Description of gas boilers from the company Danko

Floor-standing gas boilers from the Danko company are very successful in the modern market for the sale of heating systems. This is facilitated by the fact that their products combine reasonable cost and good quality. Such devices are presented in a fairly wide assortment range, from which you can almost always choose exactly the model that will fill the house with warmth for many years.

Danko floor-standing single-circuit gas boilers are designed according to technologies well-known in Europe, and only according to those that have been developed recently, using the latest achievements in this field.

For cast-iron heating devices, extreme temperature changes are not scary. The main and distinctive feature of such structures is that they are adapted to any fuel quality. Therefore, when using the device, there are no complaints, even if gas of poor quality came through the pipeline.

The device gives off heat quite well, since the camera is tightly insulated. This is due to the fact that when insulating the object, sealants of a very high quality composition are used, adapted to weather changes and temperature.

And since the loss of heat in boilers of this type is minimized, gas is consumed quite sparingly, which helps to greatly save on fuel.

Many interior fittings are manufactured in European factories, but final assembly is done in-house.

How to choose?

Boilers are divided into the following types:

• Double-circuit wall. Their main advantage is their low weight and compactness. Combustion chamber - any type. Ignition is electronic. The device is protected from water freezing, there is an auto-diagnosis of malfunctions. Rated power 23.3 kW. The wall-mounted version is capable of heating an area up to 210 square meters. Consumes 2.76 cubic meters. gas per hour. The capacity of the membrane tank is 6 liters.
• Double-circuit floor. In them, the developers provide for protective automation, which stops the operation of the device in the absence of fuel, with insufficient traction, when the flame is extinguished. The power varies between 20-40 kW, and the heated area is 180-360 square meters. A wide model range is represented by modifications with heat exchangers made of cast iron or steel. The floor-standing version costs from 10 to 20,000 rubles - depending on the power and the used automation.
• Parapet. Water heating is provided. There is a sealed chamber. Chimney execution. The parapet version has piezo ignition and automatic protection. Burners - microflame. Heats 60-140 sq. M.
• Steel flooring. Single or double circuit. The flue is vertical / horizontal. 8-24 kW. Area - 701-90 sq.
• Cast iron floorboards. Open combustion chamber. They are used in closed and open heating systems. The type of circulation is any, natural or forced. High heat dissipation of the cast iron heat exchanger. 16-50 kW. Area - 150-460 sq.

What is a single-circuit boiler

The device in question is a device that has one heat exchanger that heats water, antifreeze or air, that is, a heat carrier. With the standard equipment received from the factory, it cannot be used for heating water and further using it for various needs of household purposes. It is this device that is called a single-circuit boiler.

Such heating systems are primarily aimed at heating rooms by creating the required comfortable temperature in them.

The name is given by the type of the device itself, that is, a single circuit passes through the structure through which the heated substance circulates. And if the factory equipment of the device does not allow you to immediately mount the system with the connection of a boiler for hot water, then in the future you can do it yourself.

By the principle of its operation, such a heating system is quite simple. Gas enters the furnace directly, during combustion it heats up the substance that takes on the function of a heat carrier and then there is a constant circulation through the pipes.

The circulation inside the system itself occurs due to the fact that a special pump is working and there is a big difference in the temperature of the most heated substance. In order for all the necessary rooms to be evenly heated inside the house, the circulation must go without disturbances.

If we consider the issue of additional heating, which can be carried out outside the circuit itself, then it can be done independently and without much effort. But when using a single heating circuit, if you still load it with heating a large volume of water in the boiler, then this situation will immediately negatively affect the heating operation. Since the performance will decrease and the consumption of combustible fuel will increase.

Therefore, if the house provides for a low consumption of hot water, of course, it makes sense to connect a small boiler, but if a lot of water is consumed and it is used often, then such an expenditure of funds is rather unprofitable.

This type of device has its own advantages:

• these heating structures are equipped with a system that automatically monitors safety. And also it sets the optimal parameters of the operating mode and consumption of the supplied fuel;
• it is convenient to install such systems around the premises in order to heat them; this does not require a large team of workers or special equipment;
• the period when such a boiler can be operated is quite long, if the installation is properly maintained;
• modern units have the ability, using a sensor, to respond to changes in the weather and automatically either heat up or switch to a more gentle mode of gas fuel consumption;
• since the design is quite easy to use, this also creates a certain comfort in its use.

• Parapet. 8 modifications - 7, 10, 12.5 and 15.5 kW. They are distinguished by their compactness. Single-circuit. No smoke. Can be installed in apartments with an area of ​​140 sq. M. The heat exchanger is made of steel.
• Steel. 22 models differ in power, number of circuits and location of chimneys.
• Cast iron. All have an open cell. Cast iron radiators last about 25 years.
• With a pump. 4 modifications. They work for space heating and hot water heating. Steel heat exchangers. Related security systems.

Range of heating equipment

• Solid fuel boilers... They are made in cast iron and steel, the projected power is 10–80 kW. The fuel for these boilers can be coal, firewood, briquettes, sawdust, woodworking and sawmill waste. It is possible to convert the boiler for gas and liquid fuel.
• Electric boilers... These boilers are designed on heating elements. There are two modifications - "Danko E" and "Danko EN" with a capacity of 3-18 kW and 3-12 kW, respectively. The design of these models has a three-stage system for switching on the heating elements, which determines the desired heating mode.
• Gas boilers... Agroresurs produces steel and cast iron gas boilers with floor and wall positioning with a capacity of 8–96 kW. There are models with open and closed combustion chambers. The big advantage of this type of models is their energy independence and the absence of forced ventilation.
• Gas convectors are produced in steel and cast iron with a capacity of 2–5 kW and 2.5–4 kW, respectively. When reinstalling the burner, these models are capable of running on LPG and both have a long service life of about 20 years. Convectors of this brand are technologically safe from overheating, thanks to the presence of a thermostat and have good heat transfer.

