How to clean water heater heating elements from scale. How to descale a boiler at home

One of the most important “enemies” of electric storage water heaters or other devices for heating water, is the scale that forms on their heating elements (heating elements) and the inner surface of the tank.

It is the formation of this hard calcareous layer on the heating element, due to its low thermal conductivity, that increases consumption electrical energy and, accordingly, the time to heat the water.

It is worth noting that a 3 mm deposit of scale on the heating element leads to losses of 5 to 10% of heat. In general, the coefficient useful action water heater is reduced by almost a quarter. In addition, due to the appearance of such a “warm blanket” on the heating element, it quickly overheats and, over time, becomes completely unusable.

Therefore, to extend the life of the heating element and save money on heating water, you should regularly clean the surface of the heating element from scale. Here, there is deliberately no mention of cleaning the walls of the tank from lime deposits.

The fact is that in some cases, limescale on the walls of the tank plays a positive role rather than a negative one:

Firstly, it protects the inner surface of the tank from an aggressive aquatic environment and, as a result, the destructive effects of corrosion. And, secondly, it serves as an additional layer protecting the water heater from heat loss. There are two ways to clean the surface of the heating element from scale:

First way– mechanical. It must be carried out immediately as soon as you remove the heating element from the inside of the water heating tank, before it dries out. Agree, it’s much easier to clean off wet limescale than when it’s already petrified. To do this, you will need a suitable tool, for example, a knife, a wooden spatula or a metal brush, in short, anything that will be convenient for you to clean off the plaque layer by layer.

At the end of the process, for final polishing of the heating element, you can use emery cloth on a cloth base. Remember that the cleaner the heating element, the less heat loss there will be and, accordingly, greater savings of time and money.

Second way– chemical. The current domestic chemical industry produces a huge amount various means, which help get rid of scale from kitchen kettles. A storage water heater is the same as a kettle, only very large, so feel free to use these products according to the instructions on the packaging.

To do this, you will need an enamel bucket or any suitable container with a depth greater than the length of the heating element. If you don’t want to go to the store, you can remember your school chemistry lessons and use any suitable acid to remove scale. At home, we usually store vinegar.

Add a glass of essence to a bucket of water and immerse the heating element in it. To increase cleaning efficiency, the bucket can be placed on fire. In any case, chemical reactions proceed faster in a warm solution.

Some extreme sports enthusiasts clean scale with Coca-Cola or Sprite. They say that Sprite is most effective against scale. In any case, it should be remembered that it is undesirable for chemicals to come into contact with the rubber seals, as this can lead to a loss of elasticity and contribute to the appearance of leaks.

We hope that these, in general, simple tips will help you effectively and correctly carry out preventive cleaning of water heating elements of any appliances you use in your home.

The boiler should be cleaned every few years. If you use your water heater intensively and the water quality leaves much to be desired, you need to wash the product more often. Of course, it’s easier to turn to plumbers for help, but if you want to save money, you can do the cleaning yourself.

Why clean the boiler?

Regular maintenance of the boiler is the key to its long and high-quality operation. Cleaning agents dissolve poorly in hard water, and it also tends to form scale, which is a poor conductor of heat. The heating element, located in the storage tank, is covered with a thin layer of lime over time. It starts to work worse, power consumption increases. If you do not clean the element, scale will settle on its surface and penetrate into all accessible places. Such plaque is not only difficult to remove, it seals the heating element and leads to significant interruptions in operation. There may be no heat transfer at all.

The protection relay is activated and the device turns off. Neglected cases may result in boilers having to be repaired. To prevent this from happening, it is necessary to carry out timely cleaning.

When should cleaning be done?

The boiler needs to be cleaned approximately every two years. Start the process if you notice the following interruptions:

• the device began to heat the water for too long or switched off frequently;
• the boiler makes a loud hissing sound when operating;
• a yellow liquid with the smell of hydrogen sulfide pours out of it.

If you use the water heater at maximum temperatures, you will have to clean it more often (scale and build-up on the tank form faster). To extend the life of the device, heat the water to 60-70 degrees Celsius.

Another good piece of advice - to reduce the number of breakdowns, do not buy water heaters with heating elements made of ferrous and galvanized metals. Such parts are less resistant to rust and do not cope well with heating water.

Give preference to magnetic thermostats.

