Pellet boilers: prices and characteristics of models

Pellet boilers: prices and characteristics of models from different manufacturers

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

Pellet boilers have appeared on the market for a long time and have already established themselves as highly efficient heating systems

What is a pellet boiler?

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

Pellets are used as fuel, which are pellets consisting of wood waste: pressed wood fragments, chips, shavings

How much does pellet fuel cost? The price of these pellets is determined depending on the quality and environmental indicators. To date, 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 possibility of full automation of the workflow. Thus, pellet structures are able to function with minimal human intervention.

Useful information! Fuel pellets can easily deteriorate in a room with a high humidity level, so they must be stored exclusively in a dry place.

Advantages and disadvantages of a pellet oven

To date, 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, reliability during operation and ease of maintenance

• the operation of such furnaces is completely safe due to high environmental performance;
• solid-fuel water heaters of other types do not have such a gorenje duration;
• they are unpretentious in maintenance and have a high level of automation;
• they can be equipped with remote sensors that determine the temperature;
• 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 operation of the boiler at a remote site located 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:

• actually pellets;
• combined.

For the operation of the first units, only granular raw materials are used. And combined models can function both on pellets and on 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 furnaces are distinguished:

• torchlight;
• retort.

Useful information! Retort burners are used in units that function by processing only pellets, and flare burners are used in combined designs.

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

And it is also worth noting that the supply of fuel raw materials 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 boilers by specialists. In the second case, the oven requires manual adjustment. And mechanical feeding implies 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. Before purchasing this device, it is recommended to take into account the peculiarities of the climate in your region. And 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 should be approached with special care.

Features of the pellet furnace device

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

• furnace;
• convective;
• ashtray.

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

Convective department. It has a built-in heat exchanger. Depending on the location, there are three types of heat exchangers: vertical, horizontal, and combined. In this department, the coolant (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 lamellar.

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.

Standard pellet boiler design

Ashtray. This section of the furnace is necessary for the collection of waste that is formed during the processing of pellets. After that, they are removed through the cleaning door.

The above-mentioned 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 prefix (automatic fuel supply).

Let’s consider which devices are part of the APT set-top box:

• bunker;
• auger;
• fan.

A bunker is a metal tank into which fuel is filled for processing. From this tank, the fuel enters the furnace department in parts. Depending on the location, there are two types of bunkers: internal (built-in) and external. The auger is an important element of the APT and is necessary for the batch feeding of pellets. It is driven by a special gear unit.

Where can I buy pellet boilers? Tips for choosing

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

• power;
• EFFICIENCY;
• type of heat exchanger;
• number of contours;
• hopper volume;
• fuel supply;
• additional functions.

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

Depending on the capacity of the pellet unit, they are divided into domestic and industrial. Models used for heating residential buildings can have different power (starting from 15 kW). The power calculation is performed as follows: at least 1 kW of electricity is required for heating 1 m2. 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 granular fuel.

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

• cast iron;
• steel.

Cast iron has a long shelf life, as well as resistance to overheating. Of the disadvantages of the cast-iron device, it can be distinguished that it has a rather large mass and weak resistance to shocks. In turn, steel models are more durable, however, they have a shorter service life.

To date, only a small number of models from the entire range of boilers are equipped with hot water supply circuits (DHW). To carry out the heating of water, which will be used for household needs, some structures are upgraded with their own hands. Pellet boilers after improvement include additional storage tanks.

The control of the pellet boiler consists in dosing and feeding fuel into the combustion chamber

The volume of the hopper is an individual indicator, which depends on the specifics of using the boiler and the needs of the consumer. Pellets can be delivered to the fuel compartment in two ways:

• using a screw;
• vacuum feeding.

Vacuum feeding is more efficient and differs in that it has a low noise level.

Additional functions are needed to increase the efficiency of using the boiler, as well as for convenience. These include:

• GSM module;
• automatic ignition;
• self-cleaning;
• temperature sensors.

The self-cleaning system is very popular, as it requires minimal human intervention. A boiler with such a system should be checked no more than 1 time per month.

Pay attention! The average cost of pellets is 8,000 rubles per 1 ton. Biofuel costs are determined taking into account the individual operational characteristics of the equipment and the needs of the owners.

For successful operation and maintenance, the pellet boiler requires installation in a fairly spacious room that meets a number of requirements

Before purchasing this unit, experts recommend studying reviews on the Internet. Pellet boilers of the same model can be produced in different configurations, which also needs to be remembered before buying.
