Gas-fuelled Sauna Stoves for the Home

Gas is the ideal alternative for a home outdoor sauna, in places where there is a need to avoid the emission of smoke or the electrical voltage required for an electrically powered furnace is not available. The stove is fitted with an automated gas burner. In all other respects, the furnace construction is very similar to a wood burning stove. Naturally, all the virtues of a traditional stone stove are preserved. Gas-fuelled stoves can even be created for large commercial saunas which require more power than a sauna in the home. A gas-fuelled stove is totally safe due to the fact that the lighting and heating process is completed before the banya sessions begin.

A truly authentic Russian banya stove is one of humanity's greatest inventions. People who experience a Russian banya feel totally renewed and given a new lease on life. Steaming in a Russian banya awakens vitality, lifts the spirits and brings body and soul into harmony.  Regular use of a Russian banya restores health, aids weight loss and gets the body working like clockwork again.

Many find the Russian banya to be the most powerful and effective SPA programme of all. Its beautifying and detoxifying action works from the inside out and so results in long-term effects. That said, even after your first banya session you will notice its instant positive results.

The interior of a Russian banya consists of a vaporarium, a plunge pool, a shower unit and rest area. The sauna room will embrace you with its light steam and gentle heat. Here you can warm yourself through and indulge in "parenie", a thermal message using a "venik", a special sauna switch made of aromatic leaves. The plunge pool cools the body and the shower purifies. This is followed by rest. Then you repeat the cycle again allowing the banya to transport you into realms of delight. Welcome to nirvana!

The stone sauna stove is without question the heart of the vaporarium and the main attraction of the traditional Russian banya.  The gas-fuelled stove is fitted with an automated gas burner and flue pipe. All stoves produced at Furnace Art Engineering have a number of quite unique properties due to the technical perfection of our design.

A gas powered stove will suit you if wood smoke is to be avoided, you want to build a sauna in your garden and the spare electric supply circuit available is less than 12 kW, or the steam room requires a stove with increased capacity. Even if there is no mains gas supply the stove can be connected to an autonomous Gazgolder (private reservoir for storing liquid gas).

Functional features of a stone sauna stove

This type of solid stove emits a gentle, radiant heat that gradually warms the floor, benches, walls, ceiling and the bodies of the bathers inside. A stone stove will reduce air circulation in the sauna room to zero. Inside the stove there is a solid core which creates steam when water is splashed onto it giving out a characteristic ‘flap’ like the sound a very large bird makes when it flaps its wings. Consisting of stones and cast-iron ingots of a special size and shape, arranged in a particular manner, the core maintains a temperature of between 600 and 1000 degrees celsius.


So just how hot is a sauna stove? The stove is heated until such point as the entire mass has reached temperature and the inner core is glowing red-hot.  At this point the stove is left to stand for a while giving the steam room time to reach thermodynamic equilibrium: the stove surfaces, atmosphere, walls, floor and benches gradually reach exactly the same temperature at which point all air circulation in the vaporarium ceases.  At this point the stove is ready and will maintain a soft heat and produce light steam in the sauna room over the course of a number of days. Our stoves produce the famous light steam that is so precious to banya connoisseurs. Our customers enjoy a light steam that remains to this day unrivalled by any other sauna maker in the world.

Making the Stove

Unique features
Sauna stove production is an extremely specialised field.

In comparison to what is involved when we create a sauna for your home, a normal heating stove project is relatively easy to implement. A finished sauna stove must be capable of withstanding thousands of heating cycles that involve the fire-box walls being repeatedly heated until they are glowing red-hot. In order to obtain a light steam, the stove must have a red-hot nucleus at its centre. The nucleus’ heat and weight, quite apart from the periodic output of steam, places additional demands on the stove's construction.

Every stove is individually designed drawing on our considerable experience and developments in engineering, and with full compliance of national best practice guides for chimney and stove manufacturing, as well as up to date construction standards and legislation.
Calculating stove heat transfer
The parameters of a gas powered sauna stove such as power and weight must conform to the proportions of the steam room. The precise volume of the sauna room is arrived at by multiplying its total square footage by the ceiling height. In our experience, the ceiling height of the steam room should be at least 2.8 m (absolute minimum, 2.4 m), in order to give the light steam the ample space it needs to accumulate when water has been splashed onto the stones. Afterwards, it will gradually descend towards the floor. We also take the shape of the room into account although this is of secondary importance. The door and windows are also considered when determining the sauna room’s heat transfer factor. The stove must have the capacity to heat its own mass and core consisting of cast-iron and stones. The values of the stove’s mass, surface area and wall thickness will all affect the length of time the stove will stay at temperature and remain capable of producing light steam. Sauna stoves produced at Furnace Art Engineering will provide a steam session at any point over several days on a single heating - an exceptional indicator of performance.

We pay particular attention to the thermal insulation of the stove and the steam room itself. Although the stove's every brick is designed to work for the efficiency of the vaporarium, a certain amount of heat is transferred to other sauna rooms creating a pleasant atmosphere in these areas also.
Furnace location and foundation requirements
For the ideal fulfilment of these requirements, numerous factors must be taken into account. At the beginning of each new project our experts make a scrupulous study of the brief objectives, conduct an engineering analysis and produce a series of technical solutions which are applied to the stove model. We will always take pains to propose the optimal positioning of the stove in the sauna room. We take full responsibility for creating the best possible spatial layout of the sauna interior.

Benefits

For the satisfaction of guaranteed results, we strongly recommend choosing a 'turnkey' sauna.

