Biofireplaces appeared on the market not so long ago; before that, electric fireplaces or gas units were popular. To install a gas fireplace in an apartment, you must obtain special permission, and if the apartments are located above the tenth floor, then their installation is completely prohibited. There is no question of real wood-burning fireplaces; their installation is permitted only in in the rarest cases. will become the center of attraction in any apartment, they will make it comfortable and will be a real highlight, especially since their installation does not require any permits, just make a drawing of the room and figure out where the fireplace will be.

Biofireplace is installation, with which you can enjoy the burning of fire whenever you want. There are several varieties of such fireplaces:

1. suspension;
2. floor;
3. built-in

Everyone can choose the size of the biofireplace according to their wishes, since the units can be either large stationary or small compact. The fuel block may also be different sizes, the choice depends on the parameters room and its interior. The styles in which fireplaces are made are very diverse. you can do it yourself using drawings, of which there are quite a lot on the Internet.

They differ from real fireplaces operating principle. To light them, firewood or coals are not needed; fuel is used, which has a simple composition and is poured into the block. They have a special heating tank for heating liquid. But use whatever comes to hand fuel is not allowed, such fireplaces can only operate on bioethanol. Bioethanol is made from simple alcohol and used since the 70s. The first such fireplaces appeared in Italy; they came to our market already modern and stylish.

Why biofuel is special

Bioethanol is pure substance which is not harmful to health human and ecology, you can make it yourself, since its composition is not complicated. Bioethanol is used for biofireplaces for a reason; There is whole line reasons:

• Its composition is very simple, and during use it does not emit harmful products combustion. Room and apartment will not be filled with strangers smells when using a biofireplace. Bioethanol does not form soot or burning, which is why it is much superior to kerosene and gasoline.
• Biofuel combustion products are carbon dioxide with water. With such fuel, there is no need for a chimney or increased ventilation to get rid of the smoke, since there simply won’t be any. When installing a biofuel fireplace, you should simply ventilate the room regularly; this will prevent carbon dioxide from accumulating in the apartment.
• The fuel contains alcohol, which is the result of the processing of various plants containing sugar. These can be bananas and potatoes, corn and wheat, beets and other products. Only after denaturing the standard the product goes on sale.

Bioethanol has a wide range of applications; it is used not only for fuel block in the fireplace, but also for the manufacture of fireboxes and candles.

You can buy such fuel in a specialized store, but if you have the time and desire, you can make it yourself. During manufacturing, it is important to observe safety precautions and exact amount ingredients, otherwise when burning the fuel will click and flash during ignition.

How to make biofuel yourself

To make good and safe fuel for a biofireplace, you need to prepare some ingredients:

1. standard, which is sold in a pharmacy;
2. highly purified gasoline.

The standard must be strong – 96%, and only purified gasoline is suitable, for example, it can be gasoline for lighters. Having the necessary components, you can quickly and easily efforts to prepare fuel.

• Per liter of alcohol you will need 50-80 grams of purified gasoline. The components must be mixed until smooth (at first they may separate). It is recommended to mix the components before use, then the gasoline will not have time to separate from the alcohol.
• Do-it-yourself fuel needs to be poured into an iron container or into a fireplace burner, after which you can light it and enjoy a uniform flame without any smell, soot or burning. During operation of the biofireplace, it is recommended that the window be open to allow carbon dioxide to escape.

Do-it-yourself biofuel no worse than store bought. If a fuel-burning fireplace burns for an hour, 0.4 liters of fuel will be consumed. With a 2.5 liter fuel tank, the fireplace can burn for about 8 hours without refueling.

Security measures

Biofuel must be used with caution, as careless handling can lead to burns and even fire. Before making fuel and using it, you need to thoroughly study the operating rules:

• When fuel is poured into the fuel block, the fireplace should be cold.
• If the flame is not extinguished, add the mixture is strictly prohibited.
• It's better if there is a block 1/3 full, Do not fill it to the brim, otherwise the entire fireplace may catch fire. It is better to extinguish the flame during operation, add liquid and re-ignite.
• To start a fire, you need to use tools which are included with the fireplace. You may accidentally get burned when using a lighter. Remember that bioethanol may ignite during combustion. Used for ignition long handled tools to protect yourself.
• Never use lighter paper, this also applies to wood and other flammable materials, their use is only suitable for wood fireplaces, but they are not suitable for a biofireplace block.
• If, through negligence, a flammable mixture spills, it must be wiped dry, no matter what the surface.
• Light a bio-fireplace contraindicated for children, it is better to store fuel out of their reach.
• When the unit is not in use, the bio-fireplace liquid must not be in the fuel tank.
• Before purchasing or making a bio-fireplace, you should consult a doctor to see if family members have respiratory diseases.
• Remove from

