Stainless steel bath stoves

Types of materials

To create a furnace for “Russian-style bath” use a special alloy (corrosion-resistant). In its composition are present alloying components. The main element is chrome.

The steel also includes nickel, titanium, Cobalt, manganese and molybdenum. When buying materials for making a stove made of “stainless steel”, the buyer should pay attention to chromium (not less than 13%).

stainless, steel, bath, stoves

As for the other alloys, their functionality lies in the following characteristics.

  • Nickel gives the product elasticity and increases resistance to stress.
  • Cobalt “responsible” for high heat resistance.
  • Silicon in the furnace steel increases the pellet strength of the alloy. This property is especially important for bath stoves.
  • Manganese is responsible for the elasticity of steel, which helps it avoid damage from temperature changes.
  • Titanium increases strength and corrosion resistance.

Stainless steel stoves. the best performance

Today stainless-steel furnaces are rightfully considered one of the best on the market. Judge for yourself: the heat resistance of such bath stoves is as much as 800 degrees! This is 200-300 degrees higher than the maximum temperature inside the sauna stove. That means that such furnaces will not develop scale.

Burning temperature of stainless steel furnaces is 800 degrees Celsius. Thickness. 2-6 mm.

The high temperature of heat resistance determines that the furnace will serve faithfully for a very long time. over 20 years! durability is not the only advantage of these stoves: they are not fragile, quickly heat the sauna, and are available in various designs.

The only disadvantage of stainless steel furnaces is ), but models of 4-6 mm thickness are still on sale. thickness (from 40 thousand).

By the way, we did not stipulate at the very beginning that this article will talk about stoves for baths, not for sauna. If you have not got into this question yet, you can read our article: “What is the difference between bath and sauna stoves”.

Metal stoves for baths and saunas

Company-manufacturer “Teplodar” offers to buy functional models of metal stoves of long combustion for baths and saunas of stainless or structural steel: 14 basic lines and their modifications are presented in assortment.

Steam mode

Your sauna heater must be able to produce and maintain a defined steaming regime. There are two main types of microclimates:

  • Russian bath microclimate. high humidity and average temperatures
  • The microclimate of the Finnish sauna. low humidity and high, sometimes forbidding, temperature

But the understanding of an ideal climate may differ greatly among the lovers of bathing traditions.

For a sauna, it is important that the stove is able to burn intensely to maintain a high temperature in the steam room. That is why it is so important that the furnace of the sauna oven is sufficiently heat-resistant.

Steam quality is very important in a Russian bathhouse. If there is a saturated mist hanging in the sauna, it is likely that the water has not fully evaporated. such steam is called heavy. An invisible veil of light steam at a temperature of over 100°C, which makes the bathing experience most beneficial and pleasant.

Types of stoves

    equipped with a peorized convector, created by a patented technology: it provides rapid heating of the steam room through the circulation of hot air.

  • Stoves with a closed heater or combined heater produce light and invisible steam due to the high temperature of the stones. about 650°C.
  • Stoves with open heater allow to heat up a steam room to high temperature and keep it for a long time, take up little space and are easy to assemble.
  • Stoves for a steam room up to 10 m 3
  • Stoves for a steam room of 12 m 3
  • Stoves for the sauna 16 m 3
  • Stoves for a steam room by volume of 20 m 3
  • Stoves for the steam room with the volume of 24 m 3
  • Stoves for steam rooms up to 40 m3

Type of fuel

Stoves are divided according to the type of fuel, suitable for use. In the range of the company Teplodar are:

    – Wood and coal. Easy to assemble and operate, have low demands on the quality of fuel used. Stoves work off-line for a long time on one load of wood or coal.

  • Gas stoves are highly efficient and economical, allowing you to save money on fuel purchases. Rooms equipped with gas-fired stoves heat up quickly and retain heat for long periods. A good choice for fans of Finnish saunas. They don’t need a special chimney and allow for automatic adjustment of temperature conditions.


Teplodar” company was one of the first on Russian market to start producing stoves for baths and saunas with stainless steel furnaces, which made metal stoves more durable.

In the production of “Teplodar” furnaces the following types of steel are used:

Steel Type Thickness, mm chrome Application
AISI 409 2 up to 13% Furnace walls
AISI 439 2,5 from 17% The most thermally stressed parts of the furnace, such as flame arrestors and the bottom of the sauna heater
AISI 439 4 over 17% PROFI series fireboxes
Steel 08 PS 3 Furnaces of budget versions of household furnaces
Steel St3sp 4, 5 or 8

The main property of stainless steel is its resistance to scale formation when exposed to high temperatures:

  • Steel AISI 409 is heat-resistant up to 750 ° C, and you can also occasionally use the furnace heated to 815 ° C;
  • AISI 439 is restricted to 850 °C.

Heat-resistant properties are due to the presence in the composition of steels a large amount of chromium, which does not allow oxygen atoms to react with iron.

Stainless steel for baths: features and selection criteria

Until recently, the main material for internal design of the bath was fireclay brick, which was used for assembly of the stoves. Thick-walled cast-iron tanks, in which the liquid was heated directly from the fire in the furnace, served as hot water reservoirs.

