The best long burning boiler for the home. The best Russian-made solid fuel boiler

Traditional heating stoves have been replaced by wood-fired boilers. domestic production. The main advantage of wood-fired boilers made in Russia is unpretentiousness to the quality of the fuel used and operating conditions, low cost (compared to European units).

Wood boiler manufacturers in Russia

The domestic consumer has already been able to form a definite opinion about household and industrial solid fuel boilers for wood, Russian production. Like any other heating equipment, the products have their advantages and disadvantages.

Types of wood-burning heating boilers manufactured in Russia can be divided into several classes:

According to the principle of work.
The presence of a DHW circuit.
Destiny.
type of heat exchanger.

On the this moment, the consumer is offered traditional and gas generating models, with a built-in hot water circuit or the ability to connect an indirect heating boiler.

We offer domestic boilers for firewood of the following designs:

Russian-made gas-fired wood-burning boilers. For a long time, the manufacture of this type of equipment was the prerogative of exclusively European companies.
At the moment, wood pyrolysis boilers long burning domestic production, are offered by several companies at once. The advantage of "our" equipment is the reduced consumption of firewood and longer work from one tab.
Boilers with a conventional design - heat generators of this type, according to the principle of operation, resemble a conventional wood-burning stove. The difference is the complete set of the structure with a water circuit. It is allowed to connect to a conventional radiator heating network with or coolant.

In addition to the design features and the principle of operation used, when choosing our wood-fired boiler, they are guided by the manufacturer's company. Not every factory produces products of the same quality and reliability. When choosing a boiler, it will not be superfluous to study real reviews customers who have been using the equipment for some time.

Which domestic wood-fired boiler to choose

Russian-made wood-fired hot water heating boilers are offered by more than a dozen different manufacturers. Judging by customer reviews, the products of the following companies are especially popular:

Modern water heating boilers on firewood of Russian production, in terms of their characteristics they are in no way inferior to Western counterparts. The design uses new technologies that ensure the autonomy of the heat generator and a high degree of safety. Automation controls the heating of the coolant.

Many models use backup source heat, which is very convenient when heating with wood. When the fire in the furnace dies out, the electric heating element turns on and continues to heat the coolant, preventing the house from cooling down.

At Russian enterprises, steel boilers are mainly manufactured, but a series of equipment with cast-iron heat exchangers and high performance can be distinguished separately (KChM plant). Models are intended for domestic use.

Wood boilers of high power, for industrial purposes, of all the above manufacturers, are manufactured only by KZKO LLC.

The cost of Russian wood boilers

The cost of domestic wood heating equipment, approximately 2-3 times less than European counterparts, which explains its demand among consumers. The price is affected by the equipment configuration, the type of heat exchanger and the brand of equipment.

For example, below is the cost of units, depending on the manufacturer, of approximately the same power and identical parameters. Productivity from 15-20 kW.

PARTNER (Bonfire) - boilers of small power, 16 and 20 kW, will cost 21,960 and 24,990 thousand rubles. respectively.
DON (Conord) - the price, for a heat generator similar to the previous one, varies between 24-28 thousand rubles, depending on the configuration.
Stoker Aqua (Ermak) will cost only 20 thousand rubles, provided that it is equipped with an electric heating element.
KCHM (Kirov Plant) - the highest cost of boilers among analogues of this class is due to the presence of a cast-iron heat exchanger. A 21 kW heat generator will cost about 44 thousand rubles, in the basic configuration.
The geyser is one of the most reliable heating boilers on the domestic market. The cost of pyrolysis equipment varies between 44-48 thousand rubles.
Zota - equipment, in terms of quality and automation of boilers, as close as possible to European units. The cost of a 20 kW boiler will be about 33 thousand rubles.

Price policy domestic manufacturers takes into account the fact that the produced units are somewhat inferior in quality to their foreign counterparts.

Given the fact that gas and electricity are relatively expensive "heat carriers", people often resort to solid fuel boilers. They are a good and effective solution for heating a private house or cottage. Such devices are indispensable in places where gas is not supplied.

In this review, we will present best models boilers that run on wood (including wood briquettes) and coal (and coal briquettes). When compiling the rating, we were guided by customer reviews.

