Long-burning solid fuel boiler Don: characteristics, owner reviews

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.

Advice! Due to the possibility of conversion to use gas, it makes sense to install Don brand boilers in those areas where gas supply will soon appear. When connecting gas, you will only need to install a burner of a suitable model without replacing the boiler.

• 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.

Advice! If, however, the coil fails due to increased water hardness, it can be very easily replaced without carrying out large-scale dismantling work.

• 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.

Advice! Consumers note the successful design of the ash collection chamber. The presence of massive grates ensures the movement of combustion products into a compartment specially adapted for this purpose.

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.

Advice! Equipment for servicing the boiler (poker, scoop, etc.) is usually not included in the delivery package; they will have to be purchased separately.

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.

Main features of boilers

The Don gas boiler has a number of design features that must be mentioned in this article so that the potential buyer has an idea of ​​what he is paying money for when choosing equipment from the Rostov brand. Among the advantages we note the following:

• The equipment is equipped with a highly reliable gas burner and thermo-hydraulic automation, ensuring its stable operation.
• Possibility of operation on various types of fuel.
• High efficiency when heating large areas.
• Excellent efficiency and high efficiency. This result was achieved by engineers with a special water jacket device. During operation of the unit, the coolant is distributed throughout the entire body of the device. At the same time, the outside of the boiler is covered with a special heat-insulating material designed to reduce thermal energy losses.
• High structural strength achieved through the use of thick high-quality steel as the body material. In addition, the equipment is able to withstand serious pressure drops, which is also a definite advantage and relevant for Russia.
• The boiler is equipped with a 3-turn exhaust gas passage system, which increases its efficiency.
• Small dimensions and light weight, which simplifies installation and transportation.
• Easy maintenance and cleaning of the boiler, thanks to the horizontal arrangement of the doors and chimneys.
• The ability to clearly regulate the temperature in the room using convenient and stable built-in automation.
• High power and reliability of the units, as well as safety.

Let's take a closer look at several variations of the Don gas boiler.

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.

Model range of boilers Don

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

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.

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:

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.

Don 16 by installing a pellet burner and a hopper with a control unit can easily be converted into a Russian-made pellet heating boiler. Unlike gas equipment, connecting equipment for working with pellets does not require registration. Pellets are much more efficient than firewood and coal and will help you save significantly on heating your country house or cottage.

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.

Dual-circuit

These are models KS TVM 16/20, TV 31.5/40, TV 20 and others.
A number of dual-circuit heaters can be easily converted from gas to coal/wood and vice versa. Designed for heating areas up to 300 m². Simultaneously with heating, they heat water for domestic needs. The secondary circuit is a copper coil; if necessary, it can be changed, thereby prolonging the operation of the equipment.

A double-circuit boiler has characteristics almost similar to those of a single-circuit boiler. Also made of steel, but more powerful than single circuit versions. 20, 30 and 50 kW options are available. Their weight is 150–200 kg.

Model range of boilers Don

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.

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.

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. 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

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.

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.

It just so happened that a DON16 solid fuel boiler was purchased for heating, which honestly worked out its low cost for two seasons using wood (sometimes damp). A serious drawback of this, and all domestic boilers, is the complete absence of at least some kind of automatic combustion temperature control. After surfing the forums, I discovered that Czech solid fuel boilers DAKON are able to regulate the air supply to the firebox themselves. Having called several companies selling DAKON boilers, I discovered that the thermostatic valve for them can be purchased separately and it is quite suitable for DON 16 boilers with minor modifications. I show what happened in the photo.

2Nikolasd and how does it burn now?

It became a little easier with adjustments. It’s not a bad idea to run to him every 20 minutes. While the antifreeze is cold, the ash door is open; when it heats up to the desired temperature, it closes. Accordingly, the air supply and antifreeze temperature are reduced. It’s too early to say whether it’s better or worse, it’s only been working with the thermostat for 2 days.

In general, of course, you need to look towards the Czech DAKON. At the time when the Czechs bought DON 16, it seemed expensive and they did not have a second circuit for hot water, which helped us out this winter until the Termex storage water heater was installed.

I think that there is no need to look in his direction so clearly. Your Don is no worse (looking at the photo), and overpaying is not economical.. ( ) I’m installing an old KChM for myself (I saved 500 euros for the vaunted abroad)

Well, adjusting the blower is only one of its big problems; there is another one that is not as easy to deal with as the blower. The problem is this. The combustion process in the DON 16 boiler, as in other similar boilers, occurs throughout the entire volume of its firebox, which means that the wood does not burn evenly, that is, first when it flares up from below, then evenly throughout the entire volume of the firebox and gradually burns out downwards. The result is surges in generated heat and rapid fuel burnout for 3-4 hours.

