Rumford fireplace in a New England home. A Rumford fireplace, sometimes known as a Rumford stove, is a tall, shallow fireplace designed by Sir Benjamin Thompson, Count Rumford, an Anglo-American physicist best known for his investigations of heat.
A Franklin stove. The Franklin stove is a metal-lined fireplace named after Benjamin Franklin, who invented it in 1742. [1] It had a hollow baffle near the rear (to transfer more heat from the fire to a room's air) and relied on an "inverted siphon" to draw the fire's hot fumes around the baffle. [2]
Besides its use for domestic heating, in winter people may sleep on top of the stove to keep warm: the large thermal mass (a proper Russian stove weighs about two tonnes) and layered design (in many variants the hot flue is separated from the outer brick shell with a layer of sand or pebbles) ensure that the outer surface of the stove is safe ...
Even a very efficient traditional fireplace only operates at about 15% efficiency. This is because most of the hot air generated by the fire travels up the chimney due to convection. A traditional fireplace can also draw hot air in from the room and expel it through the chimney, further lowering the efficiency. The design of the direct vent ...
Manufactured fireplaces are made with sheet metal or glass fire boxes. Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes. A few types are wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces, and fixed or free standing electric fireplaces.
Perhaps because of the complexity of casting a metal model, Hubley's range of marques for the kits was not that wide – basically a 1:20 scale range of Ford Model As and 1932 Chevrolets, a 1:22 scale range of Packards, and two 1:18 scale Duesenbergs. The small range was made up for, though, in the number of variations for each car model.
