Bulerian with a water circuit – the principle of operation and features of installation

Efficient home heating is essential for both cost-effectiveness and comfort, particularly in the winter. A technique that is becoming more and more popular is the Bulerian water circuit heating system. However, what is it exactly and how does it function?

The Bulerian heating system works on a straightforward but clever idea. It provides a cost-efficient and sustainable means of staying warm by harnessing the flow of water in the house. Bulerian systems use water circulation to generate heat instead of just using forced air or electric elements, which makes them more energy- and environmentally-efficient.

Bulerian system installation requires a few essential parts. First and foremost, the bulerian serves as the system’s central component and is a specially made apparatus. It is made up of pipes or coils that allow hot water to circulate and release heat into the surrounding air. As the heated air rises, a natural convection current is created, distributing warmth evenly throughout the room.

The Bulerian system’s installation versatility is one of its most notable features. There are options to fit different layouts and tastes, whether you’re designing a new home or retrofitting an existing one. Customization of Bulerian systems to meet specific heating needs is possible thanks to their flexibility, which includes wall-mounted radiators and underfloor heating.

Features and methods of installation Breneran Aquatan

As previously mentioned, you can use any of the available options for connecting water heating because of the stove’s design. The device may be used in systems where the coolant circulates both naturally and through force.

Consider the PPB regulations regarding stove installation, smoke exhaust system connection, and the differences between closed and open systems when performing installation work. The type of boiler piping and coolant used have an impact on the boiler’s performance and heat output.

Requirements for fire safety

For the Akva Breneran water heater, the manufacturer ZAO Laotherm has secured a fire safety certificate. This shows that the boiler is guarded against unintentional ignition and that the likelihood of a fire is reduced when it is operated properly.

The following PPB guidelines for TT boilers are taken into consideration when installing in the living room:

1. The stove must be installed on a solid, non-combustible base. For models AOTV 14, 16 and 19, it is obligatory to make a concrete base.
2. On the furnace side, the floor is covered with a sheet of steel, at least 1.25 m in length.
3. Distance to plastered walls not less than 1 m., with additional insulation 0.8 m.
4. The dimensions of the room for installation of the furnace are not less than 12 m².
5. In the boiler room it is obligatory to have a ventilation duct and good natural air ventilation.
6. Automatic devices for disconnection of the heating element and circulation equipment are installed in adjacent rooms.

For the solid fuel pyrolysis boiler Breneran Aquatan, a safety group comprising a pressure gauge, expansion membrane tank, air valve, and safety is required. Commissioning, in the absence of safety valves, is prohibited.

Installation of smoke exhaust system

A detailed description of the chimney installation regulations can be found in SNiP 41-01-2003 (SP 60).13330). The stove’s capacity determines the height and diameter, as per standard procedures. Pay close attention to the manufacturer’s instructions when installing the chimney:

• The distance to structural units, beams and rafters is calculated depending on the chimney material. For brick and ceramic chimney with insulation, fire clearance of at least 13 cm, without insulation 25 cm.
• The chimney height should be between 5 and 9 m, depending on the model of the stove.
• A deflector is installed on the chimney head to improve the draught characteristics.

Connection to the system with natural circulation

The most common type of heating system is one that allows the coolant to circulate naturally. This type of system is simple to install and requires few additional units. There are various installation-related rules:

• The stove is located at least 0,5 m below the radiators.
• Pipes are placed at an angle – the slope is made in the direction of circulation of the coolant.
• An open expansion tank is installed at the highest point of the heating system. The capacity of the tank is chosen depending on the total volume of the coolant, in the proportion of 10%. Correct installation of an open-type expansion tank is carried out on the return line of the heating system. If the tank is installed in an unheated attic, it is obligatory to insulate the device.
• A safety group is installed on the supply side of the heating medium.

There are stringent guidelines for the piping of the natural circulation heating system with respect to slope angles.

Connection to the system with forced circulation

The closed type heating system differs from the previous variant primarily in that a circulation pump is needed. Among the many benefits of forced coolant circulation are increased heating efficiency, speed, and heat transfer. The reliance on electricity is the only drawback.