Drain the water

Before cleaning the boiler, you need to get rid of all the liquid inside it. If the water heater is located directly above the bathtub, you can place a large container under it and drain the water while removing the heating element. Find out if the electric heating device is screwed into the tank - carry out two procedures simultaneously. If in order to remove the heating element you need to unscrew several nuts, it is better to drain the water in advance. If properly connected to the water supply, there should be no problems with cleaning.

1. Be sure to disconnect the device from the mains and close the main water supply tap.
2. Turn off the cold water, turn on the hot water at the nearest faucet and wait until it drains.
3. Connect the tube to the drain fitting, direct it to the sewer, open the tap and drain the water.

There is another option - if there are no taps and drain pipes, empty the tank using Cleaning this method is a long process, so it is better to wait until the water cools down. If there is no fitting, disconnect the tube hot water and place the bucket. Gradually unscrew until liquid flows out.

Preparing for cleaning

Cleaning your water heater is not a very complicated process and can be done on your own. After all the water has been drained, disassemble and remove the heating element. To do this, remove the decorative cover (most often it is secured with screws). In some boiler models, the parts we need are closed plastic panel. It is held on by clamps - just pry the bar off with a screwdriver.

Take a photo of the connection diagram so that you can return everything back after the procedure. Disconnect the wires to expose the thermostat. Get him out.

Scale is the number one enemy of boilers. If you do not periodically clean the heating element, it may become irreversibly damaged. Timely cleaning will save you from wasting money and will significantly extend the life of the device. Carefully remove a heating element. Next to it you will see an annon that protects the insides of the tank from corrosion. See if it's intact. If not, replace the part with a new one.

Cleaning the heating element

The boiler must be cleaned immediately - wet scale is much easier to remove than hardened scale. The bulk will be located at the heating element. There are several ways to clean an element.

1. Remove dirt by hand. Remove the top thick layer of scale from the surface of the heating element with a knife or a stiff brush. Act carefully so as not to damage the surface of the element with sudden and careless movements. Afterwards, you can treat the heating element with sandpaper - the cleaner it is, the better it will work.
2. You can buy a huge number of descaling products in the store. It is better to purchase a cleaning product for electric kettles - its operating principle is the same as that of a boiler. Take any enamel container, add liquid (read the proportions on the package first). Leave it for a while.
3. Instead of ready-made products, you can use the following. Fill a small container with a solution of citric or acetic acid. Place the element in a bottle and leave for a day. To increase cleaning efficiency, place the container with the heating element on low heat (30 minutes).

Cleaning the heating tank

Flushing the inside of boilers is as important as cleaning the heating element. Place a bucket, open the cold water tap and wait until it washes away the remaining scale from the water heater. For convenience, you can remove the device from the wall.

In case of particularly heavy soiling, remove the scale manually. Do not use abrasives or hard objects - this is unacceptable on an enamel surface. Do not touch the magnesium rod; if anything happens to it, you will have to buy a new part. If you cannot remove scale, you must dismantle the device and clean it with chemicals.

After cleaning, assemble and connect the water heater. Remember: all parts must be dry.

Aids

Removing a copper heat exchanger from an indirect heating device is not so easy, but conventional large-capacity models can take all day to disassemble and reassemble. In this case, cleaning the boiler with chemicals will help, without disassembling or removing the device.

Visit the store and buy a product created specifically for such purposes. As an alternative, you can prepare a concentrated solution of citric acid (half a kilogram of acid per 2 liters of water). It doesn't matter what exactly you choose.

To pour the product inside, empty the container by a third through a hot water tap. Connect the hose to the drain fitting and pour the solution through it, while lifting the end of the pipe above the boiler. Leave for several hours. Then drain the solution and rinse the tank, draining the water several times and refilling it again. Connect the device, heat the water and drain it again. The water heater is ready for use.

Cleaning a boiler is a simple process, but it is better not to carry out the procedure alone - water heaters can be very heavy.

• If you use chemicals, make sure they do not come into contact with rubber seals- they may lose elasticity, causing the boiler to leak.
• Double check every operation you perform. The water heater will not work after assembly if done incorrectly.
• Connect and disconnect power only when the tank is full of water.
• When you have finished flushing, fill the boiler with water and wait a while. If the flange does not leak, great, you can use the device.
• If you use chemicals, be sure to wear gloves and a protective mask.

Now you know how to clean a boiler without calling a technician. This is a fairly simple and relatively quick process that any owner can handle. The main thing is to carry out this operation in a timely manner so that the device serves you for a long time. Remember: professional boiler repair is a costly process.

