How to drain water from a boiler: step by step instructions for water heaters from different manufacturers. How to drain water from a boiler - step by step instructions How to drain water from a boiler

If you use a storage water heater (boiler), uninterrupted supply of hot water in the residential area will be provided all year round, regardless of any repairs. This practical device will be a good helper in a country house where there is no centralized water supply system. Do I need to drain the water from the heater?

There can be many reasons for draining the contents of the water heater, but the main thing is to correctly perform this procedure. Despite the fact that the manufacturer's instructions describe in detail the scheme of how to drain the water from the tank, difficulties often arise, because in some cases it is necessary to dismantle the electric heater.

Water heater device

The device is a system that includes a thermally insulated container and a heat source located inside. Expensive models have a special control unit. With it, you can set the desired temperature. In addition, if there is a control panel, it becomes possible to control the energy consumption, since the device turns on only if the temperature of the liquid has dropped below the desired level.

The main advantages of a storage water heater:

Being a fairly simple device, however, the water heater is durable and economical. Its main components are an internal tank, a heating element and a heating element. True, now they began to produce models with a more complex device. The principle of operation of a water heater is similar to that of a thermostat. In this regard, special attention is paid to the inner lining of the tank.

The household appliance consists of:

metal or plastic case with bracket;
stainless steel tanks (there are tanks covered with a glass-porcelain layer);
a heat-insulating layer separating the tank and the body;
magnesium anode;
tubular electric heater;
safety thermostat;
control unit;
protective valve system;
temperature indicator;
electric cable.

Do I need to drain the water heater?

Cases when the liquid from the boiler must be drained:

In some cases, draining the contents of the water heater tank can even be harmful. Among the common situations that do not require mandatory emptying of the boiler, there are:

Ways to drain water from a water heater

There are four options for quickly emptying the water heater:

How to drain water from the Termex boiler?

Step-by-step instructions for draining water from the Termex boiler:

Using a gas adjustable wrench, close the pipe that ensures the flow of cold liquid into the boiler.
To avoid the formation of a vacuum on the mixer, open a tap with hot liquid.
Wait until the water comes out. The process starts in about one to two minutes.
Close the tap, seeing that the arrow of the boiler points to zero.
Carefully unscrew the nuts in the area where cold water enters. When the nuts are loosened, the liquid must not flow again.
Then take the rubber hose. One of its ends is connected to the supply of cold liquid to the tank, and the other is sent to the sewer hole or bucket.
Disconnect the hot water outlet from the water heater. From this point on, water will begin to flow from the hose.
Finally unscrew the nut that fixes the hot water outlet. The system will quickly begin to fill with air, and the liquid will completely leave the Termex water heater tank. If suddenly the liquid does not drain, you can try to blow the hose.

How to drain water from an Ariston boiler?

First you need to make sure that the water heater is connected to the plumbing system according to the instructions. After checking the connection diagrams of all nodes with the existing boiler and making sure that the installation is correct, they begin to free the water heater from the contents.

The correct algorithm for draining water from the Ariston boiler:

Shutting off the water supply.
Unplug the boiler wire from the socket.
Close the tap from where the cold liquid comes from.
Open a hot water faucet. Wait until the remaining liquid drains.
Do not twist the mixer. This is necessary so that air can enter the tank.
The drain cock is connected to a special hose. He is sent to the nearest sewer hole.
After the drain valve is opened, watch the water drain.

At the end, check whether the liquid has completely drained. Using this ingenuous way to get rid of the Ariston water tank from the liquid, it is important not to forget that the correct connection diagram of the device is important, otherwise you will have to face unforeseen circumstances.

The question of how to drain the water from the boiler sounds quite often today. He is especially concerned about residents of suburban villages who use the device to organize hot water supply. Sometimes there is no other option, especially in the warm period.

But why release the boiler at all? There are two options - for repairs and for winter, if no one lives in a country house during the cold season.

Boiler device

Water heater device

To deal with this issue, you need to know the device of the boiler. This is a stainless steel or enameled container, depending on the manufacturer and model. It includes two pipes:

Supplying water from the water supply network.
Discharging hot water for domestic needs.

Both pipes fit from the bottom of the unit on opposite sides of the center where the tubular electric heating element is installed - the heating element. Pay attention to the length of each pipe. The cold water inlet is short, the hot water outlet is long. Why exactly?

It's all about the laws of physics. Cold water entering the boiler and filling it completely is heated by a heating element at the bottom of the water heater. As its temperature rises, it moves up to the mouth of the long hot water pipe. When the boiler is operating, this process occurs continuously, so that inside the tank the water is located in layers - cold at the bottom, warm in the middle, and hot at the top.

