Water heaters are a necessary household appliance that helps to significantly ease life. We propose to consider how the water heater is properly connected to the power grid, to the water supply, in the country, as well as the installation of a horizontal boiler in the country and in the apartment and general scheme Installation.

Detailed Description of Connection and Design

This way you can connect cumulative water heater ATMOR (ATMOR), Elenberg, Eltron, Etalon, Ferroli, Gorenje, Polaris, Stiebel, Themex, Vega, Termex, Ariston (Ariston), and others. He is considered to be effective option To attach a simple vertical boiler, but first you need to figure out the design of the device.

The standard boiler consists of such parts:

• element heating water - TEN;
• the tank that retains the water temperature on the level;
• thermostat;
• watering systems and water supply systems.

The most important thing when choosing a boiler is a way to attach it to the wall (vertical or horizontal), and the volume of the tank. Most often B. modern apartments Apply vertical devices: they occupy significantly less placeThan horizontal water heaters and are connected to the water supply system much easier and faster.

Step-by-step instruction:

A fuse or a protective valve is a special device that serves to protect the tank from the break at a very high temperature or pressure. This may occur if the fluid pressure in the tank exceeds the nominal indicator (the standard value is 0.6 MPa). The pressure valve hole must be open, because often home experts simply forget in time to ensure that there is an extra hot water into the sewer, which is exposed to their seven serious danger.

It must be said that the standard valve in a set with a water heater most often simply does not cope with its task, and we recommend immediately buying a protective device separately, already providing the needs and capabilities of the boiler.

1. The valve consists of a whole system of parts, including a plumbing tee, directly valve, American coupling, valve reverse action (which protects from mixing hot and cold water, and therefore saves electricity and reduces the pressure on the inner tank of the boiler);
2. Now with pipes and compression hoses, we assign water into the sewer. If necessary, you can use simple garden hoses, although they are not intended for operation in hot water conditions;
3. Seal the connection with the help of a special sealant, we leave it for 4-8 hours to dry out. Water turn off long before the start of the process, even a slightly wet pipe will not be sealed and quickly "will disappear";
4. Next, continue to attach the boiler to the water supply system.
5. We advise you to prefer polypropylene material pipes, they have a much longer service life and are more easily mounted than metallic. They connect them by welding polypropylene, leave a little dried. Some masters spend this operation, having only metal-plastic pipes, but they are much more difficult in the installation less reliable;
6. After with the help of a ball crane, we bring cold water to our boiler, connect, check and, if necessary, fix the place of connection of the water supply hose and the opening of the receipt;
7. Through the same ball crane We assign I. hot water, it provides for the connection of the accumulative water heater, and flowing;
8. It is necessary to make the system in such a way that with closed cranes the water does not flow, but if you close the valve, it was possible to use liquid;
9. Now depending on the connection electric water heater Or the gas water heater we produce, you need to connect the device with the power system, and check it out. When using the first method, all PUE requirements are taken into account: moisture-proof outlets (especially in the bathroom), the grounding of the household appliance is likely to also need a separate RCD for a two-phase boiler, etc.;
10. Check the cable condition, it must be moisture-resistant, durable and elastic.

Install the floor boiler

Installation of an outdoor or horizontal boiler does not take much time, but this is a very surround job. They are often more than 50 kW with power, and they weigh about a hundred kilograms, so they are difficult to transport or simply move on their own. The system is connected to hot and cold water in the same way as the vertical water heater only with the difference that the drain hole is located on top.

Video: Water heater mounting

The grounding system is also more serious, a separate conclusion is envisaged for powerful boilers. It can be easily made with your own hands, just branched the wire from the iron part, and connect it with an independent output to the ground.

This device is mainly used in production, because He has a fairly large volume, and the price is high - from 80,000 rubles (the cost was taken into account by the regions of Ekaterinburg and Moscow).

As you can see, the connection of the flow water heater is a simple task that requires maximum concentration of attention. If it is incorrect to attach a coupling or weakly tighten it, then the breakdown is inevitable, due to this, the service life can also significantly decrease.

No special documents are needed if you buy a water heater, and not a gas column.

The lack of centralized hot water supply or its constant shutdowns force the owners of cottages and apartments to establish water heaters at home. Often it is electric or gas equipment Boiler (accumulative) type. At the same time, in both cases, the scheme and technology of connecting the boiler to the water supply is identical. Connect the heater of water will have to one and the same tap pipes.

