Nedelka boilers: technical characteristics, advantages and disadvantages

Heat producers boilers "Week" - an indispensable tool for summer residents who are forced to leave the city for the working week. Long continuous burning period - up to 7 days, the possibility of using different types of fuel, high performance and efficiency - these are not all the advantages of omnivorous boilers.

The difference from the usual heating boilers of these products is that there is no need to throw wood in them every few hours. Such convenience was appreciated by many owners of private houses, they are acquired for the heating system of cottages of different sizes.The nomenclature of models offered on the market allows you to choose the device of the required power.

When customers see structures of long burning, they are amazed at the size of the loading chamber. But this is not the main thing. Consider what causes the combustion process to stretch in the time range. Of course, not the amount of fuel, but its gradual combustion. The principle of operation of boilers "Week" of Russian production is based on the gradual ignition of fuel from top to bottom, while the lower layers remain uncovered by the flame.

The reason for the gradual burning is the regulation of the flow of air into the fuel chamber. It is only enough for the oxidative reactions of the upper layers. The resulting carbon dioxide protects other combustible materials from burning. With such a portion of the flow of air in the center of fire does not form a strong flame, it is not actively distributed throughout the volume of fuel.

With a gradual burning in the chamber of large volumes, the humidity of the air self-regulates, so the Nedelka boilers can be filled with wood and coal without prior drying. Fireboxes perfectly "eat" wet "food."

The design features of the boilers are visible immediately by the position of the firebox door. It is located at the top of the boot chamber. Almost the entire volume takes the firebox.

Another feature of the "long-playing" heat generators in the use of ash. It does not serve to create traction, but performs purely utilitarian functions: the remnants of the products of combustion of fuel are removed through it. Since the blower is not needed, the ash door closes tightly. Intake of air occurs from the chamber located at the top of the boiler. The air chamber plays the role of not only a supercharger, but also a heat exchanger: due to the structural solution, the exhaust flue gases heat the walls of the chamber supplying air and enter the fire chamber heated. The valve is located at the top.

Portion air supply is provided by the distributor. The size of the tube connecting the air chamber and the distributor is regulated by a telescopic structure. After settling the source of combustion, the distributor is also below the initial level. Therefore, air constantly enters the zone of ignition.After the combustion of all loaded coal or firewood, the distributor returns to its original position with the help of a hooked cable. The end of it is placed on the wall of the fuel, strengthened by a ring. The position of the ring is easy to determine the level of fuel. In case of complete combustion, the ring jerks back down - the regulator, in portions supplying air to the combustion chamber, takes the initial position.

The design of any boiler must include a heat exchanger. In models with the trademark "Week" water jacket covers the entire area of ​​the side surfaces. Due to this arrangement of the heat exchanger increases efficiency.

Connecting pipes, supplying and receiving coolant, crashes into the heating system of the house, creating a closed heating circuit. The upper connecting nipple, located at the top, feeds, through it water is poured into the boiler heat exchanger. From the bottom fitting the coolant enters the heating system by gravity. Under the pressure of the upper layers. This ensures circulation.

The most important quality for consumers of long-burning boilers is the time interval between refills of the firebox.

The advantage of boilers "Week" is primarily its reliability. It is largely due to the simplicity of the construction solution. Another indisputable advantage is the possibility of using low-quality fuels with high humidity.

Maximum heat exchange efficiency is achieved when used as combustible materials:

• brown coal;
• anthracite.

If they are not available, you can pawn the furnace:

• pellets;
• briquettes;
• firewood - the maximum size is indicated in the instruction manual.

Cons of the use of such boilers - dimensions. A seven-day supply of fuel must be put somewhere, therefore, depending on the power, heat generators of long burning occupy considerable space in the house.

The second operational nuisance is a large percentage of soot in the combustion products. It has the ability to settle on the walls of the furnace. When wet fuels are used, condensate forms, interacting with soot, and water forms carbonic acid. Therefore, the soot must be periodically cleaned. When using quality fuel, this problem is minimized, and the efficiency of the boiler increases.When building waste, especially tar-containing residues, wet sawdust, is loaded into the furnace, the volume of soot increases significantly.

Among other heat generators, “Week” is easily recognized by its rectangular shape. Depending on the power and the heated area of ​​the house, domestic products can work without refueling for up to 7 days. Efficiency is high - 92%. The design includes automatic devices that regulate the temperature of the coolant. Multi-pass heat exchanger, fire chamber with a grate partition and two doors: one for the ash pan, the other - a technological hatch. Designed to clean the internal walls of the furnace from the settled soot.

The control unit is located on top. When disconnected from the power, the boiler slowly fades out, unlike the analogs of “boiling” in it does not occur. When power resumes, it turns on automatically. The operation of the blower fan is also regulated by a microprocessor, the boost can ignite any type of fuel in a short time.

You can list five reasons for choosing the Nedelka boilers.

• Versatility. The boilers are not only for heating private houses. The operational characteristics make it possible to install them in industrial premises: they are not fire-hazardous, environmentally friendly - all doors remain tightly closed during operation and are safe in cases of power outages.
• Simplicity in service: for operation it is not necessary to pass special training, to receive admissions, one person will easily cope with it. The boilers are as safe as possible to maintain: every few days the furnace is cleaned, the ash pan is emptied, and the fuel is loaded.

• Difference modifications. Manufacturers produce "Week" of different capacities. Heat from the KO-60 is enough for heating 300 square meters, the power of the KO-110 is twice as high. Recently, due to an increase in demand for high-capacity heat generators, cluster modifications have been developed - modular boiler houses.
• Affordable price. The cost of domestic models ranges from 110 to 220 thousand. Imported boilers of similar design and power are much more expensive.The use of various types of low-quality fuel in the operation of a heat generator leads to significant cost savings.
• The durability of the boiler due to the use of metal from durable alloys. It has high fault tolerance. Warranty period of operation - 5 years, actual - not less than 20 years without replacement of structural elements.

Long-burning heat generators before industrial production were made by craftsmen in an artisanal way. The model has already been tested by time, it allows to significantly save on fuel. It is designed not only for heating systems, it can be used as a water heater.