Many may have a question about the security of such a system. After all, water can heat up to a state of steam, which will lead to a rupture of the container. That's right, there is such an opportunity, but the manufacturers have provided for it. Therefore, almost all heaters of this type are equipped with a safety unit that controls the temperature inside the tank. And if it exceeds the limit, the electric current will automatically turn off. There is another element that prevents the boiler from exploding - this is an automatic air vent to release excess pressure. It is usually installed at the highest point of the water heater.

But even these precautions are precautionary, because the water heater tank can withstand a pressure of 7-10 bar. For example, in a city water supply network, the water supply pressure is 4 bar. So the boiler can withstand almost any pressure without problems.

We drain the water

The hot water boiler is a pressure vessel. Therefore, just like that, by opening the valve on any plumbing fixture that uses hot water, and closing the cold water supply valve, it is impossible to drain water from the boiler. A small part of it will merge, which is located above the neck of the long inner pipe. The rest will remain.

Draining water from the boiler

What to do? This type of water heater has 3 holes through which water can be drained:

Cold water supply pipe.
Hot water outlet pipe.
Place of installation of the heating element.

There are more problems with TEN. To remove it, you will have to tinker a lot, removing the electrical part of the device and removing the mounting nut. If this heating element burned out and needs to be replaced, then this is still not the best way. In this way, residual water and sediment that has formed over many years of operation can be drained off.

The best option is through a cold water pipe. Usually, a modern connection is collapsible, where the main pipe elements are attached using an American. This is a threaded coupling with a rubber or plastic gasket. Opening it, you get a free-standing heating unit, not connected to the pipe. But in order to do this, it is necessary to lower the pressure inside the boiler.

Water drain scheme

We turn off the water heater.
Close the cold water supply valve. We are waiting for the water inside the boiler to cool down.
We open hot water in any mixer. We lower it, thereby lowering the pressure inside the tank.
Now you can open the American that connects the boiler to the cold water pipe. There is one difficulty here. Water will be drained under pressure, because it can contain up to 100 liters in a container. In addition, the inconvenient shape of the American does not allow you to put a hose on her. There is only one way out - to substitute buckets or other containers, and to carry out the draining process manually.

Attention! Advice that must be taken into account even at the stage of installing the boiler. After the shut-off valve in front of the American, it is necessary to install a drain valve on the tee. It will ensure the normal discharge of water from the water heater. Just one tap and your problem is solved simply.

How to drain water from a water heater

Very often, a check valve is installed in the pipe in the connection diagram of the boiler with cold water. Its purpose is to prevent water from moving in the opposite direction if, for some reason, its supply has weakened or completely stopped. This sometimes happens in rural areas. So you can drain water through it. This will require a regular screwdriver. The design of the valve has a flag with which you can open the opening of the device.

That is, the American is removed after the valve, the flag opens, and the water begins to descend in the opposite direction. There are spring-loaded valves, then you just have to press the shut-off valve, for example, with the same screwdriver. But even in this case, buckets are required.

This process is not finished. In any case, a small layer of water and sediment remains inside the boiler. To get rid of them, you need to remove the heating element. That is, we again return to this electrical element. The process of removing the heating element is very dirty in the truest sense of the word:

The casing is removed, which covers the connection point of the heating element.
All lead wires are removed from the heating element. Memorize the connection diagram or draw it. You can simply write on paper which wire and what color is connected to the lead wires - fix the color of the wire.
Now you need to remove the cap nut. This is not always easy, and it is important not to overdo it so as not to knock down the thread.
Pull out the heating element. Keep in mind that the remaining water and dirt will immediately pour out from under it.
Flush the tank and check the heating element. If it burned out, then install a new one.

Conclusion on the topic

If you do not want to suffer during such a process as draining water from a water heater, take care of the correct assembly and connection of the heater. A prerequisite is a collapsible pipe connection diagram and the installation of drain valves both at the inlet and outlet. The costs are minimal and the benefits are huge.

It happens that there is a need to leave the house unattended. If this is a dacha, then, as a rule, housing is empty in winter, when the water in the pipes freezes and leads to dangerous breakdowns of the system. Do I need to drain the water heater? The answer is obvious. Yes, and this may be necessary both to prevent breakdowns and to repair the water supply system.

In addition, it is very useful to drain water from the boiler at least once a year. In this way, you will reduce the amount of scale on the tubular electric heaters, and remove large particles from the system that can enter the tank during use.

You can find out the price and buy heating equipment and related products from us. Write, call and come to one of the stores in your city. Delivery across all territory of the Russian Federation and the CIS countries.

