To control the return temperature of the boiler circuit, it is recommended to use a thermostatic mixing valve, which maintains the set return temperature of 50-55ºС.

Solid fuel boilers of long burning from the manufacturer

On our site you can find out what is solid fuel boilers where you can buy them, how to choose high-quality appliances, find out what the price of such boilers is. These are steel or cast iron heating appliances that run on solid fuels. If we are talking about a household unit, manual fuel supply is assumed, industrial designs are equipped with automatic supply and ash removal. Such boilers are installed where there is no gas heating, or as a backup means of heating.

Types of equipment

According to the type of control, boilers are divided into automatic and mechanical. Moreover, the second option compares favorably in terms of price and reliability. As a rule, such devices can be bought inexpensively. Boilers for heating need regular maintenance, such as descaling and burning, as this will help to avoid disruption of heat transfer from the boiler wall and damage to metal parts due to overheating. Modern solid fuel boilers are high-tech and safe, and their operation is stable. For advice on the choice of such equipment, you can contact our experts. Fuel for appliances such as solid fuel boilers long burning, serve:

. coal;
. firewood;
. peat;
. pellets;
. reed or straw.

Different types of fuel differ in burning time, which ranges from two to eight hours. Through the fuel exchanger, the heat released during combustion is transferred to water - the heat carrier of the heating system. As for long-burning boilers, such systems differ from conventional ones in their design. Here the combustion process does not start from below, but from above. The fuel ignited in this way burns much longer. The air distributor of such boilers has a telescopic design and constantly presses on the flame center under the action of its own gravity. And thanks to this pressure, the fuel burns out gradually in horizontal layers. It is this design that makes combustion better and longer, which is very beneficial for heating. Additionally, such units have a longer service life, because steel heat exchanger does not experience significant stress. Improvements in heating boilers, which have become more and more popular in recent times, due to the popularization of such systems, cause excessive pressure in the system and an increase in temperature. For this reason, they are dangerous, as they lead to ruptures in the heat exchanger tubes. To avoid such consequences, an expander tank is installed. It collects excess water, which expands when heated too much.

How to buy a unit

If you need to purchase a solid fuel boiler for long burning inexpensively in Moscow, we will be happy to help you in this matter. Here you will find many options for boilers from the manufacturer, you can order Russian-made goods wholesale or retail. Our experts will help you easily make the right choice and a profitable purchase.

Double-circuit solid fuel boiler

The double-circuit type of long-burning boilers for heating has design features. Two cylindrical containers, one placed inside the other, provide heating. The smaller capacity is responsible for the heating of the room itself, and the larger one supplies hot water. The scheme of a double-circuit boiler necessarily includes an air heating chamber, a heating system draft regulator, a telescopic pipe, a damper, a fuel complete combustion chamber, a generation and combustion zone, and an air distributor. The module is designed for thirty kilograms of fuel, which will burn for seven to eight hours, and the device will not need human intervention, it will work automatically.

Equipment Features

The double-circuit solid fuel boiler has certain pros and cons, which we will acquaint you with. Advantages: service life, efficiency, wide range, reliability, the possibility of autonomous operation. Suitable for a variety of different types inexpensive fuel. Disadvantages: fuel must be dry, lack of controllability hot water, lack of automatic control, manual filling. There are also features of the installation of such boilers. It should be handled only by competent and experienced professionals, which you can find on this site. They provide guaranteed high quality installation work. As a material for boilers for heating use:

1. Cast iron.
2. Steel.

The first option is more durable, provides better heat transfer to the room, but cast iron is more brittle. Steel boilers differ significantly in both quality and design. They are stronger but prone to rust. Manual and better assembly is typical for cast iron. But steel samples are easier to clean. If you are choosing which double-circuit heating module you should buy, you will be interested in what is the price of cast iron and steel modules. With this question, you can contact our staff, and they will be happy to advise you.

Boiler solid fuel long burning with a water circuit

The advantages of having a water circuit in a long-burning heating system include, first of all, performance, decent efficiency, quick heating of the coolant, rationality of heat distribution, and economy. But remember that if we choose a cast iron apparatus, its maintenance will still be quite complicated. A solid fuel boiler with a water circuit is quite inexpensive compared to other units. The requirements for documents for the installation of such heating systems are also low. To install a solid fuel boiler with a water circuit for your home, you will only need proper ventilation and a chimney in the room where this equipment will be installed.

