Heating boilers DON

Recommendations for use

For stable and high-quality operation of the system, the following several points must be taken into account:

1. The units must be used in open systems (with expansion tank). In addition, you should not allow the liquid in the tank to sink to the bottom.
2. If water hammers occur in the system (knocks are heard), you must immediately turn off the boiler, add liquid to the system and start the device again.
3. When the system is operating, it is necessary to monitor the heating of water; its maximum heating should be 95 °C.
4. Remember that when operating a solid fuel unit, it is prohibited to use only the water heater when the heating is turned off.
5. When in winter you need to stop the boiler for more than a day, then it is worth draining the liquid from the pipes to prevent failure of the system.
6. Before you start igniting the unit, you need to ventilate the combustion chamber for ten minutes.

If you are thinking about organizing a heating system in your home, but do not want to invest a lot of time, money and effort into boiler equipment, then you should consider the Don solid fuel boiler. This is a reliable and effective device that is popular among consumers and is gaining more and more positive reviews. Thanks to the large model range, you can choose the most suitable heating equipment option for you.

In order to supply heat to domestic and small industrial premises, Rostov has developed a universal boiler Don 16. The versatility of this brand of boiler lies in the fact that it can operate on both solid and gaseous fuels. For a better understanding, the characteristics of this boiler will be described in this article.

We provide installation and commissioning services for the products we sell.

The KST 16 boiler Mozyrselmash is one of the most popular products in its line. This model can also be slightly modified, namely, have a . This boiler has a rated thermal power of 16 kW. Very high efficiency guarantees economical solid fuel consumption and high productivity. Depending on the area of ​​the heated premises, a boiler of the required power is selected. Solid fuel heating boilers are perfect for remote houses and cottages where there is no gas supply

Typically, such boilers are installed in private homes and industrial premises, where it is very important to maintain the room temperature regardless of utilities. Unlike gas boilers, KST does not depend on gas pipes and electricity, which makes it as reliable as possible

The operational life of the KST boiler is at least 10-15 years, according to the manufacturer. The reliability and practicality of this boiler is confirmed by numerous reviews from satisfied customers. Purchase equipment only from official representatives of the Mozyrselmash manufacturer to protect yourself from low-quality products.

How to choose

Thermal power. When choosing it, you need to know not only the area that is supposed to be heated. If a device is selected for heating a private home, you must also take into account what material it is built from and how insulated it is.

In apartments, the location is important - central or corner. In the latter it is always colder, so the power must be chosen with a reserve.

The approximate power of the device is determined by the ratio - 1000 W for every 10 square meters of area. And for every cubic meter - 40–60 W. But it is recommended for cold houses and apartments to take boilers with a heating capacity reserve of 30%. Firstly, there will be no problems with heating in the most severe frosts, and secondly, the equipment will not wear out and will last longer.

Dependence on power grids. This parameter is more important for reliability and stability than for efficiency. If boilers require electricity consumption, for example for ignition, it is insignificant.

Number of circuits. The capabilities and cost of the heater depend on the choice of this parameter. Single-circuit ones are chosen for heating; double-circuit ones, in addition to heating rooms, can heat water for domestic use.

Installation method. Wall or floor. The choice depends on the area of ​​the room. Wall-mounted versions are more compact.

Heat exchanger material - steel or cast iron. Cast iron ones are more reliable, they are not afraid of corrosion.

Type of combustion chamber. It is more convenient with a closed firebox: they are safer, do not waste the internal air of the premises, they are preferred today by owners of houses and apartments that are not equipped with traditional chimneys.

How much do they cost

Equipment from domestic brands is a priori cheaper than imported ones, and products are no exception.

The price of Don boilers depends on the model and its power. An inexpensive single-circuit device KS-T-16, designed to heat 160 m², costs about 17,000 rubles. The cost of a powerful double-circuit device designed to heat 300 m² is 37,000 rubles.

