A state of mind
Stûv - a state of mind
Since it was established in 1983, Stûv* has endeavoured to provide a
contemporary vision of wood-burning stoves. The subtle stylishness and
elemental design of the first Stûv stoves heralded the minimalist philosophy
which prevails today.
Stûv has always attached great importance to the functional aspects of its
stoves, and is responsible for numerous innovations which have profoundly
influenced the world of wood-burning stoves.
Today, more than ever, Stûv is looking for innovative solutions to integrate
renewable energies into the heating systems of tomorrow.
*Stûv is a Walloon term which means
“stove”. It is similar to “étuve” in
French, “stoof” in Flemish, “Stövchen”
in German, “estufa” in Italian and
“estufa”in Spanish and Portuguese …

Stûv 16/68-cube
More powerful, cleaner, quieter and
more elegant.
These compact stoves are a very
attractive, inexpensive and highly
efficient form of heating.
And in the energy-efficient houses
of the future, they are easily integrated
into state-of-the-art heating and
ventilation systems.

Stûv 16 is designed for environmentally
friend­ly operation. It uses a sophisticated
combustion technique enabling extremely
high performance to be achieved. It is preequipped for various types of connection :
It can therefore be integrated into a stateof-the-art heating and ventilation system,
but also installed in a very simple way.
The basic Stûv 16 does not even require an electrical connection as it operates without a fan.

2 variants :
stove or insert
The Stûv 16-in is a stove designed to be easily
fitted into an existing hearth or into a brand
new chimney. It is an attractive alternative to
a stove with a retractable door (page 16) if
you are planning to use it intensively or are
looking to spend less.
The Stûv 16-cube and Stûv 16-H operate like
normal stoves, giving off much of their heat
through their sides.

How does the Stûv 16 work ?
When the fire is burning, the logs produce
large flames and the temperature in the stove
is very high. This is necessary to ensure good
combustion to transform maximum energy
into useful heat and reduce emissions into
the atmosphere to a minimum.
Heat is mainly dissipated in 2 ways :
> by radiation through the glass,
> then by convection : the air circulates
in the double wall around the combustion
chamber and reheats before distributing
around the room.
1
Conserving heat
4
7
The chimney flue (1) is filled with hot gases
much lighter than the air outside and which
therefore only want to rise. We say that the
chimney “draws”.
The chimney in fact literally sucks up the gases
produced by the stove. However, the gases
and the heat that they contain must not be
allowed to escape too easily up the chimney.
6
5
3
2
combustion zone
convection zone
Two devices stop this from happening :
> At the entrance, the air required for
combustion (2) can only enter the stove
through a vent (3) – i.e. an adjustable
opening allowing you to control the
quantity of air required to obtain the desired
effect.
> At the exit, the hot gases cannot pass
directly into the chimney : they have to
follow a system of diverters (4), which
constitute a second bottleneck.
Thanks to these bottlenecks, the heat rises
within the stove, which is necessary for
complete combustion to take place (greater
efficiency and lower emissions).
Exactly what’s required where
it’s required !
The air required for combustion is therefore
reduced to the exact amount necessary and
is distributed as follows :
10
> a small amount feeds the base of the
flames (5),
> another quantity enters the combustion
chamber through small holes arranged
between the bricks (6) at the back of the
chamber and inflames the residual gases
in the upper part of the stove ; this is postcombustion,
> a final quantity sweeps the glass (7) to
prevent smoke from condensing there.
This air is also used in post-combustion.
2 air circuits
1. The air required for combustion can be
drawn directly from outside using a duct (2).
Benefits :
> the outside air does not lower the house
temperature before entering the stove,
> there is no risk of backdraught (nor CO
intoxication) as the stove itself draws the
air required from outside without rarefying
the air inside,
> the operation of the stove is not affectedby
another system that consumes air such as a
kitchen hood or air conditioning …
2. The room air heats up while circulating in a
double wall around the stove. This circuit is
completely separate from the combustion
circuit. The room air is drawn from around
the stove or from further away if the stove
has a fan. It escapes from the front part
of the stove. If the stove is a fitted model
(Stûv 16-in), outlet ducts can be connected, for example, to divert hot air into an
adjacent room.

