Technical characteristics of Don boilers and their advantages in heating

Where to buy 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.

Recommendations for installation

Installation of solid fuel units does not require special permits. At the same time, this does not mean that the owner should not monitor the quality of construction work and comply with fire safety standards.

Expert advice:

1. The boiler should be installed on a flat concrete base, with a distance of at least 0.5 meters from the wall.
2. When installing the boiler on a wooden floor, 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 laid on the floor, and steel sheets are laid on top of it.
3. For normal fluid circulation in the system, the boiler must be installed in such a way that its lower pipe is at a lower level compared to the outlets from the heating batteries.
4. Connections to pipes can be made using both threads and welds.

Don’t forget about the features of installing chimney ducts:

• chimney pipes are double-circuit, with thermal insulation between the structures. Thus, no water vapor is formed;
• for the construction of a chimney, asbestos-cement pipes are often used;
• the diameter of the chimney pipe must be similar to the diameter of the outlet pipe of the boiler equipment;
• the chimney must be installed above the roof level, read the SNiP rules;
• the chimney pipe must be level, without ledges.

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.

Model overview

Let's describe the best models.

KS 16

Of all the models presented by domestic manufacturers, one of the most popular is the “Don” KS 16. Its main advantages: excellent technical characteristics, convenient operation and economical consumption of energy resources.

Having domestic assembly and components, it is ready to work in the most difficult climatic conditions. It is the Russian climate that does not allow many European analogues to compete with domestic developments. This line includes modifications that differ in the number of circuits and a number of smaller differences.

Key technical parameters:

KS-T-11

Steel. Non-volatile. For small objects. Operates on gas or solid fuel - the burner is changed.

Automation installed. Thanks to the Honeywell regulator, energy consumption is reduced by 30%. The firebox material is carbon steel, resistant to corrosion. Adapted to hard water.

• Floor installation.
• Steel heat exchanger.
• The exhaust of combustion products is a chimney.

"Don Eco"

An economical version, the main difference of which is its compactness. The small device contains reliable Italian automation and an efficient heat exchanger. It features stable burner operation and high heat transfer.

The boilers are designed for heating small areas; they can be used with a flow-type water heater (“DON” or “CONORD”). In tandem with a water heater, this model will provide a small home with heat and hot water.

As an example, here are the technical characteristics and design features of the Don Eco KS-G-12S:

• Heating system pressure (min/max) - 0.1/1.2 bar.
• The coolant is water.
• One circuit.
• Floor-standing version.
• Open firebox.

DonStail

New gas equipment from DonStail models with increased performance. Powerful heaters with a strict and stylish design. The white color and decorative perforations on the body create a feeling of lightness; the device fits harmoniously into a modern interior.

Thanks to the special design of the heat exchanger and Sit automation and Polidoro burner, these modifications have high efficiency, low energy consumption and are completely safe.

Characteristics of the single-circuit version of DonStail KS-G-12 S:

• Floor-standing version.
• Open firebox.
• Steel heat exchanger.
• White color.
• Warranty - 3 years.
• Piezo ignition.

• At 50 kW. Consumption 3 m³/h. Provides heat for cottages up to 50 m². Efficiency - 85%. Dimensions - 850x700x1430 mm.
• At 100 kW. The most powerful option is for 1000 m². Efficiency - 87%. Weight - 560 kg. Dimensions - 1280x900x1090 mm. An ideal solution for large country houses and non-residential premises.

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.

Firewood quality

The best firewood for a solid fuel boiler has always been oak firewood. Due to its high quality, these raw materials belong to the elite class. The cost of oak firewood is high, so it is not affordable for everyone. But such firewood is often indispensable when it comes to the taste of baked bread, pizza or other pastries. Here oak logs are simply irreplaceable.

Let's look at the characteristics of firewood from different types of wood:

• Oak: an elite, expensive variety. Burns powerfully, giving off a huge amount of heat;
• Birch: Best quality/cost ratio;
• Alder: excellent firewood, the house warms up quickly. In addition, the ancestors considered alder firewood to be “medicinal”, since in a house heated with its help, people were less likely to get colds;
• Pine: hot and aromatic firewood that burns well due to its resin content.

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.

Chimney connection

When connecting equipment to a chimney, it must be taken into account that the cross-section of the pipe should not be smaller than the connecting pipe. There should not be any leaks at the connection point, since carbon monoxide entering the room leads to poisoning. The pipe located on the street must be insulated and a canopy must be installed in the upper part.

Conclusion

I would like to note that the technical characteristics of the heat supply equipment in question, produced by the Condor Plant, have good performance, price and quality indicators. But, like all other equipment, even from foreign manufacturers, it has positive and negative sides. In the end, the decision is yours.