The emergence of biofuel is a logical continuation of the movement of manufacturers and trade in terms of ensuring the desire of customers who do not have the opportunity to install a full-fledged fireplace in their own home, to equip it with an analogue that is comparable in visual and olfactory effects.

First, electric fireplaces appeared, and then the so-called biofireplaces, in which it was no longer imitation, but real flames that “danced.”

And it doesn’t burn in them solid fuel, and a liquid specially developed for these purposes, called biofuel for fireplaces.

Biofuel consumption for the fireplace

Today, trade offers fuel for biofireplaces of several brands and in various packaging.

The following types of biofuels are most widely represented on the market:

• Art Flame. Sold in one and a half liter plastic bottles;
• FANOLA. Supplied to retail chains in bottles made of plastic with a capacity of 1 liter;
• “Bioheat” is a biofuel for biofireplaces, produced in Russia. It is offered to the buyer in five-liter plastic canisters.

The operating principle of all biofireplaces, which are classified as fireplaces that do not require the use of chimneys, is that work area In such a fireplace, a special burner is installed, which acts as its heat-extracting part.

The fuel for the bio-fireplace is poured here. Thanks to its design, the burner evenly distributes liquid from the fuel block.

The latter, depending on the design of the fireplace, are installed either inside the body or inside a niche (if it is a built-in fireplace model).

When purchasing a biofireplace, fuel consumption can be calculated based on the information specified in the passport for your biofireplace model, as well as on the label of the container with the biofuel you purchased.

Approximately:

• one bottle of Art Flame brand fuel (capacity 1.5 l) is enough to ensure continuous burning of the fireplace for 7 - 8 hours;
• The declared consumption of Bioteplo brand biofuel is 0.36 l/hour. Therefore, when filling a 2.5 liter heating unit, we will get a continuous burning time estimated at 8 – 10 hours.

Composition and characteristics of biofuel for fireplaces

The basis of any biofuel is alcohol obtained from plant raw materials - ethanol.

The manufacturing technology involves its production by fermentation of sugars found in some plant crops (wheat, beets, potatoes, etc.).

According to the provisions international law its sale in pure form prohibited for end consumers, so the alcohol undergoes denaturation.

The resulting denatured ethanol is completely neutral. When burned, it releases heat and decomposes into vapors of H2O and CO2.
Such products are harmless to the environment and humans, especially since the concentration of carbon dioxide does not exceed the value contained in the air exhaled by a person.

When storing and using biofuels, it is necessary to follow the safety measures recommended by the manufacturers of these types of fuel.

Remember, when using biofuel for biofireplaces, it is prohibited:

• keep the fuel container near an open flame;
• pour it into a heating unit that is working. Refueling is carried out only after the latter has been turned off and completely cooled (not earlier than ¼ hour after the flame has been extinguished);
• use straw, paper or other flammable materials for ignition. You can light the biofireplace only with the metal lighter included in its kit;
• store fuel outside the places intended for these purposes.

If you spill fuel, be sure to wipe the area with a napkin or special cloth.

The design of the heating unit and the composition of the biofuel itself prevent sparking, flame return, and the appearance of smoke, soot or gases hazardous to health.

One liter of fuel emits about 4 - 5 kW/hour during its combustion (which is equal to the operating efficiency of a pair of standard electric heaters).

Since it is practically not lost through movement through chimneys, etc., but completely enters the heated room, we can say that the efficiency of a biofireplace is over 95%.

Is it possible to make biofuel for fireplaces with your own hands? It is possible by mixing pharmaceutical 96% ethanol and aviation B-70 in a certain proportion. But it’s better not to do this and use factory-made biofuel.

Until recently, only owners could enjoy fireplaces country houses or private estates. Placing such a structure inside an apartment remained only a dream for a long time. Only thanks to the advent of biofireplaces, residents apartment buildings got the opportunity to enjoy live fire. You can install this type of heating device with your own hands in any room, regardless of its function and size.

