The duration of the cold season in our country poses a number of pressing issues for the inhabitants of private houses related to the organization of normal and efficient individual heating. For residents of the private sector in cities and towns of the country, the issue of organizing autonomous heating has been largely resolved through centralized gas supply. A completely different situation has developed with objects of individual residential development. Quite often, due to the lack of central gas supply, for homeowners in the private sector and in country houses, the only way out of this situation is to install autonomous heating boilers on solid fuel.
Heating solid fuel boilers, which are produced today by domestic and foreign manufacturers, are complex high-tech devices. Proper installation, compliance with the necessary rules during the subsequent operation of complex heating equipment will allow you to create the necessary comfort in your home and provide your home with the desired warmth during the long winter.
The most crucial moment is connected with the installation of equipment and its connection to the home heating system. Solid fuel boilers of different types have their own design features, so during installation it is necessary to strictly follow certain rules and comply with the project. If you can figure out the choice of a boiler model on your own, then the question of how to install a solid fuel boiler cannot be answered simply and unambiguously. Work on the installation of any heating device requires competent actions and a qualified approach. Let’s deal with this task in detail.
Training. What precedes the installation of a solid fuel boiler
Assessment of the scope of the upcoming boiler installation work
The initial preparatory steps that precede the direct installation of boiler equipment are no less important than installation work. Any boiler, gas, electric or solid fuel, is a mini-boiler room, so the installation of the unit is preceded by the design work of the entire heating system.
Buying a solid fuel boiler is just the tip of the iceberg. In the future, it will be necessary to perform a large amount of work for the equipment of the entire heating system. The complex of works on autonomous heating equipment includes the following stages:
- laying pipes inside residential premises;
- boiler room equipment;
- binding of the heating unit;
- starting the heating system.
Assessing the scope of work at each stage, we can conclude that the installation of a solid fuel boiler in a residential building is a complex, time-consuming and responsible process.
Important! Installation of an autonomous heating system, in particular, installing a boiler, is a task that only a trained person can do. Superficial knowledge about the design of heating equipment, neglect of existing standards, norms and rules can cause irreparable harm not only to a residential facility, but also endanger the lives of the inhabitants of the house.
Approximately such a set of fixtures and equipment you will need to connect a solid fuel boiler at home.
At the preparatory stage, it is necessary to decide whether we do the heating in the house with our own hands or turn to the services of professionals.
We make a decision — we put the boiler ourselves or turn to specialists for help
A solid fuel boiler is usually purchased based on the existing conditions, where and how the boiler will be installed, in what mode the heating unit will operate, what tasks are set for the autonomous heating system. Having a ready-made project at hand, you can evaluate what you will encounter during the installation of boiler equipment. Therefore, a reasonable question arises — you can install a solid fuel boiler in your house with your own hands, or it is better to turn to professionals.
Only self-confidence and the ability to save your own money can encourage you to make the decision to independently install the heating system in the house.
For reference: the equipment of a solid fuel boiler room, including firewood, coal and pellets, can be carried out without official permission. Only during start-up tests, the presence of representatives of the supervisory authorities is necessary to register the commissioning of heating equipment.
When installing a boiler in your home, you must remember that in the process of work you will need to strictly adhere to the design data. This applies, first of all, to the ventilation and chimney systems. Properly executed exhaust and chimney — a guarantee of uninterrupted operation of the boiler in accordance with the specified modes. Pellet burners are installed in a solid fuel boiler to increase heating efficiency, but are very sensitive to ventilation.
Before installing the heating equipment, it is necessary to calculate the parameters and equip the boiler room.
Installation of a solid fuel boiler. step by step
Boiler room equipment
To begin with, assuming to install a solid fuel boiler in your home, you should know that this equipment is available only in a floor version. Do-it-yourself installation of a solid fuel boiler will require you to spend and effort on equipping the boiler room and, accordingly, prepare a special site for the unit.
For this purpose, you need to know your house well in order to choose the optimal room for installing the boiler. The project documentation should contain a diagram of the location of the boiler room in the house. The base for the heating boiler or podium must be of appropriate size and strength. Usually such platforms are made of concrete. The height of such a podium must be at least 7 cm.
The room itself must have an area of at least 7 square meters. m. The boiler should be located at a distance of 0.5 m from the nearest wall of the room. The height of the boiler room should be standard, approximately 2.2-2.5 meters, while the distance from the upper edge of the boiler to the ceiling should be at least 120 cm.