Household water heaters (water heaters) are divided into flow and accumulative models. The first are compact and usually installed under the sink in the kitchen or in the bathroom. On the one hand, the hose from the crane of the cold water supply is connected to them, and on the other, the removal to the mixer is either a shower. You can connect such a technique to the water as easy as you connect the airbone or shower cabin. We just need to tighten a couple of nuts on the pipes, without forgetting about Fuma Rent.

Cumulative Water Heater Connection Scheme

With boilers (accumulative analogue) everything is somewhat more complicated. Connection diagram here is a bit different. This equipment is a water-filled boiler in which the heating of the fluid occurs due to the operation of the gas burner or the Tan. At first, such a column is filled from the HPW pipeline, and then as heating and necessity heated to 40-750 with "boiling water" into the DHW pipe.

Types of boilers and water heaters

The accumulative water heater is established in apartments and private houses:

• in the kitchen over or under the sink;
• in the bathroom (toilet);
• in the utility room.

But the closer to it to stand to the riser of cold water supply, the easier it will be to connect the boiler to the HPW. Less distance from the column to the water pipeline - less pipes will have to be laid. The main thing is that the wall in plans to fix the water heating technique turned out to be able to withstand its weight.

Boyler accommodation options in the house

Connect to water pipe

To connect the water heater to the HPW and DHW, will be required:

• wrench (better take a pair of divorce);
• FUM tape;
• tees for cutting in existing pipelines;
• two shut-off valves;
• safety and check valve;
• plastic pipes or hoses in a metal braid;
• truboresis and soldering iron for plastic or appropriate fittings;

The process of connecting a boiler to water supply systems is reduced to connecting two pipes (input from cold and release with hot water) To threaded pipes on the heater housing. And the main point here is the correct cutting of tees under these taps into the existing water supply pipeline.

The order of connecting the boiler to hot water consumers

Bulb in a pipe from metalplastic

If the water supply is made of metal-plastic pipes, then compression or pressure press fittings will be required. With the first when the water heater is connected, it is easier to work, you need to tighten the nuts with the keys. And the second are more reliable, but form a detailed connection.

To mount the tee, you will need to cut a part of the corresponding size on the pipeline. To do this, it is better to use the pipe cutter, but you can take a hand-hack for metal with small teeth. It is only necessary to monitor that the aluminum layer of metal plastic then did not perform on a cut edge. Foil can tighten the pipe inside the pipe, because of which the latter will be ejected.

Boyler connection diagram and consumables

Polypropylene

If you need to connect a boiler to the water pipe made from polypropylene pipes, I will need a soldering iron. The incision is made in the same way as in the case of metal-plastic. Then the tee is heated on the one hand and solder to the pipe, and then soldering the second end of its end. Side stays free end with a thread for connecting the removal from the water heater.

Variants of water supply schemes through a boiler

Steel tubes

We will have to tinker with steel pipes. Here it is necessary to either take for a grinder and then cut into the thread for connecting the tee with a radiator or a cluster, or install the invoice of the clamp ("vampire", a tee clip) and drill the pipeline.

The first option of connecting the water heater to the water supply is more complicated in the installation and more reliable in operation, and the second is faster and simple, but not so durable.
But here how to connect the drain of the washing machine to sewage - you can simply hang the drainage hose on the bath, and you can install a tee with side removal. In the second case, reliability will be an order of magnitude higher.

With steel water pipes, everything is largely similar. However, the inserted tee and the invoice of the clamp give approximately the same result. At the same time, if there is no work experience with a grinder, it is better to use the second option.

Steel pipes are not easy to connect, so more often this option is connected to a boiler for industrial needs or intensive use

Installation of safety valve

If you do everything correctly, then on the tap of the boiler under the rh3 it follows the valve to install the following scheme (from above from the heater down):

1. A tee with a crane for a drain during an accident water from the boiler.
2. Safety valve (from steam pressure).
3. Check valve (from water leaving back to the pipeline).
4. Skipping valve (for cutting off the heater from the water supply).

The safety valve usually goes along with the water heater and is needed to prevent the boiler break due to the abrasiveness of steam. And the opposite avoids the drain of water back into the plumbing when it turns out for one reason or another is empty. This ensures the safety of the electrical heating element.

