How to install the boilerAmong all the benefits that are available in a modern apartment and a private house, there is always hot water. Unfortunately, today it is still possible to meet such sleeping areas and private buildings, which are not connected to the central hot water supply. And trying to get out of such a difficult situation, many owners are beginning to consider the option of installing an autonomous hot water system.

However, there is an easier solution to this problem - installing a boiler with your own hands. Due to the fact that the vast majority of homes are electrified, installing a water heater in them becomes quite simple by providing yourself with hot water.

Regardless of what type of electric boiler installation, the owner has thought about - running or accumulative, it is quite simple to do this work on his own. Such devices have different capabilities, which is determined by the capacity of their tank. So, if you stop the choice on the installation volume of 10-15 litersthen it will be enough to provide hot water for a small country house that does not have a bath or shower, and also where a washing machine and dishwasher are not used.

If the task is to provide hot water to a house or apartment where a shower stall is installed, then a model with a capacity of up to 50 liters can help in solving it. If you have a bathroom, you should think about purchasing a device with a volume of 80-100 liters.

Important nuances of installing a boiler

Starting installation of an electric water heater with your own hands, you should decide on the most appropriate place for its placement and conditions that must be met in order for the instrument to ensure proper and safe operation.

Installation Features

  1. Features of the boiler installationInstalling a water heater with your own hands should be done in such a way that you can easily get to it and the nodes controlling its operation, and perform repair or maintenance of the nodes.
  2. The installation site of the water heater can be only a load-bearing wall or a partition that can cope with a double load of weight. In other words, if the owner purchased a model with a capacity of 100 liters, then it should be designed for a weight of not less than 200 kilograms.
  3. Attention should be paid to the wiring in the room, which must cope with the full load. If the work is carried out in an apartment where the wiring has not been changed for several decades, then It is desirable to bring a new cable of sufficient capacity to the water heater, taking care of its grounding For example, if the power of the water heater is 2 kW, you will have to lay a copper cable, the cross-sectional area of ​​which should be 2.5 square meters. mm, or it can be replaced with aluminum wire with a cross section of 3.5 square meters. mm
  4. An inspection of the water pipes should be carried out to assess their condition. In case of damage, it is advisable to replace the pipes before installation by installing a metal-plastic pipeline.

Materials and tools

Still prior to installation water heater with their own hands should take care of the availability of the necessary tools and materials:

  • What tools are neededThe puncher with the drill with a diameter of 10 mm, a tape measure, scissors for trimming metalplastic pipes or the Bulgarian.
  • Wrench 24 x 27, 19 x 22, gas or adjustable wrench.
  • Screwdriver flat and cross, flat-nose pliers and nippers.
  • Oiled tow, mounting paste or FUM tape.
  • Shut-off valves - when installing a cumulative boiler, one will suffice;
  • Tees with a diameter of 0.5 inches - to make the exact choice, you should consider the type of installed boiler. It is possible that during operation you will have to use adapters with a diameter of 0.5-0.75 inches.
  • Flexible reinforced hoses.
  • Metal-plastic pipe - to determine the length of the pipeline should proceed from the specific installation conditions.

It should also be ready for laying new wiring or power line. To carry out these works will require:

  • Three-core cable, corrugated hose.
  • Automatic switch or socket.

After preparing the tools and materials, you can proceed to the installation of the water heater and the assembly of pipes and valves.

Connecting cold water and hot output

How to install and connect the boiler correctlyHaving decided on the option of a water heater and preparing the necessary consumables and tools, you can start the installation do it yourself Keep in mind that to carry out this work you do not have to obtain permission from utilities, develop projects and provide other documentary evidence. In practice, all operations for connecting the device in the heating system are quite simple.

When choosing the location of the water heater it is necessary to proceed from the location of the water meter, behind which the water heater will be placed. Let's say the boiler can be installed where the toilet cistern valve is located. During pipe routing, elements with a diameter of 0.5 inches are most often used. To start tapping tee should be only when the owner is satisfied that cold water does not flow to any point of consumption in the apartment.

The procedure for installing a hot water supply line is carried out by installing a standard fitting. 0.5 inch diameterfor which space is reserved immediately behind the valve. A feature of fittings, nuts and valves is the presence of right-hand thread. With this in mind, twisting should be done in a clockwise direction. When performing work on the installation of hot water, it is allowed to use standard fittings, the diameter of which is 0.5 inches or 0.75 inches. The final choice is made individually by the owner, who should take into account the nature of the location of the pipes in the apartment.