Over time, an electric water heater begins to work worse. It heats water more slowly and weakly, consumes more electricity, and may even fail. In such cases, you should not rush to call a specialist or buy a new device. First you need to try cleaning the water heater, and most likely it will work as before.

What causes a water heater to become dirty? Many of its parts are in constant contact with tap water, so many chemicals are deposited on them. Most of all, such deposits accumulate on the walls of the boiler, as well as on the magnesium element and heating element. Scale prevents the passage of heat from heating parts to the water. Therefore, electricity consumption increases and there is a risk of the heater burning out. The conclusion is simple: if the boiler begins to heat water more slowly, it needs to be cleaned urgently.

How to clean a water heater

For convenience, it is better to adhere to the following cleaning order.

Before working with the boiler, it must be disconnected from the power source. It's more convenient to do this:

• Disconnect the heater and make sure it is not connected to electricity.
• At the bottom of the device (usually there), remove the plastic protective cover. It is attached with bolts, so you will need a suitable screwdriver to remove them.
• Carefully disconnect the wires from the thermostat terminals and from the container itself.
• Disconnect the power cable from the input. After this, you need to insulate the exposed wires.

It is now safe to carry out other work. But before you start cleaning, you need to disconnect the electric heater from the water supply system and drain the remaining water from it.

Scale on the boiler

It's easier to do this:

1. Wait until the water in the tank has cooled completely.
2. Shut off the cold water supply.
3. It is important to open the hot water supply. This can be done on each of the mixers installed in the apartment.
4. Now you can drain the water. To do this, you need to find a suitable hose and put it on for release. check valve. Place the other end of the hose in an empty container or toilet. Next, press the valve shutter and pour out the water.

Some heaters do not have a relief valve. This feature is more common among Ariston brand models. In this case, to drain the water, you need to unscrew the valve itself. Before doing this, you need to install a container under it, otherwise you will have to collect water from the floor.

Before cleaning, you need to dismantle the heating element. Without this, it is impossible to get to the inside of the boiler. On all models of heaters, the heating element is fixed in a similar way. To remove it you need to unscrew the nut that is located at the output of this part. After this, the heating element, metal plate and seal can be easily removed.

Cleaning electric water heaters

The cleaning process is very simple. Scale is removed from the walls of the tank and other parts using a regular rag. For greater efficiency, remove the removable water heater and wash it with water.

Boiler flushing

Particular care must be taken to remove plaque from the surface of the heating element. If you press hard, you can deform its structure. Sandpaper or a metal brush is suitable for cleaning it.

It happens that the heating element cannot be cleaned. Severe contamination usually appears if the device has not been cleaned for more than two years. In this case, only replacing the heating element with a new one will help. It is worth carefully choosing a new part; it must be exactly suitable in size, power and method of connection to the main device.

When cleaning, you need to check the magnesium anode. It should be replaced if it is worn out and becomes less than 20 centimeters.

The water heater can be installed back according to the diagram below. All these steps must be performed in reverse order. It is advisable to check all connections for leaks after installation.

So that cleaning the water heater does not result in its breakdown, it is worth remembering:

• Do not remove scale from inside the boiler using sharp or hard objects. They can scratch the enamel coating and the tank will begin to rust.
• It is better not to touch the magnesium anode with bare hands.
• All wires must be connected correctly. Applying voltage can only be started after assembly has been completed and the container has been filled with water.

After installing the boiler, you need to observe its operation. And also pass 50 to 100 liters of heated water through it to wash the inside.

Do-it-yourself cleaning of water heaters from odor inside

Many owners of water heaters notice over time that the heated water begins to smell terribly. This unbearable smell may have several reasons:

1. Dirty water is supplied to the boiler. If there are a lot of foreign impurities in the water, especially hydrogen sulfide, it emits bad smell.
2. There are specific bacteria and fungi in the tank. Such living creatures are born in the limescale deposits on the walls of the container. As long as there are not many microorganisms, the smell of the water does not change. But over time, their number increases, and the water begins to stink.
3. Cheap or damaged water supply. Low-quality tubular plastic transfers its chemical odor to the water. And old metal water pipes are ideal for the life of bacteria and fungi.

