Solid fuel boiler or brick oven. Which is better: a brick stove or a boiler? What to choose for home heating - boiler or stove

Private houses are being built not only in rural areas, but also in "one-story" areas of big cities. Gasification covers more and more settlements, so connecting the boiler to the gas main is not difficult. The only difficulty for the population is the payment for the development of the project, the passage of the procedure for its approval. This is done by competent employees of urban, rural and settlement gasification and gas supply services. Installation of gas equipment and related equipment is carried out only by specialists: any amateur performance in such a matter can be fatal.

Heating with gas using a boiler is gradually outpacing stove heating in popularity, but cannot completely replace it. Some people experience a panic fear of gas, as they have heard about the consequences of explosions, leaks and other troubles. They prefer the complex and cheaper process of laying stoves. The stove has always been an attribute of a cozy "house in the village." They slept on it, cooked in it, warmed themselves near it. At the same time, ensuring a constant supply of heat to the room completely depends on the activity of the one who is responsible for the quality of combustion of solid fuel. It is necessary to monitor the draft and intensity of combustion, clean the ash in time, clean the chimney, keep firewood and coal dry. It is possible and necessary to “program” heat transfer in the process of laying the furnace: the equipment of the so-called mirror (a heat-reflecting surface on the back wall of the furnace) is one of the conditions for efficient heating.

When arranging a gas boiler house, it is important to keep a record of fuel: it is necessary to install a meter and regularly check its technical parameters in accordance with the operating instructions. Preventive checks of gas equipment should be carried out annually and, at the slightest suspicion of a malfunction, call the gas service. Most boilers are equipped with an automatic shutdown of the gas supply in case of emergency, but this does not relieve residents from the need to remain vigilant. It is necessary to monitor the operation of the boiler in windy and rainy weather. It is advisable to be instructed by an experienced gas service employee. He will teach you how to operate a miracle technique, conduct a mini-exam on turning the boiler on, off and setting it up, and explain the nuances that may not be clear to a non-specialist.

Of course, everyone at the same time wants it not to require large material costs and physical effort, and to be warm and comfortable. And therefore, first of all, you need to carefully consider what kind of heating will be the most optimal for your home - a simple stove or boiler. And if a boiler, then on what fuel - solid, liquid, electricity or gas?

"There is nothing more reliable than a stove"

Furnace on two levels

Dashima Dugarova, a resident of Ulan-Ude, lives in a two-story comfortable house on Zelenkhoz. A house measuring 7 by 8 meters on two floors, approximately 110 square meters, is heated by an ordinary stove. The sides of the stove go to all rooms of the house. On the ground floor there is a large entrance hall, where the stove itself stands, a kitchen combined with a living room, a bathroom and a toilet. By the way, they are heated by electricity (warm floor. - Approx. "OB"). On the second floor there are two large bright bedrooms and a small hall.

When my husband and I thought about what kind of heating to choose, we thought that nothing was more reliable and cheaper than a simple stove, - the hostess of the house shares.

They believe that in any unforeseen situations: there is no light, electricity, gas or liquid fuel will rise in price, etc., the stove will never let them down. After all, we have no problems with firewood in Buryatia yet.

In the most severe cold, they heat twice a day: in the morning and in the evening, one firebox each. The house is reliably insulated from the outside and finished with metal siding.

During the winter, the owners burn one and a half or two cars of firewood.

"Zakamenskaya" stove

Ulan-Ude residents Svetlana and Aleksey Dorzhievs also adhere to their position in favor of the stove. They, unlike Darima, are only building their own house.

When we were faced with the problem of choosing heating, we, after consulting with relatives, chose a stove, after all, - says Alexey. - Building a boiler room with an expensive boiler, buying components for it, and these are pipes, and radiators, and an expansion tank, and so on, is beyond our means.