With or without a fan ?
Without a fan
With a fan
The Stûv 16, in contrast to previous inserts,
has been designed to operate without a fan.
The fan is optional. The official efficiency
measurements ( see pages 12, 13 and 15 )
have been taken on stoves without a fan.
There is a 6-7% improvement in the efficiency
of the Stûv 16 fitted with a fan according
to tests carried out by the Stûv laboratory.
It can direct significant volumes of air,
keep room temperature constant and even
create a circulation of hot air in an adjacent
room.
Benefits :
> no need for an electrical connection,
> easy to install, particularly with
regard to replacing a previous insert,
> easy to maintain.
The fan fitted in the Stûv 16 is of a large size
so that it can rotate slowly and therefore
quietly, particularly as it is situated under
the stove. It is still accessible from inside the
stove to enable maintenance.

A highly efficient stove
with a retractable door
The principle
The stove with a retractable door is designed
to be fitted.
The glass door slides upwards and is hidden
behind the brickwork. The stove is then like
an open fire or a hearth which enables you to
grill food !
With the glass door lowered, it produces
excellent efficiency and ensures complete
safety. Its exceptionally large glass door
provides a perfect view of the fire.

Fonctionnement
Efficiency and performance
The Stûv 21 makes use of a simple law of physics – natural convection : the air circulates in
a double wall (1) around the stove, heats up,
rises and escapes through purpose-built
vents (2). Some of the hot air can be directed
to an adjacent room.
All of the Stûv 21 models achieved excellent
results in tests carried out according to
European standards. See page 30.
A fan is therefore not required with the basic
configuration. The air required for combus­
tion sweeps the inside of the glass door (3)
preven­ting the deposit of soot so that it
remains clean.

Stûv has invented accessible runners, a base where the stove’s opening is flush with the floor, and a glass door without a metal surround on the bottom edge …
Good reasons to choose a
StÛv 21
A very fine line
A metallic surround of just 4 cm runs around
the stove. Its appearance never changes –
neither the runner nor any other device is
visible, even when the glass door is up.
This subtle stylishness means the Stûv 21
blends in perfectly with any interior design.
departing from the traditional vertical design.
The opening of the stove may extend to the
floor provided sufficient depth is left to fit the
base of the stove (2). It can also be installed
into an old fireplace.
Some manufacturers do not provide easy
access to these components, which can sooner
or later result in major inconvenience (disassembly of the fireplace in the event of problems, and a bill for lots of hours worked).
Design that benefits the user
With Stûv, all mechanical components are
housed within the framework of the door and
are accessible in a matter of seconds as the
photo above illustrates (4).
The patent registered for this system concerns
the tilting door, which houses the glass door
raising mechanism (3). Partial raising of the glass door (1)
The Stûv 21 is designed to work with the
glass door closed or with it in the intermediate position. The intermediate position aims
to provide an open fire while limiting the risk
of backdraughts. In this position, no runners
block your view of the fire.
Integration into a low space
Partial raising of the glass door also allows
the Stûv 21 to be integrated into a low horizontal space. Limiting the travel of the glass
door means the height of the stove can be
reduced by 15 to 25 cm depending on the
model, allowing the stove to be integrated
into a low horizontal space and therefore
This design enables easy maintenance : the
door tilts forward to allow the inside of the
glass to be cleaned. All parts of the system
remain accessible. No other system can offer
this patented benefit.
Stûv was the first company to take these
aspects into consideration.
Wall in a heating system ?
Everyone knows that mechanical components such as ball bearings, pulleys, runners
and cables will require maintenance or even
replacement sooner or later, especially when
subjected to high temperatures.

Barbecue
The Stûv 21 enables you to grill food.
See page 41 for more information.
The accessories which
facilitate and improve
the finishes.
The Stûv 21 can be installed without a frame
or decorative accessories. The craftsman who
installs the stove can make full use of his
creativity.
The frames
The use of a frame conceals the thickness of
the wall where the stove is fitted and allows
a minimalist finish around the opening.
The decorative accessories
Decorative accessories enable the horizontal
(SF8) character of the fireplace to be
accentuated.

The facades
The facades completely close the recess - no
need for masonry or rendering work after installation of the stove in the recess. In addition,
the facade means the stove does not have to
be fully inset and reduces the depth of the
recess.
The facade integrates the convection air outlets in many cases. This solution also has the
benefit of maintaining complete accessibility
to the stove and its connection to the smoke
flue.