Before draining the water from the water heater, take a look at how many pipes are connected to it, as there are models with different numbers - 2 and 3. The liquid is drained in more than one way. A lot depends on which model you have. In the article, we will analyze in detail how to drain water from boilers of well-known manufacturers. However, everything is in order ...

Installed floor boiler

Boiler equipment and liquid drain

Before you properly drain the water from the water heater, you need to deal with its equipment. The storage water heater includes:

enameled tank (there are also made of stainless steel);
internal tubes;
tubular electric heater with;
automatic air vent.

Boiler structure

As a rule, tanks of such equipment are designed for a certain pressure. About 7-10 bar. It turns out that the heater device is a special container operating under pressure. And if there is still water there, then draining it just like that, just by opening the valve, will not work. Since without air supply, only part of the water will flow out of the structure. The liquid that is near the DHW pipe will leave.

And now about how to drain the water from the storage water heater. This can only be done by supplying air to the system. This process is carried out through hot water supply. Let's go through the steps:

It is necessary to shut off the cold water to the water heater.
Open the DHW circuit (for example, a faucet in the kitchen) and slowly release the pressure.
Take a small Phillips screwdriver and twist the flag attached to the cold fluid relief valve. The valve itself supplies water to the equipment.
After twisting, you need to raise the flag and at the same time prepare a niche where water will collect. The container must be placed under. It happens that during professional installation there is already a tube under the spout. It must be connected to the sewer.
If everything is fine, then atmospheric pressure should be enough for the water to circulate due to air suction through the DHW pipe. You can hear the movement of bubbles inside the circuit with warm liquid. Here the system is already prepared, it is necessary to drain gradually, change the container under the water heater (it is allowed to open and close the safety flag). However, atmospheric pressure often fails.
Disassembly may be required. It is necessary to do the processing of the nearest connecting part from hot water to the water heater. It's good when the disassembled connection does not come out of the equipment.
If the model does not imply disassembly, then a rubber hose of a suitable diameter is taken, put on the tap, which is closest to the boiler. It is necessary to blow into the hose so that the remaining liquid pours into the water heater. You can take both the pump and the compressor, but here it is already more complicated.

A good option is to immediately install a boiler with easily detachable connections. Pretty handy in country conditions. Smart users pre-install water drain tee for water heater.

Scheme for placing valves for draining water from the boiler

The boiler has a tube with cold water, which is not at the very bottom. Therefore, when bleeding, a certain part of the water may remain. It is better to take note of this if you have to leave equipment unattended in a cold room for the winter.

How to drain the water from the water heater in the country completely? This is done only by unscrewing the heating element. Anything that is not removed through the tube will go through the installation hole.

How to drain water from a Termex boiler

Termex is a popular manufacturer of water heaters for the home. The devices of the company have established themselves as high-quality and reliable. Before draining water from the Thermex boiler, you should familiarize yourself with the design features and manufacturing nuances. The main devices for draining the liquid will be a rubber hose and a gas adjustable wrench. The process of draining water from the Termex boiler looks like this:

The key covers the pipe through which cold liquid circulates into the water heater.
The hot liquid is then opened on the mixer to create a vacuum.
You need to wait a bit until all the water comes out. This will take about 1-2 minutes.
After the liquid is completely drained, the water heater arrow will be at zero, and the tap will need to be closed.
It is required to slowly unscrew the nuts with an adjustable wrench, in the place where cold water is introduced. When unscrewing, the liquid will not bake again.
Now you need a rubber hose. It is connected at one end to the cold water circuit to the water heater, and at the other end it is sent to the sewer or a prepared container. It is required to disconnect the output of hot liquid from the heater. Fluid should now flow through the hose.
Now finally unscrew the nut fixing the hot water outlet. Air will begin to pass into the system, and the hot liquid will merge completely.

Did the water start draining right away? Blow into the hose. After draining the water, you only need to tighten the nuts back and that's it. The disadvantage of this method is only in the maximum volume of liquid that can be drained, this is 2 liters.

Watch a video on how to drain water from a Termex water heater.

How to drain water from an Ariston water heater

Another popular brand is Ariston boilers. Why focus on the products of this manufacturer? Because here the water is already drained by a more complex method. As a rule, certain tools are prepared: a wrench or adjustable 32 and 24 mm, a straight screwdriver and a 4 mm hexagon.

And now let's move on to how to drain the water from the Ariston boiler:

Close the water supply valve to the boiler.
Open the DHW circuit on the mixer. This is required to relieve pressure inside the tank.
Open the cock on the hot water connection pipe to the water heater so that air can enter the tank.
Open the valve for draining liquid from the boiler. Until then, disconnect the drain hose.
After you have figured out how to drain the water from the Ariston boiler, check if all the liquid has been completely removed.