The following guidelines are followed during the forced circulation heating system installation process:

• The circulation pump is installed on the return flow of the coolant, between the expansion tank and the boiler. It is recommended to install a temperature sensor, to regulate the boiler, depending on the intensity of heating and pressure created in the closed system.
• The connection is made with a closed-type expansion tank. No air enters the heating system, which has a positive effect on the duration of operation of pipes, radiators and the boiler itself.
• For uninterrupted operation of the pump will need to install a UPS with built-in voltage stabilizer.

The closed heating system’s maximum pressure is limited to 7 atm. The water circuits on the furnace will burst due to large values. A safety group must be installed in order to prevent breakdown.

What pipes are better to do piping

The operation, performance, and other aspects of the heating system are impacted when the boiler is tied with pipes. Selecting the right material requires thoughtful consideration. The top three choices are as follows:

• Tying the heating system with steel pipes – the advantages include resistance to overheating, low linear expansion, durability and high thermal conductivity. The disadvantages include the complexity of installation, the need for welding works.
  Installation is better to do before repairing the premises, so as not to spoil the finish finish finish. Another disadvantage can be considered that the diameter of the pipe water circuit, will be much larger than that of polypropylene or metal plastic, respectively, for heating will require a furnace of greater capacity.
• Heating pipes made of polypropylene – the material has many advantages: light weight, long service life, resistance to heating, attractive appearance, smooth inner surface.
  Laying heating pipes in the house can be done independently. This will require a soldering iron and a few construction tools.
• Metal-plastic pipes – another variant of the material intended for the heating system.
  The advantage of metal plastic is: quick installation, not subject to corrosion, high temperature resistance, plasticity. The disadvantages are the susceptibility of the pipe to "patching".
  Metal-plastic pipes are used for installation of heating systems with forced circulation of the coolant. Permitted for use in industrial conditions.

Pipes made of copper, stainless steel, and other materials can be used for heating. But as reality demonstrates, the most common choices are those listed above.

What coolant is better to pour into the Breneran and the system?

Use regular, distilled water and antifreeze as coolants. Every choice has benefits and drawbacks:

• Water – the main disadvantage is the ability of the liquid to freeze already at a temperature of -1 ° C. Consequently, distilled and ordinary water is used only if it is planned to heat the house throughout the season. It is strictly forbidden to pour water saturated with metals. For long-term operation of the furnace, it is recommended to install water treatment and a filtration system.
• The system can be filled with non-freezing liquid or antifreeze. The heating system will not dimensionalize even if the temperature in the room drops below 15-20 ° C. But the use of antifreeze has its disadvantages. Any leaky connection is sure to leak. The total volume of coolant in the heating system often reaches more than 150 liters. Buying antifreeze requires serious financial investments.

The number and volume of radiators, as well as the furnace’s capacity, are necessary information to compute the coolant volume on your own.

Tips and rules of operation of the Breneran Aquatan boiler

Owners of Breneran Akvaten stoves have left reviews indicating that occasionally, issues arise with device operation and the following:

1. What measures can be taken to prevent the circuit from sizing up?
2. Is it possible to increase the efficiency and heat output of the boiler, if it does not heat well?
3. How to properly sink Akvaten?
4. Is it allowed to install the furnace on the street?

The system’s heat output can be increased by correctly connecting the batteries, following the operating guidelines, and adhering to the terms of service.

How to prevent the circuit from defrosting

There is a 1 kW electric heating element included in the system to keep the coolant from freezing. When the temperature falls to the lowest allowable levels, the installed sensor will alert the heater to turn on after the furnace is powered on. Naturally, emptying the heating system’s coolant completely provides the best defense against sizing. Once the liquid has been removed, the pipes and furnace can tolerate temperature drops above -50 °C. The heating component serves as extra security.