Connecting a boiler through a safety valve

On the discharge under the DHW, there will be a shut-off valve. But you can additionally put a drain crane. Although it does not make much sense. Inside the boiler, the end of the nozzle for the fence of hot water is always above what is designed for the cold. Therefore, with the input of the HPW, in any case, steals more fluid than from the output of the DHW.

Errors when installing the water heater

Among the major mistakes of the wrong installation of the boiler are:

1. Replacing the safety "breakdown" valve to the opposite (from overheating and explosion of the boiler this option will not protect).
2. Insufficient reliability of fasteners (photos with a toilet water heater broken on the network walks quite a few).
3. Installing the locking valve or long hose between the boiler fitting and pressure reset valve.

In the latter case, if you install the valve, in the closed state, it will not miss excess steam to the fuse valve. The explosion with such a connection scheme will be inevitable. And if you insert a hose in front of this valve, then with the increase in pressure, the latter can be broken.

Water heater, he boiler, it is the autonomous heating device in some case is the most good decision Problems of hot water supply. It is used in those houses and apartments, where there are no hot water, where there are, but with interruptions, but most often think about how to connect a boiler to the water pipeline those who want to save.

We present the calculations on the example of Moscow (knowing about the tariffs in its region, you can also calculate economic benefits). On average, a family of 4 people spends 8 cubic meters of hot water per month. The tariff for hot water in 2016 is 108.41 rubles. (population). It turns out, per month at the DHW will have to pay 867.28 rubles.

Now as for the water heater. For a family of 4 people, we take a 100-liter cumulative boiler 2 kW. Up to the required temperature, such a device heats the water on average in 2.5-3 hours, it turns out 6 kW per day, 180 kW per day. At tariff at 3.52 rubles. The final amount of the payment - 633.6 rubles. As you can see, 25% cheaper.

If you take into account the most economical - flowing water heater of 5 kW, the tariff will be 75% cheaper than hot water supply. The average performance is 2 l / min. For heating, 50 liters will be needed 25 minutes (0.42 hours). 0.42 x 5 \u003d 2.1 kW per day. The month turns out 63 kW. In cash equivalent 222 rubles.

Since economic benefits, as they say, there is time to tell how to connect the boiler to the central water supply.

Varieties

To date, the range of water heaters is very extensive. The differences are in the method of heating, power, the form of the tank, the installation method, etc.

Water heating method:

• electric;
• gas;
• combined (gas / electricity);
• indirect heating of water through a boiler.

Water supply method:

• pressure;
• handyless.

Method of installation:

• outdoor version;
• horizontal and vertical suspended.

Form of an external tank:

• round (cylinder);
• oval (rectangle with rounded corners).

Device

• external casing;
• inner tank;
• thermal insulation protection from polyurethane;
• tubular electric heater (TEN);
• thermometer;
• thermostat.

This type of water heater is referred to as accumulative due to the presence of a tank filled with water. Ten heats water to a certain temperature, and thermal insulation between the inner and external casing holds the temperature. As required, water is spent, recruited automatically and again heated.

Device of a flow aggregate

In the flow boiler, due to the work of a more powerful Tan, water, passing through it, warms up instantly. The temperature is regulated by reducing or increasing the stream.

Such devices are mounted directly to the point of the plumbing system, but only one - it is impossible to get hot water from one flow boiler and in the kitchen and in the bathroom at the same time.

The easiest in connection and operation is an electric boiler, because it does not require harmonization, special permission and acquisition of additional tools.

Flowing VN is very powerful household applianceTo connect which you need a wiring 30 A and mandatory grounding. In order to limit damage to the line on flowing water heaters With a power of Tan more than 5 kW in the kit is missing network cord and a full-time plug.

The accumulative WD has a standard power of 2 kW, where the supply current 10 A. The usual "home" wiring is quite enough to work this unit.

Considering the fact that PV does not give the highest possible hot water, it is due to instant warm-up, many stop their choice on cumulative. Moreover, it can be connected to almost everyone.

How to connect correctly

Preparatory actions

1. Preparation of a place at the rate of "walking" accessibility to connecting elements - water supply pipes and a socket.
2. The wall on which the mounted boiler will be mounted should be strong - the total mass of the device in 100 liters will be 130-150 kg depending on the inner structure.