Installation of a solid fuel boiler

Installation of heating boilers plays no less important role for the safety and reliability of the system than the devices themselves. Therefore, only real experienced professionals should be engaged in such work. Solid fuel heating boilers, as a rule, do not have controls and a circulation pump in their equipment. They also lack a security group. The boiler piping scheme is chosen in such a way as to solve these problems. To do this, the scheme includes additional equipment, devices and nodes. For example, a heat accumulator and a boiler indirect heating. These additions are needed to ensure uninterrupted and high-quality operation of the heating system. Here is how a solid fuel boiler is usually installed:

1. First of all, before installation, the power of the solid fuel boiler is determined.
2. Stands out for him separate room where all safety rules are followed. The floors of this place are concreted.
3. The installation of the apparatus itself and other components, such as regulators, chimney and other system components.
4. Setting the heating boiler.
5. Regular work on the control and cleaning of equipment.

Double-circuit boilers are usually installed in small buildings, for example, in wooden house where there is one bath near the kitchen. Then the boiler can be located not only in a separate place, but also in the kitchen.

Solid fuel boiler piping

The piping is a set of equipment included in the heating system. The binding must include:

. heating boiler;
. pipeline;
. warm floor, batteries;
. fittings;
. control equipment;
. control equipment.

Tying a solid fuel boiler is the work of a real installation master, because all future operation of the system depends on it. On our website, you can easily find such specialists in Moscow who take a responsible approach to the creation of heating systems. Here are the basic rules that must be observed in such a matter as piping a heating boiler:

1. It is desirable to have control devices.
2. The difference in temperatures of liquids during circulation should not exceed twenty degrees.
3. The pressure must be within the range of the relevant regulations.

The options for piping schemes are divided into schemes with natural circulation (open and closed), a collector connection scheme, with forced circulation, a hydraulic arrow, a heat accumulator and an indirect water heater.

Wiring diagram

The connection of heating boilers, as well as their further work, depends on how professionally the wiring of pipes and heating radiators is done. Only a person can create an ideal heating system connection scheme, knowing the principles her work and having rich experience in such procedures.

Each of these modifications has both advantages and disadvantages. For example, electric domestic heating boilers are safe, low level noise and no exhaust gases. At the same time, they consume a lot of electricity, which leads to high heating costs. Gas and liquid fuel domestic heating boilers are also quite expensive to operate and maintain. In this regard, solid fuel equipment is gaining more and more popularity.

Solid fuel domestic heating boilers are among the most environmentally friendly and unpretentious. They can successfully work on coal, wood and other fossil fuels. The main advantages of such equipment are the low cost of heating, automatic temperature maintenance and ease of operation.

In addition, Vienybė solid fuel household heating boiler is also distinguished by long-term operation without refueling (up to 16 hours), a high degree of automation and an efficiency of up to 90%. The safety of operation of Vienybė equipment is ensured by the presence of a safety valve.

Installing a solid fuel boiler is one of the best, and sometimes the only possible variant heating houses located in areas without centralized gas supply. Alternative - electric heating, for example, cannot be used in country houses and cottages, since the power supply system available in horticultural societies is not designed for such a load. Such a solid fuel boiler is convenient and economical. Firewood, coal, wood waste, briquettes, pellets are suitable for him - everything that the owner of the house can and deems necessary to prepare.

Features of solid fuel boilers

The boiler body can be made of cast iron or steel. The advantages of steel boilers include their lower cost and lighter weight, as well as better resistance to changes in body temperature. A significant drawback is a shorter service life. Sooner or later, the body of the high-temperature chamber burns out. The advantages of solid fuel boilers made of cast iron are strength and durability, the disadvantages are big weight and hypersensitivity to rapid temperature changes. If the temperature of the heat exchanger drops sharply even by 20°C, its sections may collapse. This feature should be taken into account in the process of designing the heating system.

An important factor is the presence or absence of an electronic combustion control system and forced pumping of the coolant. Boilers equipped with a control unit and an electric pump are more economical, but volatile. In the event of an emergency power outage, the electrified solid fuel boiler will be stopped. A simpler - non-volatile boiler does not need electricity. However, such units have a slightly lower efficiency, and in order to organize the movement of the coolant, they need a “gravity-flowing” system - a structure made of large-diameter pipes installed with a certain slope.

Pyrolysis boilers long burning

The most advanced, efficient and economical are solid fuel boilers with a stove, the design of which allows pyrolysis combustion of wood fuel - firewood, pellets, briquettes or woodworking waste. The only requirement for fuel is that its moisture content should not exceed 20%. Pyrolysis is a process of high-temperature decomposition of wood under conditions of limited oxygen supply, in which the feedstock is converted into wood gas, coal and resins.

