The operation of the circuit with connecting a boiler, without a backup boiler and underfloor heating
The circulation pump (P) supplies the heating medium from the heating system, passing it through the boiler.
The heated coolant from the Stropuva S 40 boiler (1k) is fed through an indirect heating boiler (B). With a sufficient diameter of the boiler inlet pipes, the valve (3) closes and the entire flow of the coolant goes through the boiler, which is connected in series, so the water in it heats up faster.
After heating the domestic water (DHW), the coolant enters the radiator system.
(bk3 - 17) - balancing valve designed to regulate the flow. With its help, the flow from the circulation pump is distributed so that it is enough to heat the radiators, and at the same time, so that it is sufficient for the boiler itself. The total flow volume depends on the power of the circulation pump and can be changed by switching the pump speed positions. A 50-100 W circulating pump is enough.
(bk1 - 3) - balance valve of the protective gravity radiator, with the help of which the flow is adjusted so that the return pipe of the radiator is about 40 ° C colder than the supply pipe.

Operation of the circuit with connecting a boiler and a warm floor, without a backup boiler
The heating medium heated in the Stropuva S40 / S40U boiler passes through steel pipes ø 25. The air is removed from the device through an automatic air vent (0). A safety valve (9) is installed on the external circuit.
The heat carrier is directed along the external circuit to the three-way mixing unit (12). A mixing unit (12) in the lower part of the circuit is required for mixing the return heat carrier after the circulation pump.
The temperature difference between the supply and return coolant must be within 15-20 ° C. Accordingly, at a flow temperature of 75 ° C, the return temperature should be 55-60 ° C.
The boiler (4) is connected in a small circuit through the valve (8a, 8b). After heating the boiler, water enters the nearest radiator (2) through the balance valve (8c).
An additional radiator (2) must be connected autonomously. The radiator is necessary to prevent the boiler from overheating when the circulation pump (7a) is turned off.
The radiator system is connected at the top of the small circuit through a valve (8d). The return line from the radiators is fed to the circulation pump (7a) through a valve (8f). On a small circuit, after taking the coolant to the radiators, the underfloor heating is connected through the circulation pump (7b).
The heating medium from the underfloor heating return line is supplied to the three-way distribution valve (6) through the valve (8e).
A three-way mixing valve (6) is required for mixing the supply and return lines and bringing the temperature of the underfloor heating supply line to a temperature of 25-35 ° C.
The three-way diverting valve (12) is connected to the circulation pump (7a) to a common return line. In the lower part of the circuit, after the mixing unit (12), a balancing valve (13) with a flow meter is installed to regulate the flow of water into the boiler.
In the return line, after the balancing valve (13), drain valves (14a, 14b) are installed to make up and drain the coolant from the system, as well as an expansion tank (10). The pressure in the expansion tank should be 0.5-0.8 atmospheres.
Nuances when performing strapping
The piping of solid fuel boilers should be carried out taking into account the following recommendations:
- All connections must be made properly.
- The most popular schemes are with two circuits.
- The use of pipes made of hot materials is prohibited. Polypropylene strapping is possible only if certified goods are used.
- Regular maintenance will keep the system in good working order.
- The coolant must be clean to avoid premature pipe damage.
- Correctly and correctly executed piping will only be considered effective when the power of the solid fuel boiler is correctly calculated.
- An air vent will avoid airing the system.
- To prevent leaks at the joints, it is better to use paronite.
- The natural course of the coolant is best used for small rooms.
- The dimensions of the expansion tanks have always mattered - the larger the piping, the larger the tank dimensions.
- The quality of all units, parts and elements used determines the overall quality of the strapping. Low-quality parts are a sensible step towards future waste.
- The piping of solid fuel boilers must take into account the off-season period in order to avoid overheating of the premises.
Advantages and disadvantages
Sectional diagram of the Stropuva boiler
It is worth briefly listing the main advantages of the Stropuva boilers:
- Efficiency and convenience - they do not require expensive gas supply for their installation, and a long operating time on a one-time fuel filling saves money and time.
