Q: Is a furnace a device used for high-temperature heating? ¶
Q: Is a furnace a major appliance that is permanently installed to provide heat to an interior space through intermediary fluid movement? ¶
A: Yes, and which may be air, steam, or hot water.
Q: Were furnaces physically much more compact than the previous styles? ¶
Q: Is a furnace more commonly called a boiler? ¶
Q: Was a furnace used to replace the big? ¶
A: Yes, and natural draft systems, and was sometimes installed on the existing gravity duct work.
Q: Is a furnace the forced-air? ¶
A: Yes, and atmospheric burner style with a cast-iron or sectional steel heat exchanger.
Q: Is a furnace typically the cost for installation? ¶
Q: Were furnaces adapted with electric blowers to aid air distribution and speed moving heat into the home? ¶
Q: Is a furnace the forced draft? ¶
A: Yes, and mid-efficiency furnace with a steel heat exchanger and multi-speed blower.
Q: Is a furnace a below, through air return registers in the floor, and the lesser density of warmed air causes it to rise in the ductwork? ¶
A: Yes, the two forces acting together to drive air circulation in a system termed 'gravity-fed'. The layout of these 'octopus’ furnaces and their duct systems is optimized with various diameters of large dampered ducts.
Q: Is a furnace an industrial furnace used for many things? ¶
A: Yes, such as the extraction of metal from ore or in oil refineries and other chemical plants, for example as the heat source for fractional distillation columns.
Q: Are furnaces used? ¶
Q: Are furnaces relatively inexpensive since the technology is rather simple? ¶
Q: Were furnaces still big and bulky compared to modern furnaces? ¶
A: Yes, and had heavy-steel exteriors with bolt-on removable panels.
Q: Is a furnace the high-efficiency? ¶
A: Yes, or condensing furnace.