  • Light steam guaranteed How hot is a sauna? The stove's stone mass and core, heated to between 500 and 1000 degrees celsius, is an essential requirement to the instantaneous transformation of water into superheated steam.   Splash water onto the stove and ‘whoosh!’, an invisible cloud of dry, light steam gushes out and upwards towards the ceiling. When a light steam is produced in the vaporarium,  you won't feel the humidity. You can breathe easily into the lungs and relax into the pleasure of warming the body. With a light steam you can indulge in the ultimate secret of the traditional Russian banya - "parenie". “Parenie" is a delightful thermal massage conducted with a "venik", a leafy, fragrant bundle of twigs. The electric box-heaters ordinarily installed in saunas are incapable of producing a light steam because they lack the mass necessary to do so and the rocks placed on top are "cold" (200 - 300 degrees celsius).

  • The stove ventilates the steam room This crucial function is dependent on special elements of the sauna stove design. Fresh air from outside the building enters the stove where it is heated and transferred to the breathing zone, the upper area of the steam room. At the same time, air from the steam room which is saturated with vapours is transferred out of the room and utilised. The intensity of the air exchange rate can be regulated via special vents that can be moved easily from one position to another using just one hand.

  • Stove usability All the stove's controls are designed to be so simple and natural to use that anyone can manage the stove settings the very first time they come to use it.

  • The stove’s automatic gas burner meets the most stringent safety requirements (gas pressure control, combustion flame control, etc.) and is equipped with a thermostat and a safety shut-off device. If the flame is extinguished, the gas supply shut-off device is activated automatically. The burner heats the stove's stone mass quickly and evenly. The equipment and installation both receive inspection and testing certification.

  • Power, efficiency and environmental friendliness A gas-fuelled stove has sufficient capacity to heat a steam room with a total floor area of up to sixty square metres.  Our gas-fuelled sauna stoves have an exceptional efficiency rate of up to 80%. A gas-fuelled stove can be fully heated in just five hours and brought up to temperature in as little as two to four hours on a night timer setting.  We only use environmentally friendly materials in the production of our sauna stoves. At Furnace Art Engineering we firmly believe that there can be no place for synthetics in a traditional Russian sauna.

  • Exceptional durability Rarely does an ordinary sauna stove last for more than five years without needing a complete overhaul. The stoves created at Furnace Art Engineering are the exception to the rule. The life cycle or ‘resource’ of our stoves is twenty years. How do we do it? There is a secret to creating such exceptional durability. The secret lies in conducting a separate engineering analysis and producing a unique design for every steam sauna for home use project we undertake. It also comes down to using only the highest quality materials available and the filigree work of our craftsmen. The most common cause of stove failure is lack of homogeneity in thermal expansion throughout the construction. Our tried and tested expertise ensures that our customers will never have to deal with this kind of issue.

  • Safety Our sauna stoves are fully heated before the steam session starts. Aside from that we can equip our sauna stoves and sauna rooms with thermal sensors. If a bather ever forgot to close the steam door and the temperature in the steam room exceeded safe levels, an alarm signal would sound. Thanks to the installation of sensors our customers can control the stove lighting process, heating regime and temperature of the core. Fire prevention is ensured via total compliance with building regulations and the conscientious use of insulating materials of the highest quality available.

Which Stove?

Choosing the right stove

The Russian banya’s well-deserved fame lies in its traditional brick stove. Above all else, we specialise in crafting bespoke traditional Russian stoves. The experts at Furnace Art Engineering are convinced that electric sauna heaters are an unsuccessful compromise. This is why:

Special features

An authentic brick sauna stove

An iron box ‘including rocks’ (an electric stove, wood burning, metal etc)

Design

A single, closed, monolithic design including the furnace, the cast-iron-stone core and casing.

A bucket "including rocks" can take various forms but the rocks are always placed on the surface.

Mass and heat absorptive capacity

Large-tonnage mass. The stove's high heat storage capacity.

Low mass, low heat capacity.

Safety of operating mode

Periodic use. The steam session only starts after the stove has been heated. The stove is never heated simultaneously to the bathing session instead giving out heat already stored beforehand.

Constant use. Always switched on or burning logs. Unsafe with hazard of electric shock or carbon monoxide poisoning (many examples and statistics).

What heats and how?

Radiant heat warms the floor, walls, ceiling and bathers. The stove surface remains at around ninety degrees celsius.There is no air circulation and it is safe to enjoy the steam session.

Heating elements and other iron objects dry out the air which is breathed in by the bathers. Air circulation raises the temperature on the surface of the skin to above 60 degrees celsius initiating burns.

Light steam

Produces light, dry steam. The bathers warm through gently and breathing is easy. The body works like clockwork.

"Cold" stones. Wet steam. High humidity levels impede the evaporation of sweat - a potential cause of heat stroke.

Temperature of floor and ceiling in the steam room.

Identical temperatures. Minimal air flow. The body warms up gently and evenly.

It is 50 C warmer at the level of the ceiling then at the floor. Hot air currents. The head is hot but the feet are cold. This can quickly make you ill. Analogy to a hot workshop in the production of harmful materials. Pneumonia.

Research

WBGT  Index  (Wet-Bulb Globe Temperature, according to Horace Middleton Vernon) from 52 to 58. Supportive to the health.

WBGT index no more than 33. To increase the index rating humidity levels are raised involving the installation of another electrical appliance - the humidity generator.

Who buys them and why?

For those who understand the difference there simply is no alternative to a traditional Russian sauna stove.

Customers swayed by advertising and lacking information.
