Device Features
Breneran stoves, which have a high efficiency (80%), are characterized by the presence of two combustion chambers. In one of them, flammable waste is generated, which is completely destroyed in the second compartment. Temperature regulators installed on the door and chimney of the stove provide control over the heating rate and maintaining a stable temperature. The firebox channel has a limited length, so such a heater needs to be installed and heated only in one room.
In addition, Buleryan stoves are equipped with a blind damper, which must be slightly opened during the next filling of the firebox with several logs. After 2-3 minutes, the damper opens completely and the entire volume of firewood intended for one-time loading is placed in the oven. The gradual implementation of this procedure is explained by the need to comply with fire safety rules, if violated, backdraft will lead to the release of carbon monoxide into the steam room.
The furnace structure is enclosed in an outer cylindrical casing, on top of which a reservoir for heating water and a container for stones are installed. A specially equipped pipe on the stove connecting the compartment with cobblestones and the chimney helps to effectively use the heat generated by the heater. Due to the wooden borders, an obstacle is created for direct contact with the hot unit, which makes it impossible to get burns.
The bottom of the firebox is lined with a cast-iron grate, through which combustion products enter the ash box installed under the chambers.
How to choose a Breneran boiler
The manufacturer of air-heating furnaces of the Breneran brand, JSC Laotherm, produces a whole range of heat generators that differ in power and design features. For ease of selection, all gas generating equipment is divided into the AOT series.
The line includes models for domestic and industrial operating conditions, operating on almost any type of solid fuel: firewood, pellets, wood and paper industry waste, with the exception of coking coal.
Model range of heating boilers Breneran
The model range of JSC Laotherm includes six basic modifications of the Breneran stove. When choosing a suitable heat generator, you should focus on the equipment characteristics specified by the manufacturer in the technical documentation:
- AOT 19 – the design contains 8 pairs of convection pipes. Furnace power 35 kW. The model copes with heating rooms with a volume of 1000 m³. The total weight of the structure without firewood is 240 kg. The firebox can be loaded with fuel up to 200 kg. The Breneran wood-fired gas-fired heating stove, long-burning AOT 19, is optimally suited for heating a residential building with several floors and rooms.
AOT 16 is another productive stove, suitable for heating rooms up to 600 m³. The weight of the structure with an empty combustion chamber reaches 190 kg, which during installation will require the manufacture of a foundation. The model is optimally suited for industrial purposes. Based on the Breneran AOT 16 stove, air heating is installed for several rooms isolated from each other.
AOT 14 – the series includes two types of equipment, differing in the presence of a glass door made of heat-resistant glass. The model with glass is designed for installation under brickwork, imitation under a fireplace or Russian stove. The maximum performance is 18 kW, which is more than enough to fully heat rooms with 180 m² or a volume of up to 400 m³.
AOT 11 - starting with this series, the manufacturer Laotherm offers stoves that are more adapted for domestic rather than industrial conditions. The small dimensions of the boiler made it possible to reduce its weight to 100 kg, while maintaining high productivity of 11 kW. The stove can handle heating one large room or hall with a volume of 200 m³. By installing an air duct system for individual rooms, the AOT 11 boiler is capable of heating an entire house with an area of about 100 m².
AOT 08 is a small, dimensional, but at the same time productive stove, optimally suitable for heating unheated premises: dachas, garages, greenhouses. The weight of the structure, with the combustion chamber empty, is only 70 kg. For improved circulation of heated air, there are 7 convection channels on the body. The series offers models with and without glass doors. Maximum productivity 8 kW, heated room volume 140 m³.
AOT 06 – long-burning domestic solid fuel air-heating boilers using Breneran AOT 16 wood, designed for efficient and fast heating of rooms with a total volume of up to 100 m³. The model is successfully used for heating individual rooms. The stove's power is not enough to connect the air duct system. The series includes models with glass and all-metal doors.
For the convenience of consumers, the Laotherm company lists the standard sizes of furnaces in the full names of the models, from 01 to 04. This parameter affects the number of convection pipes and the dimensions of the structure.
Cost of Breneran stoves
Prices for Breneran solid fuel pyrolysis heating boilers make the purchase of such equipment affordable for almost any category of the population. What affects the cost of a boiler?
- Performance - the most powerful model AOT 19, will cost about 38 thousand rubles, a small household heat generator only 10,400 rubles.
