The fireplace, high-performance-commonly called Russian stove - is a cheap and easy fixture building. One of its key strengths is the ability to store heat in its structure to deliver it slowly over hours even after powered off. If you compare this model with a common range iron, the Russian stove produces the same heat with 100 kg of firewood that a 400 kg iron.
These stoves largely solve the problem of heating all winter so. in these pages, try to explain its operation and construction that anyone with minimal skills, can build and enjoy its benefits.
do we return
A certain percentage of return for the use of wood, say 30%, meaning that every 100 pounds of fuel we burn only 30 kilos remaining heat inside the house. The rest is wasted because there is a poor combustion of fuel and because much of the heat is lost up the chimney.
For example, let the performance of some types of stove.
open hearth fireplaces or stoves.
A large open fire is very romantic but, in the words of John Seymour, "All it does is to comfort the heart, cool and warm away the sky,"
A common stack acts like a powerful extractor air. The room in which it is installed causes the air renewal is five to six times per hour, when what is needed is that the replacement of stale air for fresh air at just one air change per hour (for the room has no musty smell). This excess fresh air forcibly penetrates through the cracks of doors, windows and tin roofs, causing the familiar "whistle" that have major negative effect on the comfort of home.
yields of these homes open fire hardly exceed 10 to 15%. more. if we take into account 24 hours a day often becomes more the cold that comes down the chimney at night when the fire goes out, that the heat while it is on delivery, so the overall performance is negative.
may seem surprising, it is common throughout the winter is a stove that "cool."
yields of around fifteen percent in these homes means that if you bring a truckload of dry soft wood (about 6,000 kg). What remains of that heat inside the house is what could have brought in a truck (900 kg). The other 5,100 have gone up the chimney. If you're proud of how well our fireplace strip is possible that the loss is greater.
Then remember that seven or eight trees that you turn, cuts, tears, piles, logs and then burn, only uses one as heat for your home and comfort. Unquestionably a major waste of fuel and labor.
iron stoves
Salamanders
common iron stoves have an efficiency that ranges in 20%. and require very fine wood billet. Here something improves achievement. Some salamanders evolved design iron or improved yields can reach 40%. but its cost is quite high.
Nordic There are some iron stoves reach yields of 60%.
Kitchens economic
We have not found efficiency values \u200b\u200bof these devices but, by design and circulation of smoke, estimated to reach 30%. Without doubt, for cooking and heating the kitchen is very appropriate, but to heat a house usually does not have the right location. They also require a great job of chipping wood,
These stoves are ideal for specific heat area homes.
Stove High Performance
High Performance stoves, Russian stoves commonly called, are artifacts of heating, built of refractory bricks, which are characterized by having excellent overall performance and other qualities of interest
Different tests have been conducted in several research institutes abroad, cast yields between 84 and 93%, far exceeding any of the other stoves named.
If we compare, for example, a common iron stove, these yields mean that the Russian stove we produce the same heat with 100 kg of fuel that a 400 kg iron
