Ease of use
Storage
Solid fuel must be stored in a designated place with certain conditions:
Pellets - put in plastic bags to protect from moisture; store in a dry place if the granules have high porosity.
Firewood - close from rain and snow; ventilate so that dampness does not accumulate; make the base of the boards so that mold does not appear.
Coal - store under a canopy at 20 ° C and below so that it does not oxidize; protect with covering material so as not to ignite spontaneously.
The gas tank is filled a couple of times a year, then the gas itself runs through the pipes. The reservoir is buried underground and does not take up space on the site.
Fuel loading
Firewood and coal need to be loaded constantly. Therefore, often these works are performed by stokers of our time - guests of the capital.
Fuel pellets do not require constant loading, the normal mode is once a week. But still, the pellets themselves do not jump into the boiler yet. There is an automated boiler - "carborobot". You can take a look at him.
The gas tank is filled every six months, most often in the fall. Each stage is strictly regulated, you only need to open the gate. The gas carrier will pass on any road, the tank will be filled in 1-2 hours. You can also save on refills.
Note: TT is solid fuel.
Waste and cleaning
A firebox with coal and firewood is smoke, fumes, soot, soot, tar, ash, ashes. That is, operations to clean the equipment once every 2 weeks.
Wood ash dumps can be used as fertilizer in the garden, fill the pits on the primer with coal ash. Or call a utilizer - a regular expense item will be added.
Specialists inspect the gas tank 2 times a year: in spring and autumn. If necessary, carry out cosmetic repairs.
Technical inspections of the gas tank
After installation, you conclude a contract for 1 year of free service. The service includes 2 preventive engineer visits in autumn and spring and 1 emergency call within 24 hours.
Then the agreement can be renegotiated for 12,000 rubles a year. Or use the one-time inspection service for 3,500 rubles. An unscheduled emergency exit costs 5,000 rubles.
Efficiency
Efficiency of pellets, coal and firewood
How many centuries they warmed themselves with wood and coal - they did not complain about the cold. Need to heat two floors, not a hut? 1 kg of peat pellet burns like 1.6 kg of wood. True, with a large house there will still be difficulties.
Do you know why? Just one word: stoker. This is a person who will throw fuel into the furnace for you around the clock. No stoker. You left for work - the oven cools down. They went to bed - in the morning the house was cold.
The efficiency of heating on wood, coal and even pellets is sharply reduced if we calculate the labor costs for loading fuel. And also waste. Coal provides ash dumps, which will have to spend a legal day off.
When burning 1 kg of solid fuel, 5 kW of thermal energy is released. For a 100 sq. m need 10 kW per hour, that is, 2 kg of pellets or coal every 60 minutes. Someone has to put this fuel in, albeit not so often.
Heating with wood and its analogues is very vain: find, order, download, follow, clean, take out waste. But everything is according to the classics + charging and discipline.
An effective system can be set up: choose a carbobot or an auto-feed pellet boiler, schedule a fuel loading schedule. It will take money, free time and self-organization.
Fork efficiency of a solid fuel boiler - 50-90%. The spread of efficiency depends on the heat loss of the house, the calorie content of the fuel and other factors. This is a very low efficiency compared to electric boilers and equipment using natural or liquid gas.
Calculate yourself
When burning 1 kg of solid fuel, we get 5 kW of thermal energy. When burning 1 kg of liquefied gas, we get 12.8 kW.
LPG efficiency
The efficiency of the gas boiler gives a stable 97%.The supply of gas from the tank is smooth and fully automated. A house on gas heating does not depend on network fluctuations, pipeline failures and fuel supplies, as is the case with firewood.
There is nothing to cover: autonomous gas is more efficient in all respects. Other things being equal, it gives 2.5 times more thermal energy. Therefore, the gas tank will be more expensive than the good old firewood and coal, right? Let's count.
Qualities of suitable firewood
First you need to decide which qualities are positive, which are intolerant, and which are unimportant.
Sparks and crack
When logs crackle in a fire, this means that the wood bursts under the heat and a small ember can fly off.
Sparks are very small embers carried away by smoke.
Both can cause a fire.
Of course, when burning firewood in a pyrolysis barrel (a closed container with a low air supply to the firewood), this is not important. But in nature or in the country, where there can be easily flammable objects, such qualities of firewood must be taken into account
Hardwood wood cracks and sparks least of all, coniferous wood more.
Heat
The temperature and burning time of coal from different types of wood is not the same. Hard coals burn longer and hotter. Champion here oak. Its coal burns longer and hotter.
Resinousness
Many are convinced that everything in charcoal has already burned out and it is pure carbon. But it is not. Coal, like a sponge, absorbs the substances of burning firewood and then gives them to the barbecue. The resins will give the meat a bitter taste. It doesn't suit us.
Resins are found in all conifers. And we can say for sure that you don’t need to fry shish kebab on pine wood (on the coals from them).
