* A 70% efficiency rate means that 70% of the energy contained in the firewood is
used to warm your home or, in other words, you are able to produce the same amount
of energy with much less firewood.
* A Solzaima 5kW insert with an efficiency rate of 75%, will consume approximately
3,5 pounds (1,6 kg) of firewood per hour to warm a 389 sq. ft room (35 m2).
* Typically, a traditional fireplace has an efficiency rate of approximately 10%, which
means it will consume about 26,5 pounds (12 kg) of firewood to produce the same
5kw necessary to warm the same 389 sq. ft room (35 m2).
6.4. Additional combustion air intakes and outtakes
6.4.1. Air intake for combustion
* The cold air intake can be carried out from below the unit, with the exception of the
Back Box Eco and Back Box Slim Eco units, so the unit will draw cold air from the room
where it is installed, see Figure 12.
A traditional fireplace with an efficiency rate of
10% consumes 26,5 pounds (12 kg) of firewood
A fireplace equipped with a simple fire and
providing an efficiency rate of 30% consumes 8,8
pounds (4 kg) of firewood
A fire with an efficiency rate of 50% consumes 5,3
pounds (2,4 kg) of firewood
A Solzaima fire with an efficiency rate of 75%
consumes only 3,5 pounds (1,6 kg) of firewood