Do everything in stages, and you will definitely do everything correctly and efficiently, and the equipment will serve you for many years.

Drain from boiler Atlantic

It is right that you are thinking about how to quickly drain the water from the Atlantic water heater and are looking for recommendations if you have equipment from this company. After all, working with these models is not ordinary. Let's go through it step by step:

First you need to turn off the boiler and wait until the liquid cools down. This is necessary for your safety.
The next item is to close the valve responsible for supplying cold liquid to the equipment itself.
It is required to open the warm water valve and turn the lever to the desired position. The goal is to relieve pressure through air supply.
Now close the DHW valve located on the pipe. This will allow air to enter the water heater.
It is necessary to open the drain valve, which is already located on the pipe with cold liquid. Put the drainage type of hose into the water heater and drain the entire liquid from the structure.
Check work. There should be no liquid left. This is important for a summer cottage or equipment located in a country house. Otherwise, there is a risk of breakage or short circuit.

We drain the water from the Gorenje boiler

Do you have equipment from the leading European manufacturer Gorenje? Excellent. Draining water for this brand is even easier. See for yourself by reading how the process goes, and slowly, step by step, do the work.

How to completely drain water from a Gorenje water heater:

You need to disconnect the boiler from electricity. Open the DHW valve.
Wait for the hot liquid to flow completely and connect the hose to the cold water faucet. Lead the other end to the sewer drain, or simply substitute a bucket.
It is necessary to open the drain and again reduce the pressure due to air. All water must flow out. The process won't take long. Maximum 10 minutes.

Take note before draining the Gorenje boiler that the process can sometimes be simplified by using a safety valve.

After all of the above, the question of whether it is necessary to drain the water from the water heater should not be.

Also consider the following cases:

When the water heater itself is turned off before the arrival of winter, it is not recommended to drain all the water from the tank. If the heater itself is not afraid of cold weather, then it is better to leave some water inside. So you protect the structure from the corrosion process. Also, the liquid will come in handy if someone wants to turn on the equipment in the power grid. Because an empty tank heats up quickly, which can cause a fire.
If the device has been turned off for a certain time, and the water in it has stagnated a little, then experts also do not advise completely draining it. Stagnation is best updated by adding up to a full tank. The water heater should be maintained every three months, driving at least 80 liters through the structure.
If the warranty still applies to the equipment, then it is not recommended to repair anything on your own, even small parts. So you just lose the warranty. If you have problems with the water-heating structure, be sure to wait for the masters who will drain the liquid for you and fix the breakdowns. After all, it's free under warranty.

Now you know how to remove the boiler and drain the water from the electric water heater. Remember that any brand of equipment implies similar draining actions, such as disconnecting from the network before starting work, shutting off the water supply, and so on, however, some brands have their own nuances that should be considered.

At the end, I would like to give advice. When disassembling and assembling the water heater, be extremely careful not to damage the rubber gaskets or plastic parts. Otherwise, you risk compromising the integrity of the structure, and the boiler will leak, while the search for new rubber gaskets will take a lot of time.

Sometimes you have to leave the house unattended, if this time falls in the winter, when the water in the pipes can freeze, there is a danger of equipment failure. In this case, as well as in cases of repair of the waterfall system, it may be necessary to drain the water from the boiler.

In addition to the cases described above, useful to empty at least 1-2 times a year, this will reduce the amount of scale on the heaters, as well as save the system from large particles that could get into the tank during operation.

In order to drain the water, first look at how many pipes are leading to it. Due to the difference in models, there may be 2 or 3. There are several ways to drain water. It all depends on what model you have.

How to drain water from a boiler

Consider the procedure for draining water for the most popular water heaters.

Boilers "Termex"

The main tools for draining are a rubber hose and a gas adjustable wrench.

With a key close the pipe through which cold water enters the boiler.
Thereafter open the hot water faucet on the mixer so that no vacuum is created.
Wait a bit until the water drains. This will happen in about 1-2 minutes.
After the water has drained completely and the boiler needle is at zero, turn off the faucet.
Carefully unscrew the nuts adjustable wrench, in the place where cold water is introduced. When unscrewed, the water will not flow again.
Further take a rubber hose, connect it with one end to the cold water supply to the boiler, and direct the other end into the sewer or prepared container. Disable hot water output from the boiler. At this point, water will begin to flow through the hose.
After that, finally unscrew the fixing nut for the hot water outlet. At the same time, air will begin to be recruited into the system, and hot water will merge completely.

If at this moment the water does not start to drain, try blowing into the hose.

After merging, you just have to tighten the nuts back and that's it. The only disadvantage of this method is that the maximum amount of water that can be drained is 2 liters.

