When a new charge of wood pellets are augered into the firebox, the first stage of combustion begins again.
The charcoal heats the fresh wood until it gets hot enough to react and ignite, and the process continues. All
four stages can take place concurrently but complete combustion requires proper placement of secondary air
and adequate temperatures. This is incorporated in the design of the Heatmor furnace.
Efficiency Measurements
There are different ways of expressing efficiency 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 bonfire; 100 pounds of wood burns and produces three pounds of ash, which equals 97
percent combustion efficiency. Good combustion efficiency but poor heating efficiency. 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 efficiencies. Ninety percent combustion efficiency times 60
percent heating efficiency results in a 54 percent net efficiency.
Handling and Storage of Wood Pellets
Common questions concerning wood pellet storage.
1)
Q. Do I have to keep my wood pellets covered?
a
. Yes, it can be more convenient. It is an extra task if snow has to be knocked off the bags
before they are brought to the furnace for opening and pouring into the hopper. It will also
prevent rain and snow landing on the any exposed wood pellet bags that could add a
certain amount of moisture to the wood pellets. Refer to “first stage of the burning process.”
2)
Q. Why is it important to have my loading of wood pellets directly at the furnace when I
go to load my furnace?
a.
Because it is best to always keep a tight seal on the hopper door to prevent any possibilities
of burn back.
3)
Q. Is it a good idea to put the front of my HEATMOR™ into my wood storage building so I
can load the HEATMOR™ from inside?
a.
This is never a good idea. The HEATMOR™, is designed to be placed
outside away from
all
buildings
to maintain optimum safety. Refer to the “Clearance to Combustibles” section.
