* Rated output: Electric power consumed by an energy source. Measured in watts.
* Nominal heat output: heating capacity, e.g., 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.
* Efficiency: 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.
* Heat-resistant: resistant to high temperatures and thermal shock.
* Ceramic glass: Highly resistant ceramic material produced through controlled
crystallisation of vitreous materials. Used widely in industrial applications.
* W (Watt): SI unit of power.
