Wood boilers for home heating are still popular, despite the diversity of models of gas and electric boilers, and there is a simple explanation: Firewood is the most accessible type of fuel for country housesnot connected to the main gas. The efficiency of modern wood boilers is quite high, their efficiency reaches 85%, while not only firewood can be used as fuel, but also pellets, as well as woodworking waste.
Wood boilers used for the heating of a country house are easy to connect and use - to handle them even easier than with the stove. When complying with the installation and operation rules, they are safe. The only serious disadvantage of wood boilers is a low level of process automation: the boot of fuel into the boiler must be done manually. The way out of the situation can be a boiler with a function long burning or a combined boiler, working on solid fuel and having an additional diesel or gas burner or electric tan.
Despite the huge selection of models of wood boilers, the device varies not so much. Any wood heating boiler home necessarily has a fuel combustion chamber, a water heat exchanger, chimney and a ash bar. The simplest wood boiler on the device resembles a bourgear with a water shirt: when combustion of firewood in a firebox, water is heated and enters the heating system. The effectiveness of such a boiler is small, and the consumption of firewood is significant, due to incomplete fuel burning, part of the money flies into the pipe in the literal sense of the word. The design of modern boilers with a long-burning function, of course, more complicated, the device of such a boiler and its basic elements are shown in the figure.
Firewood in the boiler is loaded through the upper loading door immediately in a large volume. The initial burning of fuel occurs in the gasification chamber. Air intake, and with it and necessary for combustion of oxygen, in this chamber is limited - so regulated intensity of burning. In this mode, firewood is not lit, and they are smoldering with the formation of more heat, while water is heated in the heat exchanger. But the combustion process does not end: when it is formed by smoke containing combustible gases. These gases fall into the second chamber - the combustion chamber, which is simultaneously as a roller. Air supply to this camera is no longer limited, and with sufficient amount of oxygen, gas survivation occurs. The combustion temperature of the gas-air mixture is very high, and the effectiveness of the heating of the water heat exchanger in this chamber too. As a result, the smoke is cleaned from ash and harmful combustible gases, which makes the new generation wood boilers very environmentally friendly.
Pyrolysis - the process of long burning
Smoke disharma is carried out through the chimney channel attached to the chimney and the pipe. To supply cold and removal hot water From the heat exchanger, the boiler is equipped with nozzles. They are connected to the heating system by the selected scheme. New generation boilers are equipped with automatic, which allows you to simplify the boiler maintenance as much as possible:
The effectiveness of solid fuel boilers directly depends on the type and quality of fuel. If the boiler is designed to work on firewood, it is impossible to load coal and peat briquettes into it! This will reduce the efficiency of the boiler and can bring it out of order. It is also not recommended to use poorly dried firewood and wood for firebox coniferous rocks - They are lit with the formation of a large number of steam, resins and soot, and the boiler will have to be cleaned much more often.
Selecting a wood boiler must begin with the calculation of the required power - this parameter is indicated in the passport on the boiler and is measured in kilowatts. One kilowatt boiler power is enough for heating ten square meters of well insulated room. For example, in the middle strip for heating at a house of 100 square meters, a 10-kW boiler is required. For frosty days and poorly insulated rooms, a capacity of a capacity of 20-30% is required. When choosing, it is worth paying attention not only to the nominal power, but also on the entire range in which the boiler may operate - in the fall and in the spring it is impractical to drown a boiler for full power. If you plan to use the boiler also to get hot water, then you will need an external boiler and an additional reserve of boiler power in the amount of people constantly living in the house.
An important role is played by the material of the boiler - steel or cast iron. Steel boilers are easier and have more simple design The furnaces that make it easier to clean - just remove the ash from the ash bar. The smoke canal in steel boilers is longer, so heating the coolant is more efficient. Cast iron boilers smoke canal is shorter, and a large area of \u200b\u200bheat exchange is achieved at the expense of a ribbed surface, in which the combustion products are settled, clean the pig-iron boiler will have to use brushes, scrapers and a kocher. In this case, the heat capacity of the boiler itself in cast iron models is higher.
An individual type can be distinguished by electric wood boilers, which with the help of electricity even more increase efficiency. Modern automation monitors the combustion process and affects it using valves that adjust the flow of the incoming air volume into the furnace, thus you can control the temperature in the furnace at a given level!
Steel Wirbel Warm Boiler
An important indicator is the ratio of the capacity of the boot chamber to the boiler power. Striving easier - how many times during the day you have to approach the boiler to load fuel. In steel boilers, this figure is usually higher - an average of 1.5-2.5 liters / kW versus 1.1-1.4 l / kW in cast iron - therefore, the download is carried out less often.
