The fireplace was the heart of the 

home 

for three-year-old Juhani Lehikoinen, the 

future founder of NunnaUuni. Today, many 

owners of NunnaUuni fireplaces agree with 

Juhani on this. The picture shows young 

Juhani heating the home. 

More and more people admit that they long for a simple, earnest, and stable life. 

We value having a home and traditions, and we invest in our environment and 

in time spent with family and friends. We are returning to our roots, and to good 

experiences. 

With Finnish tradition and modern skill, NunnaUuni fireplaces contribute to 

good everyday living. A blazing fire gathers families together and keeps us warm in 

every type of weather. Each time we light the fire, we can have a moment of quiet. 

At their best, those moments create memories that become stories to remember. 

A fire strengthens the flow of positive energy in the home. Soapstone represents 

similar stability and continuity. The stories nature has written in the stone sweep 

us along on a shared journey. 

Heating with wood signifies caring. It involves many ecological and traditional 

values that are passed on to the next generation. Clean and dry wood and a heatstoring 

NunnaUuni fireplace manufactured of pure soapstone form a wonderful, 

energy-efficient combination. Thanks to modern technology, NunnaUuni fireplaces 

burn wood efficiently and cleanly. A choice that is good for the environment is 

good for the conscience, too. 

We have harnessed fire as a faithful servant for you. With warm recommendations.

A gift from one generation 

to the next 

Fire has provided people with warmth 

throughout the ages. That heat is still 

needed today, and this is no cause 

for a guilty conscience. By burning 

wood in a modern, cleanly burning 

fireplace, we contribute to keeping 

the planet in good living condition 

for future generations. 

Wood-heating on the upswing again 

In 2008, a great increase in the use 

of renewable energy sources was entered 

as one goal for the new climate 

agreement by European Union countries. 

In the future, the use of CO2 

neutral wood should increase greatly. 

The agreement supports the research

Joya Angolo Golden 


Carbon monoxide, or coal gas, is produced 

as a result of incomplete burning. 

The Golden Fire gasification burning method has guaranteed 

clean burning in stoves and stoves with baking oven since 1998. 

The challenge in batch combustion of wood has always been the over-gasification 

of the wood and the difficulty in finding the correct ratio for secondary air and gases 

released from the wood. NunnaUuni has solved these problems by developing 

the Golden Fire gasification burning method. It is based on careful air control that 

makes the wood gasify and burn at a high and even temperature of 800–1,200 °C. 

The invention has been patented (EP 1008808). 

One invention – many benefits 

EXCELLENT EFFICIENCY 

Even gasification burning of wood produces 

plenty of energy. 

EFFECTIVE HEAT PRODUCTION 

Heat production is intensified by preheated 

secondary air that keeps the 

burning temperature high. 

MINIMAL EMISSIONS 

As the smoke gases released from wood 

burn immediately around and above 

the wood, the amount of emissions 

remains low. 

QUICK BURNING OF THE EMBERS 

When the embers burn quickly, energy 

production is intensified and the heating 

time becomes shorter. 

CLEAN SMOKE DUCTS 

Thanks to lighting from below, the hot 

and rapidly moving smoke gases prevent 

tar from accumulating in the smoke 

ducts. 

PRINCIPLE OF OPERATION WITH THE 

GOLDEN FIRE 

1 The primary air is led under the wood, 

2 

through the small holes in the grate, to 

maintain the gasification burning. 

2 The secondary air is also led under the 

grate to around the gasification burning, 

where the air is strongly preheated. The 

preheated air mixes with the wood gases 

around and above the wood, raising the 

burning temperature of the gases to a steady 

800–1,200 ºC. 

3 While under the grate, the primary 

and secondary air flow also cool the grate 

structures.. 

All of this is enabled by fireproof 

Mammutti soapstone that stores 

heat quickly and works seamlessly 

with the fire to provide lasting 

warmth.

Heat tempts one to stay even long after the fire has gone out 

The blaze of a fire has its admirers, 

but the heat of NunnaUuni fireplaces 

speaks to you even long after the 

flames have gone out. The even heat

Warmth comes in different forms. Everyone 

who has a NunnaUuni fireplace 

knows that. A soapstone fireplace releases 

heat as the rays of the sun do. That is 

how pleasant the heat from a NunnaUuni 

fireplace feels on the skin. The heat 

waves warm the surfaces that they hit. 

There is no sense of a draught. Even the 

floors feel pleasantly warm.