Reviews ↑

On a professional forum, the installer Melky writes that in the villages of his region they order only such solid fuel boilers, everyone is happy. In response, Lis criticizes the KS-T-16R model. He is angry that in winter he is on duty at the stove, adding firewood every 3 hours, struggling with the tricks of the traction regulator, suffering from the cold. Nikola SD gives him a hint: the problems are created by the ill-conceived operating principle, which requires igniting all the loaded fuel at once. The combustion is uneven; adjusting the damper does not help. It is especially difficult to achieve the required performance in the off-season. Serge Ch. says: having found himself in the described situation, he asked a specialist to find out its cause; It turned out that the problem was the short length (less than 3 m) and small (less than 150 mm) diameter of the smoke pipes. I ordered a rework, the price of the service seemed a bit high. In the discussion section of the website on energy saving, NVB praises the KS-TGVm-16 version for its ability to provide powerful coolant circulation, allowing one to avoid purchasing a pump. Master Hottabych assures: the devices will delight your grandchildren if you set the emergency valve to 1.5 atmospheres, add foreign automation, and spend money on decent fuel.

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.

Price ↑

Multi-fuel water heating systems are considered universal products. The cost of the units is: 4-7 thousand rubles. (budget options), 10-35 thousand rubles. (affordable), 35-70 thousand rubles. (premium). According to the specified gradation, Don 16 boilers belong to middle class products, which is confirmed by the following figures:

• models KS-T-16: 12-14.5 thousand rubles;
• version KS-T-16R: 15-16 thousand rubles;
• systems KS-TG-16: 16.5-17 thousand rubles.
• variations KS-TVm-16: 17.5-20.5 thousand rubles;
• TGVm-16 schemes: 21-23 thousand rubles.

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 made of and how insulated it is.

In apartments, the location is important - central or corner. It’s always colder in the latter, so the power needs to be chosen with 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.

Distinctive features of Don boilers

Electrically independent All Don boilers do not require electrical energy to operate. Unique water jacket 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 retain valuable heat and keeps the surface of the boiler cool. Safe A special layer of thermal insulation (8 mm) allows maximum preservation of valuable heat and prevents heating of the surface of the Don boiler. Reliable and durable DON boilers are reliable and durable, since the entire boiler body and combustion chamber are made of 3mm thick steel. Guarantees your peace of mind The large combustion chamber allows the Don boiler, when operating on solid fuel, to operate for up to 8 hours without refueling Single-circuit Don boilers (heating) KS-T-16, KS-TG-16 Double-circuit Don boilers (heating + hot water supply) KS-TGVm- 16, KS-TVm-16 Solid fuel boilers DON KS-T-16; KS-TVm-16 Universal (solid fuel and gas) boilers Don KS-TG-16; KSTGVm-16 Provides the ability to use both natural gas and solid fuel (wood, coal, solid fuel) as fuel. If you have purchased a DON universal boiler, you can easily convert a solid fuel boiler into a gas one without replacing the burner. Included with the DON universal boiler, we already offer you a gas burner device. Adapted to operating conditions on hard water, DON is a unique solid fuel boiler that, if there is a hot water supply circuit, has a replaceable coil. When working on hard water, which is especially typical for our country, the coil quickly becomes clogged. The ability to replace the coil significantly increases the service life of DON boilers.

When water from the plumbing system passes through it, the water in the coil heats up. Adjustment of the required water temperature is achieved with a mixer. In the absence of a mixer, adjusting the water temperature is achieved by increasing or decreasing the speed of water passing through the coil using a valve. 5.2.5.1 Construction of a natural gas boiler In a boiler for burning natural gas, instead of grates, a scramble door and a cast iron frame, a gas burner device with automation is mounted. On all boilers operating on natural gas, a combustion plate is installed in the upper part of the firebox close to the front wall. 5.2.5.2 The procedure and principle of operation of the gas burner device is described in the attached operating manual for the gas burner device. 6. INSTALLATION OF BOILER AND HEATING SYSTEM ATTENTION! Installation of a heating boiler should only be carried out by gas service specialists with a mark in the passport! 6.1 The gas burner device is stored in a separate package. To avoid damage, boilers must be transported in containers directly to the installation site. 6.2 When installing on combustible building structures, 0.5 m below the boiler and in front of its front, it is necessary to install a steel sheet gasket over asbestos cardboard or felt soaked in clay mortar. 6.3 In order to improve the conditions of water circulation in the heating system, the boiler must be installed in such a way that its lower pipe (see Fig. 1,3, item 9) is lower than the radiators of the heating system of the building (structure). 6.4 Pipelines are made from water pipes. Pipe connections can be made by threading and welding. 6.5 When installing pipelines by welding, threaded connections should be left to ensure disassembly of the system during repairs. 6.6 Recommended installation dimensions for radiators when installing residential heating: a) from the wall to the radiator no less than 3 cm; b) from the floor to the bottom of the radiator – 10 cm; c) from the top of the radiator to the window sill - at least 10 cm. d) When installing the radiator in a niche, the distance from the radiator to the side wall of the niche is at least 10 cm on each side. 6.7 When bending pipes, the radius must be at least 2 outer diameters of the pipe. 6.8 When laying pipes, risers must be installed plumb. The permissible deviation should not exceed 3 mm over 3 meters of pipe length. 6.9 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 line. meter of pipeline. In this case, the slopes of the branches to the heating device must be at least 10 mm over the entire length of the line towards the heating device. 6.10 If there are more than one boilers in the system, a plug valve or valve is installed on the return line to each boiler. 6.11 The boiler installation diagram is shown in the figures.

