Glossary
*
Ampere (A):
SI unit of measurement of electric current
*
bar
: unit of pressure equal to exactly 100,000 Pa. This pressure is very close to
standard atmospheric pressure.
*
cal
(calorie): equal to the amount of heat required to increase the temperature of one
gram of water by one degree centigrade.
* Groove:
housing for the sealing ring.
*
cm
(centimetres): unit of measurement.
*
CO
(carbon monoxide): Lightly flammable, colourless, odourless and very dangerous
gas, due to its toxicity.
*
CO
2
(carbon dioxide): Gas needed by plants on the one hand for photosynthesis, and
emitted into the atmosphere on the other, contributing to the greenhouse effect.
*
Combustion
:
a process that releases energy. Combustion is basically a chemical
reaction that requires three things in order to take place: fuel, oxidant and ignition
temperature.
*
Oxidant
: chemical substance that feeds combustion (essentially oxygen) and is
essential for it to take place.
*
Fuel
: anything that can undergo combustion, in this case wood.
*
Creosote
: chemical compound created by combustion. This compound is sometimes
deposited on the glass and flue of an insert fire.
*
Circuit breaker
:
Electromechanical device that protects a given electrical appliance.
*
Energy Efficiency
: capacity to generate large quantities of heat with the least amount
of energy possible, causing the least environmental impact and reducing the energy
budget.
*
CO Emissions
: emission of carbon monoxide gas into the atmosphere.
*
CO Emissions (13% O
2
)
: carbon monoxide content corrected for 13% of O
2
.
*
Differential Switch
:
protects people and property against earthing failures, preventing
electric shocks and fires.