Coal and resins smolder in the furnace, providing the temperature necessary to maintain the pyrolysis process (on average 400 ° C - 500 ° C), and the resulting wood gas is fed through a nozzle into a special high-temperature chamber, where it mixes with air and burns out with a large release of heat. The main advantages of pyrolysis boilers are unprecedentedly high efficiency and long-term fuel combustion, which provides the possibility of autonomous operation for 14 - 24 hours. The main disadvantage is the high price and dependence on the supply of electricity, since many models are equipped with automatic combustion control systems.

Pellet boilers

According to experts, one of the most significant drawbacks of most types of solid fuel boilers is the inability to maintain a constant combustion temperature in them. The use of coal and firewood of different quality and humidity does not allow stabilizing the heating temperature of the carrier, which negatively affects the efficiency of the heating system. Boilers, which are designed for the use of special granular fuel - pellets, are deprived of this drawback. Fuel for such boilers is made in Moscow from woodworking waste, peat and residues from the processing of certain types of agricultural products.

The feedstock for pellets is crushed, dried and compressed under high pressure into oblong granules. standard size. Stabilization of the combustion process and temperature conditions in pellet boilers is ensured by the automatic control of fuel supply from a special bunker. In the most advanced models, automation is able to clean the combustion chamber from soot and ash. Normalized fuel consumption allows you to accurately assess the need, and timely purchase the required amount of pellets. All pellet boilers are economical and have extremely high efficiency.

Many villages do not have a gas pipeline, and paying electricity bills can cost a pretty penny. Of course, this is annoying, but there will be no problems with heating even in this case. Using a solid fuel boiler will allow you to forget about the inconvenience associated with the cold, even if it is very cold outside.

Firewood - out of date?

Of course, in the age of ubiquitous automation, nanotechnology and amazing technology, it is hard to believe that the use of solid fuel for heating is advisable.

But just imagine, such a boiler is not just a “potbelly stove”, into which you need to constantly throw firewood. This is the real center of the heating system, efficient, economical, at the same time inexpensive and durable.

Principle of operation such equipment is extremely simple. As for different models of fuel, you can use shavings, briquettes, granules, even corn stalks and seed husks.

The design features of the firebox are such that not all firewood immediately begins to burn intensely, but only upper layer fuel. At the same time, its consumption is reduced significantly, which implies significant savings.

The water that circulates in the heating system enters the heat exchanger, which is heated by the energy of the burning wood. When the entire coolant warms up to the required temperature, the boiler turns off.

After connecting the unit to the water supply system and loading fuel, it can quite long time work without the user's attention. This time depends on both the quality of the fuel and its quantity. For example, briquettes, husks or spruce shavings burn out quickly enough, which means that it is often necessary to remove the ashes and load a new portion of fuel in order for the boiler to continue heating. Coal and anthracite burn longer, and often the energy they release during combustion is higher. This means that when working on this type of fuel, the boiler will heat up stronger and longer.

Fundamental differences

In order to make the choice of a boiler not difficult, we answered several popular questions that arise from buyers.

Are there any differences in the principle of operation and the fuel used?

Traditional devices work only on wood, coal or peat briquettes. They are completely independent of electricity, which makes them very popular with summer residents and owners of country houses. The only thing worth thinking about is the constant availability of fuel, that is, firewood, coke or coal. Such boilers perfectly maintain the set temperature, and for many years do not give any malfunctions.

Pyrolysis boilers can "boast" of very high efficiency. Their main difference from traditional ones is in the use of not only the heat from the combustion of fuel, but also the energy released by wood gas. Special fans heat the air in the combustion chamber to a very high temperatures, firewood begins to release gas, this process is called pyrolysis.

It is worth noting one more advantage of such devices - neither soot with soot nor ash is practically formed during operation.

In addition, there are also, which use special pellets as fuel - compressed wood. The advantage of such units is that they independently add pellets to the furnace using an auger.

Purchase long burning boilers , This perfect solution for heating large rooms, for example, private houses or roadside hotels. They can be universal (working on coal and wood), or wood. These units are very sensitive to the quality of the materials that the user sends to the combustion chamber. Therefore, we advise you to abandon damp firewood.

Manual or automatic fuel loading?

Wood chips, coal or peat will have to be thrown into the furnaces of traditional, pyrolysis boilers or long-burning apparatuses with one's own hands. At the same time, do not forget to periodically check the presence of fuel in the combustion chamber.

Automatic boilers , only calibrated charcoal is used as fuel, which is fed into the furnace, as in pellet boilers - using screws. Such a design will facilitate the maintenance of the boiler, but from time to time it is still worth “visiting” it.

