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.
This is especially ineffective when the fire is first lit, and the temperature and density of the smoke are closer to the ambient air.

The problem with this is that sorting and storing these plans is a challenge, and it is difficult for people to update their fire plans. As a result, only half of the required buildings have fire plans, and of those, only around 10 percent are up-to-date. [16]
For example, in an office building classified as light hazard, a typical design area would be 1,500 square feet (140 m 2) and the design density would be 0.1 US gallons per minute (0.38 L/min) per 1 square foot (0.093 m 2) or a minimum of 150 US gallons per minute (570 L/min) applied over the 1,500-square-foot (140 m 2) design area.
New codes and standards introduced around 2010, especially the new UL Standard 2572, the US Department of Defense's UFC 4-021-01 Design and O&M Mass Notification Systems, and NFPA 72 2010 edition Chapter 24, have led fire alarm system manufacturers to expand their systems voice evacuation capabilities to support new requirements for mass ...
The electric fire was invented in 1912 [2] and became popular in the 1950s. [3] Electric fireplaces found in 1950s homes were typically small and could be easily moved. [4] Techniques for electrical "flame effects" have been around since at least 1981. [5] Commercial electric fireplace techniques include the Optiflame, introduced in 1988 by ...
