Efficiency Measurements and Types of Fires
There are different ways of expressing efciency and to correctly compare values.
Combustion Efficiency - Input Based
The amount of fuel that is completely burned compared to the total amount available for combustion expressed
as a percentage.
For example:
An open bonre; 100 pounds of wood burns and produces three pounds of ash, which equals 97
percent combustion efciency. Good combustion efciency but poor heating efciency. No heat got into
the house.
Heating Efficiency - Output Based
The percentage of the heat produced that was actually absorbed into the water and transferred into the house
from the Heatmor
TM
.
Net Efficiency
This is the product of the combustion and heating efciencies. Ninety percent combustion efciency times 60
percent heating efciency results in a 54 percent net efciency.
Loading Of The Furnace
Loading the furnace relative to the heat load will result in more efcient performance. More nearly matching
your fuel load to the current temperature conditions for an 8 to 12 hour burn will result in longer burn cycles,
higher overall burn temperatures and more efcient performance. Your furnace has been rated for an 8 hour
burn cycle. Burning wood with less than 30% moisture content will also result in better efciency.