Today, however, the traditional materials are being replaced by modern counterparts, among which stainless steel stands out.

Stainless steel, also known simply as “stainless steel” is an alloy of iron with special alloying additives, which give the material anti-corrosive properties. It is not exposed to high humidity and aggressive chemicals, which means that it does not have to undergo regular maintenance.

In the bath, stainless steel is most often made of stoves and hot water tanks, which have fully adopted all the useful qualities of this material.

However, like any other material, stainless steel has its own unique properties, which may not always be appropriate in certain cases. In this article we will look at the main properties of stainless steel as part of the functionality of the bath.

It will be especially relevant to those who furnish the steam room with their own hands, because getting professional advice from a specialist is not always possible.

The heater is easy to install. factories produce fully assembled products, you just need to choose a suitable place in the bath room, prepare a flat area and make installation. Stove for a Russian bath on wood from stainless steel has an increased thermal conductivity, due to which it is extremely quickly heated and turns into a very powerful steam generator. over, stainless steel. heat-resistant material, perfectly suitable for daily thermal loads, as in a professional bath or sauna. Stainless steel furnaces are absolutely safe to use. during its operation a minimum amount of oxygen is burned, so it is easy and free to breathe in the steam room. Such heating equipment is practically not exposed to burning, which means that the owners faithfully serve their owners for at least 20 years.

Depending on the design, stoves can be closed and open, with standard and remote furnace, with a water tank or without it. In the catalog of the online store “Heater” is represented equipment of various configurations for heating steam rooms with a volume of 9 to 28 m³. We offer for sale the standard budget models, as well as original design solutions the premium class.

In comparison with cast iron and stone furnaces, stainless steel units are the most cost-effective and fastest way to qualitatively equip the steam room. Domestic market offers a huge range of oven products from different manufacturers. “Termofor”, “Teplodar”, “Vesuvius”, “Ermak” and TMF. Choose the right option, if you have any questions, please contact our consultants for assistance!

Choosing a sauna heater it is worth paying special attention to the thickness of its metal walls, and whether it suits the size and heat output of the specific steam room. If you can’t choose, please contact with consultants of the Internet-shop “Pechnik”. They will choose the best variant according to cost and technical characteristics.

The main advantage of stainless-steel sauna stoves is the possibility of installation with protective brick screen, which makes the operation of the stove safe and the stay of visitors in the steam room. comfortable. Steel oxidation resistance (up to 850 ° C) and high-temperature corrosion resistance of stainless steel allow furnaces to work successfully for decades, unlike conventional steel and cast iron, whose life is greatly reduced if used brick lining.

In the production of sauna stoves different stainless steels are used, such as AISI 439, AISI 304, AISI 201, AISI 430, which have different set of characteristics important for stove construction. Teklar sauna ovens are made of AISI 430 stainless steel. This ferritic high-chromium heat-resistant steel (Cr 17%) is the best combination of properties which allows to create reliable, durable products. The thicknesses of stainless steel used are optimally matched to the various components of the design and vary depending on the stove series (“medium”, “heavy” or “extra heavy”) from 4 to 10 mm.

In addition to the key properties of. scale resistance and high temperature corrosion resistance. The stainless steel grade used has a low coefficient of thermal expansion and increased thermal conductivity, there is no thermal hardening. All these factors combine to ensure reliable and long-lasting operation, eliminating burnout of the furnace walls and possible deformation of the structure at high temperatures, increasing the efficiency of the furnace, reducing the time to heat up the steam room, making the furnace more economical.

The austenitic structure of weld metal in Teklar stainless steel furnaces is achieved by careful selection of welding materials using the most modern metal processing technologies, ensuring the highest quality of products and high reliability under continuous alternating loads. High-alloys with high chromium and nickel content are used as filler material to ensure the best characteristics of the weld: high strength, toughness, corrosion resistance under continuous high-temperature operation and abrupt changes in temperature.

The qualities of stainless steel that affect the durability and reliability of Teklar ovens:

  • Resistance to scale formation up to temperatures of around 850°C prevents burning of the furnace walls.
  • High-temperature corrosion resistance provides long-term operation in the gas environment formed by combustion of various fuels.
  • Low thermal expansion coefficient eliminates significant deformation of the product during operation at high temperatures occurring on the body of the furnace installed in a brick case.
  • Increased thermal conductivity (higher efficiency, faster heating up of the sauna, better economics).
  • Lack of thermal hardening ensures reliability of the welds in the steam room of a Russian bath with its characteristic harsh operating conditions of the furnace.

Stove must be installed in the bath!) together with a protective screen of brick, stone or other ceramic materials, which makes it possible to combine the advantages of brick sauna stoves and wood-fired metal bath stoves. Therewith Teklar sauna ovens are much superior to traditional brick ovens in basic operational features: the speed of bath preparation (1-2 hours vs 4-8 hours in traditional brick oven), no strict rules of heating (violation of which often leads to rapid failure in conventional brick ovens), minimal maintenance between firing.