Required tools and materials:

• set of adjustable keys;
• roulette;
• mounting level:
• perforator (for the carrier wall) or drill;
• passatia;
• connecting tees-fittings;
• shut-off cranes (on inlet pipes);
• sealer (panel, paste, ribbon, etc.).

Installation process

Canopy boiler on the wall. Depending on the volume of the tank, choose the appropriate number of brackets (they are usually followed) and dowels. There are 2 complete brackets to standard 100 liters. If the volume is less - it is also required 2, if more - 4/6.

On the reverse side, see how many holes on the boiler. Respectively. So much need to purchase brackets if they are not included.

Measure the distance between the holes and make the mark on the wall where you will do holes (standard 180 mm). If the wall on which the device carrying or in a panel house will be brought, then the perforator will need. In other cases, the electric drill will cope with it.

Be sure to check the straightness using the mounting level. The device must be installed absolutely without distortion.

He drilled holes, put a dowel and screw the brackets, after which the boiler hangs on the hooks.

How to connect the boiler to the water pipe

First, it should be noted that water coming from the water pipe is not distinguished by a high degree of purity. In order to be cleaned less often, it is recommended to embed a small filter on the input tube.

Now connect VN to the pipe with cold waterFor this, on the connector itself with a blue ring, we screw the safety valve and insulated with its fum-ribbon. After that, connect the pipe with a red ring with an output pipe, which will come to the mixer. Also isolated fum-ribbon.

For reference. FUM tape - insulating material on fluoroplastic base, which is characterized by high functional properties. The tape is not deformed when the temperature changes, does not rot, does not grind, does not break, labilic chemical elementsnot toxic.

In order for the carving "sat down" as thick as possible, it is necessary to wind up the ribbon strictly clockwise.

Connecting to pipes

Polypropylene pipes

What instruments will need:

• truborez

• tees and couplings (MRN)

• stopcock

How to connect:

1. Overlap the pipes of hot and cold water supply on the riser.
2. Make an incision on a marked pipe place and seserve tees on both pipes.
3. Insert additional pipes into tees (for elongation).
4. Mounted on the taps of the coupling and connect the locking cranes to them.
5. Depending on the remoteness of the boiler, connect the shut-off cranes with each of the nozzles or pave an additional flexible hose and connect with them.

In the photo you see how the connected device should look like

If the pipes are mounted in the wall, the connection will occur more complicated.

1. Catch the coating directly above each pipe.
2. Cut the pipe in the marked place and insert the repair clutch, more often it is called an American.
3. We welcome the clutch from the polypropylene to the tee, and to the cut on the pipe - a threaded end.
4. Remove the clutch and connect the pipes as indicated earlier.

Metal plastic pipes

All attachments on such pipes are carried out through fittings.

Procedure.

1. Overlap the water on the riser.
2. Cut the pipe cutter in the marked place.
3. Insert a tee, connect the segments of a metal-plastic pipe or a flexible hose to the mount and connect fittings with pipes.

Steel tubes

For reference. It is a sideline with a side threaded branch that allows you to make a hole in the pipe without special equipment.

In order to install it, it is necessary to clean the pipe from paint and spraying, put the rubber seal and fasten the clamp. It turns out a fully sealed connection. Next, through the branch, drill (the bushing comes in the kit) the hole and connect the shut-off valve, and the flexible hose to it is already connected to the water heater pipe.

How to connect a flow unit

PV is installed exceptional to the hot water supply pipe.

Procedure

1. Overlap water on the riser
2. Cut the pipe in the place where the connection will be, and weld the locking cranes on both sides.
3. Connect the output and inlet nozzles with locking cranes by means of flexible hoses.
4. Connect to electricity.

Using such a device in everyday life, first turn the water, after the boiler is turned on. At the end - first, the boiler, then water.

To understand exactly how it is right and in what order to perform actions, look at the educational video

Video - How to connect a boiler to the water pipe

Without hot water, you can not imagine comfortable accommodation in an apartment or house. In multi-storey houses, accidents often occur, hot water interruptions, planned shutdown, etc. As for private houses, the provision of hot water completely falls on the owners. Therefore, the purchase and installation of the water heater is sometimes the only possible solution to this issue.

The boiler connection is one of the most complex tasks, as it requires the connection of the aggregate from the highway, both cold and hot water. Highly important moment - Location of the boiler in relation to the pipes. It should be installed as close as possible, since the durability of the system depends on this. The quality of the materials used is also very important. Flexible metal hoses, plastic pipes, tees, etc. must be as high as possible. Do not save on materials.

