Briquettes for kindling are made from waste from the woodworking industry, that is, from sawdust and shavings, as well as food waste, for example, from rice husks, buckwheat or sunflower seeds. There are vegetable briquettes that are made from straw or dry grass and coal dust briquettes. It is difficult to say which briquettes are better, since each type has its pros and cons.

Briquettes are also called Eurowood, and among themselves they can differ in shape and maximum compression density of the material. Regardless of these parameters, all briquettes can boast the following advantages:

1. High level of heat transfer - due to the high density of the material and its low humidity, one briquette can burn for up to 4 hours, while generating more heat than simple wood firewood of the same size.
2. Compact storage - briquettes not only take up relatively little space, but also have the correct geometric shape, thanks to which it is much easier to fold them than firewood.
3. Waste-free - when briquettes are burned, very little smoke is released, and after them no more than 10% of ash remains.
4. Versatility - suitable for all types of boilers and stoves, and can also be used for making a fire in nature.

The main disadvantage of this option is that the briquettes take a long time to warm up and, when burned, emit a not always pleasant smell. In addition, they need to be stored in special conditions, since they can crumble from high humidity or mechanical stress. And if you need a bright and large flame, then this is definitely not about eurowood, since they smolder rather than burn.

And straw briquettes emit a lot of soot, so when using them, you will have to think about cleaning the chimney much more often than usual.

Firewood - a voluminous classic

Firewood is the oldest material used for space heating. They can be made from various types of wood, and this depends on some individual characteristics, but all types of firewood have the following advantages:

1. They light up quickly - therefore, they are a convenient option if you need to warm up the room as soon as possible.
2. They are inexpensive - the cost of kindling a boiler or stove with firewood can generally be minimized if you prepare them yourself.
3. They are unpretentious in storage - wet firewood can be dried (although this is a rather long process) without losing their performance, and they are insensitive to mechanical damage.
4. If you use firewood from some types of wood, then when burned, they will release essential oils that have a beneficial effect on health.

The disadvantages of firewood are obvious - they take up a lot of space during storage, when they burn, a lot of ash remains, and if the wood is also wet, then it burns badly and gives a lot of smoke.

And yet - firewood or briquettes?

What is more profitable? The answer to this question depends on what exactly you intend to use the fuel for. If we are talking about stoves and boilers for long burning, then it is preferable to use briquettes. If you need fuel for an ordinary stove, or even more so for an open fireplace, which will not only generate heat, but also burn beautifully, then well-dried firewood is in the lead.

The nuance also lies in the purchase price and storage conditions. Firewood is sold in cubic meters, and because of their irregular shape, you buy not only the fuel itself, but also the air. Also, for drying and storing firewood, you need a properly equipped place where you have to place a woodpile.

Briquettes are sold in packages by weight, which excludes the purchase of air, and it is much easier to store them.

Briquettes are more compact and give more heat, but they are more expensive, and firewood is cheap and gives a beautiful bright flame.

Decide which of these parameters is more important for you and you will easily get an answer to the question which is more profitable - firewood or briquettes and what is the best way to heat your boiler, fireplace or stove.

Despite the widespread laying of gas pipelines, there are still many settlements and places in Russia where there is simply no gas. People have to use alternative heat sources such as solid fuel boilers. These units run on wood, but recently more modern types of fuel have begun to be produced for them - these are fuel briquettes for heating stoves. Let's take a closer look at them and find out their advantages and disadvantages.

In this review, we'll look at:

• Disadvantages of classic firewood;
• Fuel composition;
• The main types of briquetted fuel;
• Pros and cons of oven briquettes.

After reading the review, you can make a choice in favor of traditional firewood or in favor of a more modern briquette fuel.

Heating stoves with wood

Wood-fired heating stoves provide efficient heating of residential and non-residential premises. They are presented in many models, differing in their technical characteristics and device. They use ordinary firewood as fuel - they can be purchased with whole trucks. But this fuel cannot be called modern and efficient. And today it has been replaced by fuel briquettes for heating stoves.