The presence of a fire door with a glass insert - this function is provided in models AOT 06, 08, 11 and 14. The presence of an insert increases the cost of the design by approximately 1000 - 1500 rubles.
The stove manufacturer specifically maintains the same price for stoves in all company stores to reduce the likelihood of purchasing a surrogate. According to representatives of Laotherm, the stove at a lower cost is a fake.
Strengths and weaknesses of Buleryan stoves
A fairly simple design is characterized by low weight (95-120 kg), good transportability and ease of use. In addition, other advantages of such stoves are noted. Among them are the following:
- The durability of the unit is ensured by the material of its manufacture, namely heat-resistant steel, and the anti-corrosion coating of the housing.
- Soft steam, which allows you to take bath procedures, is formed due to the strong heating of the stones.
- The environmental side of using the device is due to the natural nature of this type of fuel, such as wood, which in no way can harm either human health or the environment.
- Ease of installation is ensured by simply installing the finished product and connecting it to a pre-equipped smoke exhaust system through a chimney.
- Excessive ultraviolet radiation entering the steam room from a heated metal firebox is shielded by a convection casing.
Among the disadvantages of Breneran stoves for baths, it is worth noting the following:
- Water tanks have a small capacity - only 30 liters.
- To collect condensate, a sealed container is required, which is not included with the oven. Liquid accumulation occurs in an unsealed plug glass, where moisture enters from the chimney.
Review of the model range of Buleryan stoves for baths
Models AOT-8 and AOT-12 represent the “Breneran” family of heating devices for steam rooms. There are modifications equipped with a glass or solid metal door. An extended remote firebox allows you to light the stove from the room adjacent to the steam room. The Breneran unit may include a mounted water tank with a capacity of 25 liters and a heat exchanger to which such a tank will be connected.
Installation of the furnace
To ensure the stability of the Buleryan bathhouse device and prevent its displacement under the influence of any mechanical factors, it is proposed to build a foundation. This structure provides protection for the lower part of the structure from damp and cold soil.
To construct the base, three piles are concreted into the floor of the bathhouse, each of which has a length of 1700 mm and a diameter of 200 mm. Then a slab is taken, the dimensions of which are approximately 1000x1400x200 mm, and combined with the grillage lintel. To strengthen the foundation, a mesh of reinforcing bars with a diameter of 10 mm and a dimensional pitch of 150x150 mm is used. If all actions are performed correctly, the slab will be laid 25 cm below the finished floor level. To hold it and reinforce it, it is necessary to make several dozen holes into which reinforcement rods are glued. Suspended formwork is removed immediately after the concrete mixture has hardened.
Installation of the Buleryan stove for a bath requires compliance with the following safety rules:
- The device should not be installed near the wall of the room, but at a distance of at least one meter. It is allowed to reduce this gap by 20 cm if the wall is finished with a two-centimeter layer of plaster.
- This requirement also applies to all flammable objects and structures that may be within the range of the heating device. Therefore, it is important to ensure that there is a free zone in front of the stove itself. The distance to the nearest object must be at least 1.2 m.
- Even in the case when the Buleryan sauna stove is installed on a specially constructed foundation, it is necessary to place a fire-resistant gasket under it. Along the edges of the span it is necessary to build screen protection or brickwork.
- Before installing the Breneran stove in the steam room, you should test the device outdoors. With the help of the first kindling, all technical oils used to process the body in production evaporate, releasing a small amount of acrid smoke and an unpleasant odor. Thus, the protective layer of paint undergoes final polymerization. The next time you use the unit, the negative phenomena will no longer be so noticeable, and will soon disappear altogether.
To ensure full draft, when installing the chimney, it should be aligned perpendicular to the stove foundation. To construct a chimney, a metal or ceramic pipe, stone or brickwork, or specially strong concrete blocks are usually used.
It is important that the outer end of the chimney protrudes at least half a meter above the ridge of the bathhouse roof.
The figures below show installation diagrams for the Breneran stove depending on the type of chimney.
Judging by the original design of the Buleryan stove, we can assume that it was invented by fairly experienced engineers. And the idea that this is an invention of Canadian handymen is most likely a myth. The history of buleryan begins in Canada, where it was invented to heat the cabins of woodcutters in harsh winter conditions. Correcting the operation of this unit does not require special skills and abilities. A person who has undergone initial training can easily handle its maintenance. This type of heating device is high-tech, does not contain electrical connections (this is not unimportant when working in harsh climatic conditions) and automatic elements, its base consists of inexpensive alloys, and accordingly its price is not high.

