If the water heater is not clean, then we wash it in vain, so it's very important to clean the water heater on time. If you let the door-to-door master clean it, the price is relatively expensive. In fact, you can clean it at home, so how do you clean the water heater at home?
How much is the water heater cleaning
If you ask a professional to clean the water heater, it's usually about 60 to 100 yuan. If you want to be more specific, you can call the water heater maintenance technician to ask for the specific price.
If you can, it is recommended to wash by yourself. The water heater cleaning is very simple.
Water heater cleaning method
1. Preparation: power off and drain. Let's talk about water discharge: close the triangle valve of the water inlet pipe (to prevent water from entering the water heater again) and open the water discharge valve of the water inlet pipe (cold water). At this time, the hot water pipe should be opened at the same time, or the water will not be discharged. The drainage process is very long-lasting, depending on the impurities in the tank. If there are too many impurities blocked, the time will be longer.
2. Remove the cover on the side of the inner tank of the electric water heater, and you can see a hole.
3. Remove the heater gasket, heater and temperature controller in turn.
4. Use a container to clean the bottom of the tank.
5. According to the reverse installation process of disassembly, the important thing is that the heater must be installed well and tightly pressed with the sealing ring to prevent water leakage. In addition, the temperature adjusting knob of the plastic cover should correspond to the knob of the temperature controller.
6. Close the drain valve, open the water inlet valve and the hot water valve until there is water flowing out of the hot water pipe, then connect the power supply, and set the temperature control knob to the appropriate position.
How often do you wash the water heater
It is easy to produce scale when water heater is boiling, and it is easy to block water pipe of water heater. It must be cleaned once a year and cleaned once a year. Otherwise, the water heater will be very dirty, so bathing does not achieve the effect of bathing, and the water heater is prone to failure.
Harm of water heater not cleaning
1. The thermal conductivity of scale is much lower than that of metal, and the thermal conductivity of metal steel pipe is 6-1000 times of scale; scaling in vacuum pipe will seriously affect the temperature of hot water; hard scale can reduce or even fail the thermal energy conversion rate of solar energy, which is also the reason for the decrease of water temperature and water supply of solar water heater.
2. There are many chemical components in the scale. The long-term sedimentation and accumulation make the harmful substances in the water increase continuously, which may lead to skin allergy.
3. Slime, microorganism and bacteria also generate a lot of harmful substances in the long-term continuous renewal and alternate reaction, which can cause a variety of skin diseases. Some women and children sometimes feel itchy or red spots after bathing.