Aroma
Barbecue on live coals is valued for the light smell of smoke. The most “delicious” smoke is from alders and fruit trees (pear, apple, cherry). Of course, the effect is much weaker than using wood chips in the grill, but connoisseurs say that the difference is felt.
Rowan, poplar, acacia and elm are also not suitable. This firewood gives a "heavy" smoke.
For different dishes your coal
The flavor of the smoke and the dish should fit together.
Cherry - for hamburgers, lamb and poultry (most of all for duck).
Alder - for salmon / trout, turkey and chicken.
Apple tree - for game, pork, chicken and seafood.
Oak is for meat.
Maple wood - for pork, seafood and chicken.
Birch - for chicken and any meat.
Impurities - no
If we didn’t like natural resins, then impregnated construction wood, scraps and old furniture will not work either. Synthetic resins, adhesives and plastics contaminate coals. As a result, the taste is nasty and full of harmful chemicals on the meat.
Humidity
What is bad moisture logs?
Firewood burns longer (and unevenly) and during this time the coals that we need for barbecues partially burn out. Little or very little comes out. Choose dry.
The size
When burning a tree on coal, it will be most rational to stack the firewood more densely. So the output will increase.
Conclusion: size is important and you need to focus on your hearth, barbecue or barrel. Even for a fire, you need to cut the dead wood into pieces of a suitable size.
More coal
Artisanal or professional charcoal burners use special ovens (pyrolysis).
You can estimate the yield of coal from wood of different species as follows:
If a pyrolysis oven is not used, then the coal yield is very different from the table.
Firewood that burns quickly and hot produces less charcoal than evenly burning wood.
The former include birch and aspen, and the latter - hard varieties and fruit trees. Alder is somewhere in the middle.
Harvesting coal is a long process and it is better to do it in advance. You can combine burning firewood and cooking barbecue on the grill with a firebox. Or use ready.
Price
The cost of heating a house with pellets per 100 sq. m
A ton of standard pellets costs an average of 8-9 thousand rubles. Let's take the price of 8,500 per ton. With a heating season lasting 8 months, we get:
heat loss - 28 224 kW / h;
pellet consumption - 5 tons 644 kg;
in money - 47,980 rubles per season.
Calculate yourself
Prices for pellets in the Moscow region - 8.50 rubles per kg. The average winter price of 1 liter of liquefied gas is 21 rubles.
A ton of coal or fuel briquettes costs about the same as a ton of pellets. Firewood is a little cheaper. Additionally, take into account the associated costs after installing the boiler:
Fuel delivery: from 7,000 rubles.
Waste disposal: from 5,000 rubles.
Stoker payment: from 10,000 rubles (without accommodation).
Heating with a gas tank: cost per month and season
Heating with liquid gas at home 100 sq. m costs 4-5 thousand rubles a month when buying gas at a high winter price (21 rubles / l). During the heating season (8 months) 40 thousand rubles are paid. It turns out even cheaper than pellets with full automation and no waste.
Tip: choose a heating system according to the characteristics of the region. Somewhere there is forest and cheap firewood, somewhere with coal it is easier and more profitable. An autonomous gas tank is not tied to a place: LPG costs the same everywhere.
The cost of installing a gas tank and a solid fuel boiler
We made an average calculation for the same house with an area of 100 sq. m. The final price includes operating equipment and heating throughout the year.
They did not include the purchase of a boiler in the cost of autonomous gasification. The range of offers is too large: from 37 to 100 thousand rubles.
Equipment: Real-Invest gas tank with high nozzles for 4,600 liters.
Works: installation, sand delivery, digging with an excavator, soil removal (2 cars).
230 000 rubles
Equipment: long burning solid fuel boiler Buderus Logano 124 201.
Works: installation of the boiler 12,000, additional installation up to 10,000.
146 201 rubles
Refueling for a year
A full tank (enough for 12 months) multiplied by the cost of gas:
3,910 l x 21 rubles/l = 82,110 rubles
Multiply the cost of fuel per month by 12:
6,000 rubles x 12 = 72,000 rubles
1 500 rubles
Included in installation
Boiler conversion to LPG
12,000 rubles + a set of nozzles (depending on the model of the boiler, from 2 to 8-9 thousand rubles)
Delivery (in the Moscow region)
1,000-3,000 rubles
335,000 rubles. Gas is automatically supplied to the system
221 201 rubles. It is necessary to throw pellets into the system once a week
The better to heat the stove with coal or wood
In the Moscow region, many different types of solid fuels are sold, which are used in furnaces. Starting from popular ones: firewood, pellets, briquettes and coal, and ending with rare ones: dung and peat briquettes. At the moment, according to independent studies, the most popular types of fuel are coal and firewood. Moreover, both wood and coal have their own advantages and disadvantages, which should be taken into account when choosing and buying fuel.
