In life, electric water heaters bring convenience to people in the shower. Electric water heaters officially provide the following four methods to solve the maintenance and cleaning of electric water heaters. It is better to go to regular shopping malls to buy brand products. Most of the products purchased from regular shopping malls or specialty stores have quality assurance, good performance, professional installation and after-sales service guarantee. How to maintain the electric water heater? How to use and maintain the electric water heater: How to maintain the electric water heater First of all, you need to choose a suitable installation environment 2. The installation environment should be a place that is relatively dry and ventilated, without other corrosive gases, and where water and sunlight cannot be in direct contact; 3. There must be a reliable floor drain indoors to facilitate drainage; 4. The power supply must have a reliable grounding or Anti-leakage protection device; 5. The water pressure of the electric water heater is normal, generally not more than 0.7mpa. If the water pressure is really too high, a pressure reducing valve must be installed in front. How to maintain: 1. Regular inspection, cleaning and maintenance. Domestic gas water heaters are generally cleaned once every 6 to 8 months to reduce the emission of harmful substances and save gas. Regularly clean the inner tank. When used for a long time, the trace impurities and minerals contained in the water will precipitate for a long time. If it is not cleaned regularly, it will affect the water quality and service life. The inner tank is cleaned every six months. The cleaning method is to cut off the power first. , close the water inlet valve, then open the water outlet valve, turn the drain switch on the safety valve 90 degrees counterclockwise, and naturally drain the water and sediment in the water heater. Then rinse with tap water. After cleaning, restore the drain switch to its original position, and pay attention to power on after it is full of water. 2. Regular inspection at least once a year to carefully detect and eliminate safety performance and other potential hidden dangers; users who do not turn off the power supply of the water heater all the year round should always check whether the water heater is normal, and if there is any abnormal situation, it should be sent for maintenance in time point repair. When the water heater is in normal use, the thermostat and heater should be replaced every three years at the service point. Replace the expired water heater in time. Electric water heaters should be inspected and maintained once a year, because there are more or less impurities in the water. After a period of time, the heating body will be easily corroded by alkaline substances in the water, which will also affect the safety performance of the electric water heater. After the electric water heater is used for a period of time, scale is easy to accumulate on the heating pipe, which seriously affects the heating efficiency and consumes electricity. Therefore, the general electric water heater needs to maintain the heating pipe regularly. In addition, the inner tank of the electric water heater should be cleaned every six months. The cleaning method is to first cut off the power supply, close the water inlet valve, then open the water outlet valve, and rotate the drain switch on the safety valve 90 degrees counterclockwise to naturally drain the water in the water heater. Precipitate. Then rinse with tap water. After cleaning, restore the drain switch to its original position and fill it with water before powering on. 3. When not in use for a long time, turn off the power supply and empty the water storage in the inner tank; if the water output of the shower is reduced, it is necessary to clean up the blocked debris in time to ensure that the outlet is unobstructed, which is helpful to prolong the service life of the water heater. If you do not use the water heater for a long time, you should first unplug the power plug to keep the water heater in a power-off state. This is mainly for safety. If you do not use it for a long time, but keep the water heater in working state, it will cause the components in the water heater to accelerate aging and shorten the power consumption. The service life of the water heater 4. Never replace the parts on the water heater by yourself. Do not repair by yourself after failure. Contact the maintenance unit in time. After the maintenance personnel arrive, the public is advised to check the maintenance warranty certificate issued by them. In order to ensure the normal use of the water heater, the safety valve needs to be maintained at least once a month to ensure the normal pressure relief of the safety valve.