A little history and advantages of the stove
Wood cutters wandering through the harsh taiga needed heating equipment that could heat their cabins in a very short period of time. In addition, the stove must be transportable and lightweight, the fuel used in it must not be expensive. It was all these special requirements that were embodied in the design of Buleryan stoves:
- they are able to warm up a room with a volume of 25-30 cubic meters in 20 minutes,
- stoves can be heated with branches, wood chips, driftwood, peat or briquettes,
- On one load of fuel, the stove can operate for about 8 hours, i.e. owners may not bother with constant monitoring of the presence of firewood in the firebox,
- When the weather changes, the oven power can be adjusted.
Manufacturing a stove does not require the use of expensive materials and complex components - it can be manufactured by specialists working in any mechanical workshop.
In operation, Buleryan stoves show themselves to be very reliable devices in terms of safety:
- in any operating mode they do not produce carbon monoxide,
- the outer side of the stove body has a temperature of no higher than 60-70 degrees - accidental touching the stove will not lead to serious burns.
Buleryan wood stove, its structure, operating principle
It is not difficult to understand how units of this type work; they are based on the principle of controlled combustion, based on the fact that the fuel combustion process occurs in unique conditions, without free access to oxygen. Controlled air flow promotes the gas generation process. The carbon dioxide released in this case burns in the secondary afterburning chamber. An important point is the correct adjustment of the air damper - it allows you to achieve a significant increase in the efficiency of the stove.
The design of the Buleryan stove does not provide for the possibility of integrating a circuit for water circulation. Heating of the room occurs due to the circulation of air masses in steel pipes that surround the combustion chamber. Air circulation leads to the random entry of cooled air located at the bottom of the room and its exit, already sufficiently heated, through the air ducts, i.e. the convection process occurs.
The greatest effect from using such a unit is when heating a large room without internal partitions. To obtain high-quality heating of several rooms in a bathhouse, additional installation of devices for forced circulation of hot air between rooms will be required.
When installing such stoves in houses built of wood, in particular in sauna houses, it is imperative to comply with all fire safety rules.
Examining the classic design of the Buleryan stove, it should be noted that it is not suitable for heating bath stones. Therefore, despite all the advantages, such stoves are installed to heat all rooms of the sauna house, except for the steam room. Installing a furnace of this type will not require the construction of an additional ventilation system. The presence of a combustion control system allows you to make settings that are optimal in terms of economy and cleanliness.
To lay the air ducts and install the pressure equipment correctly, it is best to consult with a specialist. It should be remembered that only fulfillment of each of the installation conditions can ensure trouble-free operation of heating equipment.
Buleryan stoves for baths
A special type of Buleryan stove, intended for installation in a steam room, has an original modified body design: its upper part accommodates a tray for laying stones and a removable tank for heating water. For more active heating of the stones, a chimney outlet is provided from a compartment designed to accommodate these “heat accumulators”.
The Buleryan sauna stove can be operated in two modes: Russian bath and sauna. To switch to another operating mode, you will need to use the mode switch located near the fuel loading door.
When switching to the “sauna” position, the valve will be retracted and will supply fresh air through the blower into the compartment with hot stones, the air will warm up and dry, and it will enter the steam room in the form of dry heat.
When switching to the “Russian bath”, the valve will close the compartment with the stones, and the room will be heated only by the cobblestones located in the upper rows. To obtain wet steam, water the stones located near the chimney from a special ladle with a long handle - they have the highest temperature.
The Buleryan sauna stove is also equipped with:
- a wooden limiter designed to protect people from accidental contact with hot stones,
- thirty-liter stainless steel water tank.
Buleryan sauna stoves operate on paper and wood waste, peat or briquettes, and firewood. Experts do not recommend using coal or oak wood as fuel - they can cause the firebox to burn out.
The ideal temperature in the sauna is reached within 50 minutes after ignition.
The production capacities of the furnace can be as follows:
- small buleryan - used for steam room capacity up to 15 cubic meters, 75 kg of stones can be loaded into it, unit weight - 95 kg,
- large buleryan - installed in rooms with a volume of up to 25 cubic meters, weight of loaded stones - 100 kg, stove weight - 120 kg.
