Even a hot summer, a good owner remembers the occurrence of winter. Therefore, he thinks about how his dwelling will be heated during the cold weather. The question arises how to choose a good way of heating, which at the same time will be economical. If there is an opportunity to equip gas heating for this purpose, then this problem is solved easily. However, if for some reason it is impossible to install it, then you have to look for alternative ways. One of them is the use of pellet boilers. Buying them today is not a problem. After all, in recent times, their popularity is only growing.

Characteristics of pellen boilers

This heating equipment is a solid fuel boiler that works on small granules called pellets. They are manufactured by pressing wood processing waste.

Proof of the popularity and accessibility of solid fuel pellet boilers can be the fact that today around Europe has already been established and successfully operated about one million of such installations.

Sheet steel used for the manufacture of these heating devices. The design includes the following mechanisms:

1. Pellet burner boiler.
2. The conveyor serves fuel into the combustion chamber.
3. Bunker for storage granules.

The principle of their work is that pellets are served from the bunker to the firebox of the boiler using a special auger, which, in turn, is controlled by automation. When combustion of fuel, thermal energy is distinguished, warming coolant, which is distributed through the dwelling.

Obviously, with an increase in the required heat, the costs of fuel are increasing. When the air temperature in the house reached the necessary, the auger stops feeding the granules into the boiler. As for the bunker, it is usually selected in this size so that fuel is enough for several days when it is fully loaded.

Undoubtedly, there is a difference between fossil fuel and wood granules, which are pellets. This is a very eco-friendly resource. It is also good because wheels of wood are involved in its production. That is, what is often ejected, it is started into the case. Today it is not necessary to buy pellets.

The combustion chamber, which is equipped with a pellet boiler, allows to get a rather high efficiency of the efficiency. High-class equipment can reach 96%. As a heat exchanger material, cast iron and steel are mainly used. Each of them has its advantages and disadvantages. Thus, the cast iron is highly resistant to corrosion, but at the same time poorly tolerates hydraulic strikes. As for steel, then the situation can be said to be reverse - it is not sensitive to sharp increase in pressure, but unstable to rust. Therefore, steel heat exchangers need to be used by special means.

Modern pellet boilers are equipped with automatic control, due to which the fuel supply is adjusted and the set temperature is maintained. Pellets need to fall asleep in the bunker only once in 2-14 days. The amount of loads depends on the volume of the capacity. When servicing equipment, it is also necessary to periodically clean the smoke channels and remove ash from a special box.

From 10 to 50 years - service life of a pellet boiler. The price of aggregates on average is 90-100 thousand rubles.

Types of aggregates

Pellenic boilers are used not only for the heating of buildings, but also to ensure hot water. Today, depending on the power, several variants of such aggregates are available - from 15 to 100 kilowatt.

These equipment also distinguish with the types of fuel used:

1. Boilers working only on pellet.
2. Units operating on briquettes and firewood. In the second form of fuel, they can only work a few hours.
3. Combined equipment operating on pellet, coal and firewood. Such boilers have several combustion chambers.

Types of pellets

Distinguish:

1. Solid wood pellets without bark. They are usually used for the heating of residential premises. Their structure is dense, and the color is white.
2. Dark pellets. Made from wood with bark. They are used for heating industrial enterprises. They have a smaller efficiency. With their combustion, more harmful waste is produced.
3. Pellets that are made from agricultural waste. They are considered less effective.

Advantages of pellet boilers

This heating equipment has many advantages. It should be selected as follows:

1. Small fuel consumption. This is achieved due to the fact that the granules burn almost without residue. Consumption mainly depends on their quality and composition. On average, the pellets must be twice as fewer to heating the premises of the same area than ordinary firewood.
2. Low fuel price. Pellets are less than other types of fuel.
3. Reparatively low cost of boilers. They cost less than similar devices operating on another type of fuel.
4. Do not depend on electricity. Although there are models equipped with several electrical appliances.
5. Easy service.

How to choose a pellet boiler

When choosing this type of heating equipment, you need to pay attention to some important factors.

1. For example, you should choose a boiler with a suitable type of burner. They are two species - retort and ancient. The first produce a flame up. Such burners are not demanding of the fuel quality. In addition, they do not need to be cleaned often. Unlike them, the traffic burners produce a flame in a vertical position. In addition, they are much more demanding on the quality of fuel and work best on low-rise grains. In addition, such a burner must be cleaned much more often, because She quickly clogs. Obviously, preference should be given to remote burners.
2. In addition, you need to decide which boiler automation level you need. Today there are models of automatic pellet boilers, which can work autonomously for several days, i.e. without human participation. There are still aggregates in which there is a control function by sending SMS from the number of the owner's phone number. Thus, with them, you can, for example, include or disable the equipment, as well as adjust the temperature. If an emergency situation arises, then the automation of the boiler will tell the owner on this.

Pellet boilers also vary by the type of fuel of the auger. It happens two types: hard or flexible. Each of them has their advantages and disadvantages. Of the advantages of the rigid auger, the following should be noted:

1. Easy design.
2. Low price.
3. Simple mount, which guarantees the reliability of end parts.

From its disadvantages, you can select the following:

1. It is limited in length, i.e. There can be no more than 2 meters.
2. Space is irrational. The bunker is tied to the burner, because of which it is impossible to change its position.

Flexible auger has no indicated shortcomings. His dignity is that it allows you to install the bunker of any size. However, it is equipped with a rather complex fastening system.

When choosing a pellet boiler, it is important to know that there are several designs of heat exchangers. So, distinguish:

1. Horizontal and vertical.
2. Tubular and flat.
3. With a different number of moves and turns.
4. With swirls of exhaust gases.

It is believed that boilers with a vertical arrangement of the heat exchanger are the most effective. They allow most of the thermal energy to use with benefit, i.e. Heated heat carrier.
