Outside Wood Heater - How It Works
The drum in a high capacity cylindrical firebox.
On the upper portion of the door is the adjustable draft control disk,
for the regulation of air entering the unit. The air is preheated
as it is dawn down the internal draft channel on the inside of the door.
The draft is sucked into the bottom of the heater with a turbulent
action, mixing with the wood gases for efficient combustion.
The patented design of the air-tight door and the matching door frame
and the internal draft channel make the unit spark proof.
16 gauge steel walls of the dram heater are strong enough to withstand
constant high temperatures, and yet generate quick heat. It takes heat
longer to travel through heavy-walled material. And the more heat
that penetrates the surface, the less hot air escapes up the chimney.
This stove , therefore, allows the maximum amount of heat to penetrate
into your home.
Being round gives the barrel more resistance to stress. In the
heavy, flat sided rectangular stoves, the corners get hotter. In
the round thinner walled stoves, the temperatures of the wall is more
uniform, therefore, the thermal stresses are less. And, since
steel is flexible, it has the ability to bend under stress, while cast
iron can only crack when it reaches extreme temperatures.
No Grates, Please
Hot coals last longer in stoves without grates. Ashes which the
coals lie in keep oxygen from reaching much of the charcoal surface and
thus reduces the rate of combustion. The ashes also thermally
insulate the coals, slowing the cooling rate.
Without a grate, large volumes of ash are allowed to accumulate and not
effect the stove's operation. Compaction is also possible when
wood lies directly on the ashes. The heat from a direct fire can
fuse the ash into a semi-solid crust, thus allowing more ash to be
stored in the same volume of space.
Duct Work
The unit is designed to operate with only one heating duct coming
through a wall or window. Existing ductwork is not designed for
wood heat. And will not effectively move the heat around your home
because of static pressure. It is also not safe because existing
ductwork is not insulated and sits up next to your floor studs. If
you have a power failure, existing ductwork could possibly become
overheated causing a fire.
Just One Heat Register
Through the one register your Lil' House Heater will supply your home
with 465 cubic foot per minute of air heated to above 120 degrees.
Used in conjunction with a cold air return supply air from the far side
of your home you are actually moving 930 cubic foot per minute of your
home's own air. As the duct pushes the heat in, the cold air
return pulls air out; thus moving the heat through your home
efficiently.
May I Burn Coal In My Wood Heater?
Definitely, NO!!! This is a wood burner only. The use of
coal requires grates and a large volume of oxygen for proper combustion.
Our unit is designed to provide a controlled small amount of oxygen
required for wood burning.