Installation rules and fire safety requirements
There are no special requirements for the installation of a heating unit, and therefore, no recommendations for its implementation. You will need to select a suitable location and connect the stove to the smoke removal system.
If we talk about the installation rules in a sauna house (or living space), then you should remember that installation will definitely require a fire-resistant base, for example, a metal one.
The recommended chimney height is more than 3 m; this rule must be observed. To increase operating efficiency, you will need to connect the air ducts and outlets of furnace convectors.
The main task during installation is compliance with all fire safety standards. The recommended distance from the wall to the body is more than 1 m, or 0.8 m if the wall is covered with a thick layer of plaster. There should be a free space in front of the stove with a depth of less than 1.2 m.
If the stove is installed in a wall, then it will be necessary to cover the edges of the span with metal sheets or finish it with bricks.
The stove should be heated with wood chips or paper placed in the firebox; the ash pan is pulled out 1.5 cm to create draft; when the wood chips flare up, a portion of firewood is loaded into the chamber and the door is closed tightly.
Buleryan stove in the interior of a sauna house
If the size of the relaxation room in the sauna house allows, then the installation can be performed in a portal specially constructed for it. It may look like a regular oven. In this case, special bricks can be used as a finishing material. When finishing with brick, you should remember the need to ensure air flow to the unit.
Decoration is carried out not only in order to increase the attractiveness of the heating device, but also to increase the safety of people visiting the bathhouse.
Do-it-yourself Buleryan stoves
In principle, it will be easier to purchase buleryan. You can buy ready-made Buleryan stoves for relatively little money - 200 - 250 dollars. In cases where it is possible to work with a machine that allows you to make the necessary parts, the availability of a sufficient amount of time and certain raw materials - producing this type of stove with your own hands is quite cost-effective and justified. For its manufacture, you can use metal of any quality, the total costs in this case will be significantly reduced.

Adjusting modes
Using the switch, which functions for the “Russian bath” and “Finnish sauna” modes, you can adjust the heating temperature and humidity level in the steam room. This device is located near the door through which firewood is supplied to the firebox.
Switching modes occurs according to the following principle:
- If it is necessary to create a dry sauna atmosphere in the steam room, the valve of the device opens, allowing cold air to pass through. The air flow moves through the pipes and, already heated, enters the heater. The temperature of the stones increases, which warms the surrounding space and dries out the air in the room.
- If you want to have a good steam in a bathhouse with a broom, you need to close the valve tightly. Thus, air access is blocked and the heater is heated from the hot stove body. To create wet steam, the stones are poured with liquid.
Almost always, the Buleryan heating device for a bath includes a water tank installed on top of the structure. The liquid heated in it is usually used for washing. Wooden strips connected to each other serve as protection against contact between a person and the hot stove body.
Operational moments
When starting the Breneran unit, you need to slightly open the vent and carefully burn a small amount of paper or wood chips in the firebox. After the flame burns, you can add firewood. Until the required temperature is established in the steam room, the oven will operate continuously. In just 45 minutes the room will warm up to 100 °C. Then you can cover all the holes through which oxygen enters the firebox. This reduces the intensity of the flame in the fuel combustion device, but the stove is already so hot that the heat emanating from it heats the water and stones. When the cobblestones are heated sufficiently, the steam room receives a high temperature that can last up to two hours.
Operational Features
The safety and efficiency of the Buleryan stove depend not only on the accuracy of assembly, but also on correct operation. The following guidelines should be considered when using this installation.
- The stove should be heated only with firewood or wood waste (sawdust, paper). The unit is not designed for any type of coal or liquid fuel.
- The stove should be ignited using paper or wood chips (splints) with a gradual loading of logs, starting with a small size. At the moment of ignition, the blower should be pulled out 2–3 cm.
- First stage: active burning of wood lasts about 35–45 minutes, until the desired temperature is reached. During this period, the ash pan opens, providing air oxygen to support combustion. Next, the ash pan slides in and the ash pan closes to stop active combustion and switch to smoldering mode. At the same time, the draft is adjusted using the chimney damper.
Wood of any species and fairly large logs can be used as fuel for the Buleryan stove. It is recommended to stir hardwood firewood only occasionally. If you use the steam room for a long time, you can carry out a fuel report. To do this, you need to open the door slowly, and first open the blower
It is important that smoke does not penetrate into the room during laying. It should also be remembered that in bath conditions these stoves should operate continuously for no more than 7–8 hours