In the new generation Czech boilers with wood loaded not from the side but from above, the wood burns only in the lower part of the firebox. The combustion occurs not vertically, as in DON16, but horizontally. This apparently ensures high uniformity of heat transfer. Gradually burning out, new, untouched firewood is lowered to replace the burned-out ones, and so on until the load is completed. Combustion and heat transfer with this approach should be much more uniform than in DON 16.

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.

Advantages of solid fuel boilers Don

According to the manufacturer and consumer reviews, the Don wood-burning boiler has the following advantages:

Due to the fact that the Don solid fuel boiler can be converted into a gas one, it is logical to install it in places where gas supply is planned in the future. When supplying gas, you only need to install a burner device of the required model without replacing the boiler.

1. The device is universal. It can operate on almost any solid fuel, be it logs, coal, peat briquettes, wood waste (pellets, shavings, etc.). In addition, if necessary, you can install a gas burner.
2. Does not depend on the power grid. The boiler does not need power from the network, so it is not afraid of a power outage.
3. Has a long service life. The combustion chamber is made of high strength steel and high carbon content. The thickness of the steel sheets is 3 mm. This material is characterized by resistance to high temperatures and corrosion processes. It has excellent thermal conductivity.
4. Safe. The body of the heating device is well thermally insulated, which increases operating performance due to reduced heat losses, and also eliminates heating of the outer surface. The equipment is completely fireproof.
5. Large gaps between fuel fillers. Almost all models from the Don range have large-volume combustion chambers. This increases the interval between fuel fills to eight hours, which is, accordingly, much easier for the owner.
6. Possibility of using low-quality coolant. The boiler can also cope with hard water.
7. Rigor and versatility of design. The outside of the boiler is covered with heat-resistant paint, which maintains the decent appearance of the heating device for a long time.
8. High-quality execution. The boiler casing has no gaps, all elements fit together well. The threaded connections are made perfectly, the joints are welded adequately.
9. Affordable price. It's reasonably priced, and the fuel won't empty your pocket.
10. Work is always under control. The built-in thermostat controls the temperature in the system.

You can learn more about the types of boiler burners from.

If such a problem does arise, when the coil fails due to the use of very hard water, the device can be easily replaced without major dismantling work.

The owners point to the clever ash chamber in the design. Thanks to the presence of massive grates, combustion products are moved to a specially designed niche.

Cauldron Don 16: the power of an improved classic

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 the 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.

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 does a solid fuel boiler Don work?

The design of the equipment in question is a steel body with two doors, the upper door is intended for loading fuel, the lower one is for removing ash from the furnace, and an ash-blower is built into this door. Inside the housing there is a water jacket for heating the coolant with a bumper to increase the heating area and more efficient heat removal. The boiler water jacket has inlet and outlet pipes for connecting the heating system.

Ash pan of the Don 16 boiler of the old modification

Cast iron grates are installed at the bottom of the combustion chamber, onto which solid fuel is loaded. The firebox can accommodate up to 15 kg of firewood. To supply hot water, a copper coil is installed inside the boiler. To remove combustion products, a chimney is located at the top of the combustion chamber after the bumper and swirler, which is connected to the chimney. To adjust the draft or vacuum in the firebox, there is a special adjustable slide valve. Thermal insulation is installed between the body and the casing, allowing it to accumulate all the heat from fuel combustion to heat the coolant. It is also equipped with a sensor and coolant temperature indicator.

Gas burner for solid fuel boiler with water circuit Don 16

It must be said that Don solid fuel boilers can also operate on gaseous fuel. This is achieved by installing a gas burner of the AGUT-M type. Making the transition from solid fuel to gaseous fuel is very simple. To do this, remove the grate, dismantle the lower door, and in its place install a burner with automatic control and connect it to the gas supply system. A very important issue when switching to gaseous fuel is obtaining permission to connect from the gas supply organization. A converted gas boiler should only be connected by an organization that has the appropriate permission to do so. Do not attempt to do this work yourself.

Peculiarities

The Don solid fuel boiler will efficiently heat your home and other premises and will be able to ensure the supply of hot water. The device is characterized by its own characteristics and has both advantages and disadvantages.

As for the features, Don boilers consist of a water jacket and smoke pipes. The pipes that are removed from the combustion chamber are passed through the water jacket of the device. In order to increase the efficiency, turbulators are installed in the pipes. A special temperature sensor controls the water heating temperature.

Water is heated by convection and enters the heating system through the upper pipe of the device. Through the lower pipe, liquid is supplied to the boiler, which has already given up its energy in the batteries and pipes.