Water with hydrogen sulfide is impossible to smell

There is a way to determine which of these cases occurs:

1. Run cold tap water for 5 minutes. Then place a clean bottle under the stream and close it after filling. After half an hour, you need to open the bottle and check the smell of the water. If it smells bad, there is a problem with the pipes or water.
2. If cold water from a bottle smells normal, you need to look for the reason in the boiler itself. To do this, you again need to fill the plastic container, but only from the hot tap closest to the water heater. We wait 30 minutes and smell. If you can’t breathe from the bottle, it means there are harmful microorganisms in the tank.

In order to eliminate the unpleasant odor due to bad water or rusty pipes, you can do the following:

1. Install a filter that removes bad-smelling gases from the water.
2. Complain to the SES about low quality tap water.

In the first case, you don’t have to wait for someone to come and fix the problem. Therefore, if you can’t stand the smelly water, it’s easier and faster to install a filter.

Problems with microorganisms in the boiler are solved differently:

1. Sterilization of the tank. The water in the boiler is brought to a boil and remains in this state for long time.
2. Removing scale from a water heater (see above). This will destroy the favorable environment for the proliferation of microbes and bacteria.

To prevent smelly water from coming out of the boiler again, you need to follow simple preventive measures:

1. Do not leave water in the water heater when it is not in use for a long time.
2. Periodically descale the tank.
3. It is advisable to install a filter.
4. Pay attention to water quality. If necessary, contact the sanitary and epidemiological station.

What is the difference between cleaning a storage and instantaneous water heater?

Instantaneous water heater

What was described earlier applied to storage-type water heaters. A instantaneous water heater differs from it in its design and operating principle.

IN flow type water does not stagnate in the tank, because there is simply no such capacity. The water heats up as it passes through a narrow tube. It is not stored anywhere, but is served from the tap immediately after heating.

How often to clean a water heater

Manufacturers recommend cleaning your water heater once a year. But water experts do not completely agree with them and say: it depends on the hardness of the water. It is better to stick to the rule - clean the water heater as needed.

1–1.5 years after installation of the device, preventive cleaning should be carried out. If the plaque is more than one kilogram, the next such procedure should be carried out no later than a year later.

We welcome all owners of home water heaters. You are very glad that your water heater works for a long time and properly, but do not forget to care for and clean it. The manufacturers themselves also write about this in the instructions for use of the water heater. If you begin to notice that the water heater does not heat the water well, when heating it makes extraneous noise and the RCD (residual current device) trips. Then you should pay attention to the fact that you need to inspect your boiler and remove scale on the heating element (tubular electric heater) and sediment at the bottom of the tank. The question arises of how to clean the heating element of a water heater with your own hands without resorting to the services of a specialist, we will try to talk about this in our article and training video lesson.

Tubular electric heater (TEH) is an electric heating device in the form of a metal tube filled with a heat-conducting electrical insulator. A conductive thread (usually nichrome or fechrome) of a certain resistance passes precisely through the center of the insulator to transfer the required specific power to the surface of the heating element.

How to clean water heater heating elements from scale

If you begin to notice that your water heater has begun to heat water poorly, and the amount of electricity consumed has increased, then you have problems with your boiler. If you are too lazy to do cleaning and repairs and put everything off until later, then you may end up with more serious problems, including financial costs. But all this can be avoided if your boiler is under warranty, you just need to call the service department. The technician will inspect the boiler on site and give his verdict; perhaps he will start cleaning or repairing it.

For reference: The scale formed on the heating element is a heat insulator. The longer you go without cleaning your water heater, the more it becomes covered in it. Large layers of lime on the heating element do not make it possible to heat water to the required temperature, since its thermal conductivity is very low. If the scale layer is 3 mm, then heat transfer is lost by 15%. Draw your conclusions, gentlemen, your heating element in the water heater heats itself, and in the future it will fail and will have to be replaced.

And if the warranty period has expired, it may still be worth setting aside one day for the water heater and working on it. Perhaps the problem is that you have scale on the heating element and it needs to be cleaned. You can learn how to do this correctly in the video tutorial below.

We disassemble the water heater

For example, let’s take a water heater with a volume of 100 liters. Initially, turn off the electrical power to the water heater from the 220 volt network. Disconnect the cord plug from the outlet. Unscrew the two screws that hold the decorative cover of the water heater. Underneath is everything we need later.

As you understand, under the decorative cover there is the thermostat itself and the heating element. But first we need to disconnect the power cable and contacts from the signal lamp. After we have disconnected the signal lamp stamps, unscrew the screws holding the power cable wires.