1st place - Stropuva Mini S8 (51,000 rubles)

The best solid fuel boiler is Stropuva Mini S8. It is efficient, compact (small barrel), with high efficiency. True, and the price is right.

Characteristics:

One circuit (that is, it provides only heating in the house);
Power 8 kW (suitable for a house up to 80 square meters);
Fuel used: firewood and briquettes;
Installed on the floor;
Heat carrier temperature: 60-95 С;
From protection: only a safety valve.
The model received first place in the ranking of long-burning boilers. The review lies.

It is worth noting that the device is positioned as a long-burning solid fuel boiler, and this is true - the fuel inside burns for a long time (sometimes up to 20 hours). So there is little consumption. Assembly - on highest level: the door handles are reliable, the device is heavy and seems to be monolithic. There are no problems in installation and operation, although the two of them will not be able to cope with the installation (due to the weight of 130 kg).

Definitely one of the best wood burning boilers with simple design and long burning time. It is reliable, because there is almost nothing to break, and most importantly - compact. True, it is only suitable for small house or cottages. Recommended!

The high cost of operating gas-fired heating equipment and the inaccessibility of this type of energy carrier for small settlements lead to an increase in the popularity of solid fuel boilers.

The use of coal and firewood is becoming an excellent alternative to gas. However huge assortment equipment models delivers certain difficulties when choosing.

In order to decide which boiler is best to purchase for specific conditions, it is worth conducting comparative analysis. That is, taking equipment similar in performance, consider several models different manufacturers. So, for example, each of the boilers of the proposed TOP review can be used to heat rooms with a total area of about 200 square meters. m and has its own advantages.

At the same time, it has a quite attractive appearance due to the coloring of the case with heat-resistant red enamel.

Advantages and disadvantages

The main advantages of the boiler are its high efficiency and fuel economy. You can load firewood into the firebox no more than 2 times a day. At the same time, the equipment is able to serve for a long time without succumbing to deformation and corrosion, thanks to the use of cast iron in the manufacture of both the furnace and the heat exchanger.

Among the shortcomings of the equipment, it is worth noting the not very convenient cleaning and the need to adapt to the features of traction control. When loading firewood, the furnace door interferes a little. And moving the Beaver 20 DLO is harder than a number of analogues due to its relatively large mass.

Mounting Features

Installation of the boiler is possible both in residential premises and in utility rooms (corridors, basements, boiler rooms). In this case, it is necessary to provide an inflow of air for combustion and a system for removing combustion products. In addition, for safe work The equipment must be installed on a non-combustible base. The installation of the boiler must be carried out by specialized organizations that have the appropriate permission.

Description

The G221-25 boiler is completely autonomous, and its operation does not depend on power surges, or on gas or electricity cuts. It is equipped open cam combustion, which implies the intake of air directly from the room and the removal of flue gases due to the draft of a vertical chimney.

The operating time of the equipment on one tab of fuel reaches several hours - it can be increased by switching to an economical mode of operation or by additionally installing a loading hopper. And due to the stylish coloring with heat-resistant blue enamel, the new generation boiler looks great in the interior of any room where it is installed.

Advantages and disadvantages

The main advantages of the model include increased corrosion resistance of the material of the body and heat exchanger (cast iron), ease of operation and increased dimensions of the furnace. In addition, for ease of use, the firebox door can be hung on both the left and right sides. And the disadvantages of the model can only be called a significant weight (310 kg) and high cost.

Installation nuances

The boiler can be installed both separately and together with other types of heating equipment (gas, liquid fuel or electric) in residential, domestic and industrial premises. And Buderus Logano G221-25 can be used both in pumping and gravity water heating systems.

The equipment can be mounted independently, even without performing welding work. However, due to the need to comply with a number of rules, this is not recommended. And the installation should be carried out by qualified specialists familiar with the process of installing solid fuel boilers in heating systems.

Basic properties of the model

The equipment has a modern stylish appearance, which is emphasized by the red color of the body. The door of a fire chamber of a copper is completed with the convenient handle increasing reliability of opening and closing. This model takes air from the room, and removes it into the atmosphere through a vertical chimney.

Due to the design features, Bourgeois-K Modern-24 can operate for several hours after one load. Although with the help of a regulator of air supply to the furnace, a high-speed heating mode is also provided, which allows you to quickly heat a cold room.

