How to choose the oven?

The oven heating is currently used by more than 30% of the population. And its share, especially with wood, in an uncertain DH is unlikely to be reduced, considering also further increase the price of electricity and heat and fuel (gas, coal, refined petroleum products).

In the countryside cottages, houses are usually heated stoves, it is a universal structure: they also cook food, bake bread, dried grain, even wash is in the bath, and finally, her sleep. As a rule, near the stove is constructed in one volume of the so-called Dutch oven, podtopok with plates in a niche for cooking. Widely used heating stoves square and round shapes in metal case made of smooth and corrugated roofing iron and finished with tiles or plaster.

Heating stoves are divided into two groups: neteploemkie and heat. The first group includes metal furnaces used for temporary heating. Called the heat capacity of the furnace in which the active volume of accumulating heat, more than 0.2 m3. Such furnaces, depending on the length of their cooling furnace divided into a large heat capacity (for a period of cooling to 12 hours), medium (up to 8 hours) and short (3-4 hours).

Find an application of so-called high-oven warm, usually prefabricated. To reduce the non-uniformity of temperature in the room, you can use the oven long and continuous mostly of foreign origin. On the basis of such furnaces may further joint engineering hot water heating systems and hot water.

Furnaces are also divided on the scheme of movement of flue gases.

How to choose a stove? The answer to this question depends on the lifestyle of the family, the mode of operation of the house. For example, in the year-round home, the presence of animals appropriate to the massive combined heating and cooking stove. On incidental heat your home when you need a short time to reach the desired temperature, correct use of the oven at the massiveness. In this case, the room temperature is dependent on the number of burners in the furnace day.

The main provisions of the design stove heating in buildings for different purposes given in SNIP 2.04.05-91 *, in reference and educational literature on heating, so you can stay only on certain matters which have given a place of retreat from the regulatory requirements .

Applications stove heating is limited. Allowed furnace, for example, in residential and office buildings with a number of not more than 2 floors (not counting the basement) in public single storey buildings with a limited number of places and in the premises of categories D and E is not an area of ​​over 500 m2.
maximum surface temperature (other than cast flooring, doors and other furnace equipment) is received, depending on the purpose of premises, but in any case should not exceed 120 & deg; C in the furnace area, equal to not more than 5% of its surface area ( with prolonged stay of people).
For a correct determination of the heat capacity and the type of furnace you need to know the amount of the estimated cost of heat in the room when the outdoor temperature, the corresponding provision of the coldest five days 0.92 (if you live in a room in the winter), and the type of fuel intended. The amount of solid furnace must provide the specified thermal conditions. In batch furnace oven (once or twice a day) fluctuation of the room temperature should not exceed & plusmn; 3 & deg; C.
To ensure traction chimney height from the grate to the mouth should be at least 5 m. To the chimney is not overturned in the wind, its mouth should be placed above the roof: at least 500 mm - over the flat roof; not less than 500 mm - over the ridge of the roof or parapet at the location of the pipe is 1.5 m from the ridge or the parapet; not lower ridge or parapet - when placing the tube in the region of 1.5 to 3 m from the ridge or parapet; not below a line drawn down from the ridge angle 10 & deg; to the horizon - at the location of the chimney from the ridge at a distance of more than 3 m. When passing through the furnace roof is necessary to provide an otter on the roof.
allowed a heating oven to three rooms located on one floor.
The design and dimensions of the firebox must correspond to the type and amount of fuel burned. In thermal power 3000 W recommended firebox inside lined with refractory or refractory bricks. When burning wood is impractical to do with deaf hearth firebox without grate and ash since The efficiency of the firebox - about 35%. For the combustion of coal, anthracite firebox grate equipped with an enlarged open area. For the combustion of moist peat used polushahtny firebox with inclined and horizontal bars and three doors.