At this stage, you should remember which cable is screwed where. If your memory is not very good or you think that you will forget where to connect the wires later. It might be worth taking a photo this part cable connections.

For information, it is worth remembering that the brown wire was connected to the phase, and the blue wire to zero. The yellow-green wire is connected as grounding to the body of the water heater. There is also information on the thermostat itself in the form of zero and line icons.

After you have carefully disconnected the wires and remembered which wire goes where, we proceed to removing the thermostat. But we will need to turn off the water supply. We close two taps at the entrance and exit from the barrel. Don’t forget to place a container below to collect water from the tank. Even if you drain all the water through the tap, you still have water left in the tank.

Removing the thermostat from the water heater

Carefully remove the thermostat from the electric heater housing. Let's slowly begin to unscrew the heating element itself counterclockwise, using a gas wrench. As the lock nut of the heating element is loosened, water will flow out. Do not rush to immediately pull out the heating element, allow the water and scale to come out.

When all the water has disappeared, you can slowly and smoothly pull out the heating element itself. At the same time, you should avoid sudden movements so as not to break it. There may be a lot of scale on it, and therefore it is worth freeing it with smooth movements to the left and right.

While we are cleaning the heating element, we will remove any remaining scale from the water heater tank. To do this, we will need to briefly open the cold water supply tap to the tank. The scale at the bottom of the tank will be washed away and come out. Due to large quantity scale, the electric heater itself may fail.

Now you need to prepare a container where the heating element itself will be cleaned. For these purposes we need a regular plastic one and a half liter bottle. Using a knife, cut off the neck of the bottle, this is necessary so that you can insert the heating element.

Use a knife to remove large pieces scale from heating element. When performing this operation, be very careful and attentive, and most importantly do not damage the metal. You should only remove scale that is ready to peel off on its own.

Prepare a cleaning solution using 1 or 2 sachets of citric acid. Pour the powder and add warm water to the bottle. We release the heating element into the warm lemon solution and begin to shake it. To descale the heating element, it must stand in such water for one day, and if you want to speed up the process, you can periodically refresh the solution and shake it. Under the influence of citric acid, the scale softens and begins to settle to the bottom. A day later, where there was scale, shiny copper flaunts.

Assembling a water heater

When the heating element is cleaned, you can begin to assemble the water heater. Carefully insert the heating element into the tank and tighten the locknut by hand, and then tighten it using a gas wrench. We insert the thermostat into place and slowly open the water inlet and outlet valves of the water heater. Fill with water and check the tank for leaks. In order for air to escape from the tank when filling the tank with water, we will need to open the hot water tap to the mixers.

If there is no water leakage, connect the power cable to the thermostat. We connect the wires the same way they were originally connected. We install the contacts of the signal lamp and screw the decorative cover into place. We plug the cable into the socket and wait for the water to heat up.

Here is a simple procedure for cleaning a water heater heating element. If during the cleaning process your heating element is damaged or it becomes unusable, then it should be replaced with a new one.

To perform such work, you can learn this on our website, but to become a qualified specialist you will need a diploma in the specialty of a mechanic. You can go to study at specialized educational establishments, or you can already start working. Nowadays, without education it is very difficult to find a good job.

How to clean a boiler in 3 ways

You can clean the boiler yourself if you approach this process correctly. You can get true pleasure and a relaxed body from hot water; moreover, a hot bath will relieve your psyche. To fill a person's life hot water, you need a boiler. This human invention, if properly handled, will improve the process of obtaining hot water until it becomes automatic. The key to a long service life of this device is rational and proper care of the item. We must pay tribute to the boiler for the pleasure we experience from taking a bath, and the simplest gratitude would be the regular cleaning of this miracle of technology. The safest, but most expensive way would be to entrust this matter to professionals, but this is too easy. Cleaning this electrical device at home is quite simple. It is enough to be careful and patient, and also to learn about some of the nuances.

Stages of work: how to clean a water heater

Cleaning the water heater is a necessary measure that must be performed at least in order for the device to work normally, that is, the water does not overheat and reaches the required temperature in a minimum period of time. In addition, a repaired electrical appliance has significantly less energy consumption, in contrast to its faulty model.

In order for DIY cleaning to be successful and to begin at all, you will need:

• Disconnect the electric boiler from the network;
• Set of tools;
• Any cleaning agents.