In order to be clear, consider the main disadvantages of traditional woodfuel:

Ordinary firewood must first be chopped, and then also put in neat woodpiles. This is a very laborious and time-consuming process.

• It is inconvenient to put firewood in neat masonry - if they are of the same size and format, then this is not so bad. But if some logs are thin, while others are thick, and even knotty, then the masonry will be crooked and oblique (although much depends on the “curvature” of the arms);
• Firewood needs to be chopped - they are often supplied in the form of round blocks that require felling. Swinging an ax in cold weather is a dubious pleasure (albeit useful);
• Firewood is often damp - in an effort for their own benefit, lumberjacks sell the wood in a raw state, without prior drying. Compared to almost dry fuel briquettes for heating stoves, it will not be easy to ignite them;
• Low calorific value - a cubic meter of firewood gives less heat than the same wood briquettes of the same volume;
• Firewood gives a large amount of ash - the same wood briquettes practically do not clog the stoves;
• The wood burns with clicks and crackles, burns unevenly, obviously losing in this to briquettes.

Firewood is the most common and cheapest solid fuel for heating furnaces and boilers. But fuel briquettes outperform them due to convenience and high calorific value.

What are fuel briquettes made of?

Wood fuel briquettes are made from wood waste - roughly speaking, these are pressed sawdust that has undergone a certain preparation. The preparation process includes grinding and drying. As a result, raw materials are born, ready to go under the press. Some sawdust does not need drying at all, as they are almost dry.

Most often, this type of fuel is produced from ordinary sawdust.

Safe organic compounds act as binders in fuel briquettes for furnace firing, and some types of Euro wood are made without an adhesive base. The prepared raw materials are sent under the press, forming dense neat bars, ready for further use. As an additional treatment, firing can be used - it all depends on the manufacturer and the technologies he uses.

The resulting wood briquettes for heating stoves are sent to consumers - they are suitable for heating houses and non-residential buildings, used for kindling fireplaces. They can also replace firewood at a picnic, but in this case you will not hear the sound of crackling firewood. But you will get an even flame, without scattering coals and sparks.

Advantages and disadvantages of fuel briquettes

Let's see what are good fuel briquettes for burning stoves, and what are their main pros and cons. Let's start with the positives:

• Convenience of storage - thanks to its neat shape, eurowood and other briquettes can be folded into neat, even masonry;
• High calorific value of fuel briquettes - if you compare them with ordinary wood, they give one and a half to two times more heat. Due to this, you can save on fuel when firing furnaces and boilers;
• Briquettes are long burning fuel for all types of stoves. Pressed sawdust burns one and a half to two times longer, reducing the number of approaches for filling new portions of fuel. If there is an ordinary stove in the room, burning on wood for 2-3 hours, then with fuel briquettes this time will increase to 4-5 hours;
• Uniform combustion, without unnecessary noise and embers shooting in all directions. In addition, the fuel briquettes used to fire the stoves emit less smoke and produce less ash, reducing labor costs for cleaning;
• Low tar formation - due to this, chimney clogging is reduced;
• The duration of storage of fuel briquettes for heating furnaces varies from 1 to 5 years - it all depends on the manufacturing technology;
• High environmental friendliness - no chemical reagents are used in the production of briquettes;
• The volume of briquetted fuel consumed during one heating season is 1.5-2 times less than the volume of firewood used during the same time period.

Fuel briquettes intended for heating stoves burn smoothly and softly, with the release of a large amount of heat. They do not clog stoves and chimneys, they burn out by almost 99%.

If your house has a long-burning stove or boiler, then you will feel an additional advantage from using briquetted fuel - the burning time will increase by another 1.5-2 times, reaching 12-16 hours or more (depending on the model of the equipment used).