Based on practical experience, on average, inexpensive fittings are no more than 3 years. For this reason, it is recommended to give preference to valves having a high-quality design. Obligatory operation is the packing of threaded connections, which is performed using flax tow in combination with mounting paste, which can be replaced with fum tape.

Installation and connection of the water heaterWork with tow and fum tape involves winding them in a clockwise direction. If tow is used, then it is quite possible to do with 3-4 turns, in case of using the tape, 15-20 turns will suffice. If the material turns out to be too much, it will come out on its own during the twisting. Take care that the cold water inlet fitting is equipped with a non-return valve - a similar element is usually supplied with the water heater.

The valve is mounted by screwing it onto the coupling. Similarly, a fitting should be installed at the outlet fitting, which provides a connection to the outlet pipe. In a similar way, the adapter is installed at the outlet with hot water.

Having completed the installation of fittings, you can go to the heater mount on the wall and connecting pipes for cold and hot water. When joining pipes to fittings, you should make sure that they are the first to go into it as far as they will go. This will be easier to do if you preliminarily light flare the trimmed end. When it is time to tighten the nuts on the fitting, do not over-press, otherwise it will break the non-ferrous metal nut.

During the crimping, do not immediately tighten the nuts, which is especially important when detecting undermining. This can be done upon completion of the operation. In order to create an inlet and an outlet for a boiler, ball valves are used to demonstrate increased operational reliability.

Connect the water heater to the mains

How does the water heater workMost often this work is done with the help of cheap cable made of copper brand SHVVPwith a cross section of 2 x 2.5 millimeters, connected to a network of 220 volts. Such a cross section of the wire will be enough to cope with a load of up to 20 amps. If you plan to install a device with a power of 1.2 kW, the current load will have a value of 5.45 amperes. The installation of the cable, enclosed in a corrugated self-extinguishing hose, is carried out on the wall using dowels "quick installation", having L-shaped studs. The parameters of the dowels and studs should be as follows: the diameter of the first - 10 millimeters, the diameter of the second - 8 millimeters.

Another method of mounting the cable is to place it in a pre-created strobe. This operation is performed using a perforator equipped with a pointed peak. Also, instead, you can use a grinder with a diamond wheel. So that the operation of shaving is carried out with less labor, you can resort to using joints of concrete slabs. Cable installationI section 2 x 2.5 millimeters performed in such a way that it starts from the place of installation of the heater and ends at the machine, from which the gasket is continued directly to the counter.

Before starting to connect the device to the electrical network, you must make sure that the apartment is completely de-energized. When connecting the cable supplied to the heater, use special terminals in the boiler, and the operation itself is performed using a cross-head screwdriver. Many models of storage heaters are equipped with a thermostat, which allows them to demonstrate increased efficiency.

After completing the above operations, proceed to commissioning. First of all, it is necessary to fill the capacity of the water heater with cold water, for which purpose one should turn the ball valve located behind the tee on the drain tank. After that, you need to rotate the screen on the hot water line. This will allow air to escape from the reservoir in a natural way, allowing the water to fill in the free space. It is imperative to turn to the open position the mixer or faucet for hot water at any of the consumption points in the house.

Making sure that the water heater with a full tank started working and water flows from the mixer, the tap is closed. Due to the water in the boiler tank, a slight pressure is maintained, so it is necessary after one to two hours to look at all the connections for leak detection. If drops are found at the joints, it is necessary to tighten the nuts on the fittings.

Stationary or temporary installation?

How to install a boilerAt the installation stage of the electric flow type water heater, the owner has the opportunity to choose stationary layout or temporary. This device provides this opportunity due to its mobility. To implement a temporary water connection option, you will need an ordinary shower hose. This job comes down to tee tie-in inlet pipe, from which cold water flows. In turn, the tee is connected to a flexible hose using a fitting. For any installation option, it is mandatory to perform a tie-in valve in front of the tee.

The stationary connection of the electric flow or storage tank is able to provide simultaneous cold and hot water. With this option, the work is performed simultaneously with the installation of the main water supply system. The essence of this installation is to insert tees into the tube and to place valves on each of them. When using this method of connection, it is possible to avoid installing an electric boiler in the water supply system. TEN is used to connect to the cold water pipe, and hot water is discharged at using a flexible reinforced hose or a metal-plastic pipe, which is connected to the stop the valve.

Conclusion

Thus, the installation procedure of the electric flow and storage boiler is not difficult. If you strictly follow the order of work and have all the necessary materials and tools, you can solve the supply problem hot water with minimal cost. Special attention should be paid to equipping the installed system with the necessary components, without which it is impossible to count on the effective operation of the device.
