First you need to decide on a specific type of oven. And for this, study in detail the existing types of furnaces and choose the most suitable option for yourself:
These ovens operate in slow burning mode.
If this is your first time building a stove, then for independent construction, choose a Dutch stove or a melting brick stove, because the construction of Swedish stoves is more difficult and requires some experience in this matter. As for the Russian stove, you should not undertake its construction yourself.
The next step is to determine what size your stove will be and how many rooms it will heat.
In a small house, the stove can be placed in the wall between rooms.
The basic condition for the placement and construction of the stove is very simple: direct heating from the walls of the stove must cover a large number of rooms.
If this is not possible, it is better to use ovens with built-in hot water coils. With this version of the stove, the remaining rooms will be heated with special heating radiators.
For an increased service life and proper operation of the stove, it is necessary to carefully approach the choice of building materials, namely bricks.
In addition to strength and durability, the choice of brick also affects its thermophysical properties, which provide heat in your home.
For a Swedish stove, it is very important to choose high-quality building materials, but for a Dutch stove, the quality requirements are not so high.
Heating brick stoves used to be made of red brick, but today there are 2 main types:
Below we give some recommendations for the purchase of material for the construction of heating brick ovens:
After choosing a heating furnace, a high-quality foundation is required ... Small Dutch ovens and heating and cooking stoves will be considered an exception; they do not put a lot of stress on the sub floor.
For all other cases, the heating brick oven should stand on a foundation, and preferably on a reinforced concrete monolithic one.
Its dimensions are made 5 cm larger than the dimensions of the furnace, and the thickness of the slab should be at least 150 mm. The foundation must be built separately.
The foundation for the furnace must stand at least 3 weeks, only after that a waterproofing layer is laid, then asbestos sheets for high-quality thermal insulation. Next comes a sheet of steel and a felt lining, from which the laying of the oven begins. The lining must be wetted, and after laying, let it stick to the metal.
And only after that you can safely proceed to the construction of the walls of the furnace.
Where to start laying?
To understand this issue there are special building diagrams that detail each row of brickwork, from the base to the chimney. After you have decided on the choice of a furnace and purchased everything you need for its construction, then in the received project documentation you can find a detailed image of the brick furnace scheme.
Before starting the brickwork of the stove, it is necessary to prepare a solution of white clay and quartz sand in a ratio of 1: 1. You should not use hard water with a large amount of salts and magnesium.
Before preparing the solution, the clay is soaked and left in water for 24 hours, then passed through a special sieve. Then add sand and mix the solution. In its consistency, the solution resembles thick sour cream.
Now let's consider in more detail the masonry itself. All sides of masonry bricks have their own names, and they determine the type of masonry.
The most common masonry of brick ovens is bonder and spoon. That is, from the front side of the brick wall, we can only see these two sides of the brick. There is also bedding, but it is extremely rare to find it, since it is not used for brickwork of stoves. When laying, the vertical joints between the bricks must not line up.
The brickwork of the stoves starts from the first row, constantly checking according to the scheme where the masonry is located.
In this work, haste will be a bad helper, the main thing is quality.If you are new to construction, it is better to initially lay each row without mortar, referring to the drawings. And only after making sure that the entire installation is correct, apply mortar to the bricks and lay them completely.
The seam thickness should be at least 2 mm, but not more than 3 mm, so it is better to remove excess clay immediately. In some cases, the seam thickness is even 5 mm.
The brick must be placed immediately in the right place, its further movement and tapping is unacceptable.
Excess clay mixture removed from bricks cannot be reused.
Below is the instruction for masonry:
It will take a lot of free time to lay a brick oven for your home with your own hands. Each brick has its own importance.
If you approach the issue efficiently and responsibly, the end result will be warmth and comfort in your home.