What is a biofireplace?

A biofireplace is a kind of installation, which is a specific unit for biofuel. It is as a result of combustion that consumers can enjoy the picture of a live fire. Depending on the method and location of installation, biofuel fireplaces are divided into several types:

Do-it-yourself bio-fireplace installation diagram

• desktop;
• floor;
• hanging;
• built-in

Tabletop fireplaces are especially popular due to their compactness and mobility.

They differ in size, as well as in the possibilities of movement, for example, mobile and stationary. Thanks to the large assortment, you can choose the optimal biofuel fireplace for the interior of your home to highlight the design and style of your apartment.

The main advantage of such fireplaces is their operating principle. You can install the structure with your own hands and without additional help specialists. You don't need wood or coal to get a live fire. New generation fireplaces run on biofuel.

Main characteristics of biofuels

Fuel for a biofireplace is made from biological raw materials, which are obtained by processing biological waste or animal or plant raw materials. The material received its name as a result of the use of renewable plant resources, for example, natural waste, oils (palm, rapeseed), and grain crops.

In general, biofuels for fireplaces are denatured ethanol. As you know, ethanol is an alcohol that is obtained as a result of the fermentation process of crops with a high sugar content or in the process of hydrolysis of straw, wood or other types of raw materials with high level cellulose.

When burned, denatured ethanol has no negative influence on human body, animals or external environment. Alcohol produces carbon monoxide and steam, as well as a small amount of heat. Fire using bioethanol is characterized by even tongues, soot and smoke are absent.

This installation does not require an exhaust device, thereby retaining the resulting heat in full.

Features of biofuel for the fireplace:

• absence of carbon monoxide, soot and soot;
• fire does not have an orange tint, so special additives are added to the composition;
• absence of characteristic combustion odor.

The most popular manufacturers of liquid for biofireplaces are countries Western Europe(Italy, France, Germany), Canada, USA. Brazil became the leader in production.

Pouring biofuel into a biofireplace

Types of fuel for biofireplaces

Depending on the products used for production, as well as the characteristics of the raw materials, there are several most popular types of biofuels:

• biodiesel is a material obtained by processing fats (vegetable oils and food industry waste)
• bioethanol is an alcohol that is colorless and odorless, obtained as a result of the fermentation of carbons.
• biogas is a gas that is produced as a result of processing waste and garbage.

Choosing fuel for a biofireplace

To please yourself with warmth and comfort, you need to choose the appropriate biofuel for fireplaces. The result will depend on this: the color of the fire, the sharpness, the shape of the flames. When making a choice, it is important to consider the following details:

• liquid for biofireplaces must burn out completely;
• high level of thermal performance;
• availability of a quality certificate from research institutions.

Advantages and disadvantages

Consumers' most common concerns are fluid consumption and device operating efficiency. On average, about 500 ml of liquid is required per hour of combustion. And in terms of heat generation, the fireplace is in no way inferior to a conventional three-kilowatt heater.

Advantages of biofuel fireplaces:

• absence of negative combustion products;
• the ability to regulate combustion strength;
• lack of additional structures and equipment;
• reliability and fire safety;
• low cost.

Fireplace disadvantages occur when Not correct operation device. Therefore, you should remember:

• You can add fuel only after the fireplace has been completely extinguished and cooled;
• keep liquid away from fire;
• Light a fire only with a special lighter.

Application

The composition must be poured into a specially designed block and set on fire. A 5-liter canister of liquid is designed for 20 hours of burning.

If the fuel is in the form of a gel, place the cans among firewood or stones and light them. You can stop the burning process by screwing the lids on the jars of gel with your own hands.

How to prepare biofuel with your own hands?

If it is not possible to purchase biofuel, but you really want to try a fireplace, you can prepare the mixture yourself. Initially, protect yourself from accidents - remove carpet covering and protect skin and eyes from possible contact chemicals. What does it contain?

To prepare the mixture with your own hands, you need to purchase ethanol (96%) and gasoline, which is used for lighters. Mix the ingredients in such a ratio that part of the gasoline is 6% in total number fuel.

Biofireplaces - perfect option for those who have a small living space. You should not give up the natural beauty of the elements of fire, coziness and comfort, especially since installation and connection can be done with your own hands.

