The Breneran or Buleryan stove is a highly efficient small-sized heating device produced by Canadian, German and Russian companies. It vaguely resembles a classic potbelly stove, but has its own improved characteristics and high efficiency. Furnaces of this type are mass-produced; the model range differs in power and design. You can make a Breneran stove with your own hands. The choice of product depends on the area of the room and its purpose, the space allocated for the oven, the budget and the necessary functions.
Description of the Breneran furnace
Buleryan is a German company, Breneran stoves are manufactured under license. The
Buleryan stove is a development of the German company Bulerjan, which produces heating equipment. The name Breneran refers to the same devices, but created by Russian companies under license.
Characteristics:
- There is a flat platform at the top. Used to heat food.
- The shape is cubic instead of the usual cylindrical.
- There is an ash pan, as well as a grate.
- Convection heat exchangers are recessed into the housing.
Initially, the product was conceived as a stove with an air heat exchanger, but its feasibility is not justified. The heat capacity of such a device is low, which reduces the efficiency.
To preserve heat, owners use various storage devices for convection pipes. They can also be placed in brickwork, forming something like a fireplace. This is a version of the Breneran sauna stove.
The Breneran stove can be used for cooking, including
Currently, the Breneran boiler is actively used in the following areas:
- heating of cottages and houses;
- production workshops;
- garages;
- baths;
- cafes and restaurants;
- administrative buildings in small settlements.
When choosing and installing a boiler, power, dimensions, installation location and other parameters are taken into account. They affect the efficiency and uniformity of heating of the room.
Firewood, bark, wood chips, and shavings are used as fuel. It is not recommended to choose coal as a raw material in an original furnace, since the high temperature may cause deformation of the body. You can get around this ban by upgrading the device. It is necessary to make a collector at the bottom of the heat exchanger and supply air using a blower.
There are two varieties: a Breneran boiler with a water circuit and a Breneran gas generator stove. The first type operates from water heating of the house, and the second - from gas. Also, gas generating devices often have a place for cooking.
PVC installation
If in a country cottage it is planned to install water heating from a brick stove (wood-burning), the heat exchanger is designed individually, for a specific stove. Such a device is practically beyond repair, so for installation a specialist stove specialist is hired who can professionally perform all the work:
- Make a heat exchanger and double check its quality - before and after installation.
- Install the heat exchanger at the required stage (after completing the foundation), then continue laying, observing certain rules. When installing the heat exchanger, compensation gaps are left, leaving 1-1.5 cm to the walls of the combustion chamber. Gaps that take into account thermal expansion are also needed when installing pipes.
- When installing a heat exchanger with pipes and for insulation, use only heat-resistant seals.