Floor-mounted solid fuel boilers Don

The low price of Don floor-standing solid fuel boilers does not mean that these devices are of poor quality, as many of our compatriots are accustomed to thinking.

The thing is that the Don boiler is produced in the Russian Federation by Concord.

Therefore, the cost of production does not include the costs of delivery from abroad, import taxes and other duties that are imposed on foreign goods.

Don solid fuel boilers are produced with a power from 11 to 40 kW. All of them are universal and can work on wood, coal, briquettes and pellets. Does not depend on the power grid. They are marked with letters and numbers, for example, KS-T-1R or KS-T-11P, where:

• K – boiler;
• C – steel;
• T – solid fuel;
• numbers – rated thermal power;
• P – draft regulator;
• P – plate.

The efficiency of all units is 80%. A gas heater can be inserted into each boiler, then it can operate on natural or liquefied gas.

One of the most popular models is the Don 16 boiler with a gas burner. The technical characteristics of this unit allow it to be used for operation in open and closed heating systems (see Horizontal heating system: general information and recommendations).

The line also includes solid fuel heaters that can operate in automatic mode. Pellets are used as fuel. To automate the process, a pellet hopper is attached to the boiler. A pellet burner is inserted into the firebox. It operates from the mains, consumes 300 W when igniting, and 70 W/hour to maintain combustion. The burner weighs 18 kg.

From the hopper, pellets are fed through a pipe into the burner using an electric pump. All that is required of the homeowner is to replenish the pellets in the bunker, remove the ash once a week and clean the boiler several times a season.

Design features of solid fuel boilers Don

The Don heating boiler is made of steel. It has a built-in water circuit through which the coolant from the heating system circulates. The liquid is heated in a heat exchanger installed in the upper part of the firebox. The combustion chamber is quite large, it can accommodate logs up to 60 cm long. It is made of a special alloy that is not susceptible to corrosion.

The quality of Raden bimetallic radiators, according to reviews, is at a high level - you can safely buy them.

And domestic Monolit heating batteries are by far the strongest.

Smoke pipes pierce the heat exchanger so that the boiler can take maximum heat from the fuel and transfer it to the water. Thus, it was possible to use even the thermal energy of the exhaust gases. To make the heat removal process even more efficient, turbulators are installed in the smoke pipes.

In double-circuit boilers, the Don coil for the DHW system is located above the heat exchanger for heating. It is installed in such a way that there are smoke pipes inside the spiral. The water in such units heats up faster due to an increase in the heat removal area.

To produce biodiesel, you need plants: corn, rapeseed, etc.

A biofireplace installed at home has many advantages compared to a wood fireplace.

The boiler is equipped with a temperature sensor, thanks to which the degree of heating of the coolant is regulated. This happens automatically by increasing or decreasing the supply of secondary air. There are two doors on the front side of the heater: loading (fuel loading) and screwing (draft and secondary air control, ash removal).

Switching from solid fuel to gas

To convert a Don solid fuel boiler into a gas boiler, you need to purchase a special burner. It is connected to the electrical network and has an automatic system that regulates the degree of gas supply. In order to install the burner, you first need:

• remove the security door;
• dismantle the grates.

There are many benefits to switching to gas. There is no need to constantly add firewood. There is also no need for storage space for solid fuel. Those who use coal have another problem - where to put the sludge? With gas everything is much simpler. Even if you do not have a central gas pipeline, you can connect a cylinder or gas holder to the boiler.

In addition, there is no soot from the gas; it practically does not pollute the heat exchanger and chimney (see How to clean a chimney with your own hands). The temperature of the exhaust gases is also lower, which leads to the formation of condensation.

Therefore, the chimney must be properly insulated. On the Internet you can find both positive and negative reviews about Don boilers.

BOILERS DON KST 20 R

The solid fuel double-circuit heating boiler DON KS T 20 R (heating area up to 200 sq.m) is intended for heat supply to houses and buildings equipped with water heating systems with both natural and forced circulation of coolant.