Video: How to make biofuel with your own hands

Biofireplace - variety modern line decorative elements interior The flames are real and no chimney is required. Therefore, you can install a bio-fireplace anywhere, even hang it on the wall in your apartment. This happens because the fuel used for the biofireplace is the most natural, natural, and therefore safe. It does not smoke, does not smoke, does not produce sparks and does not emit bad smell. Its combustion occurs completely, without waste.

Features of biofireplaces

This device is not heating device. They differ significantly from electric fireplaces, which, in addition to their decorative function, also heat the room, while drying out the air and consuming quite a lot of electricity.

The technology for producing a biofireplace is not too complicated. You can make it yourself, as long as your imagination works in the right direction. The basis of any such device is a container for biofuel and a decorative box.

The fuel container is equipped with a burner and a lid. To put out the fire, just lower it. The shape of the container is selected depending on the design concept and can be any - round, square, pyramidal.

Decorative box must be closed It is firmly attached to permanent place. However, if you like looking at an open flame, you can make something original from a fireproof glass container.

Fire in fireproof glass looks stylish and fascinating.

Fuel

The main component of the working fluid for a biofireplace is alcohol, but not medical alcohol, but produced from natural components (ethanol) with the addition of denatured alcohol or purified gasoline and other additives in a non-medicinal form. large quantities. The basis of ethanol is root vegetables and plants containing large quantities of starch or sugar. Thus, biofuel for fireplaces on an industrial scale is produced from:

• corn;
• cassava tubers;
• beets;
• sugar cane;
• potatoes;
• sweet potato;
• sorghum and barley.

Good raw materials are rice and wheat straw, plant residues from sugar cane production, and sawdust.

Products from which ethanol is distilled.

Fuel for biofireplaces is produced in industrial conditions different ways: hydrolytic, via fermentation. The first was used exclusively in the USSR, the second was and is used in other countries, and currently in Russia.

The production technology consists of several stages:

1. The raw materials are prepared and cleaned of foreign impurities.
2. It is loaded into special containers for fermentation. The process requires the addition of yeast. They convert the starch contained in the raw material into ethanol.
3. Bragorectification or purification of the resulting liquid from fusel oils.

Benefits of ethanol

The prefix bio indicates that when it burns (combustion) it does not emit harmful substances, smoke, soot and soot do not settle on surrounding objects. All that gets into the air is water vapor and carbon dioxide. When the bio-fireplace is operating, it is necessary to ensure the flow into the room fresh air. For the cold season the best option There will be slot ventilation.

Thus, the advantages of biofuel for biofireplaces are as follows:

1. When used correctly they are completely safe.
2. When burned, pure water vapor and CO 2 are released.
3. The appearance of the fire is very ordinary, as if real wood was burning.
4. The cost is affordable for the average consumer.

Ethanol burns with a blue flame, and real firewood burns with the tongues of the most different colors- orange, yellow, blue. To achieve maximum similarity. Special additives are added to industrial biofuel. Achieving the same effect for homemade mixtures is problematic.

Ethanol-based biofuel is used not only in biofireplaces.

Making your own fuel

The cost of finished ethanol is low. However, for craftsmen who are accustomed to making everything with their own hands, it will be useful to know that biofuel for biofireplaces can be made with their own hands. Its production process involves some risk of accidental fire. Therefore, you should not take risks if you can purchase the mixture in the store.

Do-it-yourself biofuel for a fireplace can be made in two ways:

1. Buy medical alcohol (96%) and combine it with purified gasoline (aviation grade, marked B-70, it is used in lighters).
2. Producing alcohol yourself, which is quite expensive and time-consuming, since a high degree of purification is required. With conventional fermentation, ethanol with a strength of only 15% is obtained. It depends on the yeast. At a higher strength they will simply die.

Therefore, the second option remains only for ardent fans of distilling alcohol. Do-it-yourself bioethanol is easy to prepare from two ready-made ingredients:

1. Take 9 - 9.4 parts of alcohol and 0.6 - 1 part of aviation gasoline.
2. Gently mix both liquids.
3. Pour into a biofuel container and light it carefully.

Consumption is economical, only 0.1 liters per hour. Store fuel in a plastic container or canister (depending on the volume produced). Be sure to stir before pouring into the fuel tank. During storage, the liquid separates.