- Energy independence - there is no electronics in the design, therefore wood-burning boilers, when used in a gravitational heating system, do not need electricity.
- Safety and reliability - one of the advantages is control with a bimetallic valve - a simple and trouble-free draft regulator.
- Aesthetics along with simplicity - STROPUVA boilers differ from a similar type of devices in their elegant appearance and compact placement. The clear design of the unit eliminates any difficulties in operation.
Among the disadvantages, the following can be noted: their performance is strongly influenced by the moisture content of the loaded fuel. But this is rather a minus of all solid fuel boilers, and not of a specific brand in particular. The solution here is simple - keep wood or coal in a dry place.
Checking the boiler sling
Before permanent use of the boiler, it is imperative to carry out tests of its functionality. This is necessary in order to further operate the boiler in a safe mode.
So, you will need to fill the barrel of the apparatus with firewood up to a third. From above, it is covered with a lid, and before that you need to throw a match into the barrel so that the fire begins to flare up. For better ignition, it is imperative to add kerosene there.
Ideally, the firewood should immediately burn up. At the same time, there should be no draft, no smoke, no smell. If any of the above is observed, then you should not use such a boiler. With a high probability, he will harm the owners of the house. However, if everything was done correctly, then there shouldn't be such problems.
The specified amount of firewood is enough to heat a small room for a day.
Boiler device Stropuva
To answer the question of whether it is possible to make Stropuv's boiler with your own hands, you first need to honestly determine the degree of your skill. If you are a jack of all trades with a developed savvy, then the process may be within your power. If you are a homemade "DIY", then, most likely, there will be no sense, because the task is really difficult. To verify this, consider the design of the Stropuva boiler. It consists of the following main structural elements:
- double body;
- telescopic air duct;
- air distributor;
- automatic air supply control system.
Of course, Stropuva's long-burning boilers are equipped with doors, nozzles for supplying and returning the coolant. There will be no difficulties with simple elements, it is simply impossible to make the basic ones at home. Let's start with a telescopic tube, how do you make it yourself? It's impossible without factory equipment. On this, in principle, it is possible to end, the attempt failed. Hypothetically, let's say that you managed to make a telescopic duct that can be folded by pulling on the cord.
Surely you have identified a ring on a string in Stropuv's long-burning boilers. It is designed to lift the air supply pipe.
The unit diagram is really complex. You need to do the following:
- connect two pipes of different diameters;
- in the outer pipe, cut in the pipes for the supply and return of the coolant;
- in the inner pipe from above (exactly in the middle), fix the chamber for heating the air;
- fix the already made telescopic air duct with an air distributor at the end in the chamber from below;
- you should also make a branch pipe for removing smoke from the inner pipe;
- install doors;
- put an air supply control system.
In this case, everything should be as tight as possible. Can you cope with such a difficult task? Most likely not.So Mr. Afanasy Budyakin from Kolyma thought that this was an impossible task, so he came up with an analogue of Stropuv's boiler. I didn't name him in any way, but just posted it on the network under the nickname "bybafonja". And so the name "Bubafonya" stuck to the domestic long-burning stove. We will talk about it a little later.
Before choosing a convector heater for your home, calculate the required power.
What is the best quality home heater? The answer is here.
Basic models
You can buy a Stropuva boiler in specialized stores that are dealers of the manufacturer, as well as in online stores. The minimum price is 60 thousand rubles for the minimum power model. Let's continue the review with a description of the manufactured models.
Lanyard Mini S8
Before us is the smallest wood-burning boiler with a capacity of 8 kW, designed to heat rooms up to 80 square meters. m. It works on wood briquettes and wood, equipped with a safety valve and a thermometer. The heating temperature of the coolant is from +60 to +95 degrees. The maximum pressure in the circuit is up to 1.5 bar. The efficiency of the model is 85% - a pretty good result for solid fuel equipment. The estimated cost of this boiler is 61 thousand rubles.