Does the material from which the heat exchanger is made matter?

Getting more and more popular boilers made of steel . If your choice fell on a similar model, you can be sure that this equipment will last a very long time. Steel conducts heat well, in the event of a leak it is easy to solder it, carbon deposits practically do not form on it. But this material is not resistant to the formation of condensate, which means that corrosion is possible.

Cast iron boilers - a classic, but now they are gradually becoming a thing of the past. Despite the fact that the material from which the heat exchanger is made is an excellent conductor of heat and is almost 100% protected from rust formation, it has a number of disadvantages. Experts warn about the complexity of the implementation repair work- it is almost impossible to replace the cracked section due to the formed soot.

What is the best chimney design?

In fact, several factors influence how the ventilation pipes will pass. removing combustion products.

Firstly, thrust. In this case, this is an indicator of the speed at which smoke will be removed. If you notice that smoke accumulates in the room where the boiler is operating, you need to open the damper and, thereby, increase the air flow.

Secondly, chimney section. This parameter always depends on the design features of each boiler model. But, it is worth noting that a too narrow chimney may not be able to cope with the entire volume of combustion products, especially if the unit is powerful. And in too wide air will “walk”, without taking away unpleasant odors and fumes.

Speaking about design, it is worth saying right away that only specialists can do this, because knowledge of the aerodynamic features of the heating system, the boiler itself and the chimney is important. It can be square or round. But, keep in mind, the design should not have a very large number of bends, bumps and turns. By the way, draft is always better in round chimneys (since there are practically no barriers to air flow).

A solid fuel boiler is an ideal solution for heating a private house, especially if it is not possible to use gas or electricity. This equipment can heat a large volume of water in the heating system, so it will be warm even in a large room. Check how convenient it is to use economical inexpensive fuel, and feel the result of the boiler's operation in a few minutes after turning it on.

If we talk about modern heating devices and the principles of their operation, then one cannot fail to note such equipment as solid fuel boilers. As it becomes clear from their name, they function by using the energy of solid fuel. These innovative devices not only effectively heat the living space, but also fit perfectly into the interior and create comfort in any home.

However, not everyone can clearly say which solid fuel boiler is better. Therefore, it is necessary to determine how to choose a solid fuel boiler that best suits a particular room in terms of its performance and efficiency and is distinguished by reliability and long service life. This is what will be discussed next.

Types of fuel for boilers

One of the main criteria when choosing such equipment is, of course, the type of fuel used. In modern models, it is customary to use different sources energy, such as peat, pellets, briquettes, as well as the usual coal and firewood.

So, thanks to innovative production technologies, heat can be obtained from almost any source, thanks to which there is unique opportunity save a significant part of the financial resources and relieve yourself of the need for regular purchases of expensive fuel.

Mentioning the types of solid fuel boilers, special attention should be paid to the following devices:

samples functioning on coal. Not knowing how to choose a solid fuel boiler for a house located away from a large settlement, special attention should be paid to just such a mechanism. These boilers are perfect if there is no way to ensure proper storage of firewood. At the same time, the performance of such equipment will be very high, and its device will not become too expensive. The main advantages of a coal-fired boiler are versatility of use, low cost of consumables, as well as the ability to work autonomously;
pellet boilers and wood-fired boilers. The principle of operation of a solid fuel boiler of this type is based on the use of wood and pellets (special fuel pellets) as the main source of heat. The power of these mechanisms is quite high and can reach up to 200 kW, while they are economical in operation and can be installed in any room.

The availability of wood explains the wide popularity of these devices among the population. In addition, the efficiency of a solid fuel boiler operating on wood is high and reaches 90%. Wood and pellets burn for a long time without leaving behind any harmful products;
pyrolysis combustion boilers. The operation of these boilers is aimed at burning bio-based solid fuels, which can be wood pulp. These substances, when burned, emit a special combustible gas, due to which heat transfer is so efficient (the efficiency of pyrolysis boilers is from 85 to 92%).

In the event that the room equipped with the boiler is not equipped with access to the electrical network, then the most appropriate choice would be a solid fuel boiler operating offline, but with manual loading. This will allow you to adjust the operation of the device so that during its operation there will be no unforeseen problems.

Selection criteria for solid fuel boilers

Before deciding which solid fuel boiler to choose, it is necessary to take into account certain factors that greatly affect the choice of a particular sample.