This material will help to repair the Termex water heater:

Video illustrating the process of draining water from the Termex boiler:

Water heaters "Ariston"

It will be a little more difficult to drain water from this model. To begin with, you need to have tools such as: a 32 and 24 mm spanner or adjustable wrench, a straight screwdriver and a 4 mm hex key.

Close the water supply valve to the water heater
Open the hot water tap on the mixer, this is necessary to relieve pressure inside the tank;
Open the tap on the hot water connection pipe to the boiler so that air can enter the tank;
Open the tap for draining water from the water heater, after connecting the drain hose;
After draining, check if all liquid has been removed.

Boiler cleaning

In order for your boiler to serve you for more than one year, need to be cleaned regularly. Best of all 2 times a year, but this is not necessary, in most cases one time is enough. It all depends on how often you use it and how clean your water is. If this procedure is not carried out at all, then corrosion, oxidation of metals may begin, as a result of which scale is formed. In order to minimize the number of breakdowns, when choosing a water heater, ask the sellers about which thermostat is in the boiler.

It is better not to buy water heaters with thermostats made of ferrous or galvanized metals, they do not clean rust well and do not process water well. The best options are models with magnetic thermostats. With a strong scale, on the thermostat (heater), it is necessary to replace it with a new one. Cleaning the old one is a waste of time and effort. Even if you clean it, it will get dirty much faster the second time.

So, let's start cleaning:

The cleansing process ends here.

Although the boiler does not require much attention, but for its good work and long service life, at least once a year, give it a little time. After all, it is much cheaper to replace some parts in it than to buy a new one later.

Doubt does the boiler need cleaning? Just watch this video:

Strong advice. When disassembling and assembling the boiler, try not to damage any rubber gaskets or plastic parts, be as careful as possible. Otherwise, the boiler may leak, and the search for new gaskets will take a lot of time.

The boiler belongs to simple household appliances and in order to understand how to drain water from a water heater, it is enough to understand its device.

The basis is a capacitance with input and output. A safety valve for pressure relief is placed at the inlet. The same valve prevents the liquid from flowing back into the water supply network.

Each such device has detailed instructions for use. It is in it that the manufacturer indicates how to drain the water from the boiler.

Drain from the boiler Ariston

In case of termination of operation of the Ariston device for a long time, it is necessary to completely empty it. To do this, unscrew the plug with a key. It is located at the top of the mixer.

For work you will need tools:

wrench;
straight screwdriver;
hexagon (4 mm).

How to drain water from an Ariston water heater (step by step):

Disconnect from network.
Close the taps of the mixer and water supply.
Unscrew the hose from the shower and the safety valve from the outlet pipe.
Unscrew the hose that supplies water. Water should flow out of the inlet water.
Unscrew the plastic nuts of the pipes (inlet and outlet).
Remove the faucet cap, unscrew the screw, remove the faucet handle and gaskets around it.
Do not completely remove the water heater housing from the tank.
Unscrew the metal plug of the top of the mixer with a hexagon.
Drain the water from the hole that was closed by the plug.

When draining, it is better to keep the tank upright. The mixer tap must be open. The draining procedure will take approximately 20 minutes.

Drain from the Termex boiler

Termex storage water heaters can be round and flat in shape. The number of pipes connected to it depends on this.

The flat view works with two pipes: cold water supply and hot water intake. Often they are equipped with a third nozzle with a plug. It should be unscrewed, hook the hose, then unscrew the nut of the hot water pipe and drain it.

Tools required for work:

wrench;
rubber hose.

How to drain water from the boiler (algorithm of actions):

Disconnect from network.
Shut off the running water supply.
Open a hot tap.
Wait until the liquid drains.
Close the hot water tap.
Unscrew the nuts of the flowing water inlet with an adjustable wrench.
Twist the check valve, prepare a hose to drain the contents.
Unscrew the nut from the hot water pipe so that air enters the system, water goes into the hose.

Drain from the water heater Electrolux

Drainage of water from the unit is carried out using a safety valve.

Before starting work, make sure that it is disconnected from the mains, the cold water supply valve is closed and the hot water tap is open.

For most storage boilers, the algorithm of actions is similar to how to drain water from a Thermax and Electrolux water heater.

Removing residual liquid from the water heater tank

After draining by the described methods, the container still does not empty to the end, liquid remains in it. Its amount directly depends on the model of the water heater and the layer of sediment formed.

To completely remove it, you will need to remove the heating element. In this case, it is better to move the container to the floor.

Work algorithm:

Remove cover.
Disconnect electrical components.
The boiler will need to be raised in a vertical position, substitute a container for a dirty solution with garbage on it.
Unscrew the heating element nut and clean the boiler cavity from formations and liquid.