Before cleaning the electric boiler, you need to unplug it and prepare a set of tools

Descaling is a fairly meticulous process, so patience is a good idea. So, armed with everything you need, you can begin dismantling the water heater structure. You will have to open the lid, breaking the seal (you must first drain the water, of course). The water should be drained by attaching a hose of suitable diameter to the drain hole. Special attention you need to pay attention to the heating element, it is thanks to it that the water heater increases the temperature of the water. You should remove the heating element and inspect all parts for damage, corrosion, and other troubles. Inspect the condition of the tank itself.

It is important to pay attention to the electronic part of the boiler; you need it to be well sealed and not let water through, otherwise you will simply destroy your water heater or, even worse, a short circuit may occur.

Almost every boiler is protected from corrosion by a magnetic anode. If you are cleaning it for the first time, you will have to be prepared for not the most pleasant pictures in the inner world of the boiler. When all the “insides” of the water heater have been removed, it may seem that cleaning it is quite easy, but you should not relax. First of all, this concerns chemical cleaning agents. So, for example, chemical agents can easily damage part of the rubber layer that is responsible for the tightness of a vessel with water, so do not be afraid to use folk remedies.

What you need before descaling your boiler

Armed necessary materials, taking a flashlight, you need to carefully examine inner world Electrolux tank. To remove all accumulated scale yourself, it is recommended to use citric acid.

It will be necessary to prepare gloves, cleaning products and a flashlight in advance

So, to clean the boiler from scale, you will need:

• Gloves (so as not to spoil the manicure);
• Flashlight (to avoid problems with visibility);
• Cleaning products (to make the process more effective).

It is enough to dissolve it in a small amount of water and use the resulting solution to rinse the tank with a sponge. Inside, in addition to scale, you can also see a lot of rust; we deal with it in the same way as with scale. Ordinary sandpaper will also help get rid of it. By the way, some manufacturers can add titanium and other impurities to the structure of the material, which significantly improves operation and prevents scale formation. For example, Termex and Ariston can boast of this.

Having scraped off all the scale, washing is necessary, which is designed to rid the contents of the tank of debris by rinsing it.

You should not use a running source of water, as it contains many impurities; it is better to rinse with boiled, slightly warm water to achieve the greatest effect. Last of all water procedures, you must leave the tank to dry.

Methods: how to clean a boiler

The method of rinsing and washing off scale was discussed above. If a lot of scale has accumulated, then you should use a light cloth and wipe the inner surface of the tank carefully, since the material is very sensitive to any damage and stress of this nature. Let's look at the methods of cleaning the boiler in more detail.

There are several ways to clean a boiler, which you can familiarize yourself with.

It is important not to use the following items when cleaning:

• Heavy;
• Solid;
• And tough.

It is also necessary to try not to touch the water heating element (rod), which, if something happens, will have to be replaced with a new one. After all this, you can finish cleaning. But first, it is necessary to again remove the insides of the tank from unnecessary rubbish.

Methods: how to descale heating elements

So, getting to the very heart of the electric boiler installation, you can clean the heating element in several ways. So, the first method is simple and old-fashioned. It is necessary to take some hard object that can be used to clean the surface of the TEN from scale. An iron sponge for washing dishes is ideal. Having picked it up, you need to use physical effort to thoroughly clean the surface of the TEN from the scale that has accumulated on it, then rinse it with water and dry it. The quality of work will depend on its cleanliness.
The next method involves the use of the chemical industry. It is enough to take from the store any product intended for cleaning such parts and, following the instructions, carry out the necessary operation.

You can quickly and easily descale heating elements using both store-bought and folk remedies.

Method three - this concept has already been described a little earlier. So, taking citric acid and by stirring it in water, you can get a solution in which, after standing for quite a long time, all the scale should fall off by itself from the walls of the TEN. If something happens, you can safely help this process manually.

How to descale a water heater (video)

The main and most important ones were indicated a little higher simple ways Clean the water heater from accumulated debris and scale. We should not forget about general rules. When disassembling the boiler, do not forget about the instructions. Remember to seal the tank to avoid damaging the indirect heating elements. It is necessary to remember that the device is connected to the electrical network, the electrical part of the boiler and the storage element. A little luck, self-sacrifice and that's it. Based on this information, you can safely begin cleaning household appliance. It should be remembered that such cleaning must be done regularly and quite often; it must be planned, and not carried out spontaneously, and then only when obvious problems with the device are identified. Proper operation will not only increase the life of the electrical appliance, but will also make you happy with your electricity bills.