Be sure to make sure that the emergency cooling system and specify the principle of its operation. This system may be needed in the event of overheating of the boiler and boiling water in the heat exchanger. Safer are boilers with a separate circuit of emergency cooling, if emergency cooling is arranged due to a sharp drain of water from the heat exchanger with replacing it on cold water, Make sure the boiler racks to the thermal impact.
Burn protection - an important indicatorEspecially if access to unauthorized people or children is open to the boiler room. The useful option is heat-insulated furnace knobs, protective covers and lattices, thermal insulation of the most heating planes of the boiler.
Thermal protection of boilers - a prerequisite security condition
Efficient and safe work of the wood boiler is impossible without proper Installation. KKAC Install the boiler with your own hands without violating the safety rules?
Any wood boiler in operation consumes quite a large amount of air, so for small power boilers, which can be installed in the general premises of the house, perform supply-exhaust ventilation, And with the boiler power, more than 50 kW is required to arrange a separate boiler room with a useful amount of room from 8 cubic meters. Wood boilers are installed on a solid, even base with a non-splashing coating - concrete, tile, porcelain stoneware. Walls should also be lined with non-flammable materials. The boiler room is equipped with forced ventilation.
Chimney for wood boiler is performed from stainless steel, ceramics or thick-walled metal pipe. The optimal choice is chimneys from stainless steel type "Sandwich". They are easily going from various elements - pipes fastened by clamps, roofing passages, unloading platforms. In the bends of such a chimney, we use taps at a certain angle. It is allowed to remove the chimney of the boiler not through the roof, but through the wall of the building. The height of the straight part of the chimney for stable thrust in the boiler should be at least 6 meters for a 16 kW boiler and at least 10 meters for a 32 kW boiler, with a pipe diameter 200 mm.
It is also necessary to clarify the terms of service and warranty service of the selected model of the boiler, the proximity of service centers and the ability to call specialists for installation and repair. It may happen that the service of a cheaper model will cost much more expensive than the analogues of famous firms having service centres In large cities.
Wood boilers for home heating after installation are joined to the water heating system. For uninterrupted operation of the system, you can additionally install a tank heater on electrical tanks in it, in this case you do not have to throw firewood during a night rest or abolisse from home.
Solid fuel boilers are indispensable for heating a private house in the absence of a gas pipeline or connecting to the central heating system. Their benefits are reliability and durability, simplicity. Many models are characterized by independence from electricity supply.
To take the right decision and purchase necessary equipmentIt is necessary to compare the characteristics of these structures.

Buying heating equipment is important and responsible. There are a lot of proposals on the market, but some one model cannot be recognized. The choice is determined primarily by those tasks, the execution of which is important to the consumer.
What kind of boiler did you like?
After the construction of the capital structure and arrangement of its water supply, next construction work is the organization of heating.
System heating inner space Houses, called heating, and consists of a boiler and radiating heat elements.
The choice of energy carrier (, coal, firewood,) determines the appearance of the boiler required for the operation of heating. The universal kind of heating equipment represent boilers that combine the possibility of working on several types of fuel.
The most common heaters of this type are combined gas-firewood boilers.
Heating boilers Gas firewood combine the possibility of working on two types of fuel: natural gas and (wood).
Each of the types of energy carrier has its advantages that determine its choice in certain working conditions.
Wood furnace makes it possible to organize heating systemnot dependent on the availability of the central supply and cost of the energy carrier (as it happens with the gas).
The gas furnace, in turn, allows to exploit the heating system without daily time spending and physical carrying efforts, laying them into the furnace, ignition and the simplicity of the room. This fact explains the widespread distribution of gas heating in the private sector, gasket gaskets and the installation of gas equipment in residential buildings.
House equipped only gas species Heating depends on the availability of a resource in the gas network, from its quality, composition, pressure inside the pipeline. The economic efficiency of gas heating is determined by the energy carrier price, which is not able to control the owners of the house. Rather, they have to be taken on fact, raising the price of payment for heat in their own home.
The desire to save and (available) leads to translation gas boiler In economical maintenance mode, when a small water heating temperature is maintained.
The main heating of the house in the evening is shifted to the wood-burning furnace.
After installing gas equipment in many houses, coal-wood furnaces were dismantled, and the new construction of a solid fuel furnace requires investing funds and professional skills. Therefore, a combination design was a popular type of heating of the gasified house, gas-wood-wood boilers.
