For heating a country house or a dacha they often use a "Dutch" - a furnace built from solid ceramic brick. Its advantages are obvious:
- ease of assembly;
- takes up little space;
- warms well both large and small rooms;
- after burning fuel stove remains warm for a long time and maintains a sufficiently comfortable temperature in the room.
The Dutchman can also be built by a novice with its own hands, but it must be carefully prepared for its construction. The design of the furnace includes:
- chimney system;
- adjustment of smoke output.
The heating section
In the fuel chamber - the firebox - there is a combustion of fuel and smoke gases, rising and falling on the elongated system of chimneys, more fully give off their heat. The speed of the smoke can be adjusted using a special metal flap.
In the classic Dutch design, only the fuel door is provided, but modern stoves of this kind are still equipped with a door for blowing. In addition, the grate has been added to facilitate the removal of ash and the laying of new fuel.
The simple design of the stove allows you to fold it even without any experience in mounting the stove.
- For the construction of the Dutch woman, it is required to initially prepare the foundation - at least a week before the start of installation. To do this, determine the size of the stove. The size of its base should be somewhat larger.
- At the installation site of the stove, you need to disassemble the floor and prepare a pit with a depth of at least 50 cm. If the foundation for the “Dutchwoman” practically rests on the foundation of the house, a sandy layer should be laid between them.
- Having made a cement mortar (cement, water and sand in the ratio 1: 3: 4), place it in a small layer in the prepared excavation. Then they put a reinforcing grid of metal rods that are not less than 1 cm thick. Finally, pour the remaining cement mortar flush with the floor. From above, after the completion of the construction of the Dutch basement, the laid solution is sprinkled with sifted cement powder.
- During the week, the foundation should harden.
The order of laying bricks
- The thickness of the walls of the "Dutch" is one brick.
- Having laid the waterproofing material on a frozen foundation, you need to pour a thin layer of sand on top of it, and lay the first row flat on the first brick soaked in water, keeping a small distance between them. When laying the kiln itself, a clay-based mortar is used: a mortar is applied on top of the lined bricks, which is gradually lowered into the space between the bricks. All the following rows are bound with the solution as usual.
- Dutch masonry Immediately after laying the first row, it is necessary to stretch the ropes vertically from the corners and center of each of the 4 walls to keep the dimensions of the “Dutch” and lay it out straight.
- The second row is required to be laid out entirely, with a shift to the floor of the brick relative to the bricks laid out along the perimeter of the first row. In the third row is required to equip the door blew. Since the ready-made metal door is used, it is necessary to leave a place both in the horizontal row and in the vertical one for mounting the door. Between the fourth and fifth rows, it is necessary to lay the grate with the possibility of its subsequent replacement, and starting with the 6th row, it is required to begin to lay out the fuel chamber, including its door.
- The walls of the fuel chamber should continue to spread up to the 13th row inclusive.
- In the 14th and 15th rows, it is necessary to arrange the overlap of the firebox, laying bricks on the edge. Further, with the help of bricks placed on the fins, an elongated chimney is formed, along which smoke will rise as wood or coal burns in the fuel chamber.
- If you need to build a compact "Dutch", then its chimneys with the help of a special technology, the calculations seem to be rolled into a ring. When installing a large stove, a long chimney is located without collapsing, and thus, the classic “Dutchwoman” takes up quite a lot of space.
- Finally the long chimney comes down to the chimney, going out through the roof. In the area of the roof, it is necessary to lay the bricks flat again, thus reaching a greater thickness. In addition, insulating materials should be used to prevent overheating of the floors.
- Operation of the "Dutchwoman" is possible already after 2-3 weeks after its laying out.