In what cases is it necessary to drain the water

The most common question, whether it is necessary to drain the water from the water heater, there is no clear answer.

There are several reasons why you cannot do without draining the liquid from the water heater. This is required in the following situations:

When the water heater is located in an unheated room, where the temperature does not rise above +5°C. If this is not done, the water in the container will turn into ice. This can permanently ruin the device, and even the service center specialists will not be able to fix it.
When carrying out repair work and replacing the magnesium anode. It is worth emptying the unit yourself only after the end of the warranty period.
If necessary, get rid of sediment and scale, which slow down the process of heating water. Such cleaning should be carried out every 2-4 years of operation of the device. The speed of clogging directly depends on the quality of cold water.

Attention: Do not drain water unless absolutely necessary. Many users make such a gross exploitation mistake.

the device will not be used for a certain time, while the temperature in the room where it is located will not fall below the permissible level;
the defective instrument is still under warranty.

The internal elements of the water heater corrode much faster when in a dry and empty tank. This increases the likelihood of damage to the heating element by accidental switching on of the boiler. It may even cause a fire.

Many people drain the water out of fear of a musty smell, but you can get rid of it by passing it through the device several times. You can also warm up the liquid in it well, and then drain it.

In case of any malfunction, it is better to contact specialists who know how to drain water from the boiler without harm to it. Then the warranty for the purchased device will be preserved. In case of self-draining, the service center has the right to refuse warranty service.

If running water enters the apartment or house, which meets all indicators for softness, you should not open the water heater for cleaning. The less interventions in the technique, the longer it will last.

The role of the magnesium anode in the storage tank

One of the main parts of an electric tank is a magnesium anode. This is a metal pin, on which a layer of magnesium alloy (up to 15 mm) is applied. It is designed to protect the inside of the device from corrosion. It is because of it that the tightness of the boiler can be broken, and it will begin to leak. In this case, it will have to be replaced with a new one.

The anode begins to break down when the water is filled. That is why, many empty the electric heater in an effort to extend the life of the magnesium layer. Especially if the water heater is used only a few months a year. However, they forget that corrosion also occurs in a dry container that has not been dried properly.

Different manufacturers suggest changing the part once a year. But some produce units in which the anode functions throughout its entire service life. It all depends on the brand of product and the hardness of the incoming water.

How to drain water from a water heater: Ariston, Termex, Electrolux and not spoil

The boiler belongs to simple household appliances and in order to understand how to drain water from a water heater, it is enough to understand its device. From the article you can find out a more detailed algorithm of actions for the three most popular brands

How and why to drain the water from the water heater?

If a storage-type water heater is installed in your apartment or summer cottage, then it requires periodically, and sometimes suddenly, to completely drain the water from the containers of the device.

Even if equipment manufacturers claim that this process is as simple as possible, in reality everything is not so simple.

If you follow the instructions of the device, then you just need to unscrew a few taps or valves, and this will solve all problems. But usually in such cases there is a need to remove the heating element.

When may it be necessary to drain the water and when it should not be done?

During the operation of the storage water heater, various situations may arise, after which it is necessary to drain the water:

The liquid must be drained if the device was installed in unheated rooms where the air temperature is less than +5 degrees.

If the water is not drained, it will freeze. In the event of freezing, it will no longer be possible to do without service maintenance of the heating device, or the device may fail and you will have to purchase a new water heater.

Servicing or any repair work on the heater also requires draining the water, for example when replacing the magnesium anode.

Repair and service maintenance of water heating equipment is almost impossible to perform if the tank of the device is filled with water. You should be aware that it is only possible to repair or service the device on your own after the full expiration of the warranty period for your heater.

If it is necessary to clean the tank from scale, or sediment, which sooner or later will necessarily form on the walls of the tank.

This event is recommended by various manufacturers of water heating equipment to be held once every four years. Naturally, this depends on the quality of the water in your tap.

But, many of the users of such equipment still make mistakes by draining water without extreme necessity.

If the device is not used for a sufficient time, and the temperature in the room or environment does not drop below that recommended by the tank manufacturer.

Various elements of water heaters can be subject to corrosion and all kinds of damage if there is no water in the tank. In addition, you can accidentally start the device without water. In this case, there is a risk of failure of the heating element or even a fire.

Naturally, if the water is in the container for a sufficiently long time, then it will deteriorate over time, acquire a smell and become musty.

To avoid this, it is necessary to update the volume of water in the tank a couple of times, and then warm up the equipment well.

If the device is defective, or it is still under warranty, then you should not drain the water from such a device.

At best, you will violate the terms of the warranty, and the service providers will refuse to service your device.