On a note: the only condition, if you installed a boiler with a natural ventilation system, then you will have to think about the height of the ceiling in the boiler room. The flow of air in this case is carried out due to the air masses inside the room. The higher the ceiling, the greater the internal air volume. Remember also the fact that it is more difficult to load the boiler with fuel in a low room.
The installed boiler needs fuel, so next to the boiler it is necessary to equip a place for fuel storage.
Important! Only dry fuel is loaded into the furnace for storage.
A coal pit is specially made for coal. Pellets, briquettes and firewood are stored either in containers or neatly stacked pyramids. The walls in the boiler room must be treated with an 8 mm layer of asbestos. or a thick layer of plaster, thereby protecting house structures. This is especially true when installing a heating boiler in a wooden house.
Retreat: in a number of cases, today traditional boilers are being converted to use pellets. This type of fuel is very convenient and efficient. Pellets are automatically fed into the combustion chamber. In the process of burning this type of fuel, a high thermal effect is achieved, which is very important if a long-burning solid fuel boiler is installed. Installation of a pellet burner is carried out on any solid fuel boiler. This method of operation of the boiler significantly increases the efficiency of heating equipment, especially since the burner can be easily removed if there is a desire to transfer the boiler to the usual fuel, wood or coal.
After preparing the boiler room and foundation, the most difficult and crucial moment lies ahead, the installation of a heating boiler. All the complexity and difficulty at this stage lies in the fact that usually solid fuel boilers are heavy and massive units. Here you need to apply maximum skill and skill.
Working on ventilation and chimney
Any autonomous heating system needs a constant supply of fresh air, which ensures proper combustion of the fuel. Solid fuel boilers, the design of which is based on the furnace principle of operation, must be equipped with a chimney and a ventilation system.
Installing a solid fuel boiler in the house will require you to make additional efforts to create exhaust and supply openings. The first, supply hole with a section of 10×10 cm is equipped at the bottom of the room, opposite the chimney. The second hole is made at the top of the boiler room, the higher the better.
The chimney must be equipped in accordance with the parameters specified in the data sheet of the heating boiler, i.e. it is necessary to accurately select the diameter and length of the chimney pipe. A properly made chimney provides good draft, due to which carbon monoxide, soot and soot are removed.
Important! Excessive draft can adversely affect the regulation of the combustion process of the flame in the furnace and vice versa, weak draft will cause combustion products to enter the living quarters.
The ventilation and chimney installation diagram is shown in the figure. Every setting and size matters. To date, there are a variety of designs of ventilation systems for private houses, starting with brick, massive structures, ending with coaxial chimneys.
Expansion tank installation and piping
For a solid fuel heating system, it is important to install an expansion tank. Such a device performs the function of a compensator, with the help of which, after turning off the boiler, the temperature of the coolant in the circuit decreases. Open tanks are the easiest option with which you can solve the problem of the heating system cooling down as soon as possible. No shut-off valves are installed on the pipe going to the expander, and the pipe must be at least 25 mm in diameter.
After installing the expansion tank, the piping begins. The scheme for connecting the boiler to the pipeline system is carried out in accordance with the technical documentation. First, the main circuit is connected, then the return is connected. If provided in the house for hot water supply, it connects the hot water pipeline.
Important! A closed circuit must be equipped with a safety valve, which is installed with the outlet manifold. The task of the safety valve is to operate at an operating pressure of not more than 0.15 MPa.
Installing heating from a solid fuel boiler in a private house involves the use of steel pipes for the pipeline. It is necessary to lay pipes with the least number of turns and bends. The pressure pump is usually cut into a parallel line, in case of a power outage for natural circulation. As a means of protecting the system from overheating, there is a second or spare circuit, through which heat escapes in the event of an emergency to the storage tank for hot water.
The connection diagram of the boiler to the heating system is carefully checked before starting. The main emphasis is on the operation of ventilation devices and pipeline connections to the heating device. If you decide to install a solid fuel boiler with your own hands, perform all subsequent procedures and manipulations, follow the advice of experts and professionals. How to properly install an autonomous heating system in your home, how to equip an exhaust hood and build ventilation, you will have to independently look for a competent answer to these and many other questions.
