kcal (Kilocalorie): multiple unit of measurement of calories. Equivalent to 1000 calories.
kW (Kilowatt): Unit of measurement equal to 1000 watts.
mm (millimetres): unit of measurement.
mA (milliampere): unit of measurement of electric current.
Pa (Pascal): standard IS unit of pressure and tension. This unit is named after Blaise Pascal,
an eminent French mathematician, physicist and philosopher.
Net Heating Value: also known as specific combustion heat. It represents the amount of heat
released when a certain amount of fuel is completely burned. Net heating value is expressed in
calories (or kilocalories) per unit of weight of fuel.
Rated power: Electrical power consumed from the energy source. Measured in watts.
Rated net heating value: heating capacity, i.e. the heat energy the unit transfers from energy
present in the firewood – measured for a standard load of firewood over a given period of time.
Power output: a manufacturer's recommendation from tests on the equipment with firewood
loads within a reasonable operating range. This power output range will present different
firewood consumptions per hour.
Plumb: vertically above the installation.
Performance: expressed as a percentage of "useful energy" that can be extracted from a given
system, taking into account the "total energy" of the fuel used.
Ignition temperature: temperature above which the fuel can enter into combustion.
Thermoresistant: resistant to high temperatures and thermal shock.
Glass ceramics: highly resistant ceramic material produced through controlled crystallisation of
vitreous materials. Used widely in industry.
W(Watt): IS unit of power.