Radiated heat, the type of heat borne by 

the rays of the sun, is heat that warms the 

surfaces it hits. This makes even the floors 

feel pleasantly warm. 

By contrast, convective heat is based on air

A genuine soapstone fireplace provides more than 24 hours 

of pleasant warmth after just two hours of heating 

NunnaUuni utilises the excellent thermal 

properties of Mammutti soapstone. 

NunnaUuni fireplaces are made 

entirely of soapstone – from the fire 

chamber to the surface structures. 

The best properties of each stone 

type are utilised and harnessed to 

produce heat in the most efficient 

way possible. 

The use of soapstone of various types is based on geological 

properties and thermal tests 

NunnaUuni has a special resource at its sole disposal: a unique Mammutti soapstone deposit that contains several 

types of soapstone. For each type, an optimal purpose of use has been found on the basis of its mineralogical 

composition and internal structure. The optimal type-specific purpose of use has been determined through geological 

research and verified by thermal tests.* 

We have verified the heatresistance 

of the fine-grained 

Mammutti soapstone type 

selected for the fire chamber 

The heat-resistance of the Mammutti soapstone 

type selected for the hottest part 

of the fire chamber has been measured 

with a thermal shock test (DIN 51068). 

The test scale is 1–30, with the test ceiling 

of 30 indicating that the sample can 

withstand the thermal shock 30 times. A 

thermal shock rating of 28 was attained 

in the test as the heat-resistance measurement 

of the best type of Mammutti 

soapstone.

The great amount of energy produced 

by our Golden Fire gasification burning 

method can be used to heat the 

home highly efficiently. The generous 

amount of thermal energy produced 

by the high temperature is stored in 

the stone already in the fire chamber. 

The soapstone core of the fireplace 

stores up to 70% of the thermal energy, 

while the remaining energy is 

stored in other fireplace structures via 

the smoke ducts. From the core of the 

fireplace, the heat radiates evenly into 

the room. With two hours of heating, 

the slowly released energy can 

heat your home for over 24 hours.

Three benefits in one unit 

A stove with baking oven contributes 

to good everyday life in three ways: 

it produces heat, atmosphere, and 

tasty, healthful oven-cooked food. 

Many of us have seen stoves with a baking 

oven in our grandparents’ houses. 

Now these stoves are appreciated again. 

The development of heating technology 

and new design trends have given new 

forms to traditional models. A modern 

stove with baking oven is the choice of 

young people who appreciate sustainable 

development and energy-efficient 

thinking and also want to have a cosy 

atmosphere with benefits. 

NunnaUuni manufactures two types of 

stove with baking oven: Solo stoves, using 

the heat from the fireplace in the oven 

as well, and Duo stoves, which have 

separate wood-burning spaces for the 

fireplace and the oven.

A stove with baking oven is economical. 

Wood can be used to heat the house and 

cook healthful food at the same time. At a 

low temperature, the food cooks slowly by 

stewing. A clever cook places the ingredients 

in the oven in the morning – to find a 

meal waiting when returning from work. 

The above are examples of grate temperatures 

for Solo and Duo stoves*. Temperatures 

for Duo models are higher, because 

the baking oven itself is also heated with 

wood. The temperatures are for reference 

only, as there are differences between various 

models. 

* Note that at the end of the heating period, the 

thermometer temperature for Duo models is approximately 

50 degrees higher than the temperature above 

the grate. This temperature difference decreases during 

cooling..

living room and kitchen. 

Stove with baking oven or 

wood-burning cooker? 

Those who cook a lot know how solutions 

that make cooking easier can improve 

the quality of life and offer more 

free time – without compromising on 

food quality. 

Stoves with a baking oven are ideal for 

cooking – although they do require some 

planning. Preparing the ingredients is the 

main thing. The oven takes care of the 

cooking, and in the best possible way. 

Even large numbers of pastries can be 

baked with ease. Heating is taken care 

of at the same time. 

Wood-burning cookers are well suited 

to summer cottages, modern kitchens, 

and traditional farmhouse kitchens alike. 

NunnaUuni cookers with a Golden Fire 

grate are probably the only cookers on 

the market that provide clean burning. A 

cooker cooks food and heats the kitchen 

at the same time – qualities appreciated 

especially at summer cottages. A 

cooker releases heat quickly and simultaneously 

stores it within its structures 

for later release.

The Waves of Lake 

Pielinen 

The fireplace in the picture is a bespoke 

model made of massive blocks in 

accordance with the customer’s wishes. 

