Solid fuel boiler Don (Conord): technical characteristics, device, instructions

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 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.

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.

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.

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.

Boiler structure

Construction of Don boilers
The water jacket of the Don furnace is made in such a way that the energy carrier is distributed throughout the entire body of the unit. The heat exchanger and housing are insulated with low thermal conductivity material, so energy is stored inside and the box remains cool. The firebox and body of the boiler are made of 3 mm thick steel.

The Don brand provides the opportunity to replace the copper coil in the water heating system. In hard water, the element quickly fails; replacement will extend the life of the equipment. The forced method of removing combustion products allows you to make a horizontal chimney. The manufacturer provides a warranty on the boiler for 12 months from the date of sale or 15 months from the date of manufacture if there is no sales stamp.

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.

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.

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.

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.

In addition to the universal boiler with a power of 16 kW, 30 kW models are also available. The line also includes devices capable of operating only on solid fuel. Here are some technical characteristics provided by the manufacturer on the official website:

ModelKS-TG-16/20SKS-TG-30/40S

To ensure operation on gas, the screw door and grate are dismantled, and an automatically controlled gas burner is mounted in the lower hole of the front panel. The upper part of the firebox is covered with a firebox sheet close to the front wall.

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.

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.

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 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.

Brief operating instructions ↑

1). Fill the system with fresh water in small portions (maximum 8 l/min) until liquid is released from the overflow tube of the expansion tank. 2). Proceed with kindling, focusing on the nature of the fuel: I. Ignition of the CT: a). open the primary air plug, bring a rolled newspaper to the gap between it and the screw valve, make sure there is traction (the pages will be pressed); b). Fill the receiving chamber evenly halfway with firewood, set it on fire, and when ignited, pour small (up to 25-30 cm) pieces of coal on top; V). put no more than 5-6 kg of fuel at one time, spend about an hour loading the bunker; then set the gate so that the thrust is stable. II. Starting the gas burner: a). ventilate for 5-10 minutes. combustion unit by closing the main valve; b). check the traction force by bringing a sheet of paper closer to the viewing window; V). open the air supply valve, light the fire. 3). Close the doors; later adjust the temperature with a mixer or coil valve.

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.
