Human control of fire might have a place for the first time, almost half a million years ago. There is limited evidence that firing clay, simmered dishes, and the ancient of charcoal, which seem to have more than 400 000 years, increasing the mastery of fire in the hands of our ancient ancestor of the Pleistocene, Homo Erectusa . Scientists have not found enough evidence to fight against the fire, came from so far to reach consensus, but most scholars agree that at least from 125 000 to 150 000 years ago, the first people have mastered the art of shooting, control and use of fire.
Thanks to the development of the fire had a chance for quick development of cognitive abilities ; the human brain is responsible for at least one-fifth of all calories consumed by the body. Food is easier to digest due to the cooking process – not to mention the greater variety of products, which are safely edible easier thanks located kaloriom cooking, making brain function more efficient and dynamic. The fire provided early humans with additional protection, because it might serve to repel animals, provided illumination in the dark, and, of course, allowed and warm.
Wherever people have settled, found ways to challenge fire management . This is true regardless of climate or flora and fauna of the environment. Despite the standard of plenty of heat, inhabitants of tropical areas use fire for cooking, safety and firing clay. In cold climates of the Arctic, even where there is little wood available, people found ways of fire making using animal fat as a fuel source.
Modern man should not worry that benefits from fire in terms of the evolutionary development of the brain, but everyone in the world needs to worry about a certain range of temperatures, to ensure a safe and comfortable lifestyle. If you live in an area susceptible to low temperatures, and you are looking for an inexpensive, efficient way to heat the house, think about using old technology of mankind, a fire in one of the most effective formats: kiln operating on wood pellets .
Why does the Pellet stove work so well
After downloading the relevant fuel (high quality pellets), a great pellet stove can achieve a productivity rate of 90 percent. This means that 90 percent of the fuel that is burning, is converted into thermal energy, which will be used to heat the home. Compare this with an annual fuel efficiency (AFUE, as it usually defines the Ministry of Energy and other specialists – and you will appreciate this figure: some furnaces, heated by oil or gas, I can only offer 10% AFUE and a lot of old systems are actually more miserable performance by 50%.
Stoves, wood pellets are becoming regular and reliable heating properties, constantly supplying fuel from the hopper to the combustion chamber . Unlike the warmer and cooler cycles that you experience in traditional wood, which requires a periodic download of the wood, and then spike, and then reduce the heat, stoves, fuel pellets delivers consistent performance as long as hopped full.
And because the pellet stove use wood, compressed of segments and / or sawdust, or use biomasowe recovered fuel derived from such materials as food waste , furnace peletowe are not only very effective, but are also a source of much more environmentally friendly source of heat than wood.
Choosing a furnace, running on wood pellets
There are two main categories of stoves for pellets and probably only one of them will work in Your place of residence (or location of Your activities). The first category includes stoves, fuel pellets, which are designed for integration with Central heating system ; these furnaces are rarely aesthetic, but a more efficient and cheaper to maintain after the first purchase and installation costs.
The second type of furnace, operating on wood pellets often less will look like a traditional wood burning stove and is designed for placement in a conspicuous place in the room. As warm as a flickering flame in this category kiln operating on wood pellets will enjoy all the room. Both types of furnaces for pellets, typically require connection to a standard AC outlet and will not operate without electricity, supplied through a wall outlet or a spare battery (big battery) or a generator. Keep this in mind when you consider that stove on pellets, if frequent interruptions in the supply of electricity; don’t want to stay in the cold without a backup plan for when the electricity fails.
When it comes to choosing a furnace, if you need a machine that will be associated with Central system of ventilation and air conditioning have to buy more based on statistics – i.e., the capacity required for the earth’s surface estate than any other factor. Assuming that you are looking for furnace fuel pellets that will sit in the room, you can also shop based on the heat output. Many furnaces for wood pellets could easily heat up to 1500 square feet of surface, and can be used as the sole source of heat for homes of this size or less. (Note that these ovens may not work so well in homes with multiple floors or located in certain floor plans).
Also, remember to take into account the time of burning potential of your furnace. Many furnaces running on wood pellets offers hours and hours of continuous heating, and some of them burn for almost 24 hours without re-filling peletami. If you live in a place that in winter is very cold, the longer the recording session, the better.