Types of boilers

Water heaters are divided according to the principle of operation:

• flowing;
• cumulative.

The classification also goes to the following parameters:

• the size;
• the form;
• heating system (straight, indirect, combined).

Flowing boilers

There are deficiencies that make them not very beneficial for apartments in high-rise buildings:

• In such water heaters, there is no water tank, and water heating is carried out due to the heat exchanger using a Tan. This device requires high power and water pressure in the system. The minimum pressure in the water supply system must be not lower than 0.3 atm.
• When using a flow boiler, water will be low, and water will not be too hot.

Cumulative boilers

Such water heaters are much more popular. They are prescribed and non-pressure type. The basic minus of the non-pressure boiler is low water pressure. The advantage of such an aggregate is a stock of water in case of lack of it in the water supply system. Pressure in the pressure boiler is equal to pressure in the plumbing system.

Cumulative water heaters are also divided by water heating system:

• straight;
• indirect;
• combined.

Direct type water heaters work on the principle of a conventional electric heater, they are equipped with a Tan (water heating element). Tavtology of one sentence.

Tenny, in turn, are:

• dry;
• wet.

An indirect type water heater works at the expense of heat exchange between the coolant (heating boiler) and tap water. Significant disadvantage is that it requires the work of the heating boiler round yearAnd also requires the installation of a boiler in the immediate vicinity of the boiler.

The combined type of water heater combines the properties of direct and indirect types. IN winter Such a device can operate from the heating boiler, and in the summer on the principle of a conventional water heater. The combined water heater is the most profitable and convenient.

Both flowing and cumulative boilers are pressure and non-free. In the original units, there is no internal pressure - the pressure inside the water heater is almost equal to the atmospheric.

Pressure boilers imply high pressure inside the tank. As a rule, it is equal to pressure in the water supply system.

How to choose a boiler

First of all, you need to decide on your needs, namely:

• with installation site;
• form boiler (vertical or horizontal);
• volume (how much hot water you need);
• type of water heater (flow or accumulative).

You should also take into account the number of people in the family. The greater the family, the greater the required boiler. Also should be taken into account the purpose of the installation: if you need a boiler for the kitchen, then you can limit the small volume of 10-15 liters or 30 liters. If it is needed in a shower or bath, then the volume should be at least 80-100 liters.

Connecting a cumulative boiler

What to pay attention to when choosing:

• Case shape. It is the price that depends on it. Round boilers are cheaper, but take more space. Rectangular shape units are more expensive, but they are more compact and comfortable.
• Case material - steel or plastic.
• Color spectrum.
• The material from which the tank is made. Such material may be enameled or stainless steel. Stainless steel tanks better resist corrosion, but at the same time great importance It has the quality of the seams, since in places of welding, even stainless steel may be corroded.
• Tag type (dry or wet). The devices with dry ten are more expensive, but the wet shade has a number of significant drawbacks, as it works on the principle of the boiled. Both on the agent and on the inner surface of the tank, it is quickly formed, which leads to overheating and an increase in the consumption of electricity and a decrease in service life.
• Warranty support. This should pay special attention to this, since the provision of a long warranty may be a pledge of high quality. If there is no guarantee, it is better to refrain from buying - most likely the product is defective.
• Price. It is not worth buying too cheap water heater, there is a high probability that it will be poor and will last long.
• Massiveness. High-quality product weighs quite a lot. This means that the steel, from which the tank is performed is quite thick, respectively, the product is high-quality and last long.

What you need to connect

Tools and materials:

• mounting level;
• passatia;
• marker;
• cross screwdriver;
• 2 plumbing hose (flexible);
• 2 dowel-nail with crochet at the end;
• crane (valve) with a diameter of 10 mm (by diameter of the tap pipe);
• sanitary filament;
• adjustable key;
• roulette;
• perforator;
• safety valve (complete with boiler).

Schemes and drawings

As you know, the electrical man has two types of connection: to the water supply system and electric.

Boylera connection scheme

In order to correctly install the unit and at the same time comply with security measures, there are schemes. They are made in the form of drawings with the designations of the main elements of the system. There are two types of schemes: mounting and electric.