The main criteria in this case are the following:

The area of a particular building. This parameter largely determines what power boiler should be purchased, and also affects the choice of fuel for it.
Height of floors in the living room.
Heat loss rate. This parameter is influenced, first of all, by the thickness of the walls and ceilings in the building, as well as the material from which the house is made. It would also be useful to take into account the area of door and window openings.
Climatic features of a particular region. As a rule, the main emphasis is on temperature indicators during the cold season, since it is these data that allow us to calculate the optimal heating power of the boiler.

It would be more correct to entrust such a calculation procedure to a professional specialist who is well versed in this equipment and is able to determine how all brands of solid fuel boilers should be calculated. In addition, qualified craftsmen always have various photo and video materials available to help during installation. However, this work can be done by an ordinary consumer.

To do this, you should consider, first of all, the footage of the house. For example, to provide full heating to a room of 100 m², you will need to use equipment with a capacity of 10 kW. In this case, you should always remember about a certain power reserve, which should be approximately 1 - 2 kW.

The difference between manual and automatic loading of boilers

When comparing solid fuel boilers, one cannot also miss such a parameter as the mechanism for loading them, which can be of two types: automatic and manual.

The design of boilers with automatic fuel supply is based on the main part and a special hopper, directly into which the fuel is placed. In the event that it is coal, then the size of its particles should not exceed 25 mm. However, there is also the possibility of using pellets that definitely do not exceed this parameter.

For continuous and high-quality functioning, one load of fuel is enough for about three to five days, which makes working with the boiler very convenient and easy.

At the same time, the size of the boiler hopper can be very different, it all depends solely on the preferences of the owners, since a lot of consumables can be loaded into this chamber, thereby forgetting for a long time about the need to replenish the supply of coolant in the boiler.

Fuel is supplied through one of two options - either using an auger or using a piston. Regardless of this, it can be said with confidence that the most economical solid fuel boiler will definitely have an automatic fuel supply mechanism, which will not only prevent excessive material consumption, but also be able to guarantee stable equipment operation.

These devices do not differ in cost-effectiveness, in addition, it is not recommended to mount them in residential premises, since their dimensions are very voluminous, which will be extremely inconvenient. It would be much more correct to install such equipment in an industrial type enterprise, since it is far from always possible in a standard building to provide a separate room for installing a solid fuel boiler.

What is the boiler heat exchanger

The most popular materials for the manufacture of such, of course, an important functional part of a solid fuel boiler as a heat exchanger are two - cast iron and steel.

It is on these devices that we should dwell in more detail:

Cast iron units are characterized by high performance if they run on coal fuel, since the use of firewood can adversely affect the power of the equipment.

The main advantages of products made of cast iron are their affordable price, the versatility of the fuel used for operation, as well as the ability to quickly and easily repair them for the entire system. However, such a technique also has disadvantages, the main of which are a small coefficient of efficiency (about 65 - 75%), the need for regular, as well as high rates of inertia.
In steel mechanisms, the main fuel is firewood or briquettes created by processing wood waste(read also: "").

The modern construction market offers a wide range of units with steel heat exchangers, which differ from each other, as a rule, in the following parameters:

the thickness of the metal used in the construction;
method of heat exchanger device;
productivity factor;
maximum operating time on one fuel load.

Such equipment is characterized by the fact that the period of operation on one load of fuel is from 4 to 8 hours, which makes it possible to avoid frequent replenishment of the boiler chamber with fuel.

Technical characteristics of solid fuel boilers

As a rule, in order to choose the best solid fuel boiler, you first need to familiarize yourself with the basic properties of this equipment.

The main technical parameters of such boilers are as follows:

type of fuel used for operation, which, as mentioned above, can be coal, firewood, peat briquettes, as well as recycled waste. Thanks to such a wide range of consumables, it becomes possible to significantly reduce the energy consumption required for heating;
combustion chamber capacity, affecting mainly the performance of the device and the number of fuel loads;
work automation. Many mechanisms are equipped with a similar function that helps to save yourself from constant control over the operation of the boiler system;
product safety performance. When choosing a particular unit, it is imperative to consider how safe its use will be. So, the main elements that any boiler should be equipped with are the automatic shutdown function, as well as the presence of an alarm;
energy consumption parameters. Some models are required to provide access to the mains, otherwise they will not be able to function. However, most solid fuel boilers are self-contained;
product price. When choosing such equipment, you should not focus only on low cost, since the technical characteristics of cheap equipment are usually far from ideal.

To decide which solid fuel boiler to choose, the video will help you:

Considering all these tips and recommendations, it will not be difficult to equip a solid fuel boiler in your own home, and if necessary, you can always seek help from qualified specialists who can provide photos of boiler samples and detailed videos, displaying the entire installation process.