Lanyard Mini SP8
This boiler differs from the previous model in its support for working on pellets. In this mode, it needs to be connected to a 220 Volt power grid - electricity is used to operate the fan used in the fuel ignition system. When working on wood and briquettes, the boiler works in an autonomous mode. The rest of the parameters are almost 100% similar.
Slings S20
One of the most popular models. It allows you to heat residential buildings with an area of up to 200 sq. m. The boiler is built according to a non-volatile scheme, briquettes and ordinary firewood are used as fuel. Burning time is up to 31 hours. If you want to forget about laying fuel for a few days, we recommend purchasing the Stropuva S20U modification - it can work on coal, providing up to 120 hours of continuous combustion. The Stropuva S20P model can work on pellets for up to three hours.
Slings S40
Before us is the most powerful boiler in the entire line. Its thermal power is 40 kW, burning time - up to 31 hours, heated area - up to 400 sq. m. The device is equipped with a rather impressive jacket-heat exchanger, containing 58 liters of water. The maximum pressure in the system is up to 2 atmospheres at an average temperature of up to +75 degrees. More than 90 kg of firewood is placed in the combustion chamber of the device. Modifications are also available for operation on pellets and coal.
Other models and manufactured modifications
Also on sale are solid fuel boilers from the Stropuva company with a capacity of 15 and 30 kW. They are designed for areas up to 150 and 300 sq. m.All models considered in the review are available in three modifications:
- The main one is that the equipment operates only on wood and fuel briquettes (euro wood).
- With index P - it is possible to work on pellets, burning up to 72 hours.
- With the U index - units with the ability to work on coal, burning time up to 120 hours.
Naturally, the actual burning time can be shorter - it depends on the characteristics of the fuel (type of wood, degree of dryness).
Some people have design requirements for heating equipment.
If it is really so important to you how the boiler looks, then we have good news - Stropuva produces his equipment in several colors. The main color (and most common) is yellow
It is possible to purchase boilers in brown, blue, red, green and black colors. Spotted color is also provided (yellow and dirty green).
Solid fuel boiler piping.
One of the most popular heating systems of a private house, summer house, cottages is a system built using solid fuel boilers.A home mini boiler room based on Mechanicenne equipment guarantees constant warmth in the house, the availability of hot water and comfort.
Solid fuel boilers Mechaniken are long-burning heating equipment with high efficiency. The combustion process in the boiler takes place according to the principle of a candle - solid fuel gradually burns from above, ensuring the most efficient use of the released thermal energy. The burning time of one bookmark is from 1 to 5 days. The following can be used as fuel:
- firewood;
- briquettes;
- pellets;
- coal.
Boilers are produced 10,20,40 and 50 kW. Depending on the capacity of the floor-standing solid fuel boiler, they can support heating of premises with a total area of 50 to 500 m2.
Installation and assembly of the Stropuva S20 boiler
The Stropuva S20 / S20U / S10 boiler is installed in rooms that meet the national requirements for boiler rooms. The height of the room in which the device will be installed must be at least 215cm.
The floor must be concrete (at least in the place where the boiler will stand). The room must be insulated from the heated living quarters and must have a vertical ventilation duct and a window or hole in the outer wall so that air from outside can easily penetrate into the boiler and the ventilation duct.
Using a mirror, the inside of the chimney is inspected through the chimney cleaning hole.
The chimney must be clean. It should be free of fittings or bird nests and openings in hollow ceilings and adjacent shafts.
It is checked whether there are openings in the chimney from the outside, through which parasitic air can enter, cooling the chimney and reducing draft in it. All openings and joints in the chimney must be sealed.
If there are internal holes in the chimney in ceilings or adjacent shafts and it is impossible to seal them, an oval or cylindrical stainless steel liner must be inserted (rectangular liners are unreliable due to holes formed at the joints due to temperature changes).
The installation of the Stropuva S 20 boiler is carried out directly on the concrete floor, and the gaps between the floor and the boiler are closed with a heat-resistant material (silicone (180˚C) or a solution of lime and cement with sand or other materials).
