The well-known modification of domestic stoves called "Swede" can be used both for heating country houses and for cooking. Differing in relatively small size, furnaces of this class have a number of advantages, among which are:
It has been practically confirmed that with a small occupied area such furnaces are able to effectively heat household rooms with an area of up to 40 m².
To obtain a higher heat output from the furnace, increase its size.
Before you make a 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.
Material for the furnace
For the manufacture furnaces of small sizes you may need the following materials:
For the success of the masonry works you should first examine the scheme, which indicates the order of the rows of bricks (the so-called ordering scheme).
After that, it will be necessary 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 Swedish furnace. In addition, thanks to this, you can determine the required number of "incomplete" bricks (halves or smaller parts).
As the mortar used in laying the kiln, only special clay mixture is used.
To make it, 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 thereafter, 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 that resembles very thick sour cream in appearance. Before starting laying bricks, waterproofing is laid on the previously prepared foundation, which can be used as a normal roofing felt.

Before starting the masonry work We advise you to familiarize yourself with the following recommendations of specialists:
The classical scheme for a consistent stowage of the furnace looks like this:
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 ducts are completely blocked (except for the chimney hole) and due to the expansion of the masonry, a small ledge of about 5 cm is formed.
