Sauna stove dimensions

The main criterion when choosing a stove for a sauna is power. If there is a lack of it, the room will heat up for a long time and cool down quickly, and the equipment will fail in a short time due to constant overloads. If the power is higher than necessary, then the temperature in the steam room will rise quickly, but the stones will not warm up, and it will not be possible to obtain balanced steam. Therefore, when choosing a heating device, you need to decide in advance on its size.

What determines the size of a sauna stove?

Power is not the only criterion when choosing a sauna stove. There are many more factors that influence the dimensions. These include the following:

• iron or brick stove;
• Type of fuel;
• firebox design;
• room layout and finishing options;
• what kind of heating is used: cold or hot;
• heater type: closed or open;
• Duration of operation on one load of fuel.

Only the combination of all these parameters will allow us to correctly determine the real size of the structure.

How to correctly calculate the size of a sauna stove

Its dimensions depend on the power of the heating structure. The higher this indicator, the more fuel needs to be burned, therefore, the volume of the firebox must also be appropriate.When calculating power, the volume of the room is taken into account. What influences its heating? First of all, this is the ambient temperature and the quality of the thermal insulation of the walls.

On a note! For a bare log house without insulation, it is necessary to use a magnifying factor.

First, calculate the volume of the room. To do this, multiply its length, width and height. We divide the resulting value by two and obtain the conditional number of kilowatts required for heating.

In addition, it is necessary to heat the stones for the steam room and water for washing. In this case, part of the heat will fly out into the pipe. Therefore, the estimated number of kilowatts should be multiplied by 2.5-3. This is a calculation option for the case if the walls of the steam room are insulated and it is not combined with a washing room.

If the log house is bare and there is no thermal insulation, then we multiply the resulting value by another 1.5.

Important! Such calculations are very approximate, since there are no exact coefficients.

Now you can calculate the volume of the firebox in liters. To do this, the power must be divided by 0.5 or 0.6. To find out its linear dimensions, you need to take the cube root of the obtained value. After the calculations have been made, it is not difficult to imagine the dimensions of the heating unit itself.

What is the optimal ratio between the size of a sauna stove and the room?

For optimal air heating, the sauna stove parameters should be as follows:

• the ratio of the size of the firebox to the area of ​​the heated room is 1:50 or 1:70;
• combustion hole depth - 1:2 or 2:3;
• The volume of the firebox to the chimney cross-section should be in a ratio of 1:10.

The most common sizes of sauna stoves:

• Power 16 kW, firebox size 55x55 cm. They are used in rooms with a volume of 20–22 m³. The height of the heating unit is from 89 to 143 cm. The capacity of the heater is from 60 to 150 kg of stones.Such a stove, with the same power, can produce more steam.
• Power up to 28 kW, combustion hole size 63x63 cm. With similar firebox volumes, heating a steam room with a volume of up to 35 m³ will take an hour and a half. Furnace height from 98 to 158 cm with stone loading from 70 to 170 kg.
• Power 40 kW, firebox size 73x73 cm, heater capacity - 250 kg. Capable of heating rooms up to 50 m³. This unit allows you to steam for six hours without additional fuel loading.

What size should a metal sauna stove be?

The range of metal heating units for baths on the modern market is large. Usually these are steel or cast iron structures, which can be wood, gas, or electric. When buying a ready-made stove, you do not need to make any calculations. The manufacturer did this for you. The passport indicates the power of the device, dimensions and recommended room volume.

For a Russian bath, depending on the model, the dimensions vary: length from 400 to 680 cm, depth from 415 to 900 cm and height from 700 to 1600 cm.

What should be the size of a brick stove for a bath?

Brick structures are more diverse in terms of volume and design. What needs to be remembered when laying such a stove is the standard size of the red brick, which has dimensions (250 x 120 x 65 mm). The base is usually laid out in 3.5 by 4 bricks (89 x 102 cm) or 4 x 5 bricks (102 x 129 cm). The height excluding the pipe is 168 or 210 cm.

Most often, the water tank is installed directly into the stove.

Practical advice on how to select the size of a sauna stove

There are several key factors to take into account.

• The most important thing is that the dimensions of the heating unit correspond to the size of the room.For a small steam room, you should give preference to a compact model, this will protect you from contact with a hot surface and protect you from burns.
• The design must be thought out in advance to make it easier to work with heating elements and to be able to regulate the temperature.
• The power should be sufficient to heat the room well and generate steam.
• To exclude the possibility of spontaneous combustion, it is imperative to comply with all fire safety rules regulated by SNiP 41-01-01.

The dimensions of the sauna stove are an important aspect that you should pay attention to. Take a responsible approach to the manufacture of this element, and your bathhouse will become a place of better relaxation.
