A pellet boiler is a steel or cast iron unit that is used to heat rooms. Wood pellets (pellets) are used as heating raw materials for such equipment. Such stoves are an alternative to gas-fired heaters. From the article you will learn the main characteristics that pellet boilers have: prices, power, etc.

Pellet boilers: prices and characteristics of models from different manufacturers

Pellet boilers have appeared on the market for a long time and have managed to establish themselves as highly efficient heating systems.

What is a pellet boiler?

In fact, such a device is a solid fuel stove, which heats the room by processing pellets. What is a pellet? These are cylindrical granules made from wood waste (shavings, sawdust, bark). In some cases, such fuel is produced from peat or straw. It has high environmental performance and does not cause an allergic reaction in humans.

Pellets are used as fuel, which are granules consisting of wood waste: pressed wood debris, chips, shavings

How much does pellet fuel cost? The price for these granules is determined depending on the quality and environmental performance. Today, 1 kg of pellets can be purchased at a price of 6.6 to 9.7 rubles. Accordingly, it is not difficult to calculate and determine how much 1 ton of such raw materials will cost.

The main difference between pellet boilers and conventional solid fuel devices is the ability to fully automate the work process. Thus, pellet structures are able to function with minimal human intervention.

Helpful information! Fuel pellets can easily deteriorate in a damp room, so they must be stored in a dry place only.

Advantages and disadvantages of a pellet stove

Today pellet units are the main competitors of gas heating equipment. Consider the advantages of using boilers operating on solid fuel pellets:

  • high efficiency (up to 97%);
Important advantages of pellet boilers are its small size, operational reliability and ease of maintenance.

Important advantages of pellet boilers are its small size, operational reliability and ease of maintenance.

  • the operation of such furnaces is completely safe due to their high environmental performance;
  • solid fuel water heaters of other types do not have such a burning time;
  • they are unpretentious in maintenance and have a high level of automation;
  • can be equipped with external temperature sensors;
  • the pellet unit can be controlled remotely, via a GSM module or a mobile application.

Like any other device, the pellet machine has some disadvantages. Consider them:

  • the cost of a unit of heat released during the processing of compressed wood pellets is quite high;
  • for the autonomous functioning of the boiler in a remote area outside the city, it is necessary to purchase a generator and additional technical equipment.

The cost of pellet raw materials per month is about 1 ton, which makes it easy to calculate the total cost of heating with such a solid fuel boiler. Forums on the Internet contain a lot of additional information about the features of use, as well as the pros and cons of such equipment.

Consumers are attracted by the relatively low cost of pellet boilers, the availability of fuel material and ease of maintenance, due to the automation of the heating process

Varieties of pellet boilers

First of all, today you can find two types of pellet boilers, depending on the fuel used:

  • pellet itself;
  • combined.

For the operation of the first units, exclusively granular raw materials are used. Combined models can operate on both pellets and other fuels. For example, a very common variant of a boiler that processes sawdust.

Another important point is the design of the gas burner. Depending on the type of this element, the following types of ovens are distinguished:

  • flare;
  • retorn.

Helpful information! Retard burners are used in units that function by processing only pellets, while flare burners are used in combined designs.

Depending on the model, pellet boilers can operate in fully automatic, semi-automatic or mechanical mode

It should also be noted that the supply of fuel to the bunker can be different. Depending on this, the following types of boilers are distinguished:

  • automatic;
  • partially automatic or semi-automatic;
  • mechanical.

The operation of pellet boilers with automatic feeding is regulated by programming the boilers by specialists. In the second case, the oven requires manual adjustment. And mechanical feeding means manual delivery of pellets to the hopper of the heating unit.

The choice of pellet boilers with a water circuit or other models depends on the specific case. It is recommended that you consider your local climate before purchasing this device. It is also advisable to go to several specialized forums and read reviews. A pellet boiler can be an excellent option for heating in a non-gasified region, however, its choice must be approached with special care.

Features of the device of the pellet stove

The unit, operating on fuel pellets, includes three main sections:

  • furnace;
  • convective;
  • ash pan.

Furnace department. It is represented by a chamber in which solid fuel pellets are burned. It is equipped with a flare or retor gas burner and has two doors (inspection and cleaning).

Convective department. Has a built-in heat exchanger. Depending on the location, there are three types of heat exchangers: vertical, horizontal, and combined.In this section, the heat carrier (water) is heated with hot air, which is released during the processing of fuel pellets. The design of the heat exchanger can be either tubular or plate.

Pellet boilers in most cases are used only for heating purposes and have one circuit. However, there are units on the market with two circuits: heating and water heating.

Ash pan. This section of the stove is necessary for collecting waste generated during the processing of pellets. After that, they are removed through the cleaning door.

The above structural elements of a pellet solid fuel boiler

represent the main part of it. But for the operation of the furnace, another important component is needed, namely: the APT attachment (automatic fuel supply).

Consider what devices are included in the APT set-top box:

  • bunker;
  • screw;
  • fan.

A hopper is a metal tank into which fuel is filled for processing. From this container, the fuel flows in parts to the combustion section. Depending on the location, there are two types of bunkers: internal (built-in) and external. The auger is an important element of the ADF and is required for batch feeding of pellets It is driven by a special device - a gearbox.

Where can you buy pellet boilers? Tips for choosing

Furnaces that operate on pellets can be purchased at a specialized store or ordered via the Internet. The modern boiler market offers a huge selection of various models, both domestic and foreign. Before purchasing this unit, experts recommend paying attention to the following parameters:

  • power;
  • Efficiency;
  • type of heat exchanger;
  • number of contours;
  • bunker volume;
  • fuel supply;
  • additional functions.
The first thing you should pay attention to when choosing is the power of the pellet boiler, it must exceed the nominal value by 10%

The first thing you should pay attention to when choosing is the power of the pellet boiler, it must exceed the nominal value by 10%

Depending on the power of the pellet unit, they are divided into household and industrial. The models used for heating residential buildings can have different powers (starting from 15 kW). The power is calculated as follows: heating 1 m² requires at least 1 kW of electricity. The efficiency of various models of pellet boilers ranges from 85 to 97%. There is a direct dependence of this indicator on the quality of the granular fuel.

Heat exchangers, which are equipped with pellet stoves, can be of two types:

  • cast iron;
  • steel.

Cast iron are distinguished by a long shelf life, as well as resistance to overheating. Of the minuses of the cast-iron device, one can single out the fact that it has a rather large mass and weak resistance to shock. In turn, steel models are more durable, however, they have a shorter operational life.

Today, only a small number of models from the entire range of boilers are equipped with hot water supply (DHW) circuits. To carry out heating of water, which will go to domestic needs, some structures are modernized with their own hands. Pellet boilers after improvement include additional storage tanks.