Glass-door fire, open fire
and slow burner - 3 in 1 !
Révolution !
Changing from one operation mode to another in all models of the 30 range, simply
involves selecting the appropriate door at the
stove’s opening by rotating the drum.
This takes just a few seconds.
> In glass-door mode, you can enjoy a
wonderful view of the flames in complete
safety with excellent efficiency. This ensures
economical and environmentally friendly
operation.
> In open fire mode, you can hear the
crackling of the fire, enjoy the aroma
of an open fire and also have a barbecue !
40
> In slow-burner mode, a solid door with
increased airtightness allows slow burning
throughout the night. The solid door hides
the combustion chamber when the stove
is not in use.
Barbecue
The barbecues designed for the Stûv 21,
Stûv 30, Stûv 30-up, Stûv 30-compact and
Stûv 30-in offer a com­pletely different
approach to cooking. The food is placed in
front of the flames as opposed to over the
embers.
A healthier and faster method of cooking
There is no need to wait for glowing embers,
just push the embers and flaming logs to the
back of the stove.
The food is placed vertically in front of the
flames without coming into contact with
them. The heat cooks the food and the fat
that runs off does not re-ignite the flames
as with horizontal grills.
By adjusting the intensity of the fire, you can
quickly cook red meat or alternatively use a
slow-cooking method
Easy to use
The grill can be fitted to the stove in a matter
of seconds (even when in use). A stainless
steel drip tray collects the fat and juices,
allowing the food to be turned over without
dripping into the stove or onto the floor.
Odours do not spread through the house,
they vanish up the chimney.
The barbecue kit comes in a variety of forms for the different models in the Stûv range. Here it is installed
on a Stûv 30-in. Photo : François Goffin
Unlike traditional barbecues, fat does not drip onto
the embers. There is no blaze-up that burns the
food.
41
Stûv 30-compact
Developed to meet the growing demands of
energy-efficient or smaller homes, these compact stoves succeed magnificently in combining performance with design.
Why?
Most stoves currently available on the market
are too powerful to install in energy-efficient,
better insulated homes. As a result, these
high-output stoves are not used optimally operating them at a lower rate reduces their
efficiency and makes combustion less clean.
Outstanding performance
If used optimally, these new stoves achieve
efficiency of over 80%. In order to achieve
these results, Stûv has introduced some innovations which make all the difference:
> the smaller combustion chamber enables
a temperature to be maintained which is
conducive to clean combustion.
> he combustion chamber has a double-combustion system, which enables cleaner and
more efficient combustion..
> 3 modes : Glass-door fire, open fire and slow
burner ! See p 40.

The benefits
Combustion air
As energy-efficient homes are more air-tight,
Stûv has designed these new stoves to draw
air for combustion from outside the room.
This system has various benefits :
> no cold draught in the room,
> the stove does not rarefy ambient air.
Clean-glass system
The air for post-combustion sweeps the glass,
keeping it clear and clean.
The tall configuration
This model includes a heat recuperation
system located above the combustion chamber and also has increased efficiency.
Barbecue kit ...
... allows you to enjoy barbecues, even in
winter! Unlike traditional barbecues, fat does
not drip onto the embers, so there is no
blaze-up that burns the food.

Operation
> Sophisticated post-combustion system.
> an articulated diverter (1) which encourages draught
to avoid backdraught when the door is opened to reload
the stove, or when the stove is being used
in open-fire mode.
> The smoke flue is integrated into a convection column. The
air circulating in the double wall collects the heat dissipated
by the smoke flue and distributes it in the room. The wall is
protected from radiation. This visible flue supplied with the
stove is attached to the ceiling (up to 2.90 m) and can be
adjusted according to height.
> The connection to the chimney can be made above (2) or
behind (3).
> An outside air inlet for combustion can be connected
directly to the stove to avoid using room air. This prevents
draughts and the possibility of the stove being affected by
other systems using air (cooker hood, ventilation system).
This ensures comfort and additional safety. The air is
drawn from the ground (cellar or ventilated empty space)
or from the back. The duct is protected by a cover with
the same cross section as the convection column.
> A single set of controls (4) automatically manages the
distribution of air between combustion (5), post-combustion (6) and sweeping of the glass door (7).