Initially, as they say, they wanted to install steam heating from the stove. Since the house is large, with a cut it turns out 11 by 14 meters. But then my friends advised me not to run pipes and radiators around the house at all, but to install an unusual stove, which they called “Zakamenskaya”, since the stove-maker from Zakamny. It differs from a simple oven in its size. It is only 25-30 centimeters wide, and three meters long, and it replaces the entire main wall. The stove will heat the hallway, kitchen, living room and one corner of a large dressing room. There is no heating in two bedrooms.

The doors of the bedrooms will almost always be open, the heat should come from the living room from the stove. But if it suddenly becomes cold in winter, then we will install additional electric convector-radiators. We will turn it on as needed, - says Alexey. - And in general, we'll see how the stove behaves, I hope we won't freeze. The people who installed such stoves do not regret it, and the stove-maker himself praised it.

Two stoves in the house

There are those in the republic who, in the old fashioned way, put two stoves in a big house, as Damdin Erdyneev, a former resident of the Yeravninsky district and now a resident of Ulan-Ude, did.

He moved to the city a house that he built for the family back in the late 90s, it is 14 by 12 meters in size. Friends laugh, they say, a whole gym, - says Damdin.

According to him, he did not carry out any heating, but simply installed two simple stoves. He wintered one winter and does not complain about the cold.

Firewood, of course, takes a lot, after all, two stoves, but it's still better than messing with the boiler room. There is a lot of trouble, taking care of the entire heating system, and you can’t turn it off in the winter cold, because everything will freeze. And the stove can be left at any time, and if necessary, flooded, - Erdyneev believes.

In the next issue, we will talk about which boiler is better to choose for your home. Our readers will also share their experience, talk about the advantages and disadvantages of different boilers.

Dear readers!

Why is a brick boiler better than a steel one? Are there any undeniable advantages? After all, for some reason, people everywhere use purchased metal boilers in their heating systems.

No, not everywhere. Quite the contrary everywhere. Especially in houses of old buildings - brick stoves are everywhere. As for new buildings, it is true that at first people try to assemble a heating system, as it seems to them, simpler. I calculated with the managers, chose the solid fuel boiler that I needed, installed it, launched it ... And everything is fine?

But no. It turns out that it is necessary to heat it almost around the clock, there is too much fuel and the suspicion is growing stronger that he made a mistake in choosing that the efficiency of this boiler is simply no. In addition, chimneys quickly become overgrown with soot, and you often have to clean it.

However, not everyone, even to himself, confesses his suspicions, praising his choice right and left. But there comes a moment when the question arises that something needs to be changed. And first of all, as a rule, the idea comes in addition to a solid fuel boiler to install a heat accumulator.

We will not talk here about the fact that again nothing happens, that there is no desired effect with a heat accumulator or it is scanty. Simply because the selected boiler does not develop the required power. In the end, they come to the conclusion about replacing the boiler with a more powerful one.

But here, there is no need to prove anything. If you take a calculator and calculate how much, then a 110 kW brick boiler turns out to be much cheaper than a steel boiler of the same power. And not only cheaper, but also much more effective.

Why is it more efficient? Because its design allows the most complete combustion of fuel. And this, accordingly, increases, since less fuel is needed to generate the same amount of fuel heat if it is completely burned out.

But what does incomplete combustion mean? Soot formation is incomplete combustion of fuel, since one of the components of any hydrocarbon fuel - carbon - does not burn out, but remains on the walls of chimneys in the form of soot.

What else is efficiency? The fact that a brick boiler is better. The generated heat is maximally transferred to the coolant, and the cooled gases go into the pipe. Chilled to a degree that still allows sufficient traction to be present.

Site search.
You can change the search phrase.

In addition, the brick boiler itself is a heat accumulator, capable of accumulating a considerable amount in its array, sometimes sufficient to heat a small house during the day. This accumulated heat is heat in addition to that which was given to the coolant.

Thanks to this property, the volume of the water heat accumulator can be significantly reduced. For an average house with a heated area of ​​​​100-150 m 2, the volume of the water accumulator can be halved, to 1 m 3. And this, as a result, another reduction in material costs and saving space in the room.