The boiler can be placed on a concrete bottom for installation with a sealing rope.
When carrying the unit, sometimes its parts are deformed, therefore, after installing it in the chimney and closing all the doors, as well as the holes for cleaning the chimney, check the operation of the upper damper, whether it adjoins the surface of the air supply hole, and the tightness of the doors using a candle flame or matches.

The diagonal of the chimney opening can be 10% less than indicated in the basic technical data, but not more than twice.
Stropuva boiler or Bubafonya stove
List of structural elements of the Stropuva boiler.
In the previous article, we talked about long-burning stoves for a house, a summer residence, a bath, how to heat them. Today we will talk about two similar units in their principle of operation - the Lithuanian boiler Stropuva and Bubafonya from Kolyma, and even try to compare them. Those who think whether it is possible to make Stropuv's boiler with their own hands will have to be upset, most likely, this will not work.
Some structural elements are very complex and can only be produced in a production environment using machine tools. But the domestic, simplified analogue can be assembled in a day. Of course, it does not have such high characteristics as factory units, nevertheless, it will heat a summer cottage or garage in no time. The variant is super economical and practical, like the AK-47.

We will talk about it a little later.
Before choosing a convector heater for your home, calculate the required power.
What is the best quality home heater? The answer is here.
The principle of operation of the boiler Stropuva
After the flame has sufficiently flared up, it will begin to burn from top to bottom.
Both the original and the analogue of the Stropuva boiler work on the same principle. First you need to load the firebox with bitter. Let's make a reservation right away that this can be done only after the boiler has completely burned out the previous supply of fuel, since the source of smoldering should be at the top. To start up the boiler you need:
- pull the ring and lift the telescopic air duct;
- remove ash through the lower door (1-2 times a week);
- fill the firebox with wood or coal, depending on the model of the unit (there are wood and universal ones);
- set fire to paper or cloth soaked in gasoline from above;
- lower the air duct and close the doors.
From one load of firewood, the boiler works a little more than a day, from a briquette - up to two days, and on coal - as much as five days.
As the fuel burns out, the air distributor moves down until it reaches the bottom. The air supply is controlled by a bimetallic plate. The developers have increased the efficiency due to the fact that an air heating chamber is built into the Stropuv boiler device. The latter enters the furnace at a temperature of about 400 degrees. At this temperature, pyrolysis gases ignite. But, unfortunately, the plate loses its properties and every month you need to make adjustments in the settings, and after a year, replace it with a new one.
Due to the fact that the air is supplied in a metered manner, it is possible to avoid temperature surges that occur during the operation of ordinary solid fuel boilers.Therefore, the piping scheme of the Stropuva boiler does without an accumulation tank, the so-called heat accumulator for the heating system.
Modern autonomous home heaters are energy-saving units with high efficiency.
Infrared lamp heaters for the home, unlike lamp TVs, are the latest heating equipment. Here you will find both types and characteristics.
Boiler connection diagram Stropuva
Piping scheme with a backup heater, hot water boiler and underfloor heating.
After the purchase, filling out the documents, the seller will ask you: "Do you need the help of a master in installing the heater?" Take your time to answer "No." The connection diagram of the Stropuva boiler is somewhat different from other types of solid fuel boilers. On the official website, you can find three strapping options:
- with backup heater, hot water boiler and underfloor heating system;
- only with a boiler;
- with a boiler and a low-temperature underfloor heating system.
Maybe for someone it is, as they say, "one spit", but for a person without specialized knowledge, these schemes cause a stupor. This is not to mention the fact that you independently connect the Stropuva heating boiler. In general, it is still better to use the services of experts in this matter. By the way, opinions have been heard more than once on the forums about the complexity of strapping this equipment.
Bubafonya stove with a water jacket
Bubafonya pyrolysis oven from a gas cylinder with a water jacket.
