The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...
High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as compared to a mid-efficiency forced-air or forced-draft furnace, is the ...
Such a system contains a boiler, furnace, or heat pump to heat water, steam, or air in a central location such as a furnace room in a home, or a mechanical room in a large building. The heat can be transferred by convection, conduction, or radiation. Space heaters are used to heat single rooms and only consist of a single unit.
By 2008, a report by the United States Department of Energy ranked the firm as fifth in the US in the central air conditioner and heat pump market with a 12% market share (behind UTC/Carrier with 27%, both Goodman/Amana and American Standard/Trane with 14% and Lennox with 12%), while in the residential gas furnace market as of 2008, the company ...
Washington routinely delivers one-quarter of U.S. hydroelectric generation, and hosts the nation's largest capacity power station at Grand Coulee Dam. 60% of Washington households use electricity as their primary heating fuel, unlike most households in other U.S. states that typically utilize natural gas. [3] Washington electricity production ...
The Census Bureau adopted metropolitan districts in the 1910 census to create a standard definition for urban areas with industrial activity around a central city. [11] At the time, Seattle had the 22nd largest metropolitan district population at 239,269 people, a 195.8 percent increase from the population of the equivalent area in the 1900 census. [12]
