More and more people are becoming convinced that an autonomous way of heating an apartment or house is more economical than a centralized one. Do-it-yourself steam heating is one of the hardest tasks, but quite doable if you have some basic power tools skills. Even before the installation, it is necessary to make calculations and purchase the necessary components.
Some get confused and believe that in fact, the correct name of such a system is water heating, and the prefix "steam" remained from the past times when heating was carried out at the expense of industrial boilers that produced large volumes of steam. In fact, even today there are boilers that provide space heating by converting the fluid into two states of aggregation. The strengths of this solution are:
Some disadvantages are:
The essence of the operation and high efficiency lies in the fact that the steam, passing through the main line, condenses and settles, thus producing a large amount of thermal energy. At the same cost of fuel, such a system will be much more efficiently similar in length to water.
Usually, in order to ensure the safety of users, in modern boilers there are certain restrictions. For example, the maximum temperature to which the steam is heated is 130º C, and the highest point reached by pressure is 6 atmospheres.
All types of systems are divided into single-circuit and double-circuit. In the first embodiment, all the power of the boiler is used to heat the carrier, which will take part in increasing the air temperature inside the room. In the second variant, there is an additional heat exchanger, in which the flow of running water is heated, which allows it to be used for domestic needs. When implementing the second option, it is worth remembering that it will be necessary to make additional connections to the boiler room and return them back to the living room.
Different heating systems
By the method of circulation of the carrier, as in the case of water systems, there are :
According to the level of pressure inside, there are:
According to the method of distributing pipes, the following are distinguished:
One-pipe heating system
Two-pipe heating system
Vacuum systems are still at the testing stage. When using them, the constant availability of electrical energy will be necessary, since the vacuum pump operates almost continuously.
Choice of boilers
In order to properly pick up the heater, the first thing you need to calculate the area that will be heated. To do this, you need to calculate the area of each individual room by multiplying the width by the length. After that, all the results must be added, the final figure will be the desired value. It is important to remember that this is true for ceiling heights of up to 3 m, if it is larger, then it is necessary to make additional headroom.
The next step is the choice of fuel. Steam boilers easily operate from the following sources:
In some cases, solid fuel solutions cost much less, but you should consider not only the cost of fuel, but also the time that will be spent on kindling. In this case, it can reach several hours, while it is necessary to constantly replenish the furnace in order to maintain the temperature at the proper level.
Some manufacturers combine different fuels. For example, they combine a furnace for loading solid fuel and provide the presence of heating elements. At the same time, efficiency does not fall, but it turns out to save on costs, and therefore on payments.
Types of pipes
When you select, there will be a lot depend on the planned budget. What can be said for sure - for systems of this type polypropylene pipes are by no means used. It is explained by their instability to high temperature conditions. You will need to choose from the following options:
Straight-seam steel pipe
When mounted, pipes can be hidden in walls or floor. But it is important to take into account that the building material is resistant to thermal effects.
Cast iron batteries
Except for the boiler and pipes for the highway, mandatory elements are required, without which it cannot be avoided:
The installation of an indirect heating boiler is possible in the steam heating system. You will need a valve for three inputs. It connects to the thermostat and redirects the movement of the coolant.
Scheme of the heating system in the house
First business will need to make a drawing. On a sheet of paper is applied to the floor plan in which the installation will be carried out. The location of the boiler is determined. It is desirable for him to allocate a separate room. This is done in order to ensure maximum safety. If it is a closed system with natural circulation, then it should be at the lowest point. This is necessary so that water can flow freely to it.
The wiring of the entire system is applied, as well as the location of all the elements that were listed in the previous section. When performing this step, it is better to be in a particular room, then it will be possible to plan everything in the best possible way, taking into account the need to bend around the pipeline around obstacles or projections. All corners and transitions should be noted on the diagram. Once the drawing is completed, you can most accurately calculate the material that will be needed to successfully complete the entire project.
Some craftsmen make a steam boiler themselves. It is either boiled from sheet material, or a special contour is made from pipes, which is laid inside a brick stove. In the second case, it will be necessary to monitor the condition of the heat exchanger, which is best made of stainless steel, which will extend its service life. It is also very important to clean the smoke paths more frequently.

According to the marking done on the diagram:
In this article, we discussed in detail how to make steam heating private houses. We would love to know about ready and functioning projects. Share your experiences and observations in the comments.
When installing heating in a wooden house, you need to take into account the specifics of such a structure.