Unfortunately, it was not without certain drawbacks:

• Fuel briquettes used for heating furnaces are not afraid of dampness. Wherein they still do not like direct contact with water;
• Some types of briquetted fuel do not tolerate long-term storage - their shelf life is limited to one year from the date of manufacture;
• The cost of purchasing fuel may be higher than purchasing ordinary firewood - it all depends on the manufacturer;
• In some regions and settlements, it is more difficult to purchase fuel briquettes for heating boilers and stoves than buying a truck of ordinary firewood;
• Cost - it is slightly higher than the cost of ordinary firewood. But due to the high calorific value and long burning time, you can save a little.

Despite all this, briquetted fuel continues to gain its popularity.

Popular types of wood briquettes

We have already talked about the manufacture of fuel briquettes for heating boilers and furnaces, as well as their key advantages and disadvantages. It remains to figure out what types of briquettes are presented on the domestic market.

This fuel resembles white or wood-colored bricks in appearance (the shade varies widely). RUF briquettes are made from dry sawdust by pressing under high pressure. As a result, Eurowood is born that can be used in any type of oven. Their distinctive feature is the RUF lettering, embossed on both sides at once.

Fuel briquettes RUF for heating furnaces are characterized by the release of a large amount of heat - they are almost one and a half times more profitable than firewood... It is easy to load combustion chambers with them and store them in stacks. Pressed bars are not afraid of moisture, but it is also not necessary to expose them to direct contact with water. This fuel is supplied by many manufacturers - a typical example of this is a company called Olezhka. By the way, it also sells many other types of solid fuels.

An interesting feature of these Euro briquettes is their unusual shape - they resemble square pencils, from which someone took out a lead. Therefore, they are called "pencils". In order for it to burn with the release of a large amount of heat, a hole is made in it to increase traction. The "pencils" themselves look dark as they were fired. This procedure makes them more durable and removes excess moisture.

The disadvantage of PINI KAY fuel briquettes for heating stoves is that they are more expensive than wood and even more expensive than any other types of fuel. But they burn well, emitting a large amount of heat. It is also convenient to transport and store them. Thanks to their shape, they are ideal for kindling fireplaces. Some people take them with them to the countryside to use PINI KAY bars instead of firewood.

Simple cylindrical briquettes

The simplest fuel briquettes for heating furnaces are also on sale - in the form of cylinders. They are made from pressed sawdust and small wood waste. All this is pressed under low pressure using a non-toxic adhesive base, after which the finished bars are sent to consumers. This fuel is cheap, but has one pronounced drawback - low strength. It easily disintegrates and crumbles, does not withstand moisture.

Fuel briquettes from coal and peat

Peat and coal fuel briquettes for the heating of the stove are made, respectively, from peat and coal. The starting materials are molded into small cylinders. The fuel can be used to light up stoves and solid fuel boilers. Coal products give a high combustion temperature, but are characterized by high ash content... As for peat fuel, it is perfectly suited for long-burning stoves, but it also gives a lot of ash.

If you have a stove that needs to be heated with something, we recommend that you choose PINI KAY or RUF fuel briquettes. They are distinguished by their convenience and high calorific value, form a minimum of ash and ensure long burning.

It's nice to throw a couple of pine or oak logs into the fireplace. But what is interesting, fuel briquettes, which are pressed from wood chips or bark, are superior to wood. Not in the aesthetics of the combustion process, but still in very important parameters - in terms of heat (calorific value) and duration of burning. Let's figure it out how is it possible?

Key indicators of fuel are calorific value, which depends on the organic matter content and moisture content of the fuel. Fuel density is also of great importance. It turns out that 1 ton of dry (3-4% moisture) briquettes = 5 tons of firewood (moisture 20%).

The moisture ratio determines the higher calorific value. And the more moisture the wood has, the more combustion energy is spent simply to evaporate water from the wood!

Fuel briquettes are made using high pressure (300 atmospheres). They create a briquette with a very high density, a couple of times higher than that of a tree. As a simple manifestation - this is an experience, throw a fuel briquette into water - and you will see how it dashingly goes to the bottom! That is, its density is higher than the density of not only wood, but also water. The density of a briquette is 2-3 times higher than that of wood. And the density determines the duration of the combustion process.