Finally, we got to the domestic analogue of the Stropuva boiler, which is much easier to design, since it has a non-folding pipe for supplying air to the furnace. There are already so many instructions on how to make a Bubafon stove with your own hands that only a blind person did not see them, if, of course, he was interested in this topic. And all why? Because the process is so simple and if you get down to business seriously, you can get a finished product from scratch in a day. What the Bubafonya stove is not made of with your own hands:
- from a gas cylinder;
- from a barrel;
- from pipes.
It can be either round or square. We will not repeat the same thing, just read the article: "Bubafonya stove from a gas cylinder" - and everything will become clear to you. Today we will consider a version of a product with a water circuit, as if we will try to repeat the principle of operation of the Stropuva boiler. All that is required is to make a simple Bubafon and insert it into a larger pipe. Thus, we get a gap in which the coolant will be heated.
Naturally, this space above and below is welded so that various debris does not get there. What is important when making a do-it-yourself Bubafonya oven with a water jacket:
- use of heat-resistant steel;
- wall thickness not less than 4 mm;
- availability of a tap for draining and replenishing water.
Immediately provide a hole in the upper part through the outer and inner walls for installing a chimney into it. There should also be enough space for water. The distance from the outer to the inner wall is about 10 cm. When connecting, do not confuse the supply and return pipes (supply from above).
Comparison of the Stropuva boiler and the Bubafonya furnace
We will start our analysis with the scope. If we are talking about a residential building, clearly, the advantage belongs to the Stropuva boiler. The characteristics of this unit allow it to work for a long time on one load, it is stable and reliable. At least there have not been any cases of complete refusal yet. The principle of operation of the Stropuva boiler allows you to connect to it both high-temperature heating and a hot water supply system with underfloor heating. Bubafonya cannot boast of this.
Rather, it is suitable for heating greenhouses, garages, maximum summer cottages. For more serious projects, it is simply not applicable. The advantages of the Stropuva boiler design:
- continuous work on coal for 5 days;
- temperature stability;
- convenience of loading fuel, compared to Bubafony.
There are also disadvantages, such as the complexity of the piping, the need for a separate room and the impossibility of repairing to a complete stop.It is also impossible to add fuel while the furnace is in operation, and therefore it is necessary to re-fire it every time after a new load of the furnace. But at the same time, for serious projects, of the two compared units, only the factory Stropuva furnace is suitable. But the invention of Afanasy Budyakin is great for utility rooms, since the Bubafonya stove can be made quickly and inexpensively, which in this case is of decisive importance.

How to start the boiler Stropuva
First you need to purchase a piping kit for connecting the equipment with the heating system. We recommend buying a kit with the ability to connect an indirect heating boiler. It includes a set of pipes, a safety group, an expansion tank and a circulation pump. Also on sale are kits for connecting warm floors.
It is not recommended to use raw firewood - this will become an obstacle to the normal operation of the boiler.
Ignition is carried out in the following way - here's a short instruction for use:
- We load a full firewood combustion chamber with the air distributor raised.
- We fill up the finished masonry with sawdust.
- We open the flap for switching to firewood.
- Open the air damper 3-5 cm.
- We kindle the top layer, cover the loading door, leaving a gap 3-5 cm wide.
- We wait for a steady combustion, close the loading door and immediately lower the air distributor.
Please note that the cleaning door must be closed. A new portion of firewood can be thrown into Stropuv's boiler at any time, but it is dangerous to do this with coal
In any case, the manufacturer recommends to always wait for the final burnout of the fuel before adding a new portion.
A new portion of firewood can be thrown into Stropuv's boiler at any time, but it is dangerous to do this with coal. In any case, the manufacturer recommends to always wait for the final burnout of the fuel before adding a new portion.
The importance of piping during the installation of the boiler
A home mini boiler room will work correctly, uninterruptedly and safely only if the installation and piping of the solid fuel boiler are correctly completed. A normally functioning heating system must ensure an even distribution of heat energy to all radiators, underfloor heating and a boiler, prevent the coolant from overheating, and ensure a continuous supply of warm water. The above will be possible only if the piping is correctly performed.