Mounting scheme

It shows schematically the main parts of the system, their sequence and location. This example shows the installation sites of the locking, cranes of tees, the check valve, schematically shows the circulation of water in the system (inlet of the cold water and the yield of hot, its feed to the mixer) such a scheme can be found in the factory instruction, which is attached to the aggregate.

Classic mounting scheme:

• Stop valve.
• Mechanical cleaning filter.
• The tee on the plumbing cold tube (leads to the boiler and to the mixer).
• The second shut-off valve on the approach to the boiler.
• Safety valve that prevents water leakage in the opposite direction.
• Tees that are connected directly to the boiler - one for the input of cold water, the second to exit hot water to the mixer.
• Water lines scheme.

Boylera connection scheme

Electrical circuit

The electrical circuit shows:

• The wiring leading to Baku (originates from the electrical panel).
• Three wire lines (zero, phase, ground conductor). In the diagram, they are always marked by different colors.
• System elements: fork, ground socket, double automatic (switch). This is a mandatory element that makes it possible to completely turn off the water heater from electricity if necessary.
• The location of the meter, electrical panel, and also schematically shown grounding.

All this is depicted using conventional designations, the decoding of which is necessarily attached to the scheme.

Installation and connection process

Fastening the boiler stages:

1. Choosing a place where the water heater will be. It must necessarily provide access to it for the entire period of its operation.
2. Estimation of the state of the electrical wiring and pipeline. The wiring must withstand the load when working the boiler, and the state of the pipeline must meet the requirements for the operation of such equipment.
3. Drilling holes for fastening the water heater, after which the fasteners are installed, the boiler is attached using anchors and dowels.

Connect to water supply

1. Before connecting the boiler to the water supply system, it is necessary to output all the necessary tees in order to ensure water supply both to the boiler and from it to the mixer. If desired, the filter is placed.
2. Next, you should pay attention to the tubes that are located at the bottom of the water heating tank. Usually they have identification rings: blue - cold water; Red - hot water. It is necessary to attach a safety crane to the tube with a blue ring - it can go bundled with a boiler, and can be bought separately. Installing such a crane is obligatory!
3. Before attaching a safety crane, a sanitary liner should be hounded or a sealing tape.
4. A flexible hose is mounted on the safety valve.
5. The second flexible hose is attached to the tube with a red ring.
6. The next step is to secure the second end of the flexible hose, which is attached to the safety crane. At the same time, its second end is attached to the plumbing pipe - this line water from the water supply will enter the tank. Before fastening the soft hose, you should put a faucet so that it is possible to overlap the water supply if necessary.
7. The free end of the flexible hose (attached to the tube with a red ring) must be combined with a pipe that leads to the mixer. This hot water outlet line from the tank and feed is on the mixer.

Connecting to the electrical stroke

What will take:

• Distribution shield.
• Cable required length and sections (three-core).
• Circuit breaker on 16a.
• A protective shutdown device (UZO), designed to work with a current force of more than 16A.

Sequence of work:

1. Cable for switchgear (cable cross section should be at least 2.5 mm, copper veins).
2. Connecting the UZO (protective shutdown device) - this device will be protected from electricity damage in the event of a boiler fault. Uzo often comes complete with the boiler itself.
3. Holding electric cable From the shield to the boiler.
4. Installation of the circuit breaker (double), which should be calculated for the current current of at least 16a. It protects the network from current leakage through insulation damage.

When installing the boiler, a double circuit breaker must be installed. If we are talking about a private house, then the presence of a grounding circuit. This is dictated by the safety regulations.

Due to the fact that water heaters are represented in a variety of options suitable for any needs, you can not be afraid of hot water. It is water heaters that guarantee convenience under any conditions. Their work does not depend on either weather conditions or utility services. Even if there is no centralized provision of hot water, if you have a boiler, it will always be in your home.

To make an independent connection of the water heater to the water supply, the diagram of which is attached in the passport of the product, maybe if desired, each user. To understand how to properly connect the device to a home water supply network, it suffices to study the selection of heated water from the tank and act according to the instructions in accordance with the scheme. The procedure does not apply to particularly difficult, and it can be done even alone, except for the installation of the water heater with their own hands on the wall will require extraneous assistance.

