  2. Furnace (central heating) - Wikipedia

    en.wikipedia.org/wiki/Furnace_(central_heating)

    The fourth category of furnace is the high-efficiency condensing gas furnace. 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 ...

  3. Annual fuel utilization efficiency - Wikipedia

    en.wikipedia.org/wiki/Annual_fuel_utilization...

    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 ...

  4. Forced-air gas - Wikipedia

    en.wikipedia.org/wiki/Forced-air_gas

    High-efficiency condensing furnaces condense the water vapor (one of the by-products of gas combustion) and extract the latent heat to pre-heat the incoming furnace airflow, using a second heat exchanger. [2] This increases the efficiency (energy delivered into the building vs. heating value of gas purchased) to over 90%.

  5. Condensing boiler - Wikipedia

    en.wikipedia.org/wiki/Condensing_boiler

    Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.

  6. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    Annual greenhouse gas (GHG) savings from using a ground source heat pump instead of a high-efficiency furnace in a detached residence (assuming no specific supply of renewable energy) Country Electricity CO 2 Emissions Intensity GHG savings relative to natural gas heating oil electric heating; Canada: 223 ton/GWh [36] [37] [38] 2.7 ton/yr: 5.3 ...

  7. American Recovery and Reinvestment Act of 2009 - Wikipedia

    en.wikipedia.org/wiki/American_Recovery_and...

    House – $4.3 billion to provide an expanded credit to homeowners who make their homes more energy-efficient in 2009 and 2010. Homeowners could recoup 30 percent of the cost up to $1,500 of numerous projects, such as installing energy-efficient windows, doors, furnaces and air conditioners. Senate – Same. Conference – Same. Unemployment

  8. Energy Star - Wikipedia

    en.wikipedia.org/wiki/Energy_Star

    Energy Star (trademarked ENERGY STAR) is an energy-efficiency program administered by the U.S. Environmental Protection Agency (EPA) in partnership with the U.S. Department of Energy (DOE). [2] [3] [4] The EPA establishes energy efficiency specifications, and those that meet these specifications are eligible to display the ENERGY STAR logo. [5]

  9. Thermal efficiency - Wikipedia

    en.wikipedia.org/wiki/Thermal_efficiency

    For energy-conversion heating devices their peak steady-state thermal efficiency is often stated, e.g., 'this furnace is 90% efficient', but a more detailed measure of seasonal energy effectiveness is the annual fuel use efficiency (AFUE).
