Electric heaters and boilers are equally in demand today. How to install such equipment will be described in this article. With the help of such a device you can cope with disconnection problems hot water. Among other things, such installations can operate on an ongoing basis. In a wide range of modern stores you can find storage or instantaneous electric boilers, the latter of which are in less demand, because they are inferior to storage boilers in terms of volume and profitability. To install such a device, you can use the services of specialists or do the work yourself, but you will need to follow all safety regulations. To do this, the electricity is completely turned off and the hot water pipes are shut off.
If you decide to purchase such equipment, you should find out in advance. Of course, doing the work yourself is cheaper. If you refuse the services of professionals, you should prepare a certain set of materials for installation. Will need or safety valve, two flexible water hoses, as well as two dowel nails. At the time of buying water hose It should be taken into account that you will need two elements, the length of each of which is 2 m. However, the length will depend on the distance to the insertion into the water supply system. When purchasing dowel nails, please note that there should be hooks at their ends. By the way, about the safety valve. It is worth mentioning that it comes complete with an electric boiler. The valve should have a diameter of 10 mm.
So, you need a boiler. You should learn how to install such equipment before purchasing it. Do you want to do the installation yourself? Good luck! However, it is worth considering that in some cases, doing the work yourself will void the manufacturer’s warranty. In addition to materials, you should prepare certain tools, including: screwdrivers, drills with a Pobedit tip for fastening to brick wall, adjustable wrench and hammer drill. The latter can be replaced with an electric drill.
Many home craftsmen, having learned how much it costs to install a boiler, prefer to do all the work themselves. This is not surprising, considering that such services cost about 5,000 rubles. Do you have the skills and know which side to approach the hammer drill from and how to hold the screwdriver? Then why overpay? But if you do the installation yourself, you will have to prepare properly. An important role here is played by the reviews of those people who are not new to doing this kind of work. If you study all the recommendations, you can come to the following.
The process should begin by choosing a place for mounting in the bathroom or toilet. Most often, such equipment is installed above the toilet, where it will not disturb anyone. It is necessary to check the strength of the wall, as it will have to bear the load from the boiler. If the room has unreinforced plasterboard partitions, then you should refrain from installing the unit on them. If the boiler volume is 50 liters or more, the wall will bear a double load, that is, 100 kg.
Before installing a boiler in an apartment, you should decide on the lowest point of the equipment location, marking it on the wall surface. Next, the master measures the distance from the mounting strip to the bottom point. The first is firmly welded to the equipment body. The resulting distance must be marked on the wall. The next step is to drill two holes. The craftsmen emphasize that you need to remember that the fastening bar does not have such holes; anchors with a hook at the end must cling to its edge.
So, everything is ready to mount the boiler on the wall. How to install it correctly? The question is not an idle one: the structure must be securely fastened, because the fall of such a massive device can cause injury. If the wall is made of concrete or brick, then the craftsmen recommend using a hammer drill with Pobedit drill. For wooden wall used regular drill on wood, the diameter of which is smaller than that of a plastic dowel. The latter must be installed in the hole and, if necessary, driven in.
The metal anchor is screwed in until it stops turning. As a rule, a depth of 12 cm is sufficient. The boiler should be hung by hooking the anchor hooks onto the bar to secure it to the body of the unit. At this point, the process of hanging the equipment can be considered complete. As you can see, the technology is not very complicated, so anyone can master it House master. At the next stage, you can connect the boiler to the water supply system; for this, flexible hoses should be used.
Judging by the reviews, polypropylene pipes can be used instead of flexible hoses, but this will cost more and take more time. At the bottom of the boiler there are two tubes, one of which has a blue plastic ring. Cold water will be supplied through it. The second tube is indicated in red and is intended for hot water outlet.
According to craftsmen, in the place where the supply takes place cold water, a safety valve should be installed. It is usually included in the kit or purchased additionally. The first step is to attach the safety valve. Don’t forget to first wrap plumbing flax or sealing tape around the threads.