As arguments for using combined boilers, factors make an attractive acquisition of a universal type of equipment are served.
Ability to reduce heating costs (If you use less expensive firewood instead of expensive gas).
It is possible to ensure yourself with wood fuel and independently, armed with a chainsaw and leaving the city in search of dry trees.
Semiautomaticization of the process. Automatic work B. gas mode Allows you to wake up in a warm room in the morning, and in the evening come home to the drowning residential space.
Modern design and possibility of transportation. In contrast to capital brick stoves Metal boiler (if necessary) can be dismantled, rearranged in a nearby angle or other room.
Gas-firewood heating boilers allow you to use one heating boiler for two types of fuel.
As a rule, the gas source is consumed at the time of the day when the automatic operation of the heating system is needed: at night, when everyone is sleeping, during the day, when family representatives disagree or study. Wood heating It works mostly in the evening and on weekends.
Most often in combined heating boilers, warming up solid fuel (Firewood) and subsequent mode of maintenance of temperature on gas. The design of such boilers is equipped with only one combustion chamber, in which different fuel can be burned.
Combined boilers Gas - solid fuel With two combustion chambers, a complex consisting of two furnaces represent.
Such a boiler is more expensive in manufacturing and selling, but at the same time it guarantees the reliability of the heating system, operating the main and reserve fuel type. In the design of such boilers there is a combustion chamber for solid fuel and gas burners.
For boilers, gas firewood is characterized by large sizes.
Boilers heating combined Gas. Firewood B. heating system need not only the heating function, their design should guarantee others performance features, namely:
In various designs, the listed requirements are satisfied to a greater or lesser extent. For example, no electricity dependence is provided in all boilers.
Often, an exhaust electric fan is installed in gas equipment, which provides complete removal of combustion products from the combustion zone.
In high-quality boilers, the automatic elements are duplicated by manual control elements (the fan is a manual damper) that allow you to operate the device in the absence of electricity.
The power of the combined boiler is determined by the size of the heated area.
For the estimated calculation of the required amount of heat, it is considered that in the harsh winter for heating 5 m 2 it is necessary to 1kW heat. The number of kW, which can produce a working design, is indicated in a technical passport. Various designs Boilers give out from 5 to 40 kW of heat per hour.
Gas firewood boilers represent combination structures that allow for heating both solid and gaseous fuel.
The demand for these structures is formed by a combination of their characteristics, the ability to reduce heating costs, is guaranteed to ensure its home energy and not to spend all the free time for servicing the heating system.
The cheapest view of the heating of a private house is one of which are firewood. From how high-quality and appropriate, it is for your conditions, the boiler you install, peace of mind and comfort will depend on the house. Therefore, what a solid fuel boiler is better for your home and for what criteria to choose to choose it is meticulously and thoroughly.
If you are going to buy a boiler for the heating of a private house, the first thing you need to know is the area of \u200b\u200bheated room. After all, the power of the unit directly depends on this. According to manufacturers, the calculation is simple: every 10 m2 of the area requires the production of 1 kW of thermal energy. With the total area of \u200b\u200bthe house 150 m2, it is quite power of 15kW. But here is not so simple.
The amendments must be done if:
It should also be remembered that in the harsh climatic zones in the cold season, the boiler will have to drown constantly, even at night. Therefore, it is better to choose an aggregate with a power reserve of 5-10 kW, which will control the intensity of burning.
In addition to power, the following characteristics are important:
There are several classes of boiler equipment on the principle of its action:
Classic.
Quite traditionally arranged. Consist of combustion chambers and an ash chamber, a water shirt tank, chimney. All the well-known types of solid fuel are going to work - firewood, ophil, pellets, and they can also be dried by coal. Used in heating circuits with natural air circulation. Every 5-7 hours of operation, you must load the next portion of the fuel. Automatic control unit adjusts the air supply to control the combustion process of fuel depending on the displayed temperature mode. In the best models in the chimney, the thrust regulator is built into the task of which togeting cold air inside the chimney in order to preserve the heat inside the furnace.
Gas generating or pyrolysis.
Such boilers have two combustion chambers. Firewood is laid in the lower furnace, where under the influence of high temperature and with the complete absence of oxygen, the process is carried out. Carbon dioxide enters the upper chamber, burns there, the heat exchanger is heated. Download fuel is necessary once a day. There are models of boilers with automatic and manual traction control. Watch user feedback on the forums, think more convenient for you.
Pellette
Why pellet boilers are so popular in Europe? It is this equipment that requires the minimum presence of a person and works on eco-friendly fuel. Pellets are granules produced from sawdust, peat, wood and agricultural waste.