Pros and cons

The main advantages of the boiler, according to user reviews, are the economical use of firewood - about half as much as other solid fuel boilers. For heating the maximum possible area served by the boiler, no more than 40 kg of firewood per day is required. It is also worth noting the complete independence of the equipment from energy sources such as gas or electricity, and compact dimensions that allow you to install the device in any convenient and suitable place for this.

However, Modern-24 also has drawbacks. For example, the need to install a pipe with a height of at least 8 meters for the normal removal of combustion products. And the equipment grate burns out too quickly and needs to be replaced. In addition, according to the owners of the boilers, sometimes the gates of the appliances clog too quickly.

Installation Features

The boiler and its associated equipment must only be installed by professionals in accordance with the design documentation and current installation regulations. They must also ensure the start-up of the device and its repair in case of malfunctions. Premises for the installation of boilers should be provided with a sufficient amount of light, if necessary, equip with good artificial lighting.

Model description

Traditionally dyed Blue colour heat-resistant enamel (which, thanks to its anti-corrosion properties, will last no less than the boiler itself, that is, about 15 years), has an attractive appearance and is able to decorate a residential, domestic, and even utility room. The cast iron body of this model is strong enough to provide high degree fire safety, and high heat transfer guarantees comfortable temperature conditions in the house throughout the cold period of time.

A long process of burning logs in the boiler furnace is obtained with the help of a special regulator that increases or decreases the air flow. Due to this, equipment that can be used both in pressure and gravity heating systems can work for several hours on one portion of firewood. Together with it, it is allowed to include equipment on other types of energy carriers in the water heating system - gas, electricity and even liquid fuel. To do this, the boiler is equipped with a large receiving hopper, designed for loading large logs.

Advantages and disadvantages

The boiler has many advantages. These include the minimum time for heating the surrounding air and an attractive appearance. And when equipped with a bunker, the equipment copes well with almost semi-autonomous operation, that is, it can heat rooms, almost without requiring the presence of a person.

But as standard, the boiler cools down quickly regardless of the mode, as evidenced by customer reviews who have already used the Buderus Logano G221-20. In addition, the equipment is too expensive compared to its functionality. And during operation in a water heating system, the boiler is best supplemented with other heating equipment, for example, running on gas or electricity.

Mounting

When installing this Logano model, there is no need to use welding - it is quite simple to connect to an existing heating system using conventional tools. True, in this case, a number of recommendations should be followed, which only an experienced specialist can handle. After connecting and putting the equipment into operation, the user is required to comply with a number of rules:

do not change the design of the smoke exhaust system;
do not start the boiler without enough water;
use only permitted types of fuel;
do not downsize ventilation holes in room.

Price

Many buyers who choose heating equipment note the high cost of G221-20. The minimum amount that will have to be paid for it is 70,600 rubles. However, there are offers on the market and much more expensive - up to 104 thousand rubles.

Main characteristics:

maximum area of heated premises: 150 sq. m;
power control options: within 30–100%;
thermal efficiency of the model: up to 83%;
the use of fuels such as coal, wood, wood waste or pellets;
built-in electrical equipment: heating element with a power of 6 kW;
it is possible to install a gas or pellet burner;
maximum dimensions of firewood: diameter up to 100 mm, length up to 500 mm;
device dimensions: 74×34×50 cm;
gross weight without laying firewood: 98 kg.

Model description

The compact dimensions and appearance of the equipment contribute to its placement in any room of a residential building or domestic premises. At the same time, the boiler is quite powerful and efficient due to the presence of a heat exchanger and the possibility of completely extinguishing the flame in the tube sheet. The time of its operation on wood can vary from 60–90 minutes to several hours, on which fuel economy depends.

If you install one of the pellet or gas burners produced by the same Teplodar brand, it is possible to ensure the operation of the boiler in the temporary absence of solid fuel. Also, the equipment is able to work on electricity, for which a 6-kilowatt heating element is already built into its design.

Pros and cons

The main advantage of the Kupper OK 15 is considered by most consumers to be its low cost, combined with decent quality. The efficiency of the heating device and its maintainability are also highly valued. Using the boiler, you can lay firewood in its firebox no more than 2 times a day. You can also use other types of energy carrier, the transition to which this model is quite simple.

