Design and types of
The most important distinguishing feature of this type of furnace is heat transfer, reaching 3.5 kW, while it can be melted only once a day. Therefore, we can say about its high profitability. High heat transfer efficiency is achieved due to the presence of a closed furnace where heat accumulation takes place in the direct chimney and the heating effect is transferred to the furnace walls, thus the useful action of the furnace is 75%.In order to fully utilize the heat, a coil is built into the Swede in which water is heated.
The oven is designed for heating a standard small house up to 100 square meters.m. When choosing the location of the oven, it should be noted that a small room will not work, because there will not be enough air for combustion. Suitable room is not less than 16 squares.
You can place the oven on the wall( wall), in the corner of the room( angular), in the center( island), mount it in a wall( built-in), hang it to the ceiling( suspended).Most often prefer a wall-mounted version. In this case, it is necessary to take into account that the wall was completely fireproof, there were no communications, no postings. As a rule, when planning to build, the main part is located in the kitchen, and the coarse( rear part) went into the next room. If the stove is laid after the construction of the house, then it should be located near the main chimney, but it will be right to plan the Swede already at the design stage of the house so that the chimney is located in a supporting wall laid out of non-combustible materials. Do not place the oven near windows or doors, otherwise drafts will interfere with normal draft.
How Swede works
The oven is based on an oven and a water heater. For cooking, a cooking iron surface is provided, which also largely transfers heat to the room. Use Swedish can be in winter and summer for cooking and heating water, but the flue gases will go into the chimney, not heating the room, and in winter the gases are retained in the heating channels, they heat up and then are removed.
Scheme of operation of the
- furnace The fuel burns in the furnace, and the resulting gas passes under the cooking plate.
- The plate, oven is heated.
- the heating gases accumulate in the enclosed space of the heating chamber where it is heated.
- The gases are removed through the chimney flue.
What do you need to build a Swedish stove with your own hands?
Before construction, create a drawing, a sketch of the future structure and calculate the number of necessary materials. It will be required:
- 230-255 pieces of red refractory bricks;
- 250 kg of good clay;
- 250 kg of fine sand;
- steel corner 45x45x3 mm;
- steel strips 40x3 mm;
- heating doors 270x300 mm;
- doors for ash-bath;
- cooker made of cast iron with burners;Gate valve;
- ;
- drying box( oven) made of steel;
- hot-water steel box
Constructing the
furnace Preliminary preparation of the foundation of concrete, which must be kept for a month. In a month you can start laying.
1-2 rows - solid bricks.
3-5 rows - zonal camera, the door is mounted on the ash pan.
5 row - overlapping on the corners. In this place we provide the location of the drying chamber with dimensions corresponding to the dimensions of the box.
From the 6th row we are building up the combustion chamber inwards so that we can lay the grate and the door of the furnace.
8-9 series - furnace. At this stage it is necessary to lay the oven box.
11 series - on top of the box are laid out the strip of steel, covered with a layer of mortar, providing for the location of the chimney.
12 row - a place is prepared for the hob.
13 series - the cooker itself and the hot water tank.
14 row - the base of the chimney.
Probably, you still have questions on the stages of work, since in one article you can not fit everything at all desire. Therefore, specially for you, we have prepared photo and video instructions. With a clear step-by-step compliance with the recommendations, you will certainly get a great oven that will warm your home for many years.