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 chimney installation must be agreed upon with the fire authorities. To ensure fire safety and avoid gas contamination in the room, the chimney must be installed above the roof level in accordance with the requirements of SNIP 2.04.08-87. 6.13 The cross-sectional area of ​​the chimney should not be less than the area of ​​the boiler pipe connected to the chimney (see Table No. 1). 6.14 Chimneys must be vertical, without ledges. 6.15 The diameters of the heating system pipelines are selected using a special calculation. The most common diameters are: - main boiler riser - 1¾-2ıı - distribution and collection lines - 1¼ - 1½ıı - connections to devices - ¾ - 1ıı 6.16 Heating boilers can be installed in a closed heating system with a membrane-type expansion tank. 6.17 When connecting the boiler coil to the hot water supply system, connect the cold water to the lower pipe, and the hot water outlet to the upper pipe. The pressure in the heating system in operating condition, at a water temperature in the heating system of 60º-80ºС, should not exceed the operating water pressure indicated in the table. 1 point 4 of the manual, that is, 0.12 MPa (1.2 kgf/cm2) or 0.2 MPa (2.0 kgf/cm2) for KSts boilers…. A safety valve should be installed on the riser, adjusted to a pressure of 0.15 MPa (1.5 ± kgf/cm2) or 0.18 MPa (1.8 kgf/cm2) for KSts boilers…. To control the pressure in the heating system, a pressure gauge with a measurement limit of 0-4 kgf/cm2 must be installed. ATTENTION: The design of a heating system with forced or natural circulation must be developed by a specialized organization that has the right to carry out this work. 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 boiler. 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 the boiler should not exceed the operating 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. Installation of the boiler and heating system must be carried out taking into account the technical data (Table 1) 7. REQUIREMENTS FOR INSTALLATION OF A NATURAL GAS BOILER 7.1 When operating on natural gas, the boiler is installed according to a design agreed with the city gas authority. The installation and installation of the boiler is carried out only by a specialized organization that has the right to carry out such work. 7.2 Installation and adjustment of the gas burner device is permitted to be carried out by employees of specialized organizations licensed by Gosgortekhnadzor, in accordance with the requirements of the gas burner device operating manual. 7.3 The Gorgaz representative, when accepting the heating installation, must instruct the consumer on the rules for using gas appliances. 7.4 Install the gas burner device in accordance with the burner operating instructions. 8. BOILER MAINTENANCE.

MAINTENANCE OF THE HEATING SYSTEM 9.1 When operating the system, the water level in the expansion tank should not fall to the bottom and it must be maintained by periodically adding water, reducing the temperature of the water in the water boiler jacket up to 70ºС. 9.2 ATTENTION! If there is a knock in the system (hydraulic shock due to steam formation), immediately stop burning in the furnace and allow the water to cool to a temperature of 70-750C, then replenish the system with water and light the boiler again. 9.3 In winter, if it is necessary to stop heating for more than a day, it is necessary, in order to avoid freezing, to completely empty the heating and hot water supply system of water. The heating system is released through water drain 8 (Fig. 13) and water drain 7 (Fig. 14). To drain the hot water system, it is necessary to disconnect the water supply pipe and blow air through the water heater coil. 9.4 During operation, keep the temperature of hot water in the boiler no higher than 95 0C. 9.5 Using hot water from the heating system for domestic purposes is PROHIBITED. 9.6 For a gas-fired boiler, it is allowed to use a water heater in the summer when the heating system is closed. The water temperature, when flowing from the water heater, is regulated by a mixer or valve 12, increasing or decreasing the speed of water passing through the coil. When the water temperature in the boiler reaches 800C, the temperature sensor should stop supplying gas to the main burner. If there is no water flow for a long time (more than 2 hours) through the water heater coil, in order to avoid boiler boiling, any combustion in the boiler, including the ignition burner, is PROHIBITED. 9.7 For a boiler operating on solid fuel, the use of a water heater with the heating system turned off is not allowed.

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. Below in the video you can see a review from a person whose boiler leaked after a year of operation.

When planning a heating system in a private home, owners often try to find a universal solution that allows them to easily switch from solid fuel to gas. On the Russian market there are models of heating devices capable of solving this problem. One of such devices is the Don 16 solid fuel boiler. In this material we will talk about the features of its design, advantages and disadvantages, and also provide user opinions.

So what is this model? The Don 16 boiler is a steel household solid fuel boiler with a water circuit, designed for heating houses or other small premises and for organizing hot water supply. Wood or coal can be used as fuel, and with minor modifications, pellets or gas. Let's take a closer look at its design and find out what allows it to achieve such versatility.