The craftsmen advise that at the next stage, screw one end of the flexible hose onto the safety valve. In this case, you need to stop using tape, since the hose nut has a rubber gasket that acts as a sealant. Well, the question of how to install a boiler in an apartment is almost resolved. The next step is to screw one end of the flexible hose to the pipe from which the hot coolant comes. In this case, sealing tape is also not required.
Now you can start connecting the free ends of the hoses. The end to which cold water will flow should be connected to a water pipe. A valve or tap must first be installed at this location, which will allow, if necessary, to shut off the liquid supply. This recommendation should not be neglected, since the boiler may fail during operation or require replacement of spare parts. The free end of the other hose should be connected to the pipe that goes to the mixer.
In principle, installing a water boiler yourself is not difficult. You just need to arm yourself with certain knowledge (in addition to tools and materials). And there are many nuances in this matter. In particular, before connecting the unit, it is necessary to connect the tees to water pipes. In the absence of certain experience, it is better to entrust this work to professionals. Now you can get busy electrical part. If we are talking about Thermex brand water heaters, then they have one feature, which is the presence of a cable for connection along with a plug included. Moreover, this element is connected to the boiler. If this is not so, then Consumables will have to be purchased separately.
And further. To ensure that everything goes off without a hitch (read: without accidents), craftsmen strongly recommend observing safety precautions when working with electricity.
If you are faced with the question of how to properly install a boiler, then you should know that you do not have to open the lid if everything in the equipment is already connected. It is enough to install a grounded outlet in advance, which should be located close to the equipment. You should turn on the cold water tap to check how tight and reliable connection. If there are no leaks, the boiler plug can be connected to the outlet. Now you know how to install. If you did everything correctly, the indicator on the case should light up. After this, you can set a certain temperature using the regulator, which is usually located at the bottom.
It is important to remember the main mistakes that are made when connecting the equipment described in the article. In particular, before installing a boiler in the bathroom, experts recommend making sure there is a circulation system. This will minimize energy losses if there is always hot water in the pipes.
Since centralized hot water supply to residential buildings is becoming irrelevant, autonomous storage water heaters are coming to replace them. An important advantage of these household appliances is simple installation that does not require special permits. We offer to help you realize this advantage and consider how to properly install and connect a boiler to the water supply of a private house or apartment.
As a rule, storage and instantaneous water heaters are equipped with fastenings - brackets or brackets designed for hanging the unit on the wall. You will have to buy the remaining components and pipeline fittings yourself.
For installation and correct connection electric boiler By standard scheme prepare a set of materials:
Note. Some manufacturers complete their products with safety valves with rubber gaskets.
This is what the pressure release valve from the tank looks like
If the pipe connections to the storage water heater are planned to be built into the wall, it is better to take a metal-plastic pipe, of stainless steel or cross-linked polyethylene. It is not recommended to lay PPR wiring hidden. Do not forget about the brackets for attaching the pipes to the walls - the connections should not load the boiler pipes with their own weight.
The length of the cable for connecting to the electrical network depends on the distance from the main control panel, from where a separate power supply line will have to be installed. The second connection option is to the nearest electrical outlet box. For open method prepare plastic cable ducts or a corrugated sleeve.
When laid hidden, the pipes immediately go into the wall
Boiler connection option indirect heating depends on the type of boiler and heating scheme. But you will definitely need pipes with fittings and a circulation pump low power, developing a pressure of 4 m of water column (0.4 Bar).
Before connecting the water heater to the electrical network and water supply, the unit should be securely mounted on the wall in convenient location. Let's give some recommendations for placing the boiler:
Reference. IN apartment buildings– in new buildings, a separate room is often provided for the placement of water heating equipment.
Having chosen the location and height for hanging the water heater, mark the mounting points on the wall. The task is made easier by the design of a standard bracket in the form of a strip with slots for hooks, welded to the boiler body. Drill holes 12 cm deep, hammer plastic stoppers and screw in hooks with a diameter of 8 mm. The second fastening option is Ø10 mm anchor bolts. Together with an assistant, lift the heavy unit and hang it by the bracket.