Coal is a mineral, a type of fuel formed from parts of ancient plants underground without oxygen. The international name for carbon comes from lat. carbō ("coal"). Coal was the first fossil fuel used by man. He enabled the industrial revolution, which in turn helped develop the coal industry by providing it with more modern technology.
On average, burning one kilogram of coal results in the release of 2.93 kg of CO2 and allows you to get 23-27 MJ (6.4-7.5 kWh) of energy or, at an efficiency of 30%, 2.0 kWh of electricity . Hard coal can be of different grades - brown, black and the best - anthracite. The latter releases more heat during combustion and less is required to reach the required temperature.
Firewood - pieces of wood - timber - intended for burning in a stove, fireplace, firebox or fire to produce heat and light. In accordance with the requirements of GOST 3243-88, the quality of firewood in Russia is standardized by wood species, nominal length and accounting gradation, by the area of heartwood rot (as a percentage of the end area), by the amount of firewood in a batch with rot from 30 to 65% of the end area, and the height of the remnants of branches.
So after all, let's return to the question that worries us, which is better, firewood or coal for heating?
Coal is well suited for combustion in heating system boilers installed in separate rooms, in outbuildings or in a separate boiler room. It is not recommended to use it in ovens installed in residential premises.Since coal burns for a long time and practically does not burn out in the furnace to the end, and therefore it is impossible to close the chimney, you always have to leave it a little ajar so as not to burn yourself with carbon monoxide. At the same time, dry firewood burns quickly and provides enough heat to warm up the stove. Firewood burns to the end, and you can safely close the valve on pipe and thereby slow down the cooling of the furnace and the loss of heat through the chimney.
It is very difficult to kindle coal without logs or special ignitions. Therefore, even those who heat stoves with coal still buy firewood to light coal. Oak firewood is the best in terms of heat transfer, but they are expensive, so birch firewood is optimal in terms of price / heat transfer.
People who burn coal are well aware that coal dust is harmful to the human body. And when throwing another batch of coal into the furnace, it is rarely possible to “not raise dust” and not to stain everything around with coal dust. Firewood, mostly without dirt and third-party impurities.
Wood heating compared to coal is the most environmentally friendly. Since the combustion of wood releases a minimum amount of carbon dioxide, and it cannot cause much harm to the biosphere, compared to coal.
Therefore, when choosing between charcoal and firewood, we strongly advise you to opt for firewood. It is safer for health and more profitable from the point of view of maintaining cleanliness in the house.
Reliability
A solid fuel boiler works stably under 2 conditions: there is a supply of fuel and the one who fills it up. Like a classic stove, you can rely on such a boiler. You just need to monitor his condition.
Tip: one of the undoubted advantages of solid fuel boilers is the ability to heat anything when there are no pellets and coal. On wood chips, a Maxim magazine binder, and the wall of an old barn, you can wait for fuel to be delivered.
Autonomous gas tank is exceptionally reliable. It continuously evaporates gas even at frosts under 40 degrees. The human factor in the case of liquid gas is excluded. With proper installation and operation, there can be no interruptions.
Results
Installing a gas tank is more expensive than installing a solid fuel boiler: 300 thousand versus 200. Liquid fuel itself is also more expensive than pellets, coal, and even more so firewood.
However, it is much more profitable to heat LPG in terms of costs during the heating season. Liquefied gas is 2.5 times more efficient.
The gas tank creates an autonomous heating system without human intervention. The main problem with solid fuels is that they need to be dealt with regularly. The tank is more modern and safer.
Unobvious bonus of autonomous gasification
The gas holder can feed the electric generator itself and maintain an autonomous power supply. The pellet boiler is dependent on electricity - when the network is turned off, it will go into standby mode.
Running away from the bustle of the city, people are trying to buy or build a house away from civilization. But they are faced with the fact that often the main gas pipeline is not connected to such remote places and it is necessary to look for ways that will ensure warm and comfortable living in a country house. There are many options for heating a country house, but in this article we will answer the most important question that interests everyone, without exception, is it cheaper to heat a house?
The following are the most popular types of fuel:
- Firewood is normal.
- Coal.
- Eurowood.
- Electricity.
- Liquefied gas, in cylinders.
- Diesel fuel.
What kind of fuel will be appropriate in a particular building depends on the operating conditions of this building, the price of fuel and ease of use.
Fuel selection conditions:
- Fuel price.
- The price of the heating system and its installation.
- The cost of maintenance of the heating system.
- The air temperature of the cold season in this region.
- Availability of communications.
- Possibility of fuel delivery.
- Purpose of the building: this is a place of permanent residence or a place of temporary residence for recreation or work.
- The presence of heat loss and the degree of thermal insulation.
- Ease of operation of the heating and fuel system.
- Availability of a certain type of fuel in a given region.
For the correct choice of the most efficient type of fuel, it is necessary to carry out an appropriate calculation, which will take into account the efficiency of a given heat source, heat loss, area and volume of the heated room.
All units of measurement must be reduced to a common denominator. It is most correct to use kilograms.
