After the water heater is used for a long time, the heating rod will accumulate a lot of dirt, which will affect the water quality. So how to remove the scale of the water heater heating rod?Let's learn together.
Before that, let's take a brief look at the hazards of limescale in electric water heaters:
ElectricityThere is a heating rod inside the electric water heater. When limescale is generated, it is wrapped around the heating rod. The poor thermal conductivity of the scale means that the heat generated by the heating rod cannot be transferred quickly to the water. And then there are two problems: the first is the slow heating speed, the water that can be boiled in 1 hour, and the scale may need 15 hours. The second is the consumption of electricity, because the heating time required is longer.
DirtyThe scale itself is very dirty, and in the process of forming scale, it will also encapsulate the sediment, bacteria and other impurities in the water - so the original color of the scale is white, but the scale in the water heater tends to turn yellow.
As a result, these bacteria will accumulate in the water heater and may flow away with the water at some point. Exposure to ** will make people feel dry, astringent, and itchy. Second, these scales and impurities will fall off, enter the pipes, and block the pipes, especially the relatively thin showers, faucets and other positions.
CorrosionIn the process of generation, scale has a certain corrosiveness to metal. Those **, leaky water heaters, are because the inner tank has been corroded out of the cracks.
Having said all that, how do you clean limescale?
Method 1
Turn off the power of the water heater first, then find the position of its end cover, use a tool to unscrew the screws on it, and remove the cover. Then find the position of the heating rod and rotate it in a counterclockwise direction to remove it. Then soak it in a weakly alkaline solution, wait until the dirt on it has been removed, and then install it.
In addition to soaking the heating rod in a weak alkaline solution to remove scale, you can also use descaling powder, rice vinegar or white vinegar to clean, which can effectively remove the dirt on it. However, after soaking and cleaning, be sure to clean it again with clean water, so as not to leave this cleaning agent on it, which will affect the heating effect of the water heater.
Method two
Try it first
The test machine is normal before the next step, it should be noted that the power supply should be unplugged after the test machine is normal, and then the machine can be disassembled and cleaned.
Drainage
Turn the inlet valve off and then putThe water stop valve opensand connect it to our cleaning hose. Then open the water outlet to drain the water inside, and after draining through, you can open the inner tank.
Dismantle the inner liner
Unscrew the screws with a suitable taper, open the plug cover, remove the ground wire, and place the control panel carefully. (You can take a picture before removing the stitches, so as not to make mistakes when reinstalling) Unscrew all the screws, remove the gland of the heating rod, and take out the heating rod. (The function of magnesium rod: softens water, softens acidic water into weak alkaline water, and reduces the generation of scale.) )
Reload after cleaning is complete. When reinstalling, you must pay attention to the screws to be installed in place, after the heating rod is reinstalled, remember to ensure that the wire is not wet before reinstalling the circuit board. You can wipe it dry with absorbent toilet paper, if you don't absorb the water, the installed circuit board may cause a short circuit.
Note: After connecting, the hot water faucet should be turned on, because the cold water must be exhausted, otherwise the cold water will not be able to enter.
The reload is complete. Replace the cover and plug it in. Everything is normal for the test machine, and the water heater cleaning is completed.
I believe that everyone should encounter a problem when cleaning the bathroom, that is, there are a lot of water stains on the glass partition of the bathroom, and these water stains are very difficult to clean.
Especially on the mirror in the bathroom, as well as on the faucet and other supplies. It is easy to get water stains and limescale, it is uncomfortable every time you see it, and it is very time-consuming to clean it every time.
I used to use glass cleaner to clean him, but the glass partition in the bathroom was too large. Every time you clean it, you have to use one or two bottles of glass cleaner to clean it, which is a waste of money.
Later, I saw that many Internet celebrity bloggers were pushing citric acid descalers, which are not only practical, but also cheap. A large bottle, also food grade citric acid. Compared to other chemical detergents, its safety is satisfactory!
Use it to make your own glass cleaner, and no matter how difficult the glass is, you can use it to clean it. The recipe is as simple as adding 500ml of hot water to a watering can and scooping in two spoonfuls of citric acid. Once cooled, you'll have a bottle of glass washer.
Because dust, scale, and water stains are all alkaline. With acidic citric acid, it can play an acid-base chemical reaction and dissolve water stains and scale. Therefore, spray some on the glass and wipe it with a rag to wipe the glass as bright as new.
And its biggest advantage is that it is safe, citric acid is found in plants and fruits, and citric acid is also used in some food additives. It may not be good to use at first, because it is gentler than some strong acid scale removers, so the effect is not immediate.
But it is precisely gentle so that it does not volatilize harmful gases during use. Although limescale removal is a little slower, it is not too slow. Spray it on limescale areas such as glass, shower heads, faucets, bathroom corners, etc. Let it stand for about 10 minutes, and then gently wipe it with a fish scale cloth to easily remove limescale.
In fact, many descalers react quickly and have high cleaning efficiency, but they will volatilize harsh and pungent gases when used. Citric acid can also be used to remove the scale at the bottom of the kettle because it is safe, add citric acid powder to the water and then boil, after pouring off the boiling water, you can see that the scale at the bottom of the kettle is automatically removed, this is because the scale is alkaline, and the acid-base reaction dissolves it.
You can see that the effect of citric acid descaler after use is really amazing, no matter how serious the scale can be removed!
After having it, all kinds of glass and mirrors at home are free of water stains and scale, and life is more and more comfortable. For housewives with busy housework, citric acid descaler is really useful!
Household citric acid descaler, be sure to look for "food grade"!
Only this citric acid is safe enough. It is used to clean tableware and kitchenware, so that it is more assured.