Products of some brands are equipped with special paper templates that facilitate the initial marking of attachment points. There are boilers with separate mounting plate, fixed to the wall with several dowels. The housing is screwed to it with ordinary bolts.
Electrical or gas boiler provides for the selection of water for domestic hot water needs from the upper zone of the reservoir, where it reaches maximum temperature. Makeup from the cold water supply is carried out to the lower zone. This leads to the following problems with emptying the tank:
The presented boiler connection diagram solves the listed problems and allows you to empty the tank at any time, spending literally 15 minutes. Each element of the harness clearly performs its function:
To correctly assemble the electrical boiler piping, it is enough to connect the pipes according to the diagram and attach them to the wall with clamps. Lastly, the American ones are screwed on, and a flexible hose is put on the “spout” of the safety valve and directed into the sewer. The installation process of a storage water heater is clearly demonstrated in the video:
After assembly, check the tightness of the joints by opening the cold water supply. Filling the tank is done with the “hot” mixer tap open to release air. After making sure the connections are secure, proceed to electrical installation.
The power of the vast majority of water heaters does not exceed 3.5 kW. If your consumption household appliance is within the specified limits, feel free to connect the boiler through one equipped with a grounding contact (required!). The work is simple: run a three-core cable from the distribution box using a corrugated cable or plastic box, and place a socket next to the heater.
Exposed wiring and outlet knobs are not popular with all homeowners. To make the electrical connection to the water heater more efficient, follow our instructions:
Plug in the boiler filled with water and check its functionality. Since on budget versions of the devices the heating temperature is regulated directly on the heating element, do not rush to put on the lid. Wait until the water reaches comfortable temperature(look at the index) and turn the adjusting lever at the end of the heating element so that the heating element turns off.
The unit is a tank with a built-in coil that heats the main volume of water. Accordingly, the heat exchanger is connected to the boiler, and the tank is connected to the hot water supply system. The same safety valve is used to drain excess water that expands when heated.
The easiest way is to connect an indirect heating boiler to a single-circuit boiler equipped with special pipes. Inside the heat generator there is a three-way switching valve that distributes the flow of coolant for heating or loading the hot water boiler - as you wish the electronic unit management. IN in this case The heater coil is simply connected to the appropriate connections.
Note. It's about about , staffed with its own circulation pump. In floor-standing versions - solid fuel and gas - pumps and three way valves, as a rule, is not provided.
The operation of the pumping unit is controlled by a thermostat built into the boiler (it has a special socket). When water withdrawal begins, the container cools down and the thermoelement starts the pump; when it is heated sufficiently, it stops.
Important point. Connection to a double-circuit boiler is made according to a similar scheme. It is not allowed to “hang” the boiler on the second circuit of the heat generator, operating from a flow-through heat exchanger. How to properly strap in such cases, watch the video from an expert:
You don’t have to read the instructions at all, don’t use any piping fittings, and supply water directly to the electric heater. The unit will function successfully until the first problem or repair of the water supply system, when you have to drain the water from the container. But there is one part that must be installed - a safety check valve. Without it, the expanding water can rupture any weak connections or the tank itself.

How to provide hot water a home in which hot water supply is not provided or is regularly turned off? Using a heater. You can find it on sale convenient devices various designs and productivity.
They are relatively easy to install and manage. The most important stage installation of the device - connecting it to the water supply system of the house. If the connection diagram of the water heater to the water supply is strictly followed, the unit will faithfully serve for many years.
At self-installation With such a complex electrical appliance, a number of important nuances should be taken into account.
Two types of devices are most popular among buyers: storage-type devices, also called boilers, and instantaneous water heaters.
Water boilers: a necessary modern attribute in the bathroom
The first ones function as follows: cold water enters a special tank equipped with a heating element.
There it is heated to required temperature and then served in plumbing system. In a flow-through heater, there is no storage tank; the water is heated as it passes through a special flask in which the heating element is located.
Therefore, the procedure for connecting devices to the water supply system different types varies significantly.
Boilers are easier to install, they are usually cheaper than flow-through heaters and are less demanding on the quality of the electrical network than flow-through devices.
