural construction, "green building" and "ecological communities" north and south the land covered by the concept of a moment, was of concern to all walks of life. Hot water usage is a measure of people's living standards and an important symbol of social civilization one. From environmental protection, energy saving, use of green energy and other factors to consider, promote the use of residential solar hot water system to provide hot water for the residents has been the inevitable social progress. Solar water heater in the research and development, commercial production, market development and has already made significant progress, flat plate collector, glass vacuum tube solar collector, different models and different specifications of solar water heaters have been widely used in general.
Solar water heating system (device) is very important maintenance work, it is directly related to the hot water system (device) of the collector efficiency and service life. As the saying goes: "third building, seven Management" is justified. Maintenance is not complicated, the key is to long-term adherence, regular.
1, solar water heating systems (devices) and maintenance work, including the following:
1, the sewage system regularly to prevent pipe blockage; and cleaning the water tank to ensure water quality. Sewage, as long as in normal circumstances to ensure water, open sewage valve, discharge valve to the outflow of fresh water on the line.
2, transparent container periodically remove the sun set on the dust cover, dirt, cover to keep clean in order to ensure high light transmission rate. Cleaning should be done in the early morning or evening sunlight is not strong, when low temperatures to prevent the transparent cover is cold water shock broken.
3, pay attention to check the transparent cover is damaged, if damaged should be replaced.
4, the vacuum tube solar water heater, vacuum tubes should always check the degree of or within the glass tube is broken, when the vacuum tube of barium – titanium getter black, that is, that vacuum to drop, need to replace the collector tube .
5, in addition to cleaning vacuum tube solar water heater vacuum tube, the reflector should be cleaned at the same time.
6, inspection checks the pipes, valves, floating ball valve, solenoid valve, hose and other connections for any leaks in the phenomenon, if any should be repaired in time.
7, the heat-absorbing coating collector if damage or loss shall be repaired in time. All brackets, piping, brushing once a year to protect paint to prevent corrosion.
8, to prevent nausea drying. Stop the cycle of drying the circulatory system called boring, boring sun will cause the internal temperature of collector, damaged coating, so that deformation of cabinet insulation, broken glass, and so on. Nausea caused by the sun may be due to blocked circulation pipe; in the natural circulation of water may be enough cold water, hot water tank caused the water level lower than the circulation pipe; in force may be due to the circulatory system circulation pump to stop working due to .
9, installation of auxiliary heat source, all-weather water heating systems should be regularly inspected and the auxiliary heat exchanger unit is working properly or not. For the auxiliary heat source is electric heating tube before use to ensure leakage protection device must be reliable, can not use. For heat pump – solar heating system should also check the heat pump compressor and fan is working properly, no matter what part of the problem must be timely troubleshooting.
10, winter temperatures below 0 , the plate-type system should be drained of water within the collector; installation of frost control system of compulsory circulatory function, then you can just start freezing system, without emptying the water within the system.
2, solar hot water system repair common faults
Solar water heating systems are generally divided into domestic solar water heaters and solar hot water heating system. Household solar water heater failure is simple, easy to maintain. First solar hot water system there is a common failure analysis, re-heating solar hot water system on specific issues.
