value is expressed in calories (or kilocalories) per unit of weight of fuel.
Oxidiser:
chemical substance that feeds combustion (essentially oxygen) and is
essential for it to take place.
Pa (Pascal):
standard IS unit of pressure and tension. This unit is named after Blaise
Pascal, eminent French mathematician, physicist and philosopher.
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.
Plumb:
vertically above the installation.
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.
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.
Rated power:
Electric power consumed by an energy source. Measured in watts.
W (Watt):
IS unit of power.