The DON KS T 20 R boiler has a “water jacket” (water, which is the coolant, is distributed throughout the entire body of the boiler, and a special layer of thermal insulation (8 mm) retains heat as much as possible and leaves the surface of the boiler cool).

The DON KS T 20 R boiler has a large combustion chamber (it allows you to heat the room without refueling for at least 8 hours). It is equipped with a mechanical draft regulator. It is also possible to install a gas burner to operate on natural gas.

Design features and main characteristics

Like most solid fuel models, the Don 16 boiler is a steel device with a water jacket. Its main part is the firebox. Manufacturers deliberately increased its size so that it could hold more fuel, thereby ensuring longer combustion. The fuel chamber is made of a special alloy, which makes it resistant to corrosion.

Photo 1: Steel universal solid fuel boiler Don 16

The second significant part of the Don 16 hot water boiler is the heat exchanger. Its task is to ensure maximum heat removal and transfer it to the coolant. To ensure maximum heat removal, the heat exchanger is designed in such a way that smoke pipes pass through it. For even better heat transfer, turbolizers are installed inside them. The heated coolant is supplied to the heating system through the upper pipe. The water is returned to the solid fuel boiler through the return line pipe. The temperature of the coolant is controlled by a temperature sensor.

Photo 2: Ash pan of the Don 16 boiler of the old modification

In Don 16 double-circuit boilers, a coil is installed inside the heat exchanger around the smoke pipes. Due to its proximity to the heat source, the water in it quickly heats up, uninterruptedly providing the home owner with hot water for sanitary needs. The flow rate is controlled by a valve or mixer.

The front panel contains the screwing and loading doors. They serve for loading and removing ash, as well as cleaning internal surfaces. The draft, and therefore the combustion intensity, is adjusted using the damper handle.

Heating boilers DON

Description Universal boilers operate on solid (coal, firewood, peat briquettes), liquid (diesel fuel) and gaseous (low pressure natural gas) fuel. Many boiler models provide for operation on two types of fuel. For example, DON boilers are equipped with a chamber for burning solid fuel and have the ability to install mounted burners for gas. This is convenient in cases where you need to wait for gas to appear and until this moment you can use solid fuel. In addition, if you have gas, but there are problems with its supply, it’s a good idea to have other options in stock.

DON universal boilers are a combination of the best traditions of domestic heating equipment manufacturers. The unique technology, developed for real workers during the heyday of the engineering industries, has retained its main advantages to this day.

DON boilers are designed for heating houses with an area of ​​up to 500 m2, where it is possible to use both natural gas and solid fuel [wood, coal, peat] as fuel.

The power of such dual-fuel boilers can be from 10 kW to several thousand. True, universal boilers come only in floor-standing versions, unlike gas boilers, which can also be mounted. Universal boilers are designed for heat supply to individual houses, public buildings, equipped with water heating systems with natural or forced circulation of coolant.

The water jacket of DON boilers is designed in a unique way. Water, which is the coolant, is distributed almost throughout the entire boiler body. But a special layer of thermal insulation [8mm] allows you to preserve such valuable heat as much as possible and leaves the surface of the boiler cool.

The reliability and durability of DON heating boilers is ensured by 3 mm thick steel, from which almost the entire boiler body and combustion chamber are made.

DON boilers are the only boilers that, in the presence of a hot water supply circuit, have a replaceable copper coil. This is one of the most significant points. When working on hard water, which is especially typical for our country, the coil quickly becomes clogged. The ability to replace the coil significantly extends the service life of Don boilers.

If you have purchased a DON universal household boiler, then when you need to switch it from running on solid fuel to gas, you will not have to look for a compatible burner. Included with each DON heating boiler we already offer you a gas burner device. The large combustion chamber allows the DON boiler, when operating on solid fuel, to operate without refueling for 8 hours. You can do normal household chores during the day and sleep peacefully at night without worrying about the warmth of your home. DON gas boilers are equipped with high-quality automation to ensure convenient and stable temperature control in your home. DON universal boilers are powerful, reliable and durable. – meet all safety requirements of the State Standard of the Russian Federation.