If the device suddenly fails, you should immediately call a service specialist or manufacturer's representative who repairs this equipment. The service specialist will be able to drain the water himself, if necessary, and this will not violate any warranty obligations.

Water heating equipment, like many other devices, does not like interference with its internal parts. If sufficiently soft and high-quality water flows in your pipes, then you should not open the device without special need.

Thermex water heaters

In order to drain the water from the tank of the Thermex water heater, you must first disconnect the device from electricity.
Then you need to turn off the cold water supply. This can be done by turning off the valve.
Attention! Be sure to wait for the hot water to cool down or you can use it to good use.
It is necessary to relieve the pressure in the container of the device. This can be done by turning on the hot water, then waiting for a while until the water runs out, then turning off the faucet.
Next, you need to unscrew the nuts at the bottom of the safety valve for the water heater in the place where cold water is connected to the valve.
Now you can twist the valve. To do this, you may need a hose to drain water into the sewer. Immediately, when the valve is unscrewed, a hose must be connected, otherwise water will flow to the floor.
So you got to the hot water pipe. From it you need to twist the nut. Then water will flow through the hose, because air enters the heater.

How to drain water from an Ariston water heater?

In order to drain the water from the tank of this water heater, you need to do the first three steps. They are the same as for devices from Termex.

It is necessary to open the valve located on the water pipe for hot water. This will allow air to enter the tank.
Next, you need to connect a hose to the cold water pipe. The hose must be lowered into the sewer.
For example, you can lower the hose into the bath. The hose must be securely fixed so that it does not jump out of there and douse you and the entire room with water.
Now you need to open the drain valve, which is usually located on the pipe, and you can start draining the water.

If it is necessary to transfer the water heater to another place, it is worth using metal-plastic pipes for water supply, this option will be the most economical.

If you prefer a more reliable option, then choose polypropylene pipes.

Removal of residues

If you have successfully used the methods to drain the water, and all the water has already drained, do not rush. There is still liquid in the container. The volume of liquid remaining in the reservoir varies from manufacturer to manufacturer and differs depending on the models. Also, the amount of water remaining may depend on the amount of sediment that accumulates during operation of the device.

To make the tank completely empty, you have to remove the heating element. In order to perform this operation, it may be necessary to remove the tank and place it on the floor to facilitate the removal of the lower casing.

Now that the tank is on the floor, you can begin to remove the casing. To do this, carefully disconnect all electrical elements of your device;
At this step, it will be more convenient if the device is hung back where it was. It is better to install a bucket or other suitable container under the tank so that dirty liquid and debris are drained there, which will surely fall out of the tank tank;
Then you need to unscrew the nut of the heating element. This takes a lot of effort, but don't overdo it. After this step, the remaining water, scale, and various formations will drain from the resulting hole into the bucket.

Approaching the final part of the work, it must be said that, without any particular reason, it is not worth draining water from the reservoir of water heating devices. However, if you really want to, then you need to follow these instructions as clearly as possible.

When draining, water can pour onto the floor, so you need to first acquire rags in order to wipe the water in a timely manner.

If during the installation of the water heater you or the installer of the device did not install tees, you must definitely do it yourself. This will make draining the tank much easier.

How to drain water from a water heater

From storage water heaters that are installed in a residential building or apartment, water should be drained periodically. Sometimes this manipulation may be needed suddenly.

Despite the fact that manufacturers of such systems assure buyers of the simplicity and ease of the procedure, that is, how to drain water from a water heater, not all owners can figure it out.

How can you do it

The design with a valve and a tee is quite rare. But if you have just such a unit, then to drain the water, you must turn off the water at the inlet to the boiler, and then open the tap located between the valve and the inlet pipe.
Devices equipped with a trigger (a lever resembling a trigger) on the safety valve get rid of water easily: just press this lever. At the same time, it is desirable to fix a tube or hose on the nose of the valve, which will drain the flowing liquid to the designated place. True, the process will take at least two hours in duration.
In a heater equipped with a non-return valve, unscrew the cover counterclockwise. In this case, the pressure will depend on the amount of water in the tank, respectively, the more it is, the higher the load. As the volume of the liquid decreases, the pressure will decrease. In advance, you should take care of a long, durable hose and a container where water will be drained. It is optimal to direct the flow directly to the bathtub, sink, toilet bowl or buckets. Sometimes it happens when the check valve is unscrewed, there is water in the tank, but it does not flow out. In this case, check the hot water outlet: if it is completely unscrewed, air will enter the tank.
If desired, the check valve of such a device can be “relocated” to another place - to a cold water meter. True, the employees of Vodokanal strongly disapprove of such manipulations. By installing such a system, the owner will prevent water from flowing from the tank into the pipeline when the supply is turned off, and will also allow it to be stored and filled with other containers (for example, a toilet bowl).