Stainless steel came to replace the traditional materials, and its use in the production of bath stoves made it possible to greatly simplify the construction of Russian baths, to accelerate the preparation of bath procedures, to increase reliability and to prolong the life of the stove for many years. Installing a protective brick screen together with a stainless steel stove creates an efficient, controlled convection system to regulate the temperature in the steam room based on the preferences of sauna visitors.

Stainless steel Teklar sauna stoves take up little space in the steam room. The furnace is fired and serviced from an adjacent room (pre-bathroom, rest room, etc.).д.). If necessary, you can install the stove with the furnace from the steam room, from the street, etc.д.

Stainless steel AISI 430 is used in food industry. Therefore, a sauna heater made of it produces steam free of impurities, oxidation products, and side odors. It is impossible to turn water into pure steam when using ferrous (unalloyed and low-alloyed) steels and currently popular cast iron.

We offer stainless-steel bath stoves for domestic steam rooms up to 16-35 m³ volume in our store catalog.cube (stoves Ira, Hangar, Etna), and for large steam rooms up to 63 m.cube (Erebus stoves). Models are designed for family, guest or club baths of different volumes. Models of stainless steel stoves for public baths are also available.

If you buy a stainless steel stove you can be sure that it will serve in your bath for many years delighting with its work and bringing pleasure of using the sauna to all visitors of the bath. Both for lovers of soft modes and for those who like “hotter”!

Question 6. Where shall we heat it from??

We have in our assortment stoves with remote furnace and stoves without remote furnace. Most likely there will be at least two rooms in the bath, and it is more convenient to heat the stove from the adjoining room, because it is convenient and less dirty from the firewood in the steam room. Well here we have reviewed the main modifications of stoves that are now produced for the bath. For more longevity, let’s give more recommendations for stoves:

Stove for the bath

Company 95 degrees has the best wood-burning stoves for baths from well-known Finnish and Russian manufacturers in its catalog. You can find the best and right stove model from all of these options.

Important points when selecting a wood stove

Steam room volume. This is perhaps the main point to which you need to pay attention when buying a sauna stove. Capacity of the stove is determined by the size of the steam room.

Type of sauna heater. In simple terms, they can be called open, closed, and combined. In open heater, as the name implies, the stones are open, so you can’t raise the humidity with these stoves. Enclosed heater allows you to not overheat the air and create a mode of Russian baths with high humidity.

Steel. Most ovens are made of steel. Their main advantage is an affordable price. Pay attention to the steel thickness.

Cast iron. Cast iron is characterized by high heat capacity and durability.

Stainless steel. Stainless steel furnaces are more expensive than usual, but they have a longer life.

The manufacturer. We represent the world’s most popular manufacturers of wood-burning stoves. These are the Finnish leaders Kastor and Harvia, as well as domestic Varvara, Vesuvius, Ermak and Gefest. Also in our catalog you can find stoves from the following manufacturers: Tulikivi, Teplodar, EasySteam, GreiVari, TMF, Koster, Klover, IKI, Thermofor, Fehringer.

All of them have excellent characteristics and reviews, so we strongly recommend them to our customers.

Number of stones. Wood stoves can hold from 20 kg to several hundreds of kg of stones. The larger the capacity of the stones, the more time it will take to heat it up. However, when succumbing to the temperature of the stone will quickly recover and you can catch the moisture.

water tank. Some models of the sauna heater have a built-in tank, while others have this as an optional extra. You can also buy a tank on the chimney pipe.

Type of door. Come in blank metal or cast iron and with a variety of glass options, from small to large fireplace windows.

Type of furnace. You can heat from either the cabin or the anteroom. For the second variant stoves have an extended tunnel (remote furnace) for passing through the wall.

The efficiency of the sauna stove and its service life depends on the choice you have made.

Steel stove

Today’s metal bath stove bears little resemblance to the once-popular burzhuyka, which consumed an obscene amount of fuel and did not give much heat. The simplest structurally heating device, which was a metal box with a pipe and a door, is a thing of the past, and in its place have come perfect stoves with maximum technical advantages, easy to use, safe and durable.

Modern steel stove for practicality and its own possibilities leaves behind not only the primitive heating devices of the past, but also makes an annoying competition to the traditional brick masonry stoves.

  • High speed heating of air Once the fuel is lit, the steel stove begins to heat the room, which takes about an hour, while the brick oven, in turn, after firing it will take time to heat up many times more.
  • Good heat output The steel oven has an impressive efficiency rate; the degree of heating of the metal frame is, for obvious reasons, much higher than the heating capabilities of a brick structure.
  • Simple installation Bath stove made of metal does not require construction of the foundation; having enough light weight, it is installed in any convenient location in the steam room.
  • Compactness Perfectly fits into small rooms, as it has a very modest size.
  • Economical fuel consumption Compared to brick stoves, steel ones consume considerably less firewood and work efficiently on a single load of fuel for up to ten hours.

In most cases, the stoves are made of steel and have a chamber for placing stones. Depending on the model, metal sauna stoves can be equipped with a water tank.

There are three types of steel furnaces: closed, open and combined. Given the requirements for heating devices and the specifics of bath premises, experts choose the optimal model of metal stoves.