How to disassemble a Don 16 boiler

When building a country house, owners are faced with the natural need to organize and equip autonomous heating.

When it is not possible to connect the house to gas supply, you have to choose something alternative. One of such heating system options is the Don solid fuel boiler.

It is worth recognizing that this is a convenient and reliable unit to use, which has many excellent reviews.

Let's start not with the question of where to buy Don, but with who produces it. The device is manufactured by the Conord Plant, located in Rostov-on-Don.

The instructions, uniform for current versions, allow them to be fueled with wood, peat and coal, and if the necessary substances are not available, the boiler can be freely switched to gas.

This remarkable flexibility of application is the result of the introduction of strict standards specifically created for the production of equipment with special consumer parameters. Don solid fuel boilers are produced with a power from 11 to 40 kW.

Specifications ↑

These products of the Rostov association are presented in five varieties. Without a pre-installed gas burner, only Don KS-T-16 boilers are available, which take only firewood. The remaining solutions (T-R, TG, TVm, TGVm) are equipped with the circuits necessary for the transition. General properties:

• power (kW): 16;
• Efficiency on solid fuel/gas (%): 75/82;
• gas consumption (m3/h): 2;
• weight (kg): 139-154;
• length/width/height (mm): 700/470/1030;
• heated area (m2): 160.

Only one unit in the line is equipped with a traction regulator, which makes operation easier. In improved solutions, the shortcomings associated with its absence are compensated by the decent adaptability of gas burner systems and the good performance of the DHW circuit. The modest design of the classic version is explained by the desire to ensure ease of use.

Operating principle ↑

The functioning scheme is simple. The elements that make up a regular Don 16 boiler are few, they are simple: a firebox with a water jacket, temperature sensors, a pipe system supplemented with turbulators.

When burning fuel, the water cavity heats the injected water, convection amplifiers send the liquid into the general circuit through the upper pipe, and it is replaced by cold flows supplied to the lower one.

The meter monitors and corrects the temperature.

Although the devices are manufactured on the same base, they have slightly different structures. The difference is in the details. The letters that make up the brand name will help you figure out what advantages they offer in each case.

There are nine letter designations: 1). "K" - boiler. 2). "T" - solid fuel. 3). "G" - gas. 4). "M" - modified. 5). “C” - with a steel heat exchanger. 6). “C” - with cast iron. 7). “B” - with a water coil. 8).

“P” - with draft regulator.

9). "TG" - universal.

Advantages and disadvantages ↑

Steel heating boilers "DON" are designed for heating premises with an area of ​​up to 400-500 sq.m.

Consumers appreciate the compliance of the equipment with domestic conditions of use (severe and long frosts, hard water), and the energy independence of its mechanisms. Previously, consumer interest was aroused by the good technical characteristics of the lines; now the stability of demand is supported by such qualities as:

• excellent thermal insulation and high safety (provided by an 8 mm casing);
• an impressive period of independent combustion with low fuel consumption (the presence of a lined chamber makes the Don 16 boiler capable of operating on one load for up to 8 hours);
• durability (due to the case being made of 3 mm steel);
• maintainability (parts can be replaced).

Lining critical bunkers prolongs thermal processes, increases efficiency, thereby guaranteeing decent efficiency. It also, as reviews indicate, leads to a decrease in ease of use. Additional processing of sections increases:

• heaviness (the Don 16 boiler is prohibited from being hung or placed on thin supports; it should be placed on thick floors or platforms);
• demands on fuel (humidity up to 15%; if the standards are neglected, smoke and soot will appear);
• uncontrollability (difficult to accurately calculate the operating speed and set the heating temperature);
• capriciousness in installation, which is what owners most often complain about.