Important: before draining water from the boiler, it is necessary to cool the liquid. When turning on the electrical unit, be sure to make sure that the tank is full, otherwise there is a high risk of not only damaging a very expensive device, but also starting a real fire.

When to drain water

Scale and salt deposits that form in the water heater tank during operation must be removed regularly. These manipulations are periodic in nature and prevent damage to the device, thereby extending its service life. But there are situations when emptying the tank must be carried out "according to emergency indicators":

When the unit is in a room without heating and the ambient temperature may drop below +5 degrees. If the liquid is not drained in time, it will turn into ice. And then you have to contact specialized service centers, or even buy a new device.
If the device does not work or needs repair. True, this issue is best left to warranty service professionals. Independent actions to eliminate the cause of the malfunction are possible only after the expiration of the warranty service agreement, otherwise the owner will lose the opportunity to repair free of charge.
If the water quality leaves much to be desired, it may be necessary to clean the tank from the formed salts and scale more often than the period recommended by experts (1-2 times during 2-4 years of operation).

Unfortunately, some owners of boiler systems make mistakes by emptying the tank of water for no apparent reason.

When not to drain water

The most obvious is when the water heater is under warranty and gives out “flaws”. You do not need to fix water and visible problems with your own hands, call the warranty wizard. Otherwise, experts can quite justifiably refuse free repairs. Therefore, call the professionals.

If the device is supposed not to be used for some time, but the temperature in the room will be above +5 degrees, then even for the winter it is not necessary to drain the water. Boiler elements are faster exposed to external factors (corrosion, dust, etc.) without water than under it. In addition, there is always a risk that the owner will forget about the lack of water and turn on an empty device in the network, this will easily provoke the failure of the heating element.

A long well-deserved "rest" of the unit will inevitably lead to the fact that the water will acquire a characteristic stagnant smell. To get rid of it, you just need to completely change all the liquid (two to three times) and warm up the device thoroughly before starting work.

Without unnecessary necessity, it is not at all worth climbing into the device and operation of the boiler. Each new "intervention" in his life increases the chance of a breakdown.

What to do in case of breakdown

When the water heater behaves strangely, there are interruptions in operation, sudden shutdowns and extraneous sounds, the device definitely needs to be repaired, which means draining the water. But only if it is under warranty, it is better for the owner to call for service, since free help will “burn out” with self-repair. Even during installation, it is desirable to make sure that the seller and the repairman are from the same organization. In this case, it is much easier to get comprehensive qualified support. Warranty repairs in most cases are carried out at the place of installation of the unit.

Instructions on the example of a Thermex water heater

The initial action (always, during any work with electrical appliances) is to turn off the power supply.
After disconnecting the boiler from the mains, turn off the valve that regulates the access of cold water and let the hot water cool to room temperature (or use it up).
To reduce the pressure in the tank, turn on the hot supply on any tap closest to the water heater and leave it on until the water runs out.
In the place where the cold water pipe goes to the boiler, there is a safety valve. Below there are nuts that need to be unscrewed.
After the nuts, unscrew the valve itself, keeping the hose ready, which must be attached to the hole immediately, and the drain container, otherwise some of the moisture from the tank will spill past.
Having completed the manipulations with cold water, proceed in the same way to hot water, unscrewing the valve from the corresponding pipe. The water will flow quickly as the tank will begin to fill with air.

Instructions on the example of an Ariston water heater

The first three steps are performed in the image and likeness of the Termex boiler. The next steps look like this:

on the water supply, turn off the hot water supply valve to fill the tank with air;
on the pipe that brings cold water to the boiler, fix the drain hose, after lowering it into a container or bath (sink, toilet bowl);
unscrew the valve on the same pipe to empty the tank.

finishing touches

Draining the water from the water heater tank is not the end of the work, especially since a fraction of the moisture is still in the appliance tank. The amount of liquid depends on the model/manufacturer of the device and on the amount of scale/deposit.

To completely free the boiler from water, it is necessary to remove the tubular electric heater (TEN). To make the casing easier and more convenient to remove, and there were no problems with the electrical components, the device can be lowered to the floor and then hung back.

Before removing the last remaining moisture, often dirty sediment, place a bucket or basin under the tank. And prepare rags, as such work is often accompanied by accidental smudges. Unscrew the nut on the heating element and drain the water.

Important: if there is no need, the water from the water heater should not be drained. But in the case when the reason is serious, and the warranty has already ended, carefully follow the recommendations to avoid mistakes.

To facilitate subsequent drains, tees can be installed on the boilers.
