  Rumford fireplace - Wikipedia, the free encyclopedia
Rumford fireplaces are tall and shallow to reflect more heat, and they have streamlined throats to eliminate turbulence and carry away the smoke with little loss of heated room air.
Rumford wrote two papers detailing his improvements on fireplaces in 1796 and in1798.* He was well known and widely read in his lifetime and almost immediately in the 1790s his "Rumford fireplace" became state-of-the-art worldwide.
Rumford fireplaces are generally appreciated for their tall classic elegance and their heating efficiency.

The performance of a fireplace is primarily governed by three factors: fuel combustion, air pressure differential between the firebox and the top of the chimney and temperature differential between air in the room of the fire and that at the top of the chimney.
When the fireplace is constructed on a slab-on-grade it is usually necessary to thicken the slab under the fireplace to support the loads from the fireplace and chimney.
Draft of the fireplace is affected by the dimensions of the firebox opening, the shape and cross-sectional area of the flue and the height of the chimney.

In houses with rooms or crawl spaces below the fireplace, this hearth extension is usually cantilevered and constructed of self-supporting reinforced concrete or "corbel slabs" supported by a masonry stem wall the same size as the wall surrounding the firebox.
Rumford fireplaces are usually about as tall as they are wide but you can vary the height by the number of firebrick courses laid.
When you get the backup block to the top of the fireplace opening, if you are building with the segmented throat system, continue to lay block on each side of the firebox to carry the steel angle which supports the throat tiles.

Rumford recognized that it was the radiant heat generated by a fireplace that actually warmed the room.

A traditional fireplace is equipped with an angled fire back and a lower lip to create a place for the room air and the smoke to roll their way up through the damper and out the chimney.

First introduced by Count Rumford in the 1790s, Rumford fireplaces were a means of improving the heating capabilities of their traditional large, bulky ancestors.
Applying his knowledge of heat to the fireplace, Count Rumford reasoned that the traditional masonry fireplace was not as efficient as it could be because it did not reflect much heat back into the room.
His first change to the traditional fireplace of the day was to move the rear firebox wall closer to the front of the fireplace.

 One Hot Fireplace | THIS OLD HOUSE
The Rumford fireplace, built in the sanctuary where the altar used to be, was to be the focal point of the enormous living room.
In the mid-1700s, Count Rumford (born Benjamin Thompson in Woburn, Massachusetts), the fireplace's creator and namesake, realized that the only useful heat generated by a fireplace is radiant heat, and that in traditional fireplaces, much of this heat mixes with smoke and goes right up the chimney.
But Rumford's real genius was straightening the fireback and rounding the front wall of the throat, essentially creating a nozzle—like an inverted carburetor—that shoots smoke up through the damper and out the chimney, wasting less heat in the process.

The Town and Country direct vent fireplace provides a totally open look as there are no panels or louvers on the top or bottom or at the base of the fireplace.