Long-burning solid fuel boilers Don are produced as single-circuit (for heating) and double-circuit (for heating and hot water). In the latter case, the pipeline is connected to a copper coil located in the boiler. As the liquid passes through this device, it heats up. To regulate the heating of the liquid that is supplied to the water supply, the speed of its passage through the coil is changed by turning the valve.

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.

Methods for adjusting temperature conditions

Let's consider this case - you purchased a gas boiler, the technicians installed it and adjusted the settings, setting a certain operating mode. But one fine day it became colder outside, and the previously established heating indicators no longer met the new realities. Then the owners have a question about how to increase the temperature on a gas boiler. This can be done in different ways, which depend on the model of the unit. Conventionally, methods for increasing temperature can be divided into:

• mechanical;
• electronic.

Which method is suitable in a particular case can be seen in the operating instructions for the gas boiler.

Read here about the choice of voltage stabilizers for gas boilers

Mechanical methods involve manual adjustment of the gas boiler settings. This addition of temperature is carried out with simple models of units, for example, AOGV or those produced by the Zhukovsky plant. Electronic regulation is provided automatically by a built-in or connected thermostat. This function is available on many modern models of gas equipment.

Technical characteristics and dimensions

Please note that the technical characteristics of various models, as well as their prices, will differ depending on the maximum size of the heated area

Although the total cost is significantly influenced by additional components that are purchased optionally

These include draft regulators, fasteners, various angles and tees with special, temperature-resistant insulation, as well as sandwiches of 0.5 and 1 meter. In the same category are replacement coils, which are necessary in case of damage or wear of previously installed ones.

In the same category are replacement coils, which are necessary in case of damage or wear of previously installed ones.

The characteristics common to all models, including those equipped with gas burners, can be described as follows:

• universal, since they can use both natural gas and firewood, peat layers or pellets for heating;
• safe and economical because they do not transfer temperature from the combustion chamber to the casing;
• durable, because the thickness of the walls of the combustion chamber is at least four millimeters;
• adapted to hard water and the consequences of its use, this is possible thanks to the removable coil;
• have a long service life, the boiler can work in autonomous mode for up to eight hours in a row (this only applies to options for using solid fuel).

Possible equipment dimensions:

• heating area up to 140 m²: dimensions - 1030 by 430 by 410;
• heating area up to 180 m²: dimensions - 1180 by 430 by 410;
• heating area up to 300 m²: dimensions - 1430 by 650 by 650.

Useful tips

Advice! When choosing a boiler, it is better to consult with professionals. At the same time, these people should not only be experienced installers, but also be able to make a thermal energy calculation that allows you to calculate the required power of the equipment as accurately as possible. If this rule is not followed, then there is a high risk of the system freezing, and, consequently, its failure in severe frosts.

Before installing the heating boiler, the instructions must be carefully studied. It is attached to the supplied equipment and contains not only a thorough description of the technical parameters, but also detailed installation instructions. With the right approach to installation, the equipment will serve you for many years without the need for additional repairs.

For additional information, you can always watch a video on our website about the operation of any of the models, although in the photo everything is quite clear and understandable even for a beginner in the field of heating.

For reliable operation of Don boilers, proper installation of the chimney for a solid fuel boiler is very important. The optimal solution may be to choose a Sandwich pipe. It consists of two parts with different diameters, and the entire structure is insulated using absolutely non-flammable mineral wool

Such a chimney will be very inexpensive, will be quite easy to install and will extend the life of the equipment

How to heat a solid fuel boiler as efficiently as possible?

Firewood, coal, briquettes or pellets are used to fire a solid fuel boiler. Depending on the specific model of the unit, the highest efficiency of the heating system can be achieved by using a certain type of fuel. Also, the efficiency of the boiler is directly affected by the quality of the combustible material and the method of its placement. A competent answer to the question “How to properly heat a solid fuel boiler?” will save a significant amount of money on the purchase of fuel, and at the same time will have a positive effect on the ease of operation of the heating unit.

What is the best way to heat a boiler?

The optimal fuel for a boiler is the type for which it was originally designed based on its design. Thus, solid fuel (SF) long-burning units are focused on the use of coal as the main fuel. Conventional cast iron boilers such as Buderus, KChM-5, Viadrus or Prometheus can equally successfully process briquettes, pellets or firewood, as well as coal.

Many nuances arise when considering the convenience of the combustion process itself. The most important question in this matter is how often should you add fuel to the boiler? And here, in addition to restrictions on the volume of the firebox of a particular model, you should focus on the combustion rate of a certain combustible material. Let us consider from this point of view the four most common types of fuel.

