Many manufacturers changed to natural gas in making their products
but are now switching back to coal because it is less expensive.
Coal burns super hot and needs a very thick
firebox - like ours- to withstand the intense heat.
The Shaver Coal Burning Furnace is specifically designed to
burn coal and it comes with a shaker grate to help get rid of clinkers.
However, COAL AND WOOD can be burned separately or

Our shaker grate is the FIRST adjustable shaker grate
in the industry!
You can adjust the spacing from ½" to 1" to accommodate different types
We now carry
4 sizes of
COAL burning furnaces.
These models are specifically designed to burn coal. With the
fan feeding oxygen in from the bottom, the coal burns easily. Simply but a wood furnace model (above) and add an
optional shaker grate to help get rid of the clinkers.

Grades of Coal
Anthracite – this type of coal
has the highest percentage of fixed carbon and a lower
percentage of volatile material than all other coals, making
it harder to ignite. However, when it is ignited, it burns
The most well-known anthracite mines in the United States are
in western Pennsylvania.
Bituminous – Bituminous coal is
the most abundant and most widely used coal. This is the type
of coal found in the Appalachian region. It has a higher
heating potential and is used for making coke. It has a higher
percentage of fixed carbon, greater heat value and better
weathering characteristics than lignite and sub-lignite coals.
Most of the non-metallurgical grades of bituminous coal are
burned in boilers or furnaces to obtain thermal energy for
generating electricity. Because bituminous coal is softer than
anthracite, it is often referred to as soft coal. It does
emit smoke as it burns, unlike anthracite.
However, there is a region in Southern West Virginia where the
bituminous coal burns relatively smokeless. The
Smokeless Coal Fields of Southern West Virginia are unique in
Sub-bituminous – A lesser grade
of coal, it has more moisture and less carbon than bituminous.
Nut Coal - Very small coal - about 1/4" in size. See
important note below.

Pea or stoker coal
must notify us, if you plan on using "NUT COAL", rice
coal or pea coal, as they are all very small.
You cannot burn
"run of the mine" coal, without voiding the warranty
because it burns way too hot.
In the United States, the coal power plants
generate 50% of the electricity produced.
Lower your utility bills! Coal is
easy to load - by the shovel load, as opposed to wood. You can eliminate
your gas, electric or oil bill simply by using a Shaver Outdoor
Furnace to heat your home and hot water. Coal is very
plentiful in many Eastern states.
Heating with coal - outside of the
house - is CLEANER! No more smoke, ashes, bark, bugs, log piles and trash in the house. Many
types of coal burn virtually smokeless.
Heat your hot water with your Shaver
Furnace and save $30-60 a month on this
feature alone! It takes care of all your hot water needs and
the elements in your hot water heater may never come on
Safety. Our furnace is made to
be situated away from the house, in the yard. The usual
distance is about 50 to100 feet. Outdoor coal furnaces remove the
danger of wood stove fires in the house. Any fire
department that compares the safety of indoor units versus
outdoor furnaces will clearly state that outdoor furnaces are
the winners. This safety feature usually lowers your insurance rates.
With ZERO wires, electronics, fans and controls on the outside of our
furnaces, our unit is simpler and safer.
One furnace can heat multiple
buildings; so there is no need to purchase a heat source
for each. Simply run an extra run of PEX pipe to the area you want
to heat - even garages, shops and greenhouses without an existing furnace!
Some people even heat their driveways!
Residential and commercial buildings,
factories, restaurants and garages can all be heated easily
with our coal furnace.
Simple, clean and efficient, one unit can heat your house or/and
shop, garage, swimming pool, hot tub, greenhouse or factory.*