Therefore, storage units are much more popular. Flow-through heaters are installed as close as possible to the point of hot water collection, for example, directly on the water tap.
The device allows you to get hot water almost instantly, but heating costs will be quite high.
Good preparation is the key to successful heater installation. It is recommended that you carefully read the manufacturer's instructions first. Special attention focusing on security issues.
Next important point– choosing a place to install the heater. Here are some useful points:
If the location for the heater is chosen correctly, it will be easier to install and maintain.
The set of tools and materials required to connect the water heater to the water supply system may vary depending on the features of the device.
A novice master can focus on the following approximate list:
You will also need pipes and fittings to connect the heater to the plumbing system. Means of sealing joints are required: flax thread, FUM tape, special paste.
It doesn’t hurt to stock up on a pair of connecting hoses, two or three shut-off valves and the same number of tees in advance.
To connect the boiler to the water supply, you can use special flexible hoses suitable size, but not too long
Only fastening elements are usually supplied with the heater, and they are not always suitable for a particular situation.
For example, if you plan to install the device on a wall with a thick finishing layer, you should stock up with sufficiently long fasteners.
To connect the boiler to the water supply, the diagram shown below is usually used:
The diagram shows the procedure for connecting a storage water heater to a conventional water supply system. The location of taps, shut-off valve, drain, etc. is indicated.
The figure shows the conventional location of the risers, which are designated by the words “cold water” and “hot water”. The numbers “1” and “2” indicate conventional shut-off valves.
One of them is opened so that cold water enters the tank, through the other it is heated to desired temperature the liquid is supplied to the hot part of the water supply.
During periods when the storage water heater is not working, it is recommended to turn off these taps.
Under the numbers “3” and “4” there is another pair of taps. These devices are responsible for the flow of water into the apartment from a common riser.
Usually they are available in every apartment, regardless of whether the apartment has a boiler or not. And if tap “3”, through which cold water flows, is turned off only if it is necessary to stop the water supply to the apartment, then tap “4” should be completely turned off while the heater is operating.
If this is not done, the hot water from the boiler will go into the house riser.
Number “5” is the installation location of the check valve. This is very important element water heater connection systems, since it protects equipment from damage.
If the cold water is turned off (which does not happen as rarely as we would like), it is the check valve that will prevent the liquid from leaving storage tank boiler
If there is no check valve, water will flow out of the device back into the riser. As a result, the heating elements will run idle, which will lead to their rapid breakdown.
It should be remembered that boiler manufacturers usually include a check valve in the delivery package, so it is necessary to check its availability during the process of purchasing the device.
When connecting a storage heater to the water supply system, shut-off valves are used, with which you can control the flow of water into the tank
The tap, which is marked with the number “6”, is designed to drain water from the water heater tank. This tap is used extremely rarely, for example, if the device needs repairs or is to be dismantled.
In this case, according to technology, the water from the tank must be drained. You should not neglect the installation of this element, since emptying a large tank by other means can be quite labor-intensive.
The drain valve must always be located slightly higher than the check valve, otherwise it will not be possible to remove water from the tank.
Thus, if the storage water heater is working, then taps “1”, “2” and “3” should be open, and tap “4” should be closed. If the boiler is turned off, it is necessary to close taps “1” and “2”, and taps “3” and “4” should be opened.
Detailed information about connecting a storage water heater to the water supply is presented in the following video:
In many private houses, and even in large cottages, a storage tank is part of the water supply system.
Sometimes this is the only way to ensure normal water pressure in the pipes in the house. You can also connect a storage water heater to such a system, but a number of nuances should be taken into account: the distance from the tank to the boiler, as well as the pressure in the water supply.
If the space between the water heater and the tank is less than two meters, you can use the following connection diagram to the water supply:
But it also happens that the distance between these devices is more than two meters. In this case, a special safety valve should be installed between the tank and the tap, as shown in the diagram:
If the distance between the tank and the storage water heater exceeds two meters, a safety valve must be included in the connection diagram
If the pressure in the water supply system of the house exceeds 6 bar, experts recommend installing a reducer in front of the water heater, which will reduce the pressure of the water entering the heating tank.