From the disadvantages, we note the greater cost of equipment and pellets.
Please note: if necessary, the granular burner is covered on top of the iron sheet and you can heat the system with coal or peat, firewood is also suitable.
Long burning.
Closer than these boilers to pyrolysis, but the principle of operation is slightly different. The furnace consists of two chambers, below the flow and formation of gases. In the upper chamber, the gas is mixed with air and completely burns. According to the number of actions performed by gases in the heat pipes, are divided into one-, two- and three-way. The most effective are three-way heat generators, because they are mostly chosen as much as possible. thermal energy flue gases. On one loading of firewood works about two days, coal - up to five. In addition, it can be dried with coke, pellets and petroleum products. An ideal solution for non-residential premises, cottages, garages.
In the instructions for the equipment, boiler manufacturers describe in detail how the fuel will be used as the main one and which is optional.
Production Material: Steel Against Castle
The main materials for the production of solid fuel boilers are cast iron and steel. Steel models Have greater thermal conductivity and strong enough, and cast-iron brands with their fragility have a long (up to 20 years) service life. When studying consumer reviews, the following resumes turned out.
Steel boilers
Cast iron models
aVAILABLE "Dry Rust" film, it does not progress in contrast to corrosion).
The main concepts were dealt with, it was time to voiced additional criteria that would help to evaluate the convenience of using the models who are interested in you will add individuality to them.
The presence of outdoor insulation.
It is the external thermal insulation that reduces heat loss when heating the boiler room, the cooling of the boiler is noticeably slows down. It also allows you to load the furnace not earlier than 7-12 hours, there is no need for a "cold" extract.
The number of knees in the smoke system.
If the straight boiler, its performance is equal to the efficiency of a small room fireplace. Especially economical becomes heating deviceThe chimney is composed of the larger number of parts.
Superior system.
The presence of such a node reduces the requirements for the amount of knees of chimney. At the same time, the High efficiency boiler is perfectly coping with the process, even with a clearly weak pull.
The instructions with the design of the supervision require constant control of the furnaces of the furnaces of the furnace, the presence of the most imperceptible gap guarantees smoke from entering residential buildings at home.
Non-volatility
How the ability to work in the absence of electricity. In this mode, boilers are functioning having a natural circulation of the coolant. However, such equipment has a low utility coefficient, does not track the combustion process, in contrast to aggregates with an energy-dependent automatic control panel.
Temperature regulator.
In the absence of a thermostatic assembly, the system will have to look at. If there is a modern thermostatic device of one boot of the fuel chamber at a temperature near 0 ° C, it is enough for a day.
The presence of the combustion chamber of exhaust gases with a lining.
If you compare boilers with a lining function and without it, it turns out that the first is burned by 25-45% less than fuel at an equal output power.
If a solid fuel boiler you install in order to save, the lining function is mandatory.
Boiler equipment security system
There are consumer reviews on the cases of folding the walls of the boilers inside. Such a situation arises in cases of overheating due to disorders of operating conditions. Therefore, take care of your boiler and think over the security system.
Regardless of what to heat the boiler - coal or wood circulation of the heat agent is forcibly performed. In order for the circulation violation, there was no overheating to establish a cooling heat exchanger. It is embedded in the boiler, or installed at the output.
Inside the cast iron boilers, it is impossible to supply an independent cooling circuit, so it is mounted at the outlet from the device and is supplied with a thermoclap that is triggered when the critical temperature is reached.Some boiler manufacturers use valves-cut-off valves that block the fuel supply during overheating.
To feel 100% confident in safe operation boiler room, mount the tank battery in the heating system. It will accumulate heat, if necessary, transmit it to heating appliances. Such a buffer capacity will increase the efficiency of the boiler, will provide automatic maintenance of a smooth coolant temperature, reduce the cost of fuel.
Contrary to emerging opinion, it makes the walls of the boiler at all over the excessive pressure formed in the hydraulic bag, it is just produced through a subversive valve. Foldhes the walls of the boiler The physical ability of the metal to expand, while the process occurs in the easiest direction, inside. Remember - Normal pressure for a long-term combustion boiler 1.5 barrel, and the maximum allowable temperature of the coolant + 95 ° C.Choosing a solid fuel boiler, examine its functionality. Now the owners of private houses are concerned about finding a universal unit. Manufacturers expand Product Opportunities: offer models running on different types Fuel, automatically automate the process.

