In most rural areas of Russia there is no gas supply. When it becomes necessary to arrange autonomous heating, the problem arises of choosing the appropriate equipment.
Among the many models on the Russian market, Dakon solid fuel boilers have established themselves as reliable and durable heating devices.
Differences between boilers
The range of models is able to satisfy the most demanding customer. In addition to the difference in power, these boilers are distinguished by the principle of combustion:
- Classic scheme. This option provides for heating the coolant in a jacket that is in direct contact with the combustion chamber. The design is quite simple and reliable, but has a low efficiency.
- Gas generating models. In them, combustion occurs in a double scheme. Pre-combustion causes the fuel to release pyrolysis gas, which subsequently enters the afterburner. Such solid fuel boilers "Dacon" are more expensive, but, due to their high efficiency, they allowsave on fuel.
In addition to these varieties, the company has produced long-burning models. However, they remained unclaimed on the Russian market due to their high cost.
Cast iron and steel boilers
Dacon products are made of steel and cast iron. The various properties of these materials make it possible to make boilers working on both wood and coal. Combination options also exist.
Dakon steel heating boilers with equal power have a lower weight. They are resistant to pressure drops in the system. They do not require careful transportation, unlike their cast-iron counterparts.
The most popular model is Dakon DOR. It has a built-in safety system against high pressure and overheating. The product is equipped with a three-section heat exchanger, which allows the boiler to operate in optimal temperature conditions. The draft regulator makes it possible to smoothly change the heating of the liquid both manually and automatically. Fuel is loaded through a vertical bunker expanding upwards. Heating equipment "Dakon Dor" is universal - it can burn any solid fuel: firewood, briquettes, coal.
Cast iron boilers are more expensive and are labeled Dakon FB. Compared to steel products, they are durable, not subject to corrosion and burnout. It is possible to change operating modes, as well as to turn on additional blowing. This allows you to burn both wood and coal equally efficiently. Adjustmentheating of the coolant is also carried out through an automatic draft regulator. The heat exchanger has several sections for efficient heat transfer.
Pyrolysis combustion
Equipment marked Dakon KP PYRO refers to pyrolysis boilers, the high cost of which is offset by economical operation. Combustion takes place in two chambers. In the first one, the fuel is preheated in the chemical underburning mode. Then the released pyrolysis gas enters the afterburner. There it is additionally mixed with air, and it ignites.
It should be noted that the air supply is forced, so the boiler needs electricity to operate. This scheme allows you to increase the burning process in time up to 5-10 hours. What affects their value. The price of long-burning solid fuel boilers varies from 95 thousand rubles.
Gas generating equipment uses any kind of solid fuel, but the most efficient operation is achieved by burning wood. In order for the efficiency to be as declared by the manufacturer, the wood must have a moisture content of no more than 20%.
Safety rules
Solid fuel boilers "Dacon" already have a built-in security system. In the event of a sharp increase in pressure, it will maintain the integrity of the water jacket. However, do not neglect the standard installation of the heating system safety group. Installing the included thermometer will allowprecisely monitor the temperature of the liquid and prevent it from overheating.
To reduce scale and foreign inclusions in the coolant, mechanical filters are used, as well as a liquid that reduces the formation of calcium deposits. This makes it possible to maintain the efficiency of heat transfer.
By what criteria to choose
When buying a solid fuel boiler "Dacon" the question always arises: which model to choose? To do this, you need to consider several criteria:
- Power. For heating a well-insulated house up to 100 sq. m suitable option with a capacity of up to 10-15 kW.
- Autonomy or volatility. If there are power outages in the area where the boiler room is being equipped, then it is better to look towards options that do not require forced air supply for operation. Accordingly, these are the Dakon DOR and Dakon FB models.
- Frugality. Boilers with high efficiency and long operating time on one tab are Dakon KP PYRO models.
- Service life. The manufacturer claims that the average life of steel boilers is 10-12 years, and cast iron boilers - 25 years with proper care and observance of operating rules.
- Financial opportunities. The higher the efficiency of the equipment, the greater its cost. Therefore, pyrolysis boilers are the most expensive.
Also, when choosing, you should pay attention to the reviews of real users. Weaknesses and strengths are always identified in the process, such as ease of cleaning, ease of loading, stability in operation.