Installation and operation

Installation of solid fuel boilers does not require special permits. However, owners must ensure that the work is carried out in strict compliance with the requirements of building and fire safety regulations. Here are some useful tips:

• It is recommended to install the boiler on a flat concrete base, at least half a meter away from the wall;
• if the boiler is installed on a wooden floor, but under it and half a meter in front of its front wall, a sheet of asbestos cardboard or felt soaked in a clay solution is placed on the floor, on top of which a sheet of steel is placed;
• In order for water to circulate normally in the system, the boiler must be installed so that its lower pipe is located lower in level than the outlets from the heating radiators;
• connection to pipes can be made either by threads or by welds.

Particular attention should be paid to the chimney design:

• The chimney pipes are made double-circuit with heat-insulating material laid between them. This will prevent the formation of condensation;
• Asbestos-cement pipes are used to construct the chimney;
• the diameter of the chimney must be equal to the diameter of the boiler outlet pipe;
• the chimney must be installed above the roof level in accordance with the instructions of SNiP;
• The chimney pipe must be level and have no ledges.

Unit maintenance

In order for the system to work without failures, you need to follow a number of rules:

• boilers must be used in open systems (with an expansion tank). In this case, you need to ensure that the water in the expansion tank does not sink to the very bottom;
• if water hammers occur in the system (a knock is heard), you must immediately stop the boiler, add water to the system and start the unit again;
• when operating the system, you need to ensure that the water does not heat up to a temperature of more than 95 degrees;
• when using solid fuel boilers, it is prohibited to use only a water heater when the heating is turned off;
• if in winter it is necessary to stop heating the boiler for more than 24 hours, it will be necessary to drain the coolant from the pipes to prevent destruction of the system;
• Before you start igniting the boiler, you need to ventilate the firebox for 10 minutes.

So, if you need to organize heating in your house with minimal material costs, you should pay attention to the Don solid fuel boiler. This is a reliable and economical unit that has excellent reviews from consumers

A wide range of models will allow you to choose the best option for any home.

Installation and installation of the Don KST-16 boiler

___________________________________________________________________________

Installation work on solid fuel boilers Don KS-T-16

When installing on combustible building structures, 0.5 m below the unit and in front of its front, it is necessary to install a gasket made of steel sheet over asbestos cardboard or felt soaked in clay mortar.

In order to improve the conditions of water circulation in the heating system, the Don KST-16 boiler must be installed in such a way that its lower pipe is lower than the radiators of the heating system of the building (structure).

Pipelines are made from water pipes. Pipes can be connected using threaded fittings and/or welding.

When installing pipelines using welding, it is recommended to leave threaded connections to ensure disassembly of the system during repairs.

Recommended installation dimensions for radiators when installing residential heating:

- at least 3 cm from the radiator wall;

— from the floor to the bottom of the radiator – 10 cm;

- from the top of the radiator to the window sill - at least 10 cm.

— When installing a radiator in a niche, the distance from the radiator to the side wall of the niche is at least 10 cm on each side.

When bending pipes, it is necessary to observe a minimum radius, which must be at least 2 outer diameters of the pipe.

When laying pipes, risers must be installed strictly vertically. The permissible deviation from verticality is 3 mm over 3 meters of pipe length.

Horizontal pipelines must be laid with a slope to allow air to escape from the system. The slope must be at least 10 mm per 1 linear meter. pipeline.

In this case, the slopes of the branches to the heating device must have a slope of at least 10 mm along the entire length of the supply towards the heating device.

When installing 2 or more KST Don boilers on 1 system, it is necessary to install a plug valve or valve on the return line to each boiler.

The diameters of the heating system pipelines are selected using a special calculation.

In typical heating system designs, the most common values ​​are:

— main riser from the boiler — 1* — 2″

- distributing and collecting lines 1ј - 1Ѕ"

— connection of devices * — 1

The chimney structure must meet the following requirements:

— The chimney to which the KS-T-16 Don boiler is connected must be located in the internal main wall of the building.

— Smoke exhaust pipes laid through unheated rooms must, if necessary, be covered with thermal insulation.

