The scale in the water heater is easy to breed bacteria on the one hand, causing various skin diseases, on the other hand, reducing the efficiency of the water heater, and may even cause an explosion. So how do we remove scale?
1, electric water heater
Electric water heaters belong to professional equipment. It is best to ask professionals to clean them. If you clean yourself every six months, you can clean them once. The cleaning steps are not complicated and you can do it yourself. But be sure to pay attention to safety.
First, unplug the power outlet. It is best to turn off the main power supply inside the house and close the inlet and outlet valves.
Then, unscrew the hot water port nut and block the hot water port by hand (be sure to ensure that there is no hot water in the water heater to prevent burns) and prevent the water from flowing out of the water heater. At the same time, unscrew the chiller nut and connect the hose (the shower pipe) to drain the water until the cold water outlet has no water. The 50L water heater drains for about 1 hour.
Finally: remove the hose connected to the cold water port, connect the hose to the hot water port, connect the water to the faucet, open the faucet for 1 minute, and plug the cold water, let the cold water put in the inner liner for a while, then Open the chilled drain and repeat it several times until the drained water is clean. Screw on the nut of the cold water port and hot water port, open the triangle valve, and open the hot water of the water heater tap. After the water flows out, close it.
2, gas water heater
In the gas water heater, it is actually a heating tube. When cleaning, just remove the water heater and pour the detergent from the water inlet and keep it for a while. Commonly used cleaning agents can be mixed with white vinegar and water 1: In fact, the detergent dilution solution is also good, and there is a special cleaning agent sold in supermarkets.
