Household electric water heaters, when we use them, we generally set a temperature.
For most households, once the temperature is set, it may never be adjusted again.
However, many friends do not pay attention to the temperature set by the water heater at our home.
Among them, the most common water heater setting temperature is 70°C, and some are 65°C.
However, it wasn't until the maintenance master said that I realized that there was such a big difference between 70°C and 65°C.
So, is the electric water heater set to 65°C or 70°C? It wasn't until I washed the water heater twice a year that I realized the difference, and it turned out that I had been wrong all along.
What are the problems of a large amount of limescale in the water heater?
For storage type electric water heaters, there is a common problem, that is, the production of scale.
Especially the water quality at home, if it is hard, you will find that the water heater has a lot of scale.
And these scales will adhere to the inside of the water heater liner.
As time goes on, there will be more and more limescale.
Then, at this time, the scale inside the water heater will generally bring the following problems.
(1) - Electricity consumption
The first problem caused by the increase in scale inside the electric water heater is the consumption of electricity.
If we have observed the electric water heater at home, we will actually find that it consumes electricity.
For example, if you buy a new water heater and boil it for two hours a day, it may be 5 kilowatt-hours of electricity.
However, if the water heater has been used for several years, the same two hours a day can consume six or seven kilowatt-hours of electricity.
The reason for the increase in power consumption is the increase in internal scale:
(1) Scale affects the heat dissipation of the heating rod. Because the exterior is covered with a layer of limescale, there is a scale barrier between the heating rod and the water, so the heating efficiency is reduced.
(2) The thermal insulation effect will gradually decline. Because after the scale increases, it will also affect the insulation of the inner tank to a certain extent, so the water heater will often be heated repeatedly.
(2) - The water flow is small
The second problem caused by the increase of scale inside the electric water heater is the small flow of water.
Because with the appearance of hot water, some limescale will slowly appear inside it.
At the beginning of the appearance stage, the scale actually moves with the water to a certain extent, and then rests.
In this process, the scale slowly adheres to the inner wall of the electric water heater, the water outlet and the shower.
At this time, we will find that the water flow of the electric water heater at home is not as big as before.
The root causes of the reduced water flow are as follows:
(1) The water outlet of the water heater is blocked by scale, and the water flow becomes smaller. In fact, to put it bluntly, the water outlet becomes smaller, resulting in a gradual decrease in water flow.
(2) The inside of the shower is scaled, resulting in a smaller water flow. In fact, many friends will find that after using the shower for a few years, there is a lot of scale in it, and even some of the water outlets are blocked.
(3) - Replace the magnesium rod
The increase in limescale in the electric water heater will also increase the frequency of replacing the magnesium rod.
At this stage, most electric water heaters are installed with magnesium rods.
In fact, the most fundamental function of magnesium rod is to reduce the appearance of scale to a certain extent.
Its function is to use the magnesium rod to eliminate calcium ions and avoid the formation of scale.
In the process of this work, the magnesium rod will be consumed.
Therefore, if there is a lot of limescale in the electric water heater, the following conditions will generally be found:
(1) The consumption of magnesium rod is serious. If you turn on the water heater and take out the magnesium rod, you will find that the magnesium rod consumption is very serious, and even some magnesium rods cannot be used.
(2) It needs to be replaced regularly. If there is a lot of scale, it is recommended that you generally check the magnesium rod once every two or three years. At this time, it was found that the magnesium rod may need to be replaced.
(4) - Skin allergies
The increase in limescale in electric water heaters can also cause skin irritation.
In fact, this is also an important reason why many friends do not choose storage electric water heaters.
Because for storage electric water heaters, there is water inside them, and there will be repeated heating problems.
Another point is that there is a lot of limescale adhered to the inside.
Combined, these problems can lead to poor water quality.
Especially for storage type electric water heaters, if they are not used for a period of time and then continue to use them, the problem of releasing water is even greater.
For these problems, it may have the following impacts:
(1) After taking a bath, the skin is dry and itchy. In fact, this is a typical manifestation of skin allergies. Bacteria and fungi grow in the water, which causes itchy skin after bathing.