— It is allowed to connect heating boilers to chimneys made of asbestos-cement pipes.

The cross-sectional area of ​​the chimney should not be equal to or less than the area of ​​the boiler pipe connected to the chimney.

Chimneys must be vertical, without ledges.

Cold running water is connected to the lower pipe of the water heater of the Don KS-T-16 boiler, and the hot water supply is connected to the upper pipe.

A safety valve adjusted to a pressure of 0.15 MPa must be installed on the supply line (no further than 500 mm from the upper branch pipe of the device).

If the heating system involves filling and feeding the boiler from the water supply network, it is necessary to install a check valve in front of the tap.

Fill the system with a pressure not exceeding the operating pressure of the unit. Fill the heating system with tap water.

Testing (pressure testing) of the heating system (pipes, radiators) should be carried out with the heating boiler disconnected, because the pressure in it should not exceed the working pressure specified in the passport.

The volume of the expansion tank depends on the volume of the heating system and is calculated when developing a heating project.

To prevent freezing of the expansion tank and drain pipe in winter, they must be installed in rooms with a temperature not lower than +5°C. There should be shut-off valves at the inlet and outlet of the coil.

Features of operation of the solid fuel model

The Don 16 solid fuel heating boiler also has its advantages. It will be cheaper to operate because it can work not only on coal and wood, but also on waste from the wood processing industry. The cost of pellets and briquettes today is much lower than that of energy resources, and in terms of basic indicators they are not inferior to them.

So it will be possible to combine different types of fuel depending on the weather outside and thereby win in monetary terms. But in order to use such a boiler, you will first need to build a high-quality chimney and separate part of the house for the boiler room so that garbage does not accumulate in living areas. If you take a long-burning model, you won’t have to add fuel too often.

There are also universal heating boilers Don KS TGVM 16, which can run on gas or solid fuel. This is the most optimal of all existing options. Heating a house with gas in cold weather is much more difficult than heating it with coal. So, with a slight minus, you can use a gas burner, and in case of cold weather, you can connect to heating using solid fuel.

The ability to choose will allow you to more flexibly calculate your budget for the heating season and not run the boiler in vain if you can maintain a comfortable temperature inside the living quarters and at a minimum operating mode.

Which Don boiler model should you prefer?

The line of autonomous heating systems of domestic production is represented quite widely on the domestic market. Of all the existing models, one of the most popular is the Don KS 16 boiler. This unit has excellent technical characteristics, is easy to use and consumes fuel quite economically.

The most important thing is that domestic assembly and components immediately prepare the equipment for work in harsh conditions. Many imported analogues do not last long precisely because they are developed taking into account European standards

In the Russian Federation, not a single communication system can boast of meeting the highest standards.

The product line of this model includes several varieties. The main classification is carried out depending on the type of fuel used in the work. There may also be variations in the number of working circuits and smaller differences. Basically, it is customary to classify the following boilers into a separate group:

• — gas boiler Don 16;
• — Don 16 solid fuel boiler.

Advantages of a gas boiler

Installing a turbocharged chimney will allow you to create a horizontal exhaust gas exhaust system. There is no need to allocate a special place for storing fuel, so the room will always be kept clean. Everyone knows how tightly coal dust eats into surfaces and how difficult it is to wash it off.

It is also important that a person will not have to deal with adding fuel, so you can forget about regularly monitoring the time so as not to miss the next session. The boiler is as ergonomic as possible and easy to use, and is also quite reliable if service inspection is carried out on time

• — the working chamber where fuel combustion occurs;
• — a heat exchanger in which the coolant receives thermal energy;
• - a chimney for releasing combustion products into the atmosphere.

You can familiarize yourself with the device in more detail using the instruction manual. Reviews of Don 16 heating boilers confirm their good reputation and high reliability indicators.

