Ventilation in a sauna is a system that requires careful organization during arrangement. It is one of the most difficult. If you approach this issue correctly, you can protect a person from carbon monoxide when heated by a stove, ensure a comfortable stay inside, and also guarantee economical fuel consumption. In the presence of a ventilation system, air flows are distributed evenly, and the walls of a wooden building are protected from decay and waterlogging.
Features of the arrangement of the ventilation system
Ventilation in the sauna can be supply and exhaust, or rather, mixed. At the same time, both the exhaust and the air supply are organized. To do this, there must be inlet inlets, which are also called vents. Fresh air enters through them, and if necessary, you can additionally install a ventilation pipe with a fan.
Air can also enter through half-open doors and vents. The system assumes the need for holidaysexhaust holes. Through them, the heated air leaves the room or through the stove blower. This is a hole that is located below the firebox and is adapted to improve traction. The supply and exhaust openings can be located in different ways, but the most effective way is the principle in which they are located in the lower part of the room. It is necessary to place them closer to the heater, in this case the air will heat up faster.
Nuances of the work
Exhaust openings can be located on the opposite side from the supply. They can be in two places, one of them is located above the other. This makes it possible to better control the air flow. If you need more intense traction, then the exhaust hole should be located higher. Otherwise, the draft will be weaker, and it is necessary to additionally use a ventilation pipe. The ventilation in the sauna can be controlled. To do this, use special doors or dampers that are installed on the exhaust openings. Be that as it may, the air inside should laugh completely once every 2.5 hours.
Technology for arranging a ventilation system for combustion in an adjacent room
Ventilation in the sauna can be arranged when the stove is lined with bricks, and the structure itself is made of metal. A space of 5 cm is arranged between the outer walls of the product and the shirt. When the tube is led into an adjacent room using a furnace tunnel, then thisoption has many advantages, which are expressed in:
- no garbage;
- possibility to install heat-resistant glass in the firebox door;
- no need to open the doors to the steam room again.
Such a ventilation device in a sauna involves lining the furnace tunnel with bricks. Bas alt wool is placed in the gap, since when expanding, deformation and destruction of the masonry or tunnel is possible. Next, you should proceed to the air inlets, using one of two methods, the first of them involves conducting a ventilation duct under the dome from the street, while the second involves arranging a ventilation duct above the floor.
In the first case, a channel is used, the diameter of which will be 120% of the diameter of the chimney pipe. This node is displayed at the pre-furnace metal sheet, which protects the floor from fire if the coals fall out of the furnace. From the outside and from the inside, the channel is closed with ventilation grilles.
When the ventilation system in the sauna is equipped with the second technology, the technique will differ only in the location of the ventilation duct. Otherwise, the knot is led from the street and displayed in the same place.
Specialist recommendations
At the next stage, you need to make a hood, which is located on the opposite wall, it should go diagonally from the air inlets. Vertically, for this you need to install a ventilation duct 30 cm above the floor level. Under the ceiling through the wall, it should be taken out into the street, andsheathe the box itself with clapboard.
For reference
If you are thinking about how to properly ventilate a sauna, you should remember that the area of the exhaust vents should be equal to the area of the supply air vents. Otherwise, draft may be generated and the amount of fresh air will be reduced as a result.
Arrangement of the ventilation system when the firebox is inside the steam room
In this case, you can use one of two technologies. The first allows you to resolve the issue automatically if there is a stove in the steam room, and air enters the blower. Fresh streams will enter through the open door, it will only be necessary to leave a 5 mm gap. This method is suitable if the fire is constantly maintained, which ensures the operation of the blower.
Before you make ventilation in the sauna, it is necessary to determine whether there is a chimney inside. This method is also suitable in the case when the sauna is operated by a short-time stove. At the same time, it is necessary to equip more perfect ventilation, the method of creating which will be described below. At the first stage, a podium is created for installing the furnace. This will lead to the design of the box. To do this, lay out three rows of bricks on the edge from the wall. It is necessary to carry out work in the place where the supply ventilation openings are located.
The first row is laid against the wall, the second row is along the edge, while the third is in the center. The masonry should be 24 cm high, it must be brought up tobrick screen. Next, you should equip the brick floor. The last pair of products is not installed in the place where the furnace will be located. It is required that it be blown into it from the box.
Work methodology
Ventilation in the sauna, bath is equipped according to the same principle. At the next stage, it is necessary to close the end, and then take up the second box. A basement stove door is installed in its end part, under which something should be placed, otherwise it will rub against the floor. The first box should look up, the second - into the steam room. On the wall adjacent to the rest room, a second channel is made for the doors at the level where the stone masonry passes. The doors should not reach 12 cm to the upper edge of the brick shirt. If necessary, they can be opened to warm the adjacent room.
Proper ventilation of the sauna at the next stage involves the need to install the stove on the podium. You can place it on metal plates or corners to distribute the load. The stove should be overlaid with brick, leaving a hole for the fuel channel. A gap of 2 cm is left between the oven and the brick, which is then closed with non-combustible material. At the next stage, you can start laying the brick screen, in which you should make two valves in the form of doors. Exhaust ventilation in the bath, where the folder is located outside the steam room, is arranged according to the same principle.
Features of the arrangement of the ventilation system throughproducts
Do-it-yourself ventilation in the sauna can be well equipped by any home craftsmen. However, certain rules must be followed. They say that the exhaust outlet can be placed under the ceiling, giving it a size of 15-20 cm. It can be made round or square.
You can close the hood with a sliding damper or a removable plug, with which you can change the degree of air exchange. Ventilation openings must not be located opposite each other. At the same time, fresh air will immediately fly out into the hood. This will prevent air circulation and cause drafts. The dimensions of the hood must match the dimensions of the inlet or be larger. If the dimensions deviate downwards, clean air will not flow.
If you want to increase the outflow of exhaust air, then the hood should be larger than the supply vent. As an alternative solution, you can consider the option in which two hoods will fall on one inlet. For the inflow of fresh air, an inlet should be equipped, which is located 0.3 m from the floor surface. You can place it on the same wall as the hood. The air inlet is also closed with a ventilation grill so that the air enters in streams, and not in a continuous stream.
Conclusion
Natural ventilation, which is most often equipped in a sauna, has many advantages, among them are easy installation, low cost, economyin operation, simple arrangement and reliability. Due to the fact that there are no mechanical devices in such systems, they are almost eternal, do not break down and do not need repairs.
However, the disadvantages should also be highlighted, they are expressed depending on the intensity of ventilation on the temperature difference in the steam room and on the street. In addition, smells from the street sometimes come in, and in winter and autumn, cold air lowers the temperature in the steam room, which is accompanied by drafts.
