The powerful presence and warmth of a fire in our homes offers us a unique sensory and aesthetically pleasing experience. What’s more, a wood-burning heating system is the most cost effective heating option and the initial outlay can be recovered in a very short space of time.

BREATHING HOMES

Comfort, health and the environment are now inseparable

Protecting our health and respect for our environment are no longer optional. For this reason, LACUNZA designs and manufactures products with the wellbeing of your home, your family and your environment in mind.

All our stoves and fireplaces are wood burning. Compared to fossil-sourced energy, wood is a natural fuel that is economical and environmentally friendly, given that it is a renewable and sustainable source of energy.

Glossary
A-L M-Q R-Z
A
AEFECC
AEFECC is the only association that brings together manufacturers, importers and suppliers of wood burning stoves, fireplaces, cook stoves, boilers and, in general, wood burning and biomass appliances in Spain.
Airtight
Combustion occurs within a closed chamber, acquiring the necessary oxygen from the outside without altering the oxygen in the fireplace.
Atmospheric power
Heat transferred to the atmosphere.
Axial fan
This is a type of fan where both the motor and the blades are mounted directly on the shaft. When the shaft and blades rotate, it produces a current parallel to the shaft.
C
CE Power
Average power available from the device, certified in official laboratories.
Centrifugal Turbine
A centrifugal tangential fan in which air is driven by a turbine or impeller, sucking it through the centre, expelling it through its blades parallel to its axis and exiting in a perpendicular direction to achieve greater pressure / speed with less sound.
Cleaning Access
Easy access to remove soot through a hatch (patented) Easy manual disassembly of the baffles, no tools required.
Cleanout door
They are usually cast doors without glass. They are totally opaque.
Closed stove
Completed constructed modular wood burning cook stove ready for installation.
CO emissions

A value that measures emissions of carbon monoxide, an odourless, colourless, tasteless, toxic and highly flammable gas.

Conto Térmico
An Italian regulation that encourages interventions to increase energy efficiency and thermal energy production from renewable sources for small installations.
Convection
It is called convection when heat is transmitted and creates natural air circulation in any room.
D
Damper
Rotating cover that allows the passage of air/smoke through a pipe to be opened/closed
Deflector
A device used to divert the direction of the smoke flow before leaving the duct
Double Combustion
Technology whereby the gas from the firewood’s initial combustion is burned again. It provides greater efficiency and life for your firewood with lower consumption.
Double sided
These are fireplaces or wood burning stoves that have glass on the front and back of the fireplace in order to see the fire and get heat from both sides.
Ducting
Channelling of air through ducts
E
Easy Fire Control
Fire control system that can regulate the optimal combustion and cleaning of the firewood appliance with one simple remote control device.
Easy To Clean
Surface treatment of the wood burning cook stoves with a high-quality enamel. Makes cleaning easy with as little as a damp cloth.
Ecodesign 2022
A European regulation (compliance with which is mandatory starting in 2022) that will require greater energy efficiency in all products and lower emissions of CO, OGC, NOx and other types of hitherto uncontrolled pollutant gases.
Ecolabel

A European certification related to energy consumption. It grades the product based on strict sustainable criteria defined at European level and ensures that the purchased product meets the maximum sustainability requirements

Energy efficiency
This consists in the efficient use of energy. We refer to an efficient wood burning appliance when it consumes less energy than the average energy required to make it work.
Eolo System
High pressure ventilation system with centrifugal turbines and speed regulator (switchboard) to allow different rooms of the home to be heated through ducts.
External Air Inlet
Connectible system that takes air from outside the house for combustion. Suitable for low consumption housing.
Extra Clean Glass
Novel air intake system on the glass to keep it clean for longer.
F
Fan

An instrument or apparatus with rotating blades that drives or removes air.

Flamme Verte
Flamme Verte is a quality label for wood burning appliances in France. To obtain the Flamme Verte label, the energy and environmental performance of each device is controlled in laboratories, accredited against ISO / IEC 17025 and notified by the European Commission, whose tests give access to the CE certification.
Flow Driving
Hot air bypass system with selectable outlet. It allows for longer ducts and makes it possible to close the air outlet. Includes a turbine control unit.
G
Guillotine opening
A sliding door opening that pulls up and can stay hidden
H
Hatch
Entrance that provides access to clean the cook stove, wood burning stove or fireplace.
Heat ducting
Wood burning appliances with heat ducting are those that heat the room in which they are installed and also the adjoining rooms through a duct system that distributes the heat to different spaces.
Heatable area

The square metres heated by the wood burning stove, cook stove or fireplace.

Heatable volume

The cubic metres heated by the wood burning stove, cook stove or fireplace.

Heater
Cook stoves, wood burning stoves or fireplaces that heat water in a circuit to heat the entire house in a more even and balanced way
I
Inset
Also known as cassette fireplaces, they are an evolution of the classic open fireplace. Specially designed to be inserted into existing holes
Ironwork
Set of iron pieces used to decorate or reinforce the structure of a door or another object.
M
Monobloc
An appliance, in this case for firewood, that is embedded in the wall in a single piece.
N
Nozzle
Tubular opening where the air used for combustion in the wood-burning appliance enters in or travels out through ducts to other rooms
P
Perfect Combustion
Optimum burning technology allowing high combustion efficiency values to be achieved. Consumes less and makes loads of firewood last longer.
Potentiometer
Device with which the wood burning appliance’s power can be controlled.
Power range

Minimum and maximum power of the wood burning appliance or the variance in power obtained from conditions of slow and maximum combustion.

R
Refractory

This refers to some materials’ property of being resistant to high temperatures without decomposing or storing heat.