The briquette can burn up to 5-8 hours, and as a norm it has a burning time of 2-3 hours. For a stove fire or for a fireplace, a longer burning time is good. You can put briquettes and not toss up fuel until morning, the fire will remain for the whole night.
In ordinary wood there are pores with oxygen and due to this it burns quickly, and the briquette will burn slowly and give more heat than wood.

And some briquettes due to the shape - it is very convenient to fold. Such briquettes, I remember as a curiosity shown on TV in a report about Japan, that they make an excellent fireplace fuel from waste. It was back in the 90s of the last century.

Knowing these secrets about humidity, you understand why it is very important to have long-term aging firewood in the household - which, when naturally dried, reach low humidity, and besides, always have a supply of firewood near the fireplace itself and near the stove in the bath. So that they dry out well. This will seriously reduce the heating time of the sauna - to a high temperature in the steam room.

Calorific value:

firewood of natural moisture (40-55%) ~ 1500 kcal / kg

dry firewood (moisture 25%) 2160 kcal / kg (pine), 2600 kcal / kg (birch)

brown coal 3910 kcal / kg

briquettes from wood waste 4400-4500 kcal / kg

black coal 4900 kcal / kg

When burning, briquettes do not emit burning, fumes or soot. When burning, they do not spark or smoke. When burning, it gives a high-temperature flame, so it can be used in a workshop where the temperature must be maintained for a long time.

The advantage over conventional firewood is the low ash volume. Ash content - the percentage of ash remaining from the combustion of briquettes 1% of the mass of used wood briquettes.

But in conclusion, it is also important to dispel the fear - “We know that glue is used in the same place, all these sawdust should be glued into briquettes.” Bonding into a single object is achieved due to the fact that part of the “Lignin” wood under the influence of temperature turns into an environmentally friendly binder.

Fuel briquettes are sold in supermarkets in packages, usually 10 kg each, and the price for them is not small - 7 rubles per kilogram. They are convenient to be “under our feet”, we stumble over them, buying sausage and potatoes, and they are also quite clean, do not give garbage.

But is it profitable to heat the house with fuel briquettes? Aren't we spending significant extra money carrying these packages to the dacha? After all, buying firewood is also very simple, it is enough to worry about this issue, find out the phone number and responsive suppliers will bring as much firewood as we can pay.

We compare the real price of firewood and briquettes

Manufacturers state that the calorific value of fuel briquettes is 4.7 kW / kg. While this figure for dry wood is approximately 3.9 kW / kg. If we now substitute the price, we get:
- briquettes - 1.48 rubles / kW;
- dry firewood - 1.02 rubles / kW.

We overpay for the convenience of use, but on the other hand, I grabbed a clean package from the counter and carried it ... Next, we will consider the convenience of use as an experiment, and then draw subjective conclusions.
But before that, a bit of related information.

For comparison, the calorific value of the best anthracite of Donbass is 11.0 kW / kg, natural gas - 11.5 kg / kg. The price of such fuel is low.

The density of fuel briquettes is 950 kg / m 2, the density of firewood is 550 kg / m 3, and the bulk density of wood is 250 kg / m 3. There is one nuance associated with this density.

Firewood traders from uninformed buyers often demand a standard fee for a bulk cubic meter of chopped firewood (250 kg per cubic meter) - which is simply poured out in the yard, then measured. Firewood is actually sold at double the price. At the same time, for the same money, you can buy a cubic meter, but based on the price for the density of wood - 500 kg per cubic meter.

Is it convenient to heat with briquettes?

But what about the practice of use, what are the high end consumer qualities? The advertisement says that briquettes burn 4 times longer than firewood - it is indicated that firewood will burn in 30 minutes, while briquettes of the same weight - 120 minutes.