The lifelike feel of the surface led the 

owners to name the fireplace ‘The Waves 

of Lake Pielinen’. 

Ridge 

This fireplace, built for a villa by Lake 

Saimaa, was influenced by the massive 

open fireplaces in skiing centres in central 

Europe. 

Individual wishes? 

NunnaUuni’s customisation services are there for you. Tell our expert 

what you want from a fireplace – our designer will draw a special 

model for you. Customisation wishes don’t have to be big. Even a 

small change can increase satisfaction. A fireplace can be tailored to 

your wishes with choices of stone, benches, shelves, elevating components, 

or the use of new surface materials alongside the soapstone. 

A modern fireplace 

The owners of this modern stone house 

wanted the fireplace to be made of natural 

stone. This Mammutti soapstone fireplace 

decorated with spectrolite creates a 

pleasant and relaxing atmosphere. 

Major 

NunnaUuni also has ready-made 

customised products for both rustic and 

modern homes. The picture shows the Art- 

Nouveau-style Major fireplace. 

LISTEN TO YOURSELF. AN INDIVIDUAL FIREPLACE MAKES YOUR HOME MORE ATTRACTIVE.

NunnaUuni accessories 

A fireplace with all the bells 

and whistles? 

Besides customisation, a NunnaUuni 

fireplace can be individualised with 

ready-made accessories. Here are a few 

examples. 

Tiles 

Soapstone tiling creates a pleasing look 

around a fireplace. Decorative tiles are 

particularly ideal in front of the fireplace 

(see pictures 1–2 and 4–6). Front tiling 

by separate order. 

Benches and shelves 

Closed or open benches and shelves can 

be integrated into the fireplace (as shown 

in pictures 1–2 and 6). 

Flue connection elements 

If the flue does not reach the floor, the 

flue connection can be made with a separate 

flue connection component (shown 

in picture 5). 

Flue cover stones 

Brick and steel flues can be covered with 

stones, if desired (see picture 4). 

Bottom plinths 

In most pictures in this brochure, the fireplaces 

are placed on bottom plinths (as 

in pictures 3–4). The bottom plinths are 

usually ordered separately, but for Cha, 

Joya, Blanka, and Hestia models, a socle 

is included in the basic price. 

Replacement air under the 

fireplace 

For many NunnaUuni fireplaces, the replacement 

air needed for burning can 

be led under the fireplace. 

Alternative fuels 

Some NunnaUuni fireplaces can also burn 

pellets, with the use of a separate pellet 

unit (Aurum). 

Electrical resistor 

An electrical resistor (1.5 kW or 2 kW) can 

be installed in the smoke ducts of most 

NunnaUuni fireplaces.These resistors are 

especially useful in holiday houses and 

homes that utilise night-rate electricity. 

Ignition damper 

An ignition damper is a plate that can 

be opened to increase the draught in 

the flue and facilitate lighting. Many of 

our fireplaces can be equipped with one. 

Top connection 

Most of our fireplaces are connected to 

the flue from below. Some have the option 

of a connection at the top (as shown 

in picture 2), which is ordered separately.

Heat categorisation helps you choose a suitable fireplace. 

Estimate the heating needs of the building correctly 

Matching the fireplace with your needs 

for heating is important. We recommend 

that you estimate your heating 

needs with the aid of the tables on 

the next page or ask a NunnaUuni 

expert to make an estimate for you. 

We have tested the heating properties 

of our fireplaces, and the models 

are placed in heat categories on the 

basis of the amount of thermal energy 

they store during one heating. 

Reliable testing in a calorimetric room 

NunnaUuni’s Golden Fire fireplaces are tested in a calorimetric room in accordance 

with the SAA 142/222 standard, perhaps Europe’s strictest testing and 

measurement method for heat-storing fireplaces. The test provides more information 

on a heat-storing fireplace than many other tests do, including 

• the amount of thermal energy released by the fireplace 

• the heat-releasing ability of the fireplace and its fluctuation 

• the carbon monoxide, hydrocarbon, nitrogen oxide, and particle content of the 

emissions 

”All of NunnaUuni’s Golden Fire 

fireplaces and Solo stoves with baking 

oven meet all European emission 

and efficiency requirements. More 

information from your distributor.” 

Select the outdoor temperature and 

the size of the room from the table. 

By looking up the amount of heating 

required, you can determine the 

efficiency level (in kWh) of the NunnaUuni 

fireplace you need if you are 

planning to use the fireplace as the 

sole heat source. 

