There is a shop called Household Appliance Refrigeration Maintenance Center at No.12, Courtyard, No.157 Dasha East Road, Huangpu District, Guangzhou, where beautiful water heaters can be repaired. The fees charged are relatively affordable and the service attitude is very good! When using the water heater, you should pay attention to the following points, so that the water heater can be used for a long time!
1. Carry out system blowdown on a regular basis to prevent pipeline blockage; And clean the water tank to ensure the water quality is clean. When discharging sewage, as long as the water inflow is normal, just open the sewage valve until the clean water flows out of the sewage valve.
2. Regularly remove the dust and dirt on the transparent cover plate of the solar collector, and keep the cover plate clean to ensure high light transmittance. Cleaning work should be carried out in the early morning or evening when the sunshine is not strong and the temperature is low, so as to prevent the transparent cover plate from being shattered by cold water.
3. Pay attention to check whether the transparent cover plate is damaged, and replace it in time if it is damaged.
4. For vacuum tube solar water heater, always check the vacuum degree of vacuum tub——-titanium getter of vacuum tube turns black, it indicates that the vacuum degree has decreased and the collector tube needs to be replaced.
5. In addition to cleaning the vacuum tube, the vacuum tube solar water heater should also clean the reflector at the same time.
6. Patrol and check the pipelines, valves, ball valves, solenoid valves and connecting hoses for leakage, and repair them in time if any.
7. If the heat absorption coating of the heat collector is damaged or falls off, it should be repaired in time. All supports and pipelines shall be painted with protective paint once a year to prevent corrosion.
8, to prevent stuffy sun. Stopping the circulation of the circulation system is called stuffy sun, which will cause the internal temperature of the collector to rise, damage the coating, deform the insulation layer of the box and break the glass. The cause of stuffy sun may be the blockage of circulating pipeline; In the natural circulation system, it may also be caused by insufficient cold water supply and the water level in the hot water tank is lower than that in the upper circulation pipe; In the forced circulation system, it may be caused by the stop of the circulating pump.
9, all-weather hot water system installed with auxiliary heat source, should regularly check whether the auxiliary heat source device and heat exchanger work normally. For the auxiliary heat source is heated by electric heating tube, the leakage protection device must be reliable before use, otherwise it cannot be used. For the heat pump-solar heating system, it is also necessary to check whether the compressor and fan of the heat pump are working normally, and troubleshoot any part in time.
10, when the winter temperature is lower than 0℃, flat system, should empty the water in the collector; If the forced circulation system with the function of antifreeze control system is installed, it is only necessary to start the antifreeze system without emptying the water in the system.