Why does the Breneran Water Breneran heats badly

In general, Breneran provides efficient heating for both homes and businesses. If there are any heating issues, there could be a number of causes:

• Installation errors – if the furnace smokes, does not go into the gas generation mode, the reason lies in the insufficient height of the chimney.
• Installation height of the water heating boiler Bulerian 40-50 cm from the floor level. Failure to comply with this parameter leads to an insufficient volume of oxygen entering the furnace chamber and, consequently, to a decrease in the furnace performance.
• Incorrect calculations – the real power of the Breneran is 10-15% lower than indicated in the technical documentation. This difference should be taken into account during the calculations.
• The number of connected radiators in systems with natural circulation of the coolant, directly affects the intensity of their heat output. The farther away from the stove is the battery, the less it warms up. The last radiators, especially if the gradients are disturbed, will be practically cold.

Prior to use, the Breneran Akvaten must be correctly adjusted, with the parameters and heating medium temperature set. Every setting should be adjusted in accordance with the instructions found in the technical documentation.

How to fire the Akvatan Breneran correctly

Heating the Breneran on your own appears to be pretty challenging at first, but it will get easier with some practice. The following is the stoking principle:

• The power regulator and gasifier are set to the maximum open position.
• Wood chips and paper are used to light the fire.
• After the fire is ignited, the furnace chamber is filled to 80-90%.
• Heating continues until the temperature gauge shows heating up to 180-200°C, approximately 20 minutes.
• Regulator – the gasifier is closed to at least 45°.

Unbroken logs are preferable for stoking. For the door to shut smoothly and securely, the firewood’s length needs to correspond with the firebox’s. While the ash must be removed for the fuel to gasify normally, removal is not required.

The main features of the furnace

In Breneran stoves, pyrolysis extends the operating life of the heat generator’s single fuel charge compared to traditional combustion.

While a regular solid fuel boiler needs to be refueled every four hours, the Breneran-Bulerian can operate for eight hours without the user’s assistance. These devices are referred to as long-burning boilers or stoves.

Keep in mind that 8 hours is by no means a record. Certain heaters can operate for several days on a single charge. However, they cannot be regarded as mobile as Bulerian and are far more massive.

Two flaps or throttles are used to manually control the combustion process in Bulerian heat generators: one flap is mounted on the front door and is used to control power, and the other flap (a slider) is located in the smoke channel and changes the combustion mode from flame to smoldering. The stove can therefore be used in the field, for which it was originally intended (by order of mobile logging crews in Canada), without the need for an electrical supply.

Most models have a temperature scale (outside temperature) and a lock in the form of a movable stopper on the handle of the front flap. A sector-shaped cutout prevents the chimney from completely overlapping, which would have allowed carbon monoxide to enter the room.

In the user’s favor. A horizontal pipe section that connects the heat generator to a vertical chimney and has a length of 0.8 to 1 m is a necessary component for Bulerian. This component, referred to as a "chushka" or "hog," slows down the flue gas combustion process. It has a gate valve installed behind it.

The term "economizer" refers to the 1.5–3 m long vertical chimney section after the damper that has strong thermal insulation. This is a crucial component. This is the last stage of flue gas afterburning. The "flame jump" effect occurs when flue gases are affected by the infrared radiation reflected by the walls and flare up in the center of the gas jet.

Following installation, Aqua Breneran

The ignited gas rapidly expands and becomes almost like a plug, which slows down the furnace’s combustion. After it cools down and exits the chimney, combustion can once again begin. The only reason the developers were able to stabilize the burning mode at relatively low temperatures—which was on the verge of smoldering—was because of this cunning trick. An additional benefit is that the furnace automatically adjusts to the fuel quality because it is operating in the auto oscillation mode.

The Bulerian loses 65% of its efficiency when an economizer is not used.

A temperature of between 550 and 650 degrees Celsius is needed for the wood fuel and smoldering mode of a Bulerian-Breneran stove with a water circuit. If you use coal to fire it (coal has a burning temperature of 800–900 degrees Celsius), the furnace will burn out in one to two seasons.