The Stûv best suited to your home
The stove
On the other hand, greater power would be required for a second
home, which would have to be heated up quickly at the beginning
of the weekend.
It is important to choose the stove with the heating power best suited
to the space to be heated. It is a matter of determining which stove
will be lit as often as possible, making it the most economical and most
environmentally friendly.
A stove that is too small will not be able to heat up (or reheat) the
room in cold weather. Alternatively, a stove that is too powerful will
often work at a low rate in conditions that are not very beneficial.
Sometimes it will overheat the room even at a lower rate. Choosing a
20 kW stove where a 10 kW model would be sufficient would be a
very bad decision.
How to determine the power required ?
The power of a stove is expressed in kW and indicates the amount of
useful heat (i.e. heat which actually heats the house) that this stove can
produce.
This heat must effectively compensate, as closely as possible, for the
heat that the building naturally loses. The power required to heat a
room varies depending on outside temperature, the size of the room,
which way the property faces, geographical location and the standard
of insulation in the building …
These various factors mean it is not easy to carry out a simple calculation. The best way to make sure you choose the Stûv best suited to
your requirements is to consult your supplier. He will be able to assess
your needs on site. Explain how you intend to use your stove and he
will be able to advise you in your choice.
The type of occupation also has to be taken into account. In a house
where there is central heating, you would install a less powerful stove
that would regularly operate at its optimal rate and which would be
sufficient except in winter, with the central heating only being additionally used in cold weather.
48
The efficiency
The smoke
The stove’s efficiency indicates the percentage of heat produced by the
combustion of the wood which is actually used to heat up your house :
A stove with 80 % efficiency releases 80% of the energy from the wood
for heating the house. Did you know that an open fire, for example,
rarely has efficiency greater than 10%, which means that 90 % of the
energy consumed goes into the atmosphere ?
It contains heat and various gases including CO2, CO and fine particles
that affect the respiratory passages. With high-performance stoves that
are used correctly, these emissions are very limited, but they increase as
soon as the efficiency falls and combustion is less complete.
To sum up, a stove well suited to the room to be heated works most
frequently at its optimal rate and therefore produces good combustion
and high efficiency. This means that consumption is minimal and
emissions into the atmosphere are greatly reduced.
It is important to understand that the efficiency drops when the stove
operates at a lower rate and that combustion is less complete.
Providing a point of comparison
This is why public authorities, who are committed to fighting global
warming, are encouraging the replacement of older low-performance
stoves with highly efficient ones.
Stûv stoves are officially tested according to the European standards
EN 13229 (for inserts) and EN 13240 (for stoves), which provide a
safety guarantee for people and property. As well as checking safety,
the laboratories measure power and efficiency and analyse the smoke,
enabling consumers and professionals to make valuable comparisons of
products.
49
Conditions for proper functioning
The chimney
And what is needed to create this draught ?
The chimney – or its draught to be more precise – is the most important
factor in ensuring your stove works well. The smoke produced by the
combustion of the wood – very hot and therefore very light – has a natural propensity to rise. The flue must allow it to disperse.
> sufficient height,
> a chimney that is as vertical and straight as possible,
> a smooth surface that does not prevent the dispersal of smoke,
> an appropriate size in cross section – preferably round rather than
square – and never less than the diameter of the stove’s smoke outlet,
> a thermally insulated flue : if the smoke cools down, it loses its
upward momentum, which may result in condensation. Flues which
cross parts of the building that are not heated (attics) or flues installed
outside must be insulated,
> a chimney that has a good cover, which ensures a sufficient draught
regardless of the direction and speed of the wind.
What makes a good chimney ?
It must create sufficient but not excessive draught for the stove to
which it is connected.
The dimensions of the chimney are determined by your supplier.
However, you can get an indication by visiting : www.stuv.com > Questions-answers > Which chimney for your Stûv ? Or which Stûv for your
chimney ? Whatever the answer, let your supplier to confirm it.
50
air
Your supplier : a key partner in your project
The combustion of wood consumes air (8 m³ of air is required to burn
1 kg of wood). In older houses, air gets in under the doors and frames.
In modern houses, which are more airtight, an outside air inlet is required. This should be as close to the stove as possible.
To obtain an accurate analysis of your chimney, to get advice on the
Stûv best suited to your house or to find out about original integration
solutions or possible offers or fiscal incentives available in particular
European countries or regions, your supplier, who has lots of experience,
should be consulted as early as possible in your construction or renovation project.
Other systems that require a lot of air – such as a cooker hood or ventilation system – which can affect the operation of the stove, must also
be taken into account. These could affect the operation of the stove
with the risk of the fire going out or backdraughts of smoke into the
house. Point these considerations out to your supplier when choosing
your stove. He will help you choose the best solution.

