Some fireplace units incorporate a blower, which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room.
Burning Log is a television program which airs traditionally on Christmas Eve or Christmas morning on the Shaw Spotlight community channels in Canada, replacing the remainder of the channel's programming for the time frame.
Rumford wrote two papers [2] [3] detailing his improvements on fireplaces in 1796 and 1798. 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. Subsequent testing of Rumford's designs has shown that their efficiency would qualify them as clean-burning ...
Hot areas are shown in red, cold areas are shown in blue. A hot, less-dense material at the bottom moves upwards, and likewise, cold material from the top moves downwards. Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid.
As with any fire, burning wood fuel creates numerous by-products, some of which may be useful (heat and steam), and others that are undesirable, irritating or dangerous. One by-product of wood burning is wood ash , which in moderate amounts is a fertilizer (mainly potash ), contributing minerals, but is strongly alkaline as it contains ...

Large temperature differences between the outside air and the flue gases can create a strong stack effect in chimneys for buildings using a fireplace for heating. Before the development of large volume fans, mines were ventilated using the stack effect. A downcast shaft allowed air into the mine.