Installation of a boiler with piping is the creation of an engineering system of a house that provides heat and warm water to residents. The system includes a boiler, a wall-mounted or floor-mounted indirect heating boiler, heating radiators, coolant supply lines or other water-heating equipment, ventilation and smoke removal system elements.
Incorrectly executed piping can lead to high fuel consumption and a decrease in boiler efficiency, uneven and insufficient heating of the premises (pressure drop in the system and its airing), as well as failure of the boiler and other heating equipment. As a result, costly repairs and reassembly will be required. During installation, special attention must be paid to the correct installation of the security system, which includes a pressure valve (1.5 bar), an air vent, emergency and temperature sensors of the automation. Boilers "Mechanicenn" are manufactured according to TU and, if used correctly, are safe to use.
What does the boiler piping include?
The universal and simplest piping scheme for a solid fuel boiler provides for the use of the following equipment:
- circulation pump - contributes to the forced movement of the liquid (heat carrier) through the pipes of the heating system;
- expansion tank of a certain volume - a membrane tank is installed, which acts as a buffer that excludes water hammer;
- heating radiators and underfloor heating - devices through which heat energy is transferred from the coolant into the air to heat the premises;
- water heating devices - an additional unit (boiler) used for parallel heating of water used for personal hygiene of residents;
- pipelines - polypropylene or metal pipes, through which the coolant is supplied, return flow is provided;
- a group of safety elements and shut-off valves are needed in order to control and adjust the operation of the heating system, excluding any emergencies.
Polypropylene strapping
Installation of solid fuel boilers using polypropylene pipes of the appropriate diameter provides quick piping of the boiler and the creation of a heating system of any configuration complexity. Pipes made of this material are highly reliable and efficient during operation. They can easily withstand water pressure up to 25 bar, which can have temperatures up to + 95 ° C.

As mentioned above, the quality of the fuel is of great importance. And for the efficiency of heating equipment, and to increase its service life. This is especially true for firewood - a very unstable type of fuel. The efficiency of the boiler depends on a uniform supply of fuel, moreover, equalized in terms of its calorific value.
This is most important for modern high-tech heating devices, burdened with automation.
Firewood, however, differ in their technical qualities - humidity, specific heat of combustion. That is why manufacturers of boiler equipment insist on choosing high-quality fuel.
Pellets and fuel briquettes - more efficient fuel for a wood-fired boiler
The simplest way to achieve this requirement is to choose artificial "logs" - pellets, fuel briquettes.
You can read in more detail about the differences between firewood and their types in the article Pros and cons of various types of solid fuel for boilers: wood and its derivatives.
In the manufacturer's recommendations, as a rule, there is an indication of how long the logs are suitable for a particular model of the firebox. There are variants of boilers that fit meter-long logs into the combustion chamber.
A log of a log of strife
Wood of different tree species has a different density, which means - the ability to produce heat. But, in addition to it, other features of firewood are important that affect the operation of the boiler: the amount of non-combustible (ballast) substances and the presence of resins that contaminate the chimney and the internal structure of the device during combustion.
Birch firewood
Birch has dense wood, so it burns hot and emits a lot of heat - 3750 kcal, even if the wood is damp. It is highly flammable. But when burning such firewood, especially damp, tar is released - a substance useful in medicine, cosmetology or for protecting surfaces from decay, but extremely harmful to the insides of the boiler.
Soot on the boiler heat exchanger
Alder firewood
Burning alder wood practically does not emit soot. Moreover, burning alder wood helps to clean the chimney. Alder is highly flammable, burns well and emits a sufficient amount of heat - 2100 kcal.
Aspen firewood
Burning aspen, like alder, cleans the chimney. But by themselves, such firewood, when burning, emit a little heat - up to 1650 kcal.
Pine firewood
They burn well and quite hot (3800 kcal), but pine wood is resinous, and a lot of soot is formed during combustion.