It remains only to carry out a comparative experiment on the combustion of fuel briquettes and firewood with a moisture content of 20%.

Wood briquettes have a moisture content of 8%, they consist of sawdust and chips very tightly compressed and held together by a natural polymer - lignin. Such a low moisture content and high density of the structure allows achieving an energy output of 4.7 kW / kg.

For example, with an increase in the moisture content of firewood, their heat transfer drops sharply. With a humidity of 50% (freshly cut wood), the calorific value of wood is already about 2.2 kW / kg. In order to lower the humidity to 15 - 25%, the logs must lie for a year in a rasp under a canopy.

Experiment

So, putting 4 large logs with a total mass of 2 kg of 20% moisture in the fireplace on paper and birch bark, we observe their combustion. They burn beautifully, give a strong feeling of warmth, it is impossible to stand next to 1 meter, the flame is high and bright. True, they burn out very quickly, finally, although not in half an hour, but in 60 minutes. During this time, according to statistics, firewood gave about 7.8 kW. And we spent 8 rubles for 2 kilograms.


Now we kindle the fuel briquettes. They also light up, but they burn sluggishly, without tongues of flame, the feeling of warmth is weak. But they obviously burn longer, and burn out, as stated in 2 hours. Probably, 9.4 kW was released, although stretching in time does not allow "catching" such energy. Spent - 14 rubles.

What else can you heat a solid fuel boiler, stove, fireplace

Now, for the sake of experiment, we carry out the heating of a solid fuel boiler after firewood and briquettes with the real highest quality anthracite. To break a piece of this coal with a hammer is a problem. The planes and edges are shiny, the corners are chipped and sharp, you can even cut yourself…. The density in a piece is about 1.5 tons per cubic meter, and the bulk density is about 1.0 t / m3.

We burn a couple of kilograms of firewood in the boiler - subjectively, the heat is "so-so", then we put only two kilograms of coal on top.

It flares up for a long time - about an hour, until the wood burns out. The flame is very low but very bright. A poker, dipped in heat, in a minute becomes not even red, but burning. The intensity of combustion directly depends on the supply of oxygen - it can burn out in an hour, or it can smolder for a dozen hours.

We give air to the maximum, coal burns out in about 2 hours. The heat is incomparably more - probably 22 kW (9500 kcal per kilogram) was actually produced, and the price for pleasure is about 18 rubles.

There remains crumbly white ash, but it is 2 times more than from firewood, and it is not suitable for the garden - you also need to organize transportation.

In general, interference in the comparative experiment of coal (anthracite), according to subjective assessments, takes it to the first place in terms of ease of use and price, if, of course, you need to intensively heat a country house.

But if you want to heat it quickly, light a fireplace, admire the flame, organize a barbecue - then you definitely need eco-friendly and inexpensive firewood.

Why then do we need fuel briquettes? - perhaps, when suddenly you need to sink a little, but there is no time, so much so that they forgot to stock up on coal and firewood.

Nevertheless, fuel briquettes are confidently occupying their niche in the fuel market, and are in constant demand for heating summer cottages and country houses. Whether it will be convenient and profitable to use them in specific conditions, it is possible to determine only by trial heating….

There is no perfect solid fuel. The use of wood, coal and various pressed waste has its pros and cons, including financial ones. The homeowner's job is to find the most profitable option. To clarify this issue, Vitaly Dashko carried out an experimental combustion of different types of fuel in real conditions. The goal is to compare which is better for heating a private house - fuel briquettes or firewood. We suggest that you familiarize yourself with the results and video of the process.

Why compare cheap firewood with expensive briquettes

For residents of regions rich in forests where woodworking enterprises are located, such a comparison is irrelevant. Firewood and sawdust in those parts are inexpensive or come for nothing. But we decided to compare them with briquettes for the following reasons:

1. There are practically no forests in the southern and desert regions. Hence the higher price of firewood bought by the owners of country houses and summer cottages.
2. In these areas, it is advantageous to press any kind of combustible mass - coal dust, agricultural waste and peat. Thanks to the development of such industries, the cost of briquettes is reduced and they become an alternative to firewood.
3. Heating with pressed products is more comfortable than with wood raw materials, which will be shown by our experiment.