If a diagram of the correct connection of the boiler to the water supply has been drawn up, it’s time to start implementing it. In this matter, much depends on what pipes were used to create the water supply system.
In houses old building can often be found steel pipes, although they are often replaced by more fashionable polypropylene or metal-plastic. When installing a boiler, you should take into account the peculiarities of working with pipes of various types.
There are no special requirements for the material of structures connecting the boiler and water supply system. They can even be connected with a fairly strong hose suitable diameter and length.
Regardless of the type of pipes, before starting any work on connecting equipment to the water supply, be sure to turn off the water supply in the risers.
You don't have to use it for this. welding machine, since the connection can be made using special tees, the so-called “vampires”.
The design of such a tee resembles a regular tightening clamp, on the sides of which there are branch pipes. Their ends are already threaded.
To install a vampire tee, first install it in a suitable location and tighten it with screws.
Between the metal part of the tee and the pipe, place the gasket that comes with the device. It is important that the gaps in the gasket and the tee intended for mounting the hole match exactly.
Then you need to use a metal drill to make a hole in the pipe through a special gap in the pipe and rubber gasket. After this, a pipe or hose is screwed onto the opening of the pipe, with the help of which water will be supplied to the heater.
To connect a storage water heater to a steel water supply, use a metal coupling with special pipes equipped with threads onto which you can screw a stopcock, hose or piece of pipe
The most important point when connecting a water heater is to seal all connections. To seal the thread, use FUM tape, linen thread or another similar sealant. There should be enough such material, but not too much.
It is believed that if the seal protrudes slightly from under the thread, this will provide a sufficiently tight connection.
If the boiler is supposed to be connected to a polypropylene water supply, you should immediately stock up on stopcocks, tees and couplings designed for them.
In addition, you will need special equipment: a device for cutting such pipes, as well as a device for soldering them.
To connect a boiler to a polypropylene water supply, the following procedure is usually followed:
If the water pipes are hidden in the wall, you will have to dismantle the finish to gain free access to them.
It happens that access to pipes laid in grooves is still significantly limited. In this case, you can use a special split-type repair coupling.
The polypropylene side of such a device is soldered onto a tee, and the threaded part is connected to the water supply. After this, the removable part of the coupling is removed from the structure.
To connect a water supply from PVC pipes to a storage water heater, you can use a special adapter, part of which is soldered to the pipe, and a hose can be screwed onto the other part
Working with metal-plastic pipes is not as difficult as working with products made of polypropylene. Such pipes are very rarely laid in grooves, but are connected with very convenient fittings.
To connect the boiler to such a water supply, you can use the following procedure:
After this, all connections should be checked for leaks. To do this, water is supplied to the system and observed to see if a leak appears.
If the connection is not tight enough, the gap must be sealed or the work must be done again.
Unlike storage boiler An instantaneous water heater is designed to heat a flow of water, and not its static volume.
Therefore, instantaneous heaters are usually smaller in size, and it is much easier to incorporate them into the plumbing system.
A flow-through heater is usually placed closer to the place where hot water is used, so that it does not have time to cool down while passing through the pipes.
The easiest way to install such a device is on a faucet that has a shower outlet. To do this, remove the shower head and connect the heater hose to the freed part of the mixer, through which cold water should flow.
Now, instead of a shower in the bathroom, there is an additional source of hot water, which can be connected if necessary. The device is easy to dismantle and install again if the need arises.
But this is not always convenient, because using a shower with this installation method is somewhat difficult.
The figure shows options for connecting a flow-through heater to a water supply. You can use the heater in the kitchen or bathroom for showering
Another opportunity to include a flow-through heater into the system is through an outlet designed for a washing machine.
First, a tee is placed on the pipe, which is sealed using FUM tape or flax.
Then install a tap that will allow you to open/close the water flowing to the heater, as well as regulate its flow.