1. Dry wood burns out faster. There are even a number of techniques for them that allow you to prolong the combustion process of this material in the firebox. These techniques will be discussed in more detail later, but they make it possible to increase the intervals between approaches to the boiler by only a few tens of percent. A much more noticeable increase in the duration of fuel combustion is provided by the use of sawdust briquettes or “Eurowood”.
2. Eurofirewood is dried sawdust compressed into small briquettes. They burn 1.5-2 times longer than dry wood. Peat briquettes are also produced in a similar way, which show higher heat transfer. But here it is important to consider that peat-based fuel contains a significant amount of ash, comparable to coal. Therefore, the use of peat briquettes is only appropriate for water heating boilers with grates.
3. Coal takes longer to burn than other combustible materials. Some automatic coal boilers, so-called “coal automatics,” allow you to maintain a stable temperature in the house even in severe frosts for up to two days. This effect can only be achieved by using high-quality coal - anthracite, as well as installing an additional heat accumulator.
4. As for pellets, by burning them you can achieve the highest efficiency of the heating system. However, this type of fuel is also the most expensive combustible material. Even the highest quality anthracite coal will ultimately cost 10-15% less than heating with good pellets. Good pellets burn much longer than sawdust briquettes and are only slightly inferior to coal.

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.

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.

Gas boilers Conord: review, design, automation

It's no secret that imported floor-standing gas boilers are of higher quality compared to domestic boilers. This applies to the material used to make the elements, the reliability of the automation, and the assembly of the device. However, the price of imported analogues differs noticeably upward. Our task is to find a Russian-assembled gas boiler with an optimal price-quality ratio.

I propose to disassemble Conord floor-standing gas boilers, reviews of which can increasingly be found on various thematic forums. Let's consider the model range, technical characteristics, device, types of automation (gas burner devices), using the instructions for use.

Model range and description of Conord boilers

Conord floor-standing gas boilers are available with capacities from 8 to 30 kW. They come as single-circuit: KSts-G-8, KSts-G-10, KSts-G-12, KSts-G-16, KSts-G-20, KSts-G-25, KSts-G-30; and double-circuit: KSts-GV-10, KSts-GV-12, KSts-GV-16, KSts-GV-20, KSts-GV-25, KSts-GV-30.

Single-circuit ones can only be used for heating from 30 to 300 m2. Conord double-circuit gas boilers can be used for both water heating and hot water supply (DHW).

Floor-standing gas boilers Conord

There is no point in buying, for example, a double-circuit boiler KSts-GV-12 with a power of 12 kW. It will not give us a good volume of hot water.

Boilers can be used in both open and closed heating systems.

Installation of floor-standing gas boilers Conord

The boiler consists of a steel firebox 3 mm thick, a casing, a water jacket, smoke pipes with turbulators built into them to increase the efficiency of the boiler, a gas burner device (automation), a layer of thermal insulation made of basalt cardboard, and a thermometer to monitor the temperature of the coolant. In double-circuit models, a special coil for the water circuit is installed around the smoke pipes.

The coolant inlet and outlet, as well as the DHW coil, are located on the rear side of the boiler body. The thread diameter of the heating connection pipes for all models of this brand is 2 inches or 50 mm. For DHW circuit 1/2 or 15 mm. The chimney diameter for models with power from 8 to 12 kW is 115 mm, for 16 kW and above - 150 mm.

Conord boiler design

Automation for gas boilers Conord

Three types of automation can be installed on floor-standing boilers of this brand:

— domestic type AGU-T-M

- Italian Euro SIT

In general, the automation, although not particularly sophisticated, is unpretentious. In the event of a breakdown, it is not difficult to find spare parts for it. For example, a bimetallic strip that often fails costs about 50 rubles.

Automation type AGU-T-M

Ignition occurs by pressing the piezoelectric element button or using a match. The coolant temperature is provided by the gas valve and set by the thermostat knob.

Automation Euro SIT

Ignition is carried out by pressing the handle to the right of the thermostat and then turning it to the stop position to operate the boiler in economical mode.

— wide model range — three types of automation — cost-effectiveness — high efficiency — in case of boiler malfunction it’s easy to find spare parts — good thermal insulation

Disadvantages of Conord boilers

— build quality — steel thickness no more than 3 mm — price

The price of Conord boilers starts from 13,000 rubles for the most budget and low-power model. Still, it's a little expensive. For similar money you can already buy, for example, an imported floor-standing gas boiler “Protherm Wolf”, assembled in Slovakia. But it's up to you. Let's watch the video.

The first start-up of the heating system is a crucial moment on which the serviceability of its elements, coherence and uninterrupted operation depend.

How to turn on a gas boiler, fill the radiators with coolant, bleed the air, check everything and not forget anything.

Consider the procedure and rules for putting the heating system into operation.

If the boiler is new and you do not want to lose the possibility of warranty service, you will have to invite service employees. They will make a corresponding note in the passport stating that the first launch was carried out according to all the rules.
