We design and build higher
efficiency Rumford style fireplace and the modified versions such as the
Priorfire designed by Chris Prior, the Hart/Rumford by Bob Hart, and
install Bellfires brand pre-cast fireplaces. A
close-clearance Bellfires is available as well.
Rumford style fireplaces are 30-40% efficient,
while a regular box-style fireplace is only 5-10% efficient or less. It just
makes sense to have a Rumford style fireplace in any home.
are some great websites about Count Rumford for more information:
"BOX" style fireplace is only 5-10%
efficient. This is the fireplace style that is
most common among U.S. builders, simply because this
is the style they learned to use early in our U.S.
history and it became the standard. We do not recommend
This design was
created by Count Rumford in the 1700's, and is the
most efficient fireplace and throat design
available. Note that the side walls have been
angled out to allow more heat transfer into the
room. We highly recommend this method for new construction, and to
replace old fireboxes where possible.
We'll be happy to provide an estimate to build
a Rumford style fireplace in your home.
At left is a new Rumford fireplace in the process of being
built by our crew.
Standard buff color firebrick are used, and the surrounding walls are
block, then an exterior brick chimney and interior facial wall will be
Rumford fireplace completed with fireplace surround out of local river
rock that the client collected from a stream on their property.
Four mantels and a raised hearth were included. During a three-day power
outage one winter this fireplace kept their 3,000 sq. foot home warm
enough to stay in.
This fireplace face is 12' tall and 13' wide.
Here is another project that Gene built with his crew- the old fireplace
was removed and new one was built in the Priorfire design. This is
called "Rumfordizing" when an old fireplace is modified.
A Priorfire Rumford fireplace built in an existing chimney - the old
fireplace was removed. Gas logs are in this one for convenience -
but I prefer wood. This one is in our office in Independence, MO.
HearthMasters Herringbone design: Herringbone Bob Hart Rumford using the
Hart Rumford form for the smoke chamber throat - this was built by Gene
for the 2013 NCSG workshop and the form is still in place. The
herringbone pattern was made using firebrick shiners (the large flat
side of the brick showing).
It can also be built using a stretcher layup with the long thin side of
the brick showing, which takes twice as long to build.
This is the Hart/Rumford form from the back: the form allows us to build
a smooth throat which also serves as the supporting lintel, so no extra
lintel is required. This is a straight Rumford being built for the NCSG
convention workshop. Gene wanted to show a standard brick layup as
well as the herringbone.