Design features and operating principle
Structural components of the Buleryan stove
The Breneran stove from Canadian specialists has a long-burning convection boiler design. They enlarged the combustion doors, made a different shape for the blower in the form of a pipe, and installed a throttle inside to regulate the air level. To control the power of the furnace, a lever is used that controls the throttle.
The firebox is a metal cylinder that has tubular heat exchangers on both sides. They are curved like knees. Due to the location of most of the pipe in the body of the stove, the air receives up to 70% of the heat from the wood. This allows air to be heated to 100°C at an oven temperature of 60°C.
The firebox is divided into three chambers. A grate or metal tray is installed in the lower part. A metal sheet is mounted under the arch of the firebox. Volatile compounds are burned out in the upper chamber.
Combustion products are discharged through a special hole in the afterburner chamber. At the beginning of the chimney there is a damper with a 90° sector. To select the correct rod, a gap is made around the metal plate that adjusts it. It is equal to 10-15% of the chimney diameter.
The original furnaces also have a device for pyrolysis combustion of gases - an economizer. It is installed near the outlet opening on the horizontal section of the chimney. In order for the combustion products to have time to cool, the pipe must have an optimal height.
Advantages and disadvantages
Firewood must be prepared in advance so that it is completely dry.
The positive aspects of Breneran include:
- Mobility. The product has compact dimensions, so it is convenient to transport.
- Compactness. The configuration of the furnace allows the device to be installed in small temporary buildings.
- Safety. This is achieved due to the tightness of the working chamber and the use of a single-door design. There are also obstacles to accidentally touching hot metal parts.
- High performance. The room is heated in the shortest possible time due to forced convection.
- Possibility of long-term operation. The Breneran sauna stove can operate for several hours on one load of fuel.
- Easy to use and highly reliable.
The disadvantages include achieving high productivity only when using completely dry firewood. Humidity more than 10% reduces combustion intensity and reduces efficiency. The oven also doesn't hold heat well. After the fuel burns out, the temperature in the room decreases. To improve operating efficiency, it is also important to provide additional thermal insulation to the chimney.
How to install it yourself
Installing it yourself is not so easy. The furnace, like all other metal furnaces, produces harsh thermal radiation. Therefore, it is necessary to adequately evaluate where exactly to place the stove so that there are no fire hazards. The average weight of a Breneran stove is 105 kilograms - this fact must be taken into account during transportation and installation.
There is no need for a monumental foundation for the Breneran furnace, but it is advisable to make it higher than the floor level to a maximum of 20 centimeters. Heating elements must be protected, as they are hot metal. For this stove, it is advisable to choose stainless steel pipes so that they last longer and are of better quality.
Oven operation and maintenance
Once a year, you need to clean the chimney so that the stove does not fill with smoke.
In order for the Breneran stove to work efficiently, it is necessary to comply with the operating conditions and properly maintain the heater.
Basic advice given by experts:
- You can only heat with dry, finely chopped wood. Place paper or cardboard under them.
- It is not recommended to preheat the oven for more than 30 minutes with the damper fully open. Breneran is designed for smoldering fuel, which can cause some of the thermal energy to escape.
- After the wood has completely burned out, the stove switches to gasification mode. To do this, you need to close the gate and throttle.
If the potbelly stove fills with smoke, one of the following errors can be judged:
- Low chimney height. Optimal performance is ensured by a pipe 5 meters high.
- The slide valve is closed.
- The smoke channel is clogged with soot. It needs to be cleaned. Preventive cleaning is carried out once a year.
Contamination of the furnace impairs its draft, which reduces heat transfer. For cleaning, you can seek help from specialists.
Basic recommendations
This stove operates due to the optimized fuel combustion process that occurs in it. Therefore, the operating rules for the stove provide strict requirements for the materials used for the construction of the chimney and its installation.
The Buleryan stove can be heated with almost any type of fuel except gaseous and liquid.
- slabs;
- bricks;
- stone;
- other non-combustible material.

Installation of this device involves the manufacture and installation of a 5 m chimney. For powerful models, you will need to make a 7 m chimney. This element is responsible for draft in smoldering mode. If this device smokes a little in gas generation mode, then there is not enough thrust.
The stove is installed at a distance of 60 cm from flammable materials. Before lighting the stove or putting wood in it, you should fully open the smoke damper and regulator. Next, the fuel is placed. After 20 minutes of burning, the stove switches to smoldering mode.
Popular models
Model range by power for the home, garage and bathhouse.
At the moment, there are several popular models of the Breneran brand:
- Breneran AOT-14. This is one of the largest stoves, capable of heating an area of 400 sq.m. Made from steel. Can work for 10 hours. Used for heating cottages and country houses.
- Aqua Breneran. Heating is carried out by circulating the liquid and heating it. Suitable for heating large areas, workshops, workshops. Operating time from one fill of fuel is 6-8 hours. There is a water tank.
- Breneran AOT-08 type 005. Allows you to cook food and heat the house. A gas generator stove is suitable for heating small rooms.
- Aquaten. This is a unique stove with a different design. Its pipes are connected to heating radiators, through which coolant flows. Made of high strength steel. Instead of fuel, a heating element with a power of up to 1 kW can be used to operate the Aqua Breneran boiler.
The choice of a suitable model depends on several criteria: room area, which affects power, type of fuel, dimensions, required functions.
If you have the skills and professional equipment, you can create a stove yourself according to the instructions. Also, a home craftsman can upgrade it with his own hands.
Recommendations for placing heating system elements
Elements of the heating system can hardly be called decoration of a modern interior. Only pipes that look organic in some industrial interiors can fit this definition. In general, building codes and architectural principles recommend placing parts in areas that are hidden but accessible for repair and maintenance. When placing, they are guided by the following rules:
- The heat generator is placed in an isolated room with heating and good ventilation. The circulation pump must operate under the same conditions. Small boilers (with a power of up to 30 kW) can be installed in the kitchen, hallway, basement or warm heated extension. Stoves intended for residential premises are installed taking into account fire safety rules.
- The place for an open-type expansion tank is in the attic; supply and collection pipelines tend to be located along the main wall structures.

- The main riser runs openly in the corners of the living spaces; in the attic it is covered with thermal insulation.
- Radiators are installed openly under window openings. They participate in room circulation, heating the cold air coming from the windows. Attempts to decorate radiators with decorative screens are undesirable, since they reduce the thermal efficiency of the system.
