Many manufacturers changed to natural gas in making their
products but are now switching back to coal because it is
Coal burns super hot and needs a
very thick firebox - like ours; one of the few that can 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 simultaneously.

A video of how the shaker grates work.
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 of coal.
We carry 4 sizes of
COAL boilers. These models are specifically designed to burn
but can burn wood too.
With the fan feeding oxygen in from the bottom, the coal burns
easily. Shaker grates are installed in all models 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 relatively
The most well-known anthracite
mines in the United States are in western
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 the
Sub-bituminous – A
lesser grade of coal, it has more moisture and
less carbon than bituminous.

You cannot burn "run of the mine" coal, without voiding
the warranty because it burns way too hot.

power plants generate 50% of the electricity produced.
Lower your utility

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
so there is no need to purchase a heat source for
each. Simply run an extra run of PEX pipe to the area

without an existing furnace! Some people even heat
commercial buildings, factories, restaurants and