Since with this connection method the tap will have to be used frequently, it is important to place it in a convenient place. After this, the structure is brought from the tap to the flow-through heater.
The most convenient way to do this is with a flexible hose, which is recommended to be secured with special brackets. But you can also use pipes: metal, polypropylene, metal-plastic, etc.
A water heater has long ceased to be considered a luxury item. Currently, such equipment is installed in almost every home. The most popular are flow-through and storage electric heaters water. We offer you an overview of the main advantages and disadvantages of the mentioned equipment, as well as instructions for its use. self-installation and correct use.
Instantaneous water heaters are best suited for houses and apartments equipped with electric stoves. In this case, the meter and electrical wiring will already comply with regulatory requirements.
The only significant drawback of storage water heaters is their impressive dimensions. However, today manufacturing companies offer their consumers big choice space-saving heater models. For example, if you wish, you can purchase a flat unit.
Installation process instantaneous water heater does not require the performer to have any serious skills. There are two options for installing such a unit: for temporary use and for permanent operation.
This option is usually used when it is necessary to obtain heated water without the possibility of connecting to central water supply. Once this option becomes available, the water heater can be easily turned off or even dismantled until the next use - it doesn’t take much time.
The most convenient for temporary use are models that are initially equipped with a mixer and shower head.
First step. Secure the heater in a convenient place with dowels and screws.
Second step.
Remove the shower head from the home shower hose and connect the hose to the water heater inlet.
Third step.
This option is used in situations where the heater is planned to be used regularly. In this case, the unit is connected to the water supply system.
The connection is made according to the scheme already discussed, however, the supply and output of liquid are arranged permanently. For this connection, special tees and shut-off valves are used.
As a result, heated water will come out of the mixer.
After installing the heater, make sure that all connections are tight and only then accept the device for permanent use.
It is important to understand not only the procedure for connecting an instantaneous water heater, but also the features of its use.
The main rule: a flow-through water heater can only be turned on after the heater coil is completely filled with water.
If the heater coil is not sufficiently covered with liquid, it will break and it will become impossible to use the device.
Regardless of the option you choose for connecting a flow-through heater, use of such a device is performed in the following order:
Turning off the device is carried out in a similar manner - you turn off the heater, wait until cold liquid starts flowing from the shower head, and only then turn off the water supply.
In the case of storage heaters, temporary installation is not provided. You can of course connect to the output warm water an ordinary hose with a watering can, but using such a unit will be absolutely inconvenient.
First step. Select a suitable location to install the water heater and check the wall.
Flow models are quite light in weight. Cumulative ones will put a much more significant load on the wall. Therefore, when choosing a place to install the heater, you need to pay attention not only to the ease of pipe installation, but also to the strength of the surface.
As a rule, heaters with a volume of up to 200 liters are attached to the wall. Tanks of larger volume require exclusively floor installation. If the heater has a volume of more than 50 liters, it is recommended to attach it exclusively to a load-bearing wall.
Second step.
Prepare all the necessary equipment for installing the water heater.
If the required wiring is available with pre-mounted tees and shut-off valves, the installation of the storage heater is carried out in an extremely simple sequence.
First step. Step back approximately 150-200 mm from the ceiling surface and leave marks on the wall for future holes. Thanks to this gap, you can conveniently lift the water heater for hanging and removing the tank.
Second step.
Armed with a drill (hammer) with a suitable drill bit, make holes in the wall with a depth corresponding to the length of the mounting hooks.
Third step.
Hammer the dowels into the prepared holes, and then screw the screws into them. Be sure to leave a gap to accommodate the water heater mounting strip.
Fourth step. Install the tank onto the mountings.
Fifth step.
Install a safety valve at the cold fluid inlet. With its help, excessive pressure will be removed from the system. Connect the tube for draining excess liquid to the sewer pipe. This tube can also be carefully inserted into the toilet tank.
Sixth step.
Connect the cold water pipe to the water heater inlet. The entrance is marked blue. Connection must be made exclusively through the safety valve. At the outlet (marked in red) connect the pipe for discharging the finished hot liquid.