Advice. Do-it-yourself fuel for a biofireplace is best made using outdoors. Take care of protective equipment - put medical gloves on your hands, cover your nose and mouth with a medical mask. Mix the two liquids in a tightly closed container. Pour them into it through a plastic funnel. Test the finished liquid for a bio-fireplace also in the open air.

Subtleties of working with fuel

Ethanol burns in the same way as gasoline or kerosene. Therefore, when working with it, in particular, when filling the fuel tank in a biofireplace, you must observe the following precautions:

1. Storage of containers with industrial fuel is carried out in a room located as far as possible from sources of heat and possible fire, in tightly closed containers. The same requirements apply to homemade mixtures. After mixing, they need to be poured into clean canisters, sealed and taken away from children's eyes.
2. When filling the fireplace tank, pour required amount mixtures in plastic dishes. It is advisable that its neck be equipped with a protrusion for easy pouring. Refill the tank using a plastic funnel.
3. If fuel gets on the fireplace or floor, remove it with a rag. Wash the area with soap and water and wipe dry. Throw away the rags as they may accidentally ignite.
4. The tank can be replenished both when the mixture is completely burned out, and when there is a certain amount of it in it. To do this, extinguish the flame (lower the lid on the burner), wait until it cools completely and only then proceed to refuel.
5. If fuel gets on your hands, wash them with soap.
6. In case of accidental contact with eyes, rinse them with plenty of water and consult a specialist.

Biofireplaces can operate on different biofuels. In addition to liquids, these can be gases and hard materials. It is much easier to obtain biogas and solid fuels than pure ethanol.

Natural gas is a mixture of CO 2 and methane (up to 70%). This is a flammable and explosive compound. However, many people obtain it quite successfully at home, for example, from horse or cow manure mixed with plant residues and water.

Gasoline used for self-preparation of liquid biofuel must be clean, transparent, and odorless. Never experiment with car fuel!

To make a biofuel fireplace look completely real, special ceramic firewood is produced. They can look like they were just thrown into the fire, or like they were burnt. Place them in the hearth, sprinkle a couple of drops of fir oil and light the fire. Everyone will think that your burning wood is natural.

You can make your own biofuel for a fireplace without any problems. But is it worth doing this, or is it still easier to purchase ready-made liquid in a specialized store? Everyone has their own answer to this question. Remember, the production of homemade liquid allows you to realize some of your own interests or ambitions, but at the same time poses a certain danger to life and health.

Biofuel is made from natural raw materials based on waste products of organisms. Products of plant and animal origin, which are obtained by processing biological waste, can be used in the production process. Biofuel for the fireplace is best view fuel, which does not require a chimney.

The material used is for eco-fireplaces. The use of renewable plant resources in production gave the prefix “bio”. Fireplace fuel is denatured ethanol, which is based on ordinary ethanol. This ingredient is an alcohol that is obtained by fermentation of plant sugar-containing crops, including:

• potato;
• beet;
• wheat;
• cane sugar.

Get pure alcohol It is also possible through the hydrolysis of raw materials that have a high cellulose content. Examples include wood and straw.

Biofuel properties

Ethanol in the process of denaturation acquires the properties of a neutral effect on environment. The material does not have a harmful effect on the human body, and its combustion is decomposition with the formation of some heat, steam and carbon monoxide. When biofuel is used for a fireplace, it is possible to obtain even, beautiful tongues of fire.

The fuel is safe, odorless, does not produce smoke and burns without soot. This eliminates the need to install a smoke hood. The heat is not lost, it remains in the room. All this indicates that the efficiency is 95%. If we compare appearance the flame that is produced by the combustion of biofuel and that produced by the combustion of logs, there are almost no differences. Biofuel is used in the form of a gel, which has sea ​​salt in the composition. It allows you to achieve the characteristic crackling sound of firewood.

Types of biofuels

Biofuel for fireplaces is produced today en masse in Europe, Northern and South America. Brazil occupies a leading position in ethanol production. All biofuels produced in the world can be classified into several types, including:

• biodiesel;
• biogas;
• bioethanol

Biodiesel is obtained from vegetable oils, biogas is a kind of analogue natural gas. It is made from waste and garbage that undergoes special treatment. As for bioethanol, it contains alcohol and is a substitute for gasoline. If you need biofuel for your fireplace, you may want to take a closer look at biodiesel. It is based on processed vegetable fats of animal and microbial origin. The following oils are used as raw materials:

• soy;
• coconut;
• Palm;
• rapeseed

Food processing waste can be used in production. The development is based on the technology for producing biodiesel from algae. In Europe, the most commonly used biodiesel is oil-based.