Bouleryan’s dismissal goes like this:

1. Having moved both dampers to the fully open position, the furnace firebox is filled with some flammable fuel (even paper or cardboard will do), which is then set on fire. For some time the furnace works in flame mode, which allows you to quickly warm up the room. It is desirable to lay such a portion of fuel that it completely turns into coals for 3 – 4 minutes before the room is fully heated up. The best way to keep an eye on the combustion process is through the transparent door made of heat-resistant glass, but if your model does not have this option, you can look through the under-blower.
2. Large logs are placed on top of the fuel that has burned down to coals. Pellet pellets or peat briquettes can also be used. The chamber should be filled "to the brim" – then the furnace will be able to work on one charge for a maximum period of time.

In this instance, the front choke is closed to the value that corresponds to the necessary power output, and the damper is fully closed (keep in mind that it has a cutout). With pyrolysis, the bulbarian will transition to a smoldering state.

A stove that has a long burn time between wood deliveries is far more convenient and efficient to operate. The type of long-burning wood-fired boilers for the home, their proper maintenance, and things to look for when purchasing them will all be covered in the upcoming article.

This is a classification of cast iron wood stoves for residential use.

Installation of a water jacketed furnace

The Bulerian stove is placed on a non-combustible stand at least one meter away from the wall (this distance can be lowered to 0.8 meters if fire-resistant plaster is present, which must be at least 25 mm thick).

The stand’s dimensions ought to be 600 mm greater than the stove’s (300 mm on each side).

Within a 1.2-meter radius surrounding the door, there should be steel planking on an asbestos cushion with a thickness of 1.5 mm on the floor.

Solid fuel equipment is connected to the heating system using a unique scheme since it offers significantly fewer options for power regulation than gas equipment. Preventing the coolant from boiling, which has the potential to burst pipes, or allowing it to enter the heat exchanger below 50 degrees is essential to avoid the formation of chemically aggressive condensate on the circuit walls.

This plan includes a safety group and a bypass linking the "supply" and "return" lines:

• safety valve;
• The bypass is equipped with a 3-way valve with servo drive, which is controlled by the temperature sensor of the automatic air vent;
• pressure gauge.

Should the heating medium boil, an overpressure release valve will release the excess pressure.

On the bypass, there is a 3-way valve with servo drive that is managed by a temperature sensor. The temperature sensor opens the 3-way valve and dilutes the cold coolant with hot water via the bypass if the temperature in the "return" drops too low.

An overview of how to operate the Bulerian stove

Similar to a gas heat generator, starting up a heating system with a solid fuel boiler involves some additional steps. The small circuit’s coolant must first be heated before small amounts of cold water from the main system are added.

Knowing how to install and operate a Bulerian with a water circuit is crucial when it comes to home insulation and heating. This heating system uses water circulation to disperse heat throughout a home, which is a straightforward but efficient principle. To ensure even heating, pipes and radiators must be installed strategically. A few benefits of the Bulerian system are its effective heat distribution and its ability to be integrated with renewable energy sources, such as solar panels. Understanding its fundamentals and the nuances of installation will enable homeowners to make well-informed decisions regarding their heating requirements, guaranteeing year-round comfort and energy efficiency.

Efficiency compared to gas heating

In terms of operating costs and convenience of use, gas heating is by far the best option available today. However, it still trails Bulerian in a few areas:

1. A gas boiler cannot be connected without the authorization of the gas utility.
2. The operation of the gas boiler depends on the operation of the gas supply system, while the Bulerian is completely autonomous.

Gas fuel is explosive and poisonous. Its volatility also makes it easy for it to spread throughout the space. But in this regard, boulerian presents no threat.

Types of stoves Aqua Breneran

CJSC "Laotherm," the maker of Akvaten Breneran boilers, has created and manufactured a number of fundamental adjustments for gas generator stoves with a water circuit. High efficiency and the inclusion of an electric TEN, which lets you keep heating the space even after the solid fuel runs out, are two advantages of the models.

If needed, an indirect heating boiler is added to the stove to provide the necessary quantity of hot water.