(2) After taking a bath, the skin is dry. Moreover, when washing, I always find that the water is oily, and I always feel that I can't wash it clean. In fact, this is also a manifestation of poor water quality.
What is the difference between an electric water heater setting 65°C or 70°C?
The above introduced to you the various problems that will occur when scale appears inside the electric water heater.
There are many reasons for limescale in electric heaters.
There is a problem involved in this, that is, the problem of setting the temperature of the electric water heater.
To this end, we will answer the difference between the setting of 65°C and 70°C for electric water heaters through the following aspects.
First of all, we need to figure out what factors are related to the generation of scale.
In the cognition of most friends, the production of limescale at home is related to water quality.
Indeed, this point is a prerequisite for scale, that is, if the water quality is too good, there will be more scale.
However, you will also find that there is a situation that cold water will not appear limescale.
Scale is only formed when the water is heated.
Therefore, the generation of scale in the water heater is caused by a combination of the following two reasons:
(1) The water quality inside the water heater is too poor. This kind of water quality is generally on the hard side. For this water, if we heat it, we will find that there will be a lot of scaling.
(2) The increase in temperature. Limescale is only formed when the temperature rises. Therefore, it must be affected by the temperature or not. At room temperature, there is almost no limescale.
Therefore, it can be seen that the scale of the water heater is not only affected by the water quality but also by the heating temperature, which is caused by the combined effect of the two.
In fact, the biggest difference between setting 65°C and 70°C is the amount of scale generated.
Through the above introduction, you can also find that as the temperature rises, the scale generated is more and more.
The increase in scale in the water heater can be judged by some states.
For water heaters, all we can feel is that the water flow becomes smaller and the heating is slow.
All in all, it's the difference in fouling speed.
At 70°C, the rate of scale is generated faster than at 65°C.
In fact, this means that the higher the temperature we set, the faster the scale will be generated inside the water heater.
For this point, after comparison, you will find that the higher the temperature setting of the water heater at home, the dirtier the water coming out of the cleaning water heater.
How can I reduce fouling in my water heater?
Through the above introduction, the impact of scaling inside the water heater is indeed great.
So, for living at home, you should really learn some ways to reduce scaling.
And for the way to reduce the scaling of the water heater, there are actually many ways. Together, it is to treat water quality and make rational use of water heaters.
To this end, I personally recommend the following three methods to everyone, you can learn about them.
In fact, this is the central water purification.
The tap water that enters our home is softened and then used so that there is much less fouling.
Of course, if we think that the price of central soft water and central water purification is more expensive, then we can actually install a small water softener.
Installing a scale inhibitor is one of the easiest, most cost-effective, and most convenient ways to do it.
Scale inhibitor, we can choose to install it at the inlet of the water heater.
Scale inhibitor, we can take a look at the specific model and specifications. It's about four or five hundred yuan to buy one, and you can install it yourself, but the effect is still very good.
Because the simplest function of a scale inhibitor is to soften the water. Although it cannot be achieved without limescale, it can reduce a lot of limescale to a certain extent.
For domestic water heaters, many families may habitually set the temperature to 70°C.
However, as mentioned above, the higher the temperature setting, the faster the scale will be generated.
Therefore, for household electric water heaters, the lower the temperature setting is the better, under the conditions that meet the conditions of use.
For the temperature setting, you can refer to the following methods:
(1) For frequently used water heaters, if the water consumption is relatively large, the temperature can be set at 60°C to 65°C.
(2) For those who use less hot water, I personally recommend that we generally set it to 50 °C, which can basically meet our needs.
(3) Rational use of capacity increase. If the temperature is low, you may be worried that you will not have enough water. Therefore, you can choose the one that has the effect of increasing volume. For example, there are 10 times 12 times, so that the requirements of hot water can be met.
Written at the end of the article
Water heater, which we use every day. However, most homes are probably sticking to a wrong method of use, always setting the temperature to the highest, always worrying about not having enough hot water.
In fact, using a water heater in this way will increase the burden on the water heater and will bring a lot of problems. Therefore, in the article, I have introduced some correct ways to reduce limescale in water heaters, and I hope you can understand it. This makes our water heater last longer and is more user-friendly. #头条创作挑战赛#