Composition of bioethanol

Liquid biofuel for fireplaces can be represented by bioethanol. This is an alcohol that is obtained during fermentation from carbohydrates. The latter are found in corn, sugar cane, sugar and starch. The raw materials for production are trees, grasses and other cellulosic biomass. If you decide to use bioethanol, the product will be a colorless liquid that is odorless.

Features of biofuel

When burned, biological fuel does not produce carbon monoxide, and there is no soot or soot. When working with fuel, fireplaces emit such an amount of soot, the volume of which is no more than when burning a regular candle. If ethanol is used as fuel, its combustion is accompanied by the release of only water and carbon dioxide. Therefore, the flame does not have the traditional orange hue.

In order to achieve naturalness, the described types of fuel are supplemented with additives. Thanks to them, the fire acquires Orange color and looks more natural and rich. Biofuel for fireplaces, the composition of which was mentioned in the article, can be used as an energy carrier to operate lighting devices. For example, a kerosene lamp, working together with biofuel, will not emit soot, there will be no smell, and if you use kerosene, then such consequences cannot be avoided.

Biofuel production

If you want to use a biofuel fireplace at home, you can make a means for its operation yourself. Many pharmacies today offer ethanol, the concentration of which ranges from 90 to 96%. Liquid fuel It’s quite easy to make based on it. For painting, you can use household purified gasoline, which is often replaced with lighter fuel. If you want to make sure the quality, you should check how transparent the product is and whether it has a smell.

In order to make biofuel for the fireplace with your own hands, you should add about 100 g of gasoline to a liter of alcohol. The composition is mixed, and it is recommended to use it immediately, since after some time the ingredients will separate. With this type of fuel, fireplaces operate without hoods or chimneys; however, the room should still be ventilated from time to time, this will eliminate the lack of oxygen and excessive humidity.

Consumption and efficiency

As practice shows, the efficiency of biofuels is approximately 95%. If you use odorless bioethanol, its average consumption per hour will be approximately 0.36 liters. If you burn 1 liter of the substance, you will be able to obtain approximately 5 kWh of thermal energy. If we compare an eco-fireplace with a 3 kW electric heater, then these devices are similar in efficiency. But the first will additionally humidify the air, while the second, on the contrary, will dry it.

If you want to get a natural-looking fireplace, then you should purchase a model with artificial logs. They are usually made of fire-resistant ceramics, and when exposed to elevated temperature start to turn red. Biofuel fireplaces, photos of which you can see in the article, can work by releasing the aroma of pine needles. To do this, use a few drops essential oil. When burning, you will see a bluish flame, which is true for plant-based biofuels.

Advantages and disadvantages of biofuels

A biofuel fireplace without a chimney can be purchased today at any relevant store. Such equipment runs on a special substance, which has some pros and cons. For example, efficiency and consumption are the factors that concern consumers first. In just one hour of operation, a modern biofireplace will burn 500 ml of fuel. The amount of heat generated will be equal to 6.58 kWh per liter of biofuel.

In terms of efficiency, such equipment is quite attractive. Among the additional advantages is that biofuel is a clean product from an environmental point of view. You can regulate the combustion. The use of additional hoods and other expensive equipment is excluded. Burners can be easily cleaned after burning biofuel.

The biofireplaces themselves have reliable thermal insulation of the body, so during operation they have demonstrated fire safety and reliability. If necessary, the equipment can be dismantled and assembled in the shortest possible time. Bioethanol is easy to transport. Heat transfer will be 100%, because there is no heat loss. There is no need to prepare firewood; dirt and debris will not form in the house. Combustion prevents the flame from returning. Fuel is affordable, which is essential for the family budget.

Among the disadvantages, only minor details can be identified; they are expressed in the fact that biofuel cannot be drained while the fireplace is operating. It is not permitted to store the substance near an open flame. It is not recommended to light fuel using logs or paper; special iron lighters are available for sale for this purpose.

Conclusion

Biofuel is used today for fireplaces that are used in indoors without ventilation outlets and chimneys. This has expanded the scope of use of devices that can be installed in an apartment, office or country house.