The heat demand of a building is affected 

by, for example, the insulation, 

ventilation, airtightness, internal heat 

production, and surface area of cold 

external walls and windows. A good, 

warm atmosphere is ensured by selecting 

the fireplace that best suits the 

space in terms of its heat production.

Heat insulation meeting the BFS 2002:19 standard

Fireplaces in heat category 3 produce 

more than 60 kWh of thermal energy from 

recommended maximum wood amount in 

24 hours.. 

Fireplaces in heat category 2 produce 40–60 

kWh of thermal energy from recommended 

maximum wood amount in 24 hours. 

Fireplaces in heat category 1 produce 

less than 40 kWh of thermal energy from 

recommended maximum wood amount in 

24 hours. 

The room height in the example houses is 2.5 m, the window 

area is 150f the exterior wall area, and the inside temperature 

is 21 ºC. Ventilation is calculated to be 0.5 times the room 

volume per hour, and the heat recovery efficiency is 50%. It is 

presumed that the heat from the fireplace can move without 

obstruction to the whole area to be heated. Insulation requirements 

vary from country to country. The Swedish heat insulation 

requirements as set forth in BFS 2002:19 are among the 

strictest in Europe. 

Every building is different, so the need for heating energy is 

always space-specific. The diagrams are for guidance only and 

are based on calculations from the values given, but they do 

add security when you are choosing your fireplace. 

You get the most from your fireplace by 

placing it centrally. 

Good quality firewood, a storing 

fireplace of a suitable size and 

place in room that burns wood 

cleanly – that’s all you need for 

heating!

Amount of wood (kg): the maximum amount of wood that can be burned during one heating (according to the user instructions). 

Approximate heating time: the estimated time it takes to burn the given amount of wood. Heating time is affected by wood type, the moisture in the wood, and the draught, 

among other factors. 

Nominal heat output and time: period of even heat release, determined according to the SAA 142/222 testing method (see the diagram).

The SAA 142/222 testing method measures the fireplace’s 

heat release into the room. This is used to determine the 

period of even heat release (the nominal heat output and 

heat release of Leila have been used as an example). 

Thermal energy: the amount of energy received from the amount of wood stated. The amount of thermal energy is affected by wood type and humidity, among other factors. 

Heat storage capacity: times as determined according to the EN 15250 standard. 

100% (h): time from the beginning of heating at which the average between the fireplace surface temperature and ambient temperature is at its peak. 

50% (h): time from the beginning of heating at which the average between the fireplace surface temperature and ambient temperature is half of the maximum value. 

25% (h): time from the beginning of heating at which the average between the fireplace surface temperature and ambient temperature is a quarter of the maximum value. 

According to EN 15250, a fireplace can be called heat-storing when it takes at least four hours for the difference between the fireplace surface temperature and the ambient 

temperature to decrease to 50%.

Ensure a successful 

result 

A successful result is the sum of many 

factors. To get a successful result, 

several technical matters, such as the 

flue, base, and safety distances, must 

be taken care of. There is no need for 

you to become an expert on fireplaces 

– you can always turn to a NunnaUuni 

distributor or a NunnaUuni Master. 

Ordering a home visit is a good way to 

start. You get the service to meet your 

needs, when it suits you. 

Installation included 

Installation of NunnaUuni fireplaces takes 

skill. Therefore, our fireplaces are always 

sold with installation included. The installation 

is fully handled by our partners’ authorised 

installers. NunnaUuni fireplaces 

that are installed by these trained installers 

have a five-year warranty on materials 

and the heat they provide*. 

”Getting a fireplace became easy when I 

passed the responsibility to a NunnaUuni 

distributor. They ensured that the fireplace 

was suitable for the room, acquired the 

necessary permits, took care of the disassembly 

of the old fireplace and the cleaning 

after that, had the new fireplace installed, 

and provided instructions in its use. Things 

were made easy for me as a customer – I 

could just start enjoying the benefits,’ 

explains one satisfied customer.” 

* The five-year guarantee applies to material and thermal 

properties, not metal or wearable parts. 

* Information provided by NunnaUuni. 

** Weight varies by assembly. More detailed weight information can be found on pp. 46–53. 

The properties and benefits of NunnaUuni-fireplace are verified with up-to-date tests and measurements in European research institutes. 

There may be country-specific restrictions regarding deliveries of certain products. NunnaUuni Oy reserves the right to make technical alterations. 

As NunnaUuni fireplaces are manufactured of genuine natural stone, the colour and grain of the final product may differ from that shown in the pictures in the brochure.