The disadvantages include fuel consumption, markedly increased compared to other, more expensive solid fuel boilers of other brands. Another disadvantage of the model is its rather complicated installation.

Installation Features

Most boilers operating in a water heating system are relatively easy to install, and calling a specialist to install them is rather associated with the need for experience in such work. However, for the installation of Kupper OK 15, you will have to turn to professionals also because of the complexity of its connection with pipes. In this case, you should be guided by the rules for connecting electrical power and PUE.

Price

The cost of the boiler from different suppliers can differ by almost one and a half times. The minimum price for equipment is 22,820 rubles. The maximum reaches 35210 rubles.

Content

When arranging an autonomous heat supply system, first of all, you should decide on the choice of energy carrier. If connection to the main gas is impossible or too expensive, solid fuel boilers are usually chosen for heating a private house. Such units are reliable and quite economical to use. The model range includes non-volatile solid fuel boilers, which is relevant for areas with unstable power supply.

Solid fuel boiler for heating a private house

Main pros and cons

A solid fuel boiler for heating a house is a floor-standing unit with a heat exchanger made of cast iron or heat-resistant steel. The energy carrier is firewood, coal (brown, stone), peat briquettes, woodworking and crop production waste.

The list of advantages of such heat generators includes:

choice and availability of solid fuels;
low cost of thermal energy - 1 kW of heat generated by a solid fuel unit is cheaper than thermal energy obtained using boilers of a different type (4 times compared to gas, 8 times relative to liquid fuel and 17 times compared to using electricity);
maintainability;
ease of installation;
availability of non-volatile models that are suitable for operation in areas with undeveloped infrastructure;
no need to issue permits for installation.

Floor standing solid fuel boiler

When planning to buy a solid fuel heating unit for a country house, its disadvantages should also be taken into account:

the need to regularly add fuel (the duration of burning of one bookmark and the availability of automatic energy supply depends on the features of the model);
formation of non-combustible fuel residue (ash), emissions of flue gases into the atmosphere;
the need for regular cleaning of the chimney from soot (this improves traction and avoids the ignition of soot in the chimney, which can lead to a fire);
the risk of overheating and failure of the boiler unit - the operation of the equipment must be controlled;
relatively low efficiency;
the need to organize a place to store a large amount of fuel.

Criterias of choice

When deciding which solid fuel boiler to choose, one should proceed from the following factors:

fuel used (the most affordable fuel and its possible substitute are selected);
boiler type;
heat exchanger material (solid fuel cast iron models are durable, but heavy and sensitive to sudden temperature changes, steel units are lighter, but prone to corrosion under the influence of aggressive condensate and fail faster);
work efficiency - models with high efficiency are more economical;
the method and frequency of loading the energy carrier (fuel can be automatically supplied to the pellet boiler, the long-burning unit requires top loading, etc.);
the need for a boiler room (heating boilers with top loading should not be installed in the residential part of the house, as smoke will enter the room);
the presence of a second circuit for preparing water for the DHW system;
functionality of the unit (use of any wood and paper household waste as fuel, availability of hob etc.);
dimensions and ease of installation, the need for a separate foundation.

Solid fuel boiler and types of fuel

Having decided on the type and functional parameters of the boiler unit, it is required to select a model of suitable power. For general calculations, they proceed from the ratio of 1 kW per 10 square meters. m. area of the house. Thus, for a construction with a total area of 100 m2, a boiler with a capacity of at least 10 kW is required.

To use the energy carrier cost-effectively, choose a boiler based on an accurate thermal calculation of the house (it is recommended to insulate the building to reduce heat loss). It is important to provide for some power reserve so that the equipment does not work at the limit of its capabilities, quickly developing its operational resource. The power margin is especially important when using fuels whose calorific value is lower than the standard design parameters. The decrease in efficiency is the greater, the higher the moisture content of wood or peat.

To make the most of thermal energy solid fuel boiler and avoid the need to put firewood in the furnace at night, install a heat-insulated buffer tank with water - a heat accumulator. The liquid heated during the day automatically begins to flow into the heating circuit when the coolant in it begins to cool.

Types of solid fuel boilers

Before choosing a solid fuel boiler, it is advisable to familiarize yourself with the features of the units various types. Solid fuel heat generators for a private house are divided into the following types:

With manual fuel loading:
- traditional design;
- pyrolysis;
- long burning (with the top loading).
With automatic supply of energy carrier - pellet aggregates.

