... the result of air’s lower density at elevated temperatures and its affinity to rise. Cooler air sinks due to the increase in density.  4, record 1, English, - natural%20convection

Record number: 1, Textual support number: 1 OBS

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

Even though electric heating is not new, forced air electric furnaces have been available in large quantities for only a few years. Electric furnaces, although similar in appearance to gas furnaces, are quite different. They do not require gas piping or venting. They do, however, require that high capacity electric circuits be installed to the furnace. Electric furnaces are more flexible than gas furnaces because there is no specific position in which to install them. The only requirement is that all components be accessible for installation and service.  2, record 2, English, - electric%20furnace

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 12, English, - forced%20air%20wood%20furnace