The principle of water selection from the tank

There is one right scheme for connecting a cumulative water heater, which takes into account the features of its design and allows you to quickly empty the tank if necessary. Such a need arises for the following reasons:

• planned cleaning of a tank and a tan from scale;
• the emergence of a malfunction;
• moving or replacing the device new;
• emptying the water heater in the country or in a house with periodic heating in the winter.

Connecting the water heater to the water supply, the diagram of its installation and placement should take into account that water selection is carried out from the upper tank zone. This is due to the fact that at the top the water is the hottest, and in the lower zone is replenished with a cold stream in the presence of water development in the DHW system. The selection occurs through the vertical tube, the cut of which is located in the upper zone.

It is impossible to allow water from the container to return to the cold water supply system, so connecting the boiler to the water supply is performed through the check valve. When the pressure is dropped in the network as a result of a water disconnection, the valve will not give the contents of the tank to the pipe.

As a result of the standard connection of the boiler to the water supply, it will not be possible to empty quickly by opening the crane of hot water. Even unscrewing the DHW pipe from the fitting will not give an effect, as the water fence is located too high, and the reverse valve is on the cold. The plum problem solves a simple diagram of connecting the water heater to the water supply, collected at the installation stage of the device.

What will required for installation?

Before installing an electric or gas boiler, it is necessary to highlight it appropriate place Taking into account the following points:

• the placement of the water heater in an apartment or a private house must be done taking into account the convenience of use and maintenance;
• it should be noted that with emptying or repairing the apparatus, a significant part of the water can shed at the floor;
• connecting the water heater on your own convenient when water and electrical network It takes place nearby and in the same room;
• installation and accession of the gas boiler with their own hands implies a liner to the indoor room supplying natural gas.

Based on the listed conditions, the installation and connection of the accumulative water heater can be performed in such premises of the private house or apartment:

• kitchen - over washing;
• bathroom - over the bathroom;
• boiler room - over the tiled floor.

Before resolving the question of how to connect a boiler to the water supply, it is necessary to suspend it to the wall. To perform all the work, you will need an electric drill with a shock function (or perforator), drills with carbide attacks and a standard set of plumbing tools, including gas and adjustable key. The boiler connection scheme is assembled from such elements and materials:

• the valve is reverse with safety in one case (as a rule, it comes in a set with a boiler);
• tee bronze Du 15 (1/2 ");
• crane ball Du 15 (1/2 ") - 3 pcs., 2 of them - with an American;
• pipes for compound (usually metal-polymer);
• FUM tape, flax or special thread for sealing joints.

There is an electrical scheme for connecting a boiler, in accordance with which it is necessary to purchase differential circuit breakers for a current of 16 A (2 pcs.), A socket and a plug with grounding contact, as well as power cable required length. The attachment of the natural gas apparatus is carried out by means of a gas hose.

Independent system assembly

The procedure begins with the wall mounting of the device, and after the question is solved how to connect the accumulative water heater. Since the boiler has a significant weight, it is better to put it with an assistant. When installing, regular fasteners and anchor bolts are usually used or other devices, if the wall is wooden or is a frame, covered with plasterboard.

To connect the water heater with your own hands to the plumbing network, overcoat the water supply in the house and follow the instructions:

1. To the fitting of cold water supply (it is painted in blue colour) Screw the tee, and it is a regular check valve to it (it is the safety valve).
2. Connect the ball valve without an American. For ease of emptying to it, you can fasten your knee 90 ° with a hose fitting.
3. Below the check valve, put a ball valve with an American. The same set the hot water supply branch (marked in red on a water heater).
4. Complete the installed reinforcement with a cold and hot water system.

If the boiler installation with her own hands was produced in a boiler room or a different place, where there are no sanitary devices under the device, the safety valve fitting should be connected to the sewage output with a flexible tube.

With absence sewer system The tube is lowered into transparent plastic bottle or canister. During the operation of the unit, the heated water expands, and its excess is slowly coming out through the spout of the safety valve.

Thanks to the collected joining scheme, the boiler is easily emptied through a tee with a valve. Before draining, the cutting crane of cold water is overlapped, and hot - opens. It is also necessary to open hot water on the nearest mixer, from there leave a maximum of 2 liters. Then the crane on the tee opens, and there is a drain from there, the place of water in the tank takes the air entering the mixer. Filling capacity is easier: it is necessary to open a cold cutting faucet and wait until water runs out of the previously earlier mixer. But before, do not forget to close the valve on the tee.