So, the choice of a solid brick boiler in comparison with a metal boiler is always in favor of the first. Because:

• brick cheaper;
  Compared to any metal boiler of the same capacity, the costs can be more than three times lower.
• brick has higher efficiency;
  It is achieved by the design of the furnace, which ensures complete combustion of the fuel, as well as more efficient heat exchange with the coolant.
• with a brick heat accumulator is cheaper.
  Since the boiler array also accumulates heat, this heat is given off to the heat carrier long after the boiler has been heated and closed.

If solid fuel is chosen for heating a house for one reason or another, then the homeowner faces the problem of choice: what type of heating equipment to prefer - a stove or a boiler? The old and proven old-fashioned method of heating, of course, carries a bit of retrograde, but, nevertheless, is still alive, and moreover, is not going to leave the stage. Of course, we are talking about traditional ovens. However, now furnaces are increasingly being replaced by solid fuel boilers, which have a number of advantages over furnaces. It cannot be said that boilers provide a colossal advantage, but it is still more convenient and profitable to deal with them.

Today, more and more often, owners of suburban housing are trying to insure themselves with autonomous heating systems. And this is quite reasonable, because if a gasified house is left without blue fuel in winter, life in it will become impossible. Another thing is if there is a stove or boiler, the fuel for which can always be obtained in the countryside.

At the same time, a solid fuel stove or boiler is often the only available means of heating, since the cost of connecting to a gas main can exceed all reasonable limits. So almost forgotten furnaces are recalled, which make it possible to receive heat in exchange for solid fuel with a guarantee. But it is even better to purchase a modern solid fuel boiler. Its superiority is undeniable, and in this article it will be proved in the course of an objective comparative analysis of all aspects.

Let's start with territorial preferences. First of all, let's define a furnace. It is a heating device in which, due to the release of heat in the process of burning wood or coal, massive walls are heated, transferring heat to the room. The oven is by no means an inefficient device. The designs of some models of furnaces allow you to take away most of the generated heat (efficiency up to 90%), although the human factor matters in this matter, namely, the skill of the stoker. Do not forget that the most common solid fuel stoves have been heating huge palaces for centuries. Modern dwellings are more modest in scale, and it is more than realistic to solve the problem of heating with the help of stoves, especially if there is always someone in the house to throw firewood into the firebox.

However, stove heating can be recommended not to any cottage. It is believed that it is advisable to use the stove for heating only small houses, the area of ​​\u200b\u200bwhich does not exceed 70 m². Exceptions are furnaces of special designs - Buleryan and Kuznetsov systems. The efficiency of such stoves is so high that they can heat an area of ​​150 m² or more. Buleryan's stove has a relatively simple device, and its appearance can claim to be an art object. In fact, this is a modernized potbelly stove. Made of metal, it can cope with the heating of a small house, and help out a large cottage in case of problems with gas supply. The body of the Buleryan stove is wrapped with pipes in which the room air is continuously heated. The circulation of air inside the pipes occurs naturally due to convection.

In Kuznetsov's furnaces, the stake is made on the use of a special mechanism for moving burning gases under the influence of their own gravity. The stone walls of the structure under conditions of increased pressure and the constant presence of turbulence perceive heat more strongly. In turn, this leads to an increase in the efficiency of the furnace and, accordingly, lower fuel consumption. Such stoves, like Buleryan, can decorate the interior and replace the traditional fireplace in the living room.

The boiler, unlike furnaces, is designed to heat the coolant, i.e. heating of the room with it does not occur directly. This allows you to heat rooms located at a distance from the main heat source. Theoretically, a solid fuel boiler, like a gas boiler, can provide heat to a cottage of any size. The coolant in solid fuel boilers is most often water, less often antifreeze or oil. They can work on wood, hard or brown coal, pellets, peat, etc.

The performance of the boiler is of paramount importance for comfortable heating of the cottage. As in cases with other heating equipment, a ratio of 1-1.25 kW per 10 m² of area is used to calculate the power of a solid fuel boiler. Accordingly, for a cottage with an area of ​​150 m², the boiler power should be 15-19 kW, and taking into account the power reserve, all 20-25 kW. A more accurate calculation of power, taking into account the degree of thermal protection of the building and a number of other factors, will be made by professional heat engineers.

