How to maintain an electric water heater? Electric hot water
In life, electric water heaters bring convenience to people in the shower. The following four methods are coups to solve the maintenance and cleaning of electric water heaters. It is best to go to regular shopping malls to buy brand products. Most of the products purchased from regular shopping malls or specialty stores are guaranteed by quality, good performance, professional installation and after-sales services. How to maintain an electric water heater? How to use and maintain an electric water heater:
How to maintain an electric water heater first requires selecting a suitable installation environment
1. The wall installed on the hook must be a solid wall with a thickness greater than 10cm, and it is best to install a firmer bracket when installing with a capacity of more than 80 liters;
2. The installation environment should be relatively dry and ventilated, free of other corrosive gases, and where water and sunlight cannot come into direct contact.
3. Reliable floor drains are required indoors to facilitate drainage.
4. The power supply must have a reliable grounding or leakage protection device.
5. The water pressure of the electric water heater is normal, generally no more than 0.7 MPa. If the water pressure is indeed too high, a pressure reducing valve must be installed in front.
How to maintain an electric water heater:
1. Regular inspection, cleaning and maintenance. Household 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 liner. When used for a long time, after the trace impurities and minerals contained in the water have settled for a long time, if not cleaned regularly, it will affect the water quality and service life of the effluent; the liner is cleaned every six months. The cleaning method is to first cut off the power supply, close the water inlet valve, and then turn on the water outlet valve. Rotate the drain switch on the safety valve 90 degrees counterclockwise to naturally drain the water and sediment in the water heater. Then clean it with tap water. After cleaning, restore the drain switch to its original position, and pay attention to the full water before powering on.
2. Periodic 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 year round should always check whether the water heater is normal. If there is any abnormality, the situation should be sent to the maintenance point for repair in time. In the case of normal use of the water heater, replace the thermostat and heater at the designated maintenance point every three years. Replace the overdue water heater in a timely manner. Electric water heaters should be checked and maintained once a year, because there are more or less impurities in the water. After the heating body is used for a period of time, it is easy to be 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 regular maintenance of the heating pipe. 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 and sediment in the water heater. Then clean it 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 tank; if the water output of the shower is reduced, 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 the water heater is not used for a long time, the power plug should be unplugged first to keep the water heater in a power-off state. This is mainly for safety. If it is not used for a long time, the water heater will be in a working state, which will cause the components in the water heater to accelerate aging and shorten the service life of the water heater
4. Never replace the parts on the water heater by yourself. Do not repair it without permission after a failure. Contact the designated 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.
How to maintain the electric water heater requires attention to the use of precautions
1. When not using the water heater for a long time, please turn off the external main power switch.
2. The water outlet must be opened when filling the water, and the water can only be checked whether the water is full after the air in the liner is completely discharged;
3. Regularly remove dirt from the shower and water barrier to ensure smooth water outlet and help prolong the service life of the water heater.
4. Do not use acidic or alkaline cleaning liquid to scrub the shell of the electric water heater. When scrubbing, use a neutral cleaner. After wiping, use a damp cloth to gently dry it. When cleaning, turn off the incoming power supply first.
5. The power supply must be cut off before emptying.
6. Do not spray water on the air switch or fuselage during use to avoid moisture in electrical components.
7. For closed installation, the water inlet valve must be open during heating.
8. If it is suspected that the water in the water heater may freeze, it is forbidden to connect the water heater to the power supply.
9. In the case of high water pressure, the pressure relief valve may have water droplets dripping, which is a normal phenomenon. It is strictly forbidden to block the pressure relief port. You can use a diversion pipe to lead to a safe sewer and ensure communication with the atmosphere. If the water pressure of the tap is too high, it is recommended to add a pressure reducing valve away from the water heater.
10. When opening the valve, do not direct the water outlet towards the human body.
11. The water heater outlet shall not be connected to any water valve or shower that is not provided by the company, so as not to affect the bathing effect.
12. If the water heater malfunctions or malfunctions, the seller should be promptly contacted and sent to the maintenance point for repair.
13. If the machine is installed for the first time or in case of water outage, pay attention to filling it with water before powering on.
14. Do not disassemble the machine yourself and replace the parts on the water heater.
