Convection. Process of heat [(transfer of heat) ] carried from one point to another by movement of a liquid or a gas(i. e., air). Natural convection is caused by expansion of the liquid or gas when heated. Expansion reduces the density of the medium, causing it to rise above the cooler, more dense portions of the medium. Gravity heating systems are examples of the profitable use of natural convection. The air, heated by the furnace, becomes less dense(consequently lighter) and rises, distributing heat to the various areas of the house without any type of blower. When a blower is used, the heat transfer method is called "forced convection. "  5, record 1, English, - natural%20convection

Power combustion furnaces utilize a combustion blower which may be located either upstream or downstream from the heat exchangers. If the blower is located upstream blowing the combustion air into the heat exchangers, the system is called a forced draft system. If the blower is downstream, the arrangement is called an induced draft system.  1, record 2, English, - combustion%20blower

Fournaise : Ce terme est considéré comme impropre par les puristes. Selon Dagenais, dans son "Dictionnaire des difficultés de la langue française au Canada", "fournaise" serait un calque de l'anglais "furnace" et nous devrions plutôt dire "chaudière" lorsque le fluide caloporteur est l'eau ou la vapeur et "générateur d'air chaud", lorsque le fluide, est l'air. Cependant, ce terme reste d'usage fréquent au Québec, autant en langue parlée qu'en langue écrite.  3, record 3, French, - g%C3%A9n%C3%A9rateur%20d%27air%20puls%C3%A9

Forced Air Wood Furnaces. Central wood-burning furnaces are controlled by a wall mounted thermostat in the living area. Temperature and fan controls are the same as those found on oil and gas furnaces. Unlike room heaters, which produce a steady heat output by periodic manual adjustments of the draft control, most wood furnaces operate in cycles. A cycle starts with the thermostat sensing that heat is needed in the room where it is located. It signals the furnace control system which opens the combustion air damper and a hot fire develops. When the air inside the furnace's sheet metal casing gets hot, a preset fan control starts the circulating blower and the warm air is moved through the ducts to all areas of the house.  1, record 7, English, - forced%20air%20wood%20furnace