The following modifications represent the model range of Russian Breneran Akvaten solid fuel gas generator stoves:

• AOTV 19 – one of the most productive models of the lineup. Suitable for heating industrial and domestic premises. The design provides anti-freezing system. Breneran Akvaten AOTV 19 has a powerful ability to heat buildings with a total volume of up to 1000 m³. Efficiency is 70%, and one load of wood is enough for autonomous operation for 6-10 hours. The weight of the structure, with an empty furnace chamber is 350 kg, which requires the preliminary manufacture of the foundation for the installation of the furnace.
• AOTV 16 is a model, which is considerably inferior to the previous series in terms of performance. Wood boiler Bulerian with a water circuit AOTV 16 is able to heat a room with a total volume of 600 m³. Weight of the construction with an empty furnace chamber is no more than 320 kg. The model is optimally suited for industrial or warehouse premises, exhibition halls, cottage and country houses.

• AOTV 06 – model, in the series of Breneran heat generators with the lowest capacity. Performance is enough for only 100 m³, practically for one room with 30-40 sq. m. The weight of the equipment is only 86 kg, which greatly facilitates the installation and installation of the furnace Aqua Breneran AOTV 06.

Consider the wood heating stove’s performance when selecting a long-burning model with a Breneran Aquatan water circuit. The coolant volume and the actual heated area are indicated in the technical documentation.

How much does the Breneran Aquatan cost

Depending on the model and capacity, the price of the Breneran Aquatan stove is marginally more than that of models without a water "jacket."

• AOTV 06 – will cost 16,200 rubles.
• AOTV 11 – for this model you will have to pay 23 800 rubles.
• AOTV 14 – the cost will be 27 400 rubles.
• AOTV 16 and 19 – for semi-industrial models will have to lay out 45 and 55 thousand. rub. accordingly.

The total cost of pyrolysis boilers for long-burning solid fuel Breneran Aquatan is determined based on the additional equipment that may be required. The cost of the installation, the connection to the heating system, and other expenses are also considered. д.

Advantages of water heating from Breneran

Compared to analogs that operate on the principle of air heating, Breneran gas generator stoves offer a number of noteworthy advantages.

• Heating of rooms is carried out with the help of standard heating radiators, and not through air circulation. Therefore, the models are suitable for heating one- and two-story individual houses, and there is no need for additional equipment in the form of air ducts.
• Can be installed in a house without a basement. With proper installation and regular maintenance of the furnace, there is no chance of smoke entering the room.
• The Breneran Akvatan stove is welded from steel, 2-3 mm thick for the outer casing and 5 mm thick for the furnace chamber. In manufacturing, heat-resistant alloys are used, which significantly increases the service life of the device.
• Ability to connect to a heating system of almost any type. The main thing is to correctly select and calculate the capacity of the stove. Breneran feels equally well when connected to a heating system with natural and forced circulation.
• Simple installation. It makes sense to put a modification of the furnace Breneran with the connection of water heating system, if there is no desire and possibility to connect gas heating. Akvaten model provides maximum convenience of operation. If necessary, can operate in the anti-freeze mode. Electric heating element heats the coolant to the required temperature.

Disadvantages of water boilers Breneran

Of course, there are drawbacks to boilers Breneran Aquatan, but they are so negligible and secondary to the benefits that there is hardly any information about them on building forums or other websites. However, based on a few remarks we were able to locate, the stove’s issues are as follows:

• It will not be possible to use the Breneran Aquatan without water. The design is provided exclusively for liquid cooling.
• Akvaten has inherent disadvantages of all gas-generator models. The characteristics and performance is affected by the quality of fuel, errors in the installation of the chimney pipe.

The stove should operate almost trouble-free if the installation is completed in compliance with all of the manufacturer’s instructions.

All things considered, adding a Bulerian with a water circuit can greatly enhance your home’s insulation and heating. This creative system uses the water’s natural circulation to disperse heat evenly throughout your home. It works on a straightforward but efficient principle.
