Oven swede diy

Known modification of domestic ovens called "Swede" can be used for heating country houses, and for cooking. Differing in relatively small size, this class of furnaces have a number of advantages, among which are:

• quite high efficiency;
• excellent heat dissipation;
• relatively small size.

It has been practically confirmed that with a small occupied area such furnaces are able to effectively heat household premises with an area of ​​up to 40 m ?.

To obtain a higher heat transfer furnace, you need to increase its size.

Before you manufacture the stove, you must be completely sure that you can cope with this task. In the event that there is no such confidence, we advise you to invite an experienced stove-house counselor as an assistant. In this article we will look at how to do a swede oven with your own hands.

Materials used in the manufacture of the furnace

For the manufacture of ovens of small sizes, you may need the following materials:

• Clay;
• Red and chamotte brick;
• Doors of various types (blowing, furnace, auditing);
• Gate valves;
• Cooking cast iron stove;
• Grate;
• Steel corners and stripes;
• Mertel.

Preparatory stage

To successfully carry out the masonry work, you should first examine the scheme in which the order of arrangement of the rows of bricks (the so-called ordering scheme) is indicated.

After that, you will need to organize a test laying of bricks (without mortar) in compliance with the ordering scheme used. Such an operation will allow you to avoid any errors possible during the final installation of the Swede oven. In addition, thanks to this, you will be able to determine the required number of “incomplete” bricks (halves or smaller parts).

As a mortar used for laying the oven, only special clay mixture is used.

For its preparation, you will need to sift the clay selected for the job and fill it with clean water. In addition, well-sifted sand in an amount equal to the volume of clay should be added to this solution.

Immediately after this, water is poured into the mixture in an amount equal to a quarter of the volume of the mixed clay. The resulting mass is thoroughly mixed to a consistency, resembling in appearance very thick cream. Before starting laying bricks, waterproofing is laid on the previously prepared foundation, which can be used as a normal roofing felt.

Useful tips

Before starting the masonry work we advise you to familiarize yourself with the following recommendations of specialists:

1. Bricks before laying must be wetted in water, which excludes the possibility of their absorption of moisture contained in the clay.
2. Laying bricks on the bed is made by pushing it into the mortar, the excess of which is then removed using a trowel. In the process of laying all the time should control the thickness of the seam, which should not be more than 5 mm.
3. It is best to carry the furnace door onto the end wall of the structure, which will considerably facilitate the laying of the logs into the combustion zone.
4. For reliable fixation of the door, installed in the course of laying brick, the latter are reinforced with wire, the free end of which is embedded then directly into the brickwork.

Masonry furnace

The classical scheme of the stove styling looks like this:

1. The first two rows are laid on the base plane with exact repetition of its configuration.
2. Starting from the third row, space is provided for the chamber, as well as a blower and inspection doors.
3. The fourth molded row must completely repeat the third, after which the cast-iron door is used, which is used to clean the furnace from the combustion products (ash).
4. Then you can go to the tab of the so-called combustion chamber, laid out partly from fireclay (refractory bricks). At the same time, a gas exhaust duct is formed that is offset to the rear wall.
5. After that, according to the above scheme, the overlap is made between the back wall of the wind chamber and the gas exhaust channel.

All subsequent operations should be carried out in full accordance with the above ordering scheme (of course, taking into account the characteristics of the premises you are building). It should not be forgotten that all cast-iron and metal elements embedded directly into the masonry should be securely fixed in it using steel wire (previously well annealed).

At the final stage of manufacturing the stove, the upper flue gas ducts are completely blocked (except for the chimney hole) and due to the expansion of the masonry, a small protrusion of about 5 cm is formed.