Buy equipment for heating follows after careful study technical characteristics Instruments, reviews on forums from real consumers, analyzing your own needs. Only the correctly selected unit will help create a comfortable atmosphere at home and fill it with cozy warmth.
The work of a wood boiler on gas fuel (natural gas) worries folk craftsmen. The combination of wood and natural gas adds comfort and economy of heating systems. I will say right away - the question of the translation of the wood boiler on gas fuel is not disclosed in this article due to its harmfulness and danger. But, combine firewood and gas - you can and need. This is really comfortable and economical.
Technically (correctly and safely) to improve the wood heating unit to the state of "omnivities" (gas and firewood) - it is impossible. Gas is an explosive poisonous fuel, a free circuit with which leads to sad consequences. You can not ignore the rules of operation of gas equipment.
Fantasies of folk craftsmen for gas heating are limited to the word "prohibited". Lawmakers, manufacturers, projectors and operationers are all reinsured on security. To climb through the official gas "forbidden" - almost unreal.
Officially, to transfer a wood boiler to gas fuel - a project that has been consistent with the relevant local control services - gas, fire, communal, etc. is required. Mounting with the subsequent introduction of heating equipment into operation, occurs according to current legislation. Per simple words Little engineering and technical problem lies.
Already at the initial stage of the translation of the wood boiler for gas fuel, the whole idea is divided into non-compliance of the combustion chambers and ventilation systems of wood and gas heating equipment. Wood and gas fuel is located in different aggregate states, it has a variety of specific callerness, so it requires completely different combustion chamber ventilation modes and, most importantly, various sizes of this camera itself.
A gas boiler - complicated product. The body of the gas boiler is calculated and is tested for years. Its dimensions are determined by the established norms and rules of combustion of gas fuel. Height, width, relief of the torch to the feed and to the arch, the tightness of the combustion chamber, the turbulization of gas flows, the quality of ventilation, the coordination of the operation of automation nodes, etc. - All parameters are verified by the manufacturer who is fully responsible for the safety of his brainchild. Gas boilers are not so much firms.
Wood boilers "rivet" all who are not too lazy. No responsibility. If only the warming-burning wood fuel. Unlike the gas, the design of the wood boiler is not limited to anything, except for one - the desire to "squeeze" from firewood heat. The housing of the wood boiler has additional devices, creating turbulence and slowing the speed of gaseous combustion products. Simply put, in the woodcut boiler there is a braking of gas streams, in order to increase the efficiency of the wood boiler as a whole. What, in relation to the rules of operation of gas heating equipment - Strumbering is prohibited! Everything gas boilers Work only on a straight line! Any fixtures that hinder the ventilation speed of the furnace (combustion chamber) of the gas boiler are prohibited. Any tubular heat exchangers, turbulizers, dampers, additional ventilation "pockets" and other - is prohibited for gas heating equipment.
Now let's try to mentally stick a gas burner in the wood boiler and remember that the wood-burning boiler is much larger from the wood boiler, because it is focused on firewood. That this will give in combination in not enough effective ventilation? Right. Excess combustion products in the boiler housing. And if you add a loading door and other holes, through which this excess of combustion products can enter the heated room (flopping), it becomes completely clear why no controller will give permission to operate such a monster.
P.S. There is a lot of things that makes the translation of a wood boiler on gas extremely unprofitable occupation. But, most importantly is the unjustified risk of operation of the converted heating unit. At the official level - the translation of the wood fuel boiler will never be encouraged. Heat engineers, officially - do not rewind wood boilers for gas burners. Because they know - all fiscal services (firefighters, gas, and communal) - will always fight with modified and self-made gas heating equipment.
As for the self-employment and independent (illegal) translation of the wood boiler on gas fuel - then everything will be offended from such "Kulibin". Man trying to independently translate wood boiler, stove or stove on gas heating - violates the whole bunch of laws and exposes its security and safety of the people around him unjustified risk.
From the point of view of the development of modern technology - the combined boilers "GAZ-DROVA" have the right to life. Combined boilers "GAZ-DRAVO" existed in the "Union". But, the Soviet combined gas-wood boilers always worked on separate nutrition - either gas or firewood (solid fuel). And, so that, and the other immediately, this is an obvious know-how. In the modern electronic world it is not difficult to realize any technical idea. Here, only - the benefit is small. The performance of modern amators, combined boilers "Gas Firewood" - or not safe, or too expensive, or uncomfortable and cumbersome in excision.
The combination of two separate boilers "Gas" and "Firewood" in one heating system - optimal option. If the boilers cost in different fire packages, then it is generally perfect.
