Installing a boiler with your own hands is not a complicated process, but it has its own characteristics. Requires the availability of a special tool and a soldering iron, you can buy it in the sanitary ware shop.
Preparatory work before self-installation of the boiler
Installing a boiler is a fairly simple process, but it is necessary to observe many nuances when implementing it. Otherwise, it will not work, or it will quickly fail. Before proceeding with installation, you should reproduce the wiring diagram on paper - where hot and cold water will be embedded.
Also before starting the installation of the boiler it is necessary:
- to make room for the boiler itself;
- check the strength of the wall - the stock should be double (if the boiler is 50 liters, then the fastener is needed per 100 liters);
- determine the type of wiring (copper / aluminum) and the cross-section of the cable laid in the walls - the water heater is a very powerful consumer;
- check the condition of the water pipes.
Installation of the boiler must be carried out by two people, since this process is rather laborious. That is why it is desirable to free up the maximum amount of space for work. This will save time.
Often, the walls in old houses are not very strong. It is necessary to check them. This is done as follows:
- installation of the fastener on the wall is carried out;
- A pair of bags with cement is suspended on the hooks.
If the fasteners can withstand, then you can safely hang on it the load is half the size of the test.
Before installing the boiler yourself, you should check whether the cross-section of the wiring laid in the walls is large enough. For example, a copper cable with a cross-section of 2.5 mm2 or more is required to connect a water heater with a power of 2 kW. If overloaded, the wiring may begin to melt. This threatens the occurrence of a fire.
To connect the water heater, it is necessary to cut into the pipes. Often their condition, especially in old homes, leaves much to be desired. Therefore, it is not uncommon for those wishing to install a boiler that it is also necessary to change the pipes in the apartment at the same time.

Independent installation of the boiler is possible only with all the necessary tools, including:
- a set of drills;
- locking and swivel keys;
- a set of screwdrivers of various types (spline and cross);
In addition to tools, materials will be required without which it will be impossible to install the boiler:
- tow (or other type of winding);
- fum ribbon;
- shut-off valves (3 cranes);
- tees (3 pcs.);
- connecting hoses of sufficient length;
In the event that you need to replace a part of the wiring, you need to stock up the following items:
- 3-core copper cable with cross-section not less than 2.5 mm2;
- outlet block with ground;
- insulating tape;
Installing a storage boiler
In order to learn how to properly install a boiler, it is necessary to read the attached documentation. Since each model has its own characteristics, all of them must be taken into account during installation. Most often in the apartments installed storage water heaters, because they consume less electricity, and their cost is low.
The installation of the boiler itself is carried out in the following order:
- The wall is marked out, on it the fixing armature is mounted;
- the water heater is placed on the wall;
- tapping into the water supply;
- The container is filled with water, the absence of leaks is checked;
- power is supplied, the operation of the device is checked.
The marking is carried out using the usual chalk. After the fixing points are marked, drill the holes into the wall with a perforator. Further, with the help of a kayak or a conventional hammer, dowels are jammed. They hang hooks or other fasteners, which comes complete with a water heater. The number of holes that need to be drilled can be 2 or 4.
It is very important to take into account the height of the water heater. Since it often happens that the distance from the fasteners to the top of the housing is very large. And, having missed, you can easily not fit the heater in height. Therefore, before you start marking, you should use a tape measure and check the height.
In order to learn how to install a boiler by yourself so as to avoid the subsequent breakdown, it is necessary to contact experienced locksmiths. Also, you should use their help if the water pipes are rotten - you will need to completely replace them. If the pipes are in order, then the connection of the boiler will not cause any problems.

Conclusions for hot as well as cold water are indicated by red and blue colors, respectively.
If there are no pre-assembled bends for connection, then you must mount them yourself. This will require a plastic or polypropylene pipes, as well as a couple of hours of time.
Particular attention should be paid to the valve that relieves excess pressure. It must be installed correctly, the correct direction of the water flow should be selected.