From the point of view of the convenience of heating a multi-room cottage, boilers clearly outperform stoves, since they allow the heat of one source to be transported to all rooms. The only stove in the house is capable of this only in the case of a special layout.

Ease of installation of furnaces and boilers

Bake can be folded at any stage of building a house, however, in an existing building, its installation is very difficult. The only exception is metal furnaces such as Buleryan, etc., for the installation of which it is necessary to assemble an external or internal modular chimney. Typical projects are not suitable if heating is planned with a classic brick oven. Adaptation of the project will also be required for the Kuznetsov furnace. No wonder they say, "dance from the stove" - ​​the layout in projects with stove heating is carried out literally around the stove. The essence of such a layout is that all rooms have a common wall with an array of furnaces. In projects with furnaces, a foundation for the furnace is provided, as well as a passage through the floors and the collapse of the chimney.

Boilers do not require special planning and can be installed in an already built cottage. Moreover, if there is a gas boiler, they can have a common system. When switching from gas to solid fuel, you only need to let the coolant go to another boiler by switching the corresponding valves. True, you cannot put a boiler in the living room or in the dining room - you will need to allocate a separate room for it. The height of the ceiling in the boiler room for a solid fuel boiler must be at least 2.5 m, while natural lighting is calculated in accordance with the ratio of 0.03 m² / m³. If such a boiler room is located in the basement or in the basement, then a separate exit to the outside will be required. Finally, the boiler will need to be connected to the chimney; the boiler room itself must be ventilated. The area of ​​the smoke channel is calculated by a specialist. The chimney can be external (mandatory insulated) or internal (with thermal insulation and / or lined with bricks).

Obviously, installing a stove in a house is more complicated than installing a boiler. In addition, it is quite difficult to find a truly good specialist who can implement the furnace part of the project today. At the same time, many specialized companies are engaged in the installation of boiler equipment.

Furnaces and boilers in operation

Any solid fuel heat sources are inconvenient because they require periodic loading with fuel and cleaning the ash pan. Automatic fuel supply can only be arranged in pellet boilers (boilers with automatic supply of firewood, coal, briquettes also exist, but they are considered not so reliable), but this does not relieve the need to clean the ash drawer. The price for energy independence and the relative availability of solid fuel is the physical maintenance of the boiler, which requires the presence of a person. If we talk about stoves that heat the cottage, then the laying of fuel must be repeated up to 7-8 times a day. Traditional stoves consume more fuel than modern solid fuel boilers. In addition, the latter are distinguished by a longer interval of work on one load. On average, 2-3 hours pass between fuel tabs. This became possible due to the increased volume of the combustion chamber, as well as the secondary air supply system for the afterburning of combustible gases emitted by solid fuel. Thus, the number of bookmarks of fuel in the boiler furnace can be reduced to 2-3 times a day, which is quite acceptable.

Modern solid fuel boilers can be equipped with control automation, which greatly facilitates the work of the stoker. But this system at the same time reduces the energy independence of the heating system, since electricity is used.

Solid fuel boilers have some differences, depending on the type of fuel used, so burning, say, coal in a boiler designed for burning wood is highly discouraged. There are universal boilers, but their cost is higher than highly specialized ones, and by 30-50%.

The most common and affordable solid fuel in Russia is firewood. For the operation of a solid fuel boiler that heats a cottage with an area of ​​150-200 m² per day, you will need 15-20 kg of firewood. Traditional ovens consume about the same amount. The most economical is the Kuznetsov stove, which consumes only 10-15 kg of firewood when heating the indicated area.

As for the issue of operation, the furnaces in this case lose slightly to the boilers, however, even here the championship does not belong to them. Boilers turn out to be cheaper and easier to install, provide more opportunities for heat transportation, are more convenient to operate and at the same time are not inferior to furnaces in terms of durability.