Boiler device on the example of Danko 10/12

The automatic unit is responsible for supplying fuel to the burners - the main and igniting ones, and for adjusting the water temperature. The gas supply stops immediately if:

• the flame is extinguished;
• gas pressure has become below the permissible value;
• there is no draft in the chimney;
• the coolant temperature has reached 90 ° C.

Double-circuit modifications consist of structural elements:

• chimney channel;
• blower fan;
• gas burner;
• heat exchangers - primary and secondary;
• hydraulic unit;
• connecting fittings;
• pump for forced circulation of water;
• expansion tank;
• an automation unit that controls the units of the apparatus.

A distinctive feature is that all components are produced by European companies.This is a plus in favor of the reliability and economy of Danko brand products.

Additional systems

In the device of gas heaters, the manufacturer additionally provided:

• water temperature sensors - triggered when boiling, turning off the system;
• a protective block that cuts off the gas supply when the wick decays;
• a block that stops the operation of the equipment in the absence of traction;
• traction control unit - for adjusting the flame;
• multidimensional protection block - disables the device in case of any type of threat;
• intelligent block - for the distribution of fluid flows.

Installation

It is necessary to take into account the rules for installing gas equipment:

• The power is selected according to the heating.
• There must be at least 25 cm between the body, installed on a fire-resistant horizontal platform, and a non-combustible wall.
• The apparatus can be placed near non-combustible walls if they are sheathed with steel sheet.
• The width of the passage in front of the facade is from 1 m.
• To improve the circulation of water, the installation should be carried out below the level of the heating devices.
• The expansion tank is located at the very top of the system.
• The minimum chimney length is 5 m.
• By placing the chimney outside, it has to be insulated.
• The diameter of the flue gas outlet must be larger than the diameter of the flue gas outlet.
• At the junction of the boiler and chimney, it is necessary to seal with a solution of cement or clay.

Operation and maintenance

Commissioning is possible after acceptance by gas service representatives. The installation diagram is attached to the instructions. Installation is quite simple, but it is better to trust specialists. Gas workers who take the device into operation are instructed accordingly. The modification is selected according to the project carried out by the gas service, in which the power of the apparatus and its type must be noted. Safety regulations:

• The device can be serviced by those who have listened to the instruction.
• In the event of a breakdown, immediately close the taps.
• If you smell gas, close the valve, open windows and call the gas workers.
• Keep the device clean and in good working order.
• Clean the chimney as often as instructed in the instructions.
• Check that the system is full on a weekly basis - if there is water in the expansion tank.
• At the end of the service life of the device specified by the manufacturer, invite a specialist for advice - whether it can be further used.

Advantages and disadvantages

The advantages of Danko floor-standing boilers include:

• The design of the units is optimized for the most efficient and economical operation in all conditions.
• Boiler assemblies and parts are made of high quality materials using modern equipment.
• Fuel consumption has been reduced by one and a half times compared to the products of other companies.
• The units are designed for a long service life.
• Attractive appearance, compact size.
• Relatively low price.

The disadvantages of Danko boilers can be considered:

• Demanding water quality, the need to use softening filters.
• The need for annual inspection and maintenance.
• Cases of random flame attenuation due to the reverse thrust effect are often noted.

NOTE!

The disadvantages of Danko boilers can be partly overcome by proper installation, and partly are a specific design feature.

What are the problems?

The simplicity of Danko's design allows its owners to independently carry out minor repair work. One of the most common problems is blowing out the burner. This is especially common in strong winds. Usually no malfunction is found, the wind is the culprit of the problem, but it is better to check the following points:

• Is there a non-return valve installed in the flue. If not, then there will be no reverse thrust, which is why attenuation occurs.
• If the chimney is installed incorrectly, it becomes clogged with soot and other combustion products - it must be cleaned.

It happens that an extraneous noise is heard before attenuation or an increased fuel consumption is observed - this may indicate a failure of the controller. The task is to repair or change a spare part.

Important! If you do not want to face the damping of the flame, choose not a single-circuit, but a double-circuit boiler - wall-mounted or floor-standing. 2-contour models have no such disadvantages.

Another common problem is ignition fading. It goes out due to the operation of the thermostat, which shuts off the gas supply if the burner does not heat up to the desired temperature.

Modification of gas boilers

Danko floor-standing gas boilers are the most profitable heating structures, because their modification is simple, convenient and economical.

1. Some models may well fit in a bathroom or kitchen, as they are about the size of a small washing machine. Therefore, such units are easy to install in any convenient place.
2. Other models have such a unique quality as the transfer of the entire chimney system directly to the roof of the building. Of course, this assumes that the installation will have to be installed in a strictly designated place, but still this approach is most convenient.
3. New heating systems provide greater efficiency with less fuel consumption.
4. There is another good innovation - a simpler smoke exhaust system.

The manufacturer constantly makes sure that his devices are created taking into account all modern achievements.