Firewood in the warehouse meter
Spruce firewood
Spruce firewood is comparable in quality to pine firewood, but it has a slightly higher specific heat of combustion - 3900 kcal, moreover, it is less resinous.
Poplar firewood
Poplar burns hot, but burns out quickly.
Apple and pear firewood
Firewood from fruit trees - apple or pear - has dense wood, which means it emits a lot of heat, burns and smolders for a long time. But these breeds are usually grown for the sake of fruit, so such firewood is not common. Another feature: the trunks of pears and apple trees are gnarled, the chocks do not prick well, and the logs turn out to be knotty, it is difficult to stack them tightly in the firebox.
Oak, beech, ash firewood
Oak, beech, ash have dense wood; when these species burn, a lot of heat is released - up to 3600 kcal. Of the minuses of oak or beech firewood, one can name their rarity on sale and the difficulty in splitting and melting the boiler with them.
Taking into account the described qualities of wood as fuel, a good owner stores different types of firewood: some - so that they easily flare up, the second - so that they burn for a long time and hot, and still others - to periodically clean the chimney from soot.
Work reservation
The Stropuva boiler will delight you with a long burning fuel. But even in this case, you can miss the moment of the next bookmark. As a result, the temperature of the coolant in the heating circuit will begin to drop. To prevent this from happening, we recommend installing a backup electric boiler in the circuit. Upon detecting a drop in temperature below the set limit, it will turn on and maintain the set temperature.
Electricity consumption will be small, if you do not forget about laying firewood for 2-3 days. Most of the time, the boiler will burn, providing consumers with heat. Therefore, one should not expect huge expenses. In addition, the auxiliary boiler does not have to be as powerful as the main one - a model with a capacity 2-3 times lower is quite enough, so as not to rattle teeth by the morning. We also recommend that you work on insulating your home so that it retains the accumulated heat for a longer time.
Features of boilers Stropuva
Sling boiler device
- Stropuva boilers, the piping scheme of which is quite simple and reliable, have the main distinguishing feature - they are long-burning units. This principle of operation provides fuel and time savings, which is very important for the modern consumer;
- Some models of Stropuva should be filled with solid fuel once every 12 days, and there are those that are capable of operating without user intervention for 3-7 days after loading;
- The design features allow you to install a solid fuel slingshot boiler with your own hands, if you act according to the manufacturer's instructions. The piping scheme should not cause problems;
- These boilers from Stropuv are top-fired boilers, which opens up many advantages of the equipment;
- Fuel is ignited from above, burning out occurs in thin layers. Gradually, the solid fuel drops, which increases the duration of combustion. A feature of Stropuv's work technology is that more heat is emitted;
- At an insignificant level of load (about 15 percent of the maximum power), the boiler demonstrates a high efficiency;
- The combustion center is constantly moving inside the Stropuva boiler, which ensures a decrease in thermal constant loads on individual sections of the equipment. This significantly increases the service life;
- Wood-fired models must be filled with wood approximately every 30 hours;
- Boilers from Stropuv, which use briquettes, can be loaded with fuel every 2-3 days;
- Coal in Stropuva's boilers makes it possible to forget about the need to lay a new portion of coal for 3-5 days. At the same time, the house will be constantly warm.
How to light a boiler
In cycling, the most difficult thing is not to ride, but to start and finish the movement. So it is in the operation of the boiler - the most difficult thing is to melt it. Do not expect that lighting the boiler will take you little time: you will have to allocate about an hour for this procedure.
Heating a wood boiler is a responsible occupation
Commencement of the furnace - ash removal and preparation of the boiler for operation. After the ash pan and combustion chamber are cleaned, you can proceed to kindling.
Heating up the boiler furnace and chimney
For your own comfort and proper start-up of the boiler, you need to warm up its firebox and chimney. If the heater is not equipped with a forced smoke exhaust system, in order for the fuel to start burning, it is necessary to create a draft. The formation of thrust is based on Archimedes' law: heated gases become lighter and tend to "float". For their movement and removal, heating devices operating on fuel combustion are equipped with a chimney.