Features of operation and scope of application

When installing and operating boilers, you must strictly observe safety precautions

During operation, the water in the tank must not be allowed to evaporate to the very bottom. When starting, it is recommended that the filling rate be no more than 8 l/min; the energy carrier is supplied until water appears in the overflow tube on the expander. The automation is set to a maximum temperature of up to +95°C.

It is not permitted to use the connected boiler if the heating is switched off. In winter, the liquid from the circuits is drained if the unit remains idle for more than a day. The heater is placed below the boiler piping if the system is based on a gravity circuit.

The boiler power is selected 30% more than the calculated one if the unit will operate in harsh conditions of a poorly heated room or house without external insulation. When choosing, the device’s dependence on electricity is taken into account. If the model does not have electric ignition, you do not need to connect it to the network.

Features of operation

Each model is accompanied by instructions in which the user can familiarize themselves with the rules for operating the heater, its connection diagram, design features, settings and adjustments.

The system is filled gradually, at a rate of no more than 8 l/min. The water is fresh. Filling is continued until liquid appears in the overflow tube of the expansion tank.

Description of the ignition process:

• ventilate the combustion chamber for 5–10 minutes, the main valve must be closed;
• checking traction by bringing a paper strip closer to the viewing window;
• opening the air supply gate and igniting the flame;
• closing the door;
• temperature control by coil valve.

Installation and strapping

The installation of boilers should be carried out by specialists, but even users benefit from knowing the installation rules. If the piping is carried out according to the gravity scheme, the heater is placed lower than the return pipes - this improves the movement of the coolant. The chimney is located inside the structure.

If the chimney passes through unheated rooms, it must be insulated.

Connecting additional equipment

All products are easy to use, but it would be a good idea to equip the device with a thermostat - this device will make the equipment operate as efficiently as possible. You can also purchase an additional coil in advance in case of breakdown. As standard, the heaters are equipped with an adjustable front damper.

Boiler characteristics

With the help of Don brand heating equipment, you can heat a residential building or any other room as efficiently as possible, as well as ensure the supply of hot water. The equipment has many advantages, but it also has disadvantages.

Main advantages

Reading consumer reviews, we can highlight the main advantages of using these heating units:

Versatility. The unit can operate on almost any solid fuel - firewood, coal, peat briquettes, wood waste (shavings, pellets, etc.). Moreover, if necessary, you can install a gas burner.

• Energy independence. The boiler does not require a power connection, so it will function normally even during a power outage.
• Long service life. The combustion chamber material is high-strength steel with a high carbon content. The thickness of the steel sheets is 3 mm. This material is resistant to high temperatures and corrosion, while at the same time it has good thermal conductivity.
• Safety. The boiler body has good thermal insulation. On the one hand, this increases operating efficiency, as it significantly reduces heat loss. On the other hand, it eliminates heating of the outer surface. The boilers meet fire safety standards.

• Long intervals between fuel refills. Most models from the Don line of boilers have large-volume fireboxes. This allows you to increase the interval between fillings to 8 hours, which greatly facilitates boiler maintenance.
• Unpretentiousness to the quality of the coolant. The boiler can also operate when using hard water as a coolant.

• Discreet and attractive design. The external coating of the boiler is made of heat-resistant paint, which retains the attractive appearance of the boiler for a long time.
• Quality. The unit casing has no gaps, all parts fit perfectly together. The threaded connections are made impeccably, the joints are welded with high quality.

• Availability. The boiler itself has a relatively low price, and the fuel for it will also be inexpensive.
• Control. The presence of a built-in thermometer allows you to control the temperature in the system.

Flaws

The main disadvantage of all solid fuel boilers is the inability to fully automate the process. To ensure normal operation of the heating system, you will need to regularly add firewood to the firebox, as well as clean the equipment to remove combustion products.

Another significant drawback is that a solid fuel heating unit takes quite a long time to cool down. This disadvantage manifests itself when it is necessary to carry out urgent equipment repairs. After stopping the boiler, you will have to wait quite a long time for the parts to cool down and you can start working.
