In most rural settlements of Russia there is no gasification. When it becomes necessary to equip 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 line of models is able to satisfy the most demanding customer. In addition to differences in power, these boilers are delimited by the principle of combustion:
- The classic scheme. This option involves heating the coolant in a jacket directly in contact with the combustion chamber. The design is quite simple and reliable, but has a low efficiency.
- Gas generating models. In them, combustion occurs according to 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 the high efficiency, can save on fuel.
In addition to these varieties, the company released models of long burning. However, they remained unclaimed in the Russian market due to their high cost.
Cast iron and steel boilers
Products of the Dakon company are made of steel and cast iron. The various properties of these materials make it possible to make boilers working both on wood and on coal. There are also combined options.
Dakon steel 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 work in optimal temperature conditions. The draft regulator makes it possible to smoothly change the heating of the liquid both manually and automatically. Fuel loading occurs through the vertical, expanding upward hopper. The heating equipment "Dakon Dor" is universal - it can burn any solid fuel: firewood, briquettes, coal.
Cast iron boilers have a higher cost and are marked Dakon FB. Compared with steel products, they are durable, not subject to corrosion and burnout. It is possible to change operating modes, as well as enable additional blowing. This allows you to burn wood and coal equally efficiently. The heating medium is also regulated via an automatic draft regulator. The heat exchanger has several sections for efficient heat transfer.
Pyrolysis burning
Equipment marked Dakon KP PYRO refers to pyrolysis boilers, the high cost of which is offset by economical operation. Combustion is carried out in two chambers. In the first, 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, therefore, the boiler needs electricity. This scheme allows you to increase the combustion process in time up to 5-10 hours. What affects their cost. The price of boilers for solid fuels of long burning varies from 95 thousand rubles.
Gas generating equipment uses any kind of solid fuel, but the most efficient work is achieved by burning wood. In order for the efficiency to correspond to that declared by the manufacturer, the wood must have a moisture content of not more than 20%.
Safety regulations
Solid fuel boilers "Dacon" already have a built-in security system. In the event of a sharp increase in pressure, it will preserve the integrity of the water jacket. Nevertheless, do not neglect the standard installation of the security group of the heating system. Installing the included thermometer will allow you to accurately monitor the temperature of the liquid and prevent its overheating.
To reduce scale and foreign matter in the coolant, mechanical filters are used, as well as a liquid that reduces the formation of calcium precipitation. This makes it possible to maintain the efficiency of heat transfer.
What criteria to choose
When buying a solid fuel boiler "Dacon" the question always arises: which model to choose? To do this, consider several criteria:
- Power. For heating a well-insulated house up to 100 square meters. m option suitable for up to 10-15 kW.
- Autonomy or volatility. If in the area where the boiler room is equipped, there are power outages, it is better to look in the direction of options that do not require forced air supply for operation. Accordingly, these are the models Dakon DOR and Dakon FB.
- Thrift. Boilers with high efficiency and long run times on one tab belong to the Dakon KP PYRO models.
- Life time. The manufacturer assures that the average period of use of steel boilers is 10-12 years, and cast-iron - 25 with proper care and compliance with 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, it is worth paying attention to the reviews of real users. Always in the process weaknesses and strengths are revealed, such as ease of cleaning, ease of loading, stability in work.