We select a model taking into account ease of operation and maintenance, economic efficiency equipment, heating boiler prices.

Traditional (classic) units

Traditional solid fuel boilers are the most popular option due to their simple design and affordable cost. The intensity of fuel combustion is controlled by a temperature sensor and an air damper, which changes its position depending on the operation of the sensor.

On one bookmark of fuel, the boiler is able to work for 2-6 hours. There are completely autonomous units that do not require power supply (suitable for gravity heating systems) and modified boilers with electronic sensors, remote system control, a fan for forced air supply to the furnace.

Traditional solid fuel heating unit

Advantages :

the ability to use any type of fuel - coal, briquettes, firewood, pellets, household waste (paper, branches, etc.);
simplicity and reliability;
simple binding;
affordable price.

Flaws :

it is required to load fuel into the boiler 4-8 times during the day;
adjustment temperature regime in a small range;
the high inertia of the boiler, especially the cast iron one, does not allow you to quickly change the degree of heating of the coolant.

Pyrolysis units

The pyrolysis boiler was invented relatively recently. The principle of operation is based on the fact that with a lack of oxygen, the fuel smolders with the release of combustible gases, and when wood gas is burned, a large number of thermal energy.

The pyrolysis boiler is equipped with two chambers - the first is designed for fuel, the second - for the afterburning of volatile substances. This is a unit with high efficiency and low emissions.

Types of pyrolysis heating units

Advantages :

Efficiency over 90%;
fuel (lignite, firewood, etc.) burns almost without residue, so frequent cleaning of equipment is not required;
it is enough to put fuel 2-4 times a day;
the pyrolysis boiler allows you to burn large-sized non-chopped firewood.

Flaws :

constructive complexity;
energy dependence;
high price;
demanding on the quality and quantity of fuel - the pyrolysis boiler loses efficiency by almost half when using wet fuel, half loading the chamber leads to tar settling inside the chimney.

Long burning units

The heating units of the new generation include long-burning boilers, in which the fuel burns from top to bottom. The heat generator can run on wood and other types of solid fuels, including coke, anthracite, brown coal, peat or sawdust briquettes, etc.

In the section, the upper combustion boiler is a hollow cylinder, in which up to 50 kg of fuel is placed. A special device is installed on top, distributing air, which, as the energy carrier burns, goes down. This design ensures slow combustion of the fuel (the combustion process is maintained in the upper 10-20 cm of the fuel) with the release of combustible gas, which is afterburned with a large release of heat. The intensity of the flame is regulated by supplying air through the upper opening with a damper.

Solid fuel burner

Advantages :

long burning time (depending on the selected fuel) - 12-48 hours if used coal– up to 7 days;
energy independence;
cleaning the unit from ash is required 2-3 times a month, and not daily, as is the case with a classic boiler;
more affordable cost compared to a pyrolysis heat generator (but higher than that of a classic one).

Flaws :

relatively low efficiency;
the inability to add fuel without waiting for the end of the combustion cycle;

It is also worth paying attention to the not very convenient maintenance of this solid fuel boiler for heating, since the fuel has to be laid from above. It is easy to pour coal or briquettes, but it is quite difficult to properly lay firewood.

Pellet heaters

Boilers for home heating, operating on granular fuel from wood waste (pellets), are as convenient as possible to operate. In terms of comfort of use, these are the best solid fuel boilers. They are fully automated - wood pellets enter the furnace from a bunker, the volume of which is designed for several days of operation.

Advantages :

full automation of fuel supply (replenishment is carried out as the pellets burn);
the possibility of fine adjustment of the heating of the coolant, the installation of weather-dependent automation, stable maintenance of the set temperature;
automatic ignition system;
Efficiency about 90%;
long service life (about 20 years).

Pellet machine with automatic fuel supply

Flaws :

volatility (require a stable power supply);
restriction on the choice of fuel (only pellets can be used);
high price.

The highest result of the development of technologies is pellet-type heating boilers, which can use coal as a fuel that automatically enters the combustion chamber. There are also models equipped with a special replacement mesh that allow you to burn dry wood in a pellet boiler.

Popular Models

When figuring out which solid fuel boiler is better, you should pay attention to the popular models of units of all types.