The last reason is the conflicting reviews of homeowners about various fuels on thematic forums. A user who is not versed in this issue is unlikely to be able to navigate which types of briquettes are best used for a stove, fireplace or boiler. We will present the conclusions and expert opinion on this matter.

Conditions and course of the experiment

The object of verification is a one-storey private house with an area of ​​150 m² with an individual heating system from a solid fuel boiler. The walls are 300 mm thick, made of white sand-lime bricks, inside there is an air gap. There is no insulation of external fences, the windows are standard metal-plastic ones.

The rest of the experiment conditions look like this:

1. The heating system is closed, two-pipe. Divided into 2 branches - radiators and underfloor heating. The initial water temperature is 43 ° C.
2. The average daily ambient temperature is 4–5 ° С. The building is cold, warming up for the first time during the heating season.
3. The heat source is a solid fuel DIZ-24 (24 kW), equipped with a turbocharger and an automatic unit for maintaining the set temperature.
4. The scheme uses a small buffer tank (150 liters).

Note. Before the experiment, the boiler and coolant were warmed up to 43 ° C by burning small logs.

Task: load 3 types of fuel into the firebox one by one and check the duration of burning of each tab with a constant heating mode. The size of the load is the same -10 kg, the automation is set to maintain the water temperature at 50 ° C.

Target: determine what will burn out faster - firewood or briquettes, how significant the difference will be. The secondary goal is to compare the combustion of three fuels:

• dry shed firewood;
• round briquettes from sunflower husk;
• briquetted peat.

For reference. The wood species used is small elm (otherwise - birch bark), the stacking density of freshly cut logs with a moisture content of 50% is 600 kg / m³.

We deliberately did not burn "wooden" briquettes made from sawdust. The reasons are obvious: the products are much more expensive than peat and agricultural briquettes, their combustion properties have been repeatedly tested. If you are interested in this type of solid fuel, we recommend watching the video:

Approximate density of pressed husk is 1800 kg / m³, peat briquettes - 2200 kg / m³. These data are reference and do not play a large role in the experiment, since the fuel was put in the same amount - 10 kg. Let's start by burning wood.

The result of burning firewood

During the check, the logs were cut into 4 logs and loaded into the furnace, where a few hot coals remained. The controller started the fan and the wood burned for 1 minute. In total, laying 10 kg of wood was enough for 1.5 hours of boiler operation, after which the temperature of the coolant began to decrease.

Weight of each portion of fuel - 10 kg (with a bucket - 10.5 kg)

Points to note:

• dry wood produces little smoke and burns very evenly;
• the temperature jump after turning off the fan does not exceed 3 degrees (up to 53 ° C);
• small ash residue.

The process of burning dry wood is fairly predictable. If the entire chamber of the heat generator of this model (112 liters) is filled with such fuel, 1 tab will be enough for at least 8 hours. Raw (freshly cut) firewood decays faster: it gives off less heat and therefore is exposed to more blowing by a fan.

A typical picture when burning dry wood is a little smoke

Sunflower husk briquettes

Since the pressed husk contains a portion of vegetable oil, combustion differs in some peculiarities:

At the initial stage (on the left) there is a lot of smoke, then it is practically invisible (on the right)

For reference. The purge mode lasts 10 seconds and is activated at 5 minute intervals. The goal is to free the boiler chamber from smoke.

The burning time of a portion of agricultural briquettes was 2 hours 10 minutes, which is 40 minutes longer than firewood. Nuance: you need to learn how to use fuel correctly - at the initial stage, "sausages" emit a large amount of heat. By the way, in boilers with (without turbocharging) the effect of primary heating is less pronounced.