Which wood
should you choose ?
Good wood !
Drying
Different types of wood have different heat capacities and do not burn
in the same way. Generally speaking, you should choose hard wood
such as oak, beech, ash, hornbeam or fruit trees. They produce lovely
flames and lots of embers, which glow for a long time.
Whatever wood you choose, it should be really dry. Damp wood provides a great deal less heat and a large amount of the energy is used
just to evaporate the water it contains. Sapwood – as the soft wood just
beneath the bark is called – can contain up to 75 % water. Moist wood
also releases a lot of smoke, produces few flames and causes the stove,
its glass door and the chimney to get dirty and soot up. Big logs should
be chopped up to dry better. Wood should be covered or sheltered
from the rain but well ventilated. Generally speaking, you should allow
two years for the wood to dry properly. You will soon learn to estimate
the dryness of the logs by holding them in your hand. The drier they
are, the lighter they will feel and they will produce a clearer sound
when you knock them together.
Unsuitable
Wood that has been treated with chemicals, railway sleepers or chipboard quickly dirties the appliance, soots up the chimney and produces
toxic fumes.
52
1
Beech (1) and ash
Hornbeam (3), cherry wood (4), fruit trees
Firewood to be recommended : they dry quickly and are readily available. They should be stored under shelter as soon as they have been cut
or split, otherwise they rot very quickly and lose their heat capacity.
They are easy to ignite, provide good fires and bright flames.
Excellent fuels but scarce. These are hard woods
providing lovely steady flames, and give good
embers. They are ideal for a barbecue and for
slow burning.
Oak (2)
Birch (5), lime, chestnut, poplar,
robinia, acacia
An excellent fuel, but as opposed to other wood, must remain unsheltered for two years so that the rain can wash away the tannins it contains.
Then it should be stored under shelter for another year or two before
being suitable for burning. There is a significant proportion of sapwood
(which burns too quickly) in small branches. Oak burns slowly, provides
a steady fire and gives lovely embers. It is ideal for a barbecue and for
slow burning.
These are broad-leaved trees producing soft wood.
They provide nice, lively flames and few embers.
This wood burns fast and can be used to light or
rekindle the fire. Warning : poplar produces abundant and volatile embers. Robinia and acacia can
cause embers to spit.

Conifers
They produce a lot of heat but burn quickly ;
they spit embers and the resins they contain dirty the

The company
In 1983, Stûv was made up of just two men, Gérard Pitance and Benoît Lafontaine, who decided to join forces to develop
and produce an exceptional wood stove – the current Stûv 60 – was designed by Gérard Pitance (professional designer).
They subcontracted the production of the components and focused on assembly and installation.
The history
Gérard Pitance
Their capital was creativity and motivation
Today
Start-ups take time, but the company gradually developed,
acquiring equipment along the way, increasing its workforce
and constantly creating new stove designs.
Stûv employs 120 people, pro­duces 15 000 stoves a year and exports
70% of its production throughout Europe.
In 2006, the company set up the production of stoves in a new
5 000 m2 unit at its site in Bois-de-Villers, near Namur in Belgium.
The components are manufactured by subcontractors using state-ofthe-art equipment, mainly in Belgium. Assembly, painting, adjustments
and quality control are carried out at Bois-de-Villers.
In 2008, a new 3 000 m2 extension in Floreffe became the home of
the Research & Development department, the workshop for creating
pro­totypes and the production of cladding.
54
A classic design
Focussing on people
The design of Stûv stoves is not like the rather flashy styles often found
in magazines. Stûv designs are subtle, to ensure they can be sustainably
integrated into customer’s homes.
The customer is entitled to correct information and a high-quality
product. But so too are the engineers who install the stoves and keep
them in the best condition.
The environment
And, of course, the staff who manufacture the stoves in our
workshops …
Stûv has always produced high-performance stoves, which means
transforming as much energy from the combustion of wood into heat
as possible. It’s a matter of economy. But it’s also a question of ecology,
because these stoves emit less heat and smoke into the atmosphere.
Today, all Stûv stoves have been tested in accordance with European
standards, but our technical staff still work relentlessly to achieve even
greater improvements in the efficiency of the stoves to reduce emissions and to create products that can be intelligently integrated into
the homes of the futur.
