Design features

As you know, the main purpose of the furnace is to heat the steam room building for a specific time. In order to work with maximum heat transfer, they are equipped with the following structural elements:

The stove is the main attribute of the stove. Its purpose is to maintain a stable flow of heat, which is carried out due to the mass of stones that gain heat from burning wood.
Chimney... It is presented in the form of a pipe that comes out of the furnace and removes the combustion products outside. In view of this, wood-fired sauna stoves with a water tank are of low efficiency.
Door with a through tunnel. Designed for the ability to heat the bath with wood in the next room, or in the dressing room.
Heat exchanger. Installed for the purpose of heating water during heating.
The firebox is a site for heating fuel, heat energy is immediately released. Often, the grate is mounted in it in a different position, which depends on the type of fuel. For firewood, the grate must be positioned at the same level as the door firebox. Bevels are also made on three sides to roll the combustion products forward.
Ash pan. Place under the grate in which the ash is located.

Furnace components

How the oven works

Almost all wood-fired heat sources function according to this principle: first, firewood is placed in the firebox, which heats the equipment, and its walls produce heat transfer. As a result, the room is quickly heated, but at the same time the temperature does not last long, which is why it is necessary to constantly lay firewood.

Helpful information! Most often, firewood is set on fire from below. Since the fire quickly rises, and as a result, only coals remain, it is necessary to throw fuel in a timely manner.

Principle of operation

Long-burning heating devices differ from traditional stoves in the possibility of long-term heat transfer without the need for frequent throwing of firewood. The intervals between tops are about 20 hours. Such furnaces work according to the principle, a feature of which is the reverse direction of the combustion process, that is, from top to bottom.

Construction requirements

The best type of wood-fired sauna stove with a water tank is equipment that is easy to use, compact, economical and aesthetically pleasing. Firewood and processing are recommended as fuel. Here is a list of the prerequisites that any oven must meet:

wide range of heat transfer power, which will be enough for heating baths... It should also be noted that the power for heating may not be enough, depending on the type of construction of the steam room;
the obligatory presence of a steam generator and a heat generator, allowing you to regulate the power of the furnace;
built-in convection control devices;
high-strength coating.

The simplest and most reliable design

Helpful information! Subject to these requirements, a wood-fired sauna stove with a water tank will provide excellent heating and proper safety.

There are also requirements for the equipment in terms of fire safety:

the presence of a solid base of fireclay bricks or concrete;
the oven cover should be as even as possible;
the wall for the external door must be made of non-combustible material;
the gap between the door and the opposite wall must be at least half a meter;
the location of the furnace should be such that the side walls are at a distance of half a meter from the combustible structures;
the floor near the stove should be finished with fireproof material.

Types of wood-burning stoves for a bath

Wood stoves for a bath with a water tank can be of two types, depending on the base material:

Metal ovens. Cast iron and steel devices are represented by a wide range in the modern construction market. The shape can be rectangular or square. They can be equipped with doors, heating tanks. Among the advantages of steel and cast iron stoves, the following are noted: affordable price, simple installation, no need for a strong base, quick heating of the room, the ability to install a tank on a chimney. Among the disadvantages are the rapid cooling of the stove and the instability to temperature extremes.

Metal oven

Brick stoves for a wood-fired sauna with a water tank. Brick devices are devoid of metal drawbacks, because they retain heat in the steam room much longer and have a long service life. Their solid appearance is especially appreciated.

Brick oven

Brick stove-heater

Brick oven scheme

Helpful information! Among the disadvantages of the brick version are the high price, the complexity of construction and the need for a special base. It is also worth noting the need for more fuel.

Tank placement options

Heat exchangers are often made of stainless steel with an enamel coating. The location of the tank is of great importance, here are the main options:

internal (built into the firebox);

Sauna stove "Siberia" with a built-in tank

Hinged (attached to the body);

Wood-burning stove "Varvara" with a hinged tank

Remote (heated from the smoke outlet);

Remote tank heated by a chimney

Remote (heated from the mounted tank to the firebox);

Remote tank heated from the firebox

Helpful information! It is not recommended to equip brick ovens with a remote tank heated from a chimney, therefore, you can often find it with internal and hinged heat exchangers.

Popular models of wood-burning stoves with a heat exchanger

This list contains the top most demanded wood stoves for a bath with a water tank:

Teplodar "Sahara 10 LB". The equipment is made of steel. Design features: painted convector and an external door with a through tunnel. Designed for heating small rooms with a size of 4-10 cubic meters. The construction has a domed heater and a chimney. The firebox is carried out from another room. The advantages of the furnace include resistance to burnout and dross formation. The package includes a hinged heat exchanger with a capacity of 33 liters.

Lineup "Sahara"

Stove-heater "Kolibri 9B". Designed for heating the steam room for individual use. The package includes a hinged built-in heat exchanger. The equipment is made of stainless steel. Among the features of this model, it is worth noting the ability to obtain steam and hot water at the same time, to control the flow of liquid. The latter allows you to significantly save water resources during operation. The design is characterized by a minimum number of welds.

DIY step-by-step construction of a brick oven

The first stage of building a brick kiln is the foundation. The base for a brick wood-fired sauna stove with a water tank must be particularly strong. It is done this way:

dig a hole 3 meters deep and tamp the soil;
cover it with a layer of rubble and sand 100 mm;
make wooden formwork and reinforcement;
pour concrete mixture 1 meter thick;
stand until hardened for about 3 weeks.

Foundation preparation

The brickwork of the stove is carried out using clay mortar. The bricks are laid in accordance with the selected order, leaving a seam with a thickness of no more than 5 mm. It is recommended to build the base of the firebox from fireclay bricks... In order not to delay construction, it is better to first stock up on doors, latches, grates and a water register.

Tips for choosing

When choosing a metal oven, you must consider the following points:

thermal power. It is necessary here immediately calculate the area of the room... And already taking into account the area, you can choose the power of the furnace, one cubic meter is equal to one power;
tank for water. When choosing a container, consider the volume and method of its location. Experts recommend a hinged and portable tank with a volume of 50 liters or more.

Characteristics of tanks for metal furnace

It is much easier to buy a metal version of a wood-burning stove for a bath with a water tank and install it with a remote firebox. A brick oven will be much more expensive and more difficult to build. But the service life and quality of the firebox are better for the brick version of the steam room heating.