The design of the boiler is such that the path for smoke is difficult: on its way there is a heat exchanger and a convective surface of a complex shape, which reduces the speed of movement of combustion products. And the chimney pipe is usually located horizontally, which also makes it difficult for the smoke to move. Therefore, if the boiler is not warmed up, the combustion products are looking for the easiest way. And more often than not, smoke begins to seep into the room.
In some cases, the vertical part of the chimney is equipped with a flood (a small furnace that serves to warm up the chimney) with a door, opening which you can burn a small amount of flammable fuel (for example, paper) directly in the chimney itself. When using flooding, the inside of the chimney is warmed up.
If such a possibility is not provided, then a kindling is laid in the firebox - crumpled paper, birch bark - something highly flammable. On top of the kindling - chips and splinters, then logs of small thickness. The combustion chamber must be filled with firewood to no more than half of the estimated volume.
At the moment of kindling, you need to open the chimney damper and the blower valve, ensuring the flow of combustion air.
There are tips to open the window in the boiler room before starting the furnace, if there is one: do not forget that oxygen is needed for the physicochemical combustion process.
How to properly heat the boiler with wood
It takes about 5 cubic meters of air to burn a kilogram of firewood. If the air flow into the boiler furnace is from the boiler room, then it is imperative to arrange supply ventilation - especially if there are no windows in the boiler room or they are sealed (with double-glazed windows).
After placing the logs, the kindling is ignited. When a steady combustion appears, the door of the firebox must be closed and the bookmark must be allowed to burn out.
Achievement of design power
As soon as the combustion chamber and chimney have warmed up sufficiently, you can proceed to the main stage of the boiler operation. To do this, repeat the kindling process using well-burning materials. Now the main laying of firewood is already complete, in order, according to the instructions for the device, to fill the combustion chamber.
After the fuel has ignited, the boiler will reach its design power after a while. Now the combustion process will take place on its own for some time. How long depends on the volume of the combustion chamber and the principle of operation of the boiler. After the firewood bookmark burns out, you need to make a new one.

Important! When lighting up, do not use ignition liquids or flammable gasoline, diesel fuel, etc.
The principle of operation of the boiler Stropuva
After the flame has sufficiently flared up, it will begin to burn from top to bottom.
Both the original and the analogue of the Stropuva boiler work on the same principle. First you need to load the firebox with bitterness. Let's make a reservation right away that this can be done only after the boiler has completely burned out the previous supply of fuel, since the source of smoldering should be at the top. To start up the boiler you need:
- pull the ring and lift the telescopic air duct;
- remove ash through the lower door (1-2 times a week);
- fill the firebox with wood or coal, depending on the model of the unit (there are wood and universal ones);
- set fire to paper or cloth soaked in gasoline from above;
- lower the air duct and close the doors.
From one load of firewood, the boiler works a little more than a day, from a briquette - up to two days, and on coal - as much as five days.
As the fuel burns out, the air distributor moves down until it reaches the bottom. The air supply is controlled by a bimetallic plate. The developers have increased the efficiency due to the fact that an air heating chamber is built into the Stropuv boiler device. The latter enters the furnace at a temperature of about 400 degrees. At this temperature, pyrolysis gases ignite. But, unfortunately, the plate loses its properties and every month you need to make adjustments in the settings, and after a year, completely replace it with a new one.
Solid fuel boiler Stropuva design and principle of operation
Introduction
Solid fuel boilers Stropuva noticeably differ from other solid fuel heating devices and not only in their original color. Their design is also very unusual. Today we will try to figure out what advantages their design has and what disadvantages it has. And the real owners of Stropuva heating boilers will share their experience of using them with the readers of kotlydlyadoma.ru.
The history of the Stropuva boiler began in 2000 in Lithuania, when it was invented and patented. Since then, thanks to its original technology, burning duration, high efficiency and energy independence, these devices have taken a worthy place in the heating equipment market.