This is how the remnants of briquettes look at the afterburning stage, the boiler water temperature is 50 degrees

Combustion of pressed peat

In appearance, peat briquettes resemble, but differ in a square shape. The products are equally successful in getting your hands dirty, so it is better to load them with gloves. The characteristic moments of combustion are as follows:

• under the influence of pressurization, peat ignites well and gives a stable powerful flame;
• when the set temperature of the coolant reaches 50 ° C, the fan stops, the heating "jumps" to 53-54 ° C;
• peat briquettes smoke stronger than dry wood;
• the amount of the remaining ash is about 5-10%.

What kind of smoke from peat bricks could not be captured in the photo, because it got dark outside

Note. Peat contains some proportion of loam, which turns into ash. The amount of this share depends on the fuel manufacturer.

The duration of operation of a solid fuel boiler on peat briquettes is phenomenal - at least 3 hours, which is twice the burning of a similar amount of firewood. An unpleasant nuance is ash and black dust sticking to your hands.

The cheaper it is to heat your home

The price of fuel for heating a private house is of great importance, but it is meaningless to consider it in isolation from heat transfer. Let's calculate the cost of heating taking into account both parameters.

Combustion of peat fuel 3 hours after laying

In the area where our expert lives, they ask for the following price for proven types of fuel:

1. Freshly cut firewood - $ 20 e. for 1 m³. Let's tie the price to the weight: $ 20 for 600 kg or $ 33 e. for 1 ton.
2. Briquette of pressed sunflower husk - $ 57 per ton.
3. Peat briquette - 84 USD e. / 1 ​​t.

It is easy to calculate that 10 kg of wood will cost 33 cents, the rest of the fuel - 57 and 84 cents, respectively. Then 1 hour of heating on wooden logs costs 33 / 1.5 = 22 cents (remember, firewood burned out in an hour and a half).

Similarly, we will determine the hourly rate for burning briquettes:

• pressed husk: 57 / 2.17 (2 hours 10 minutes) = 26 cents;
• briquetted peat: 84/3 = 28 cents.

Burning of briquetted hulls of sunflower seeds

Interesting result, right? In our case, heating up an absolutely cold building costs $ 5.28. e. per day on wood, $ 6.24 - on pressed husk and $ 6.72. e. - on peat "bricks".

An important nuance. The prices of solid fuel in your region are probably different, and different heating equipment is installed in the boiler room. But the ratio and the principle of calculation remains unchanged. Apply this technique and calculate which is more profitable - firewood or briquettes in your particular case.

Note that we took the cost of raw wood (and it will decay sooner) and divided it by the time of full burning of a dry tree. That is, the difference between traditional fuel and briquettes is minimized. We offer to track the progress of the experiment on video and listen to an expert's opinion on this matter:

We do not persuade anyone to give up wood heating in favor of briquettes. The goal of the publication is to convey useful information, help homeowners save money and find comfort. What conclusions suggest themselves from the comparison results:

1. The attractiveness of firewood is a low price. The main thing is that they do not turn out to be too raw.
2. The previous section shows the cost of firewood delivered in the form of logs. The latter need to be cut into logs and split into logs. If the household does not have a chain saw, you will have to pay extra for sawing.
3. Due to their low density, logs take up more space than briquettes.
4. Pressed waste burns much longer than wood and gives off more heat. The number of visits to the boiler room will decrease.

It is better to heat homemade stoves with wood or put a small amount of briquettes

An important nuance. High-calorie fuel briquettes pose a hazard to. When the firebox is fully loaded and the chimney is open, the steel body of the stove is often deformed by the high combustion temperature.

Pressed products are not flawless. Fuel from agro-industrial waste contains vegetable oil that settles on the walls of the chimney in the form of soot, while peat leaves ash. To find the best solution and clearly select briquettes for the stove, boiler or fireplace, set aside a part of the day off and conduct a similar experiment with a variety of fuels. Combine "bricks" with wood, watch the results and count money - this is the sure way to economical heating.
