  2. Furnace (central heating) - Wikipedia

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

    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 ...

  3. 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%.

  4. 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 ...

    (Canada has already required condensing furnaces for residential heating for over a decade.) Close-up of flames on a natural gas furnace burner in the HVAC system of a suburban home in San Ramon ...

  6. 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.

  7. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    At that time central heating was coming into fashion in Britain, with steam or hot air systems generally being used. Details of furnace and expansion tube from Perkins' 1838 Patent. Perkins' 1832 apparatus distributed water at 200 degrees Celsius (392 °F) through small diameter pipes at high pressure. A crucial invention to make the system ...

  8. Glossary of HVAC terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_HVAC_terms

    A type of radiant heating system where the building floor contains channels or tubes through which hot fluids such as air or water are circulated. The whole floor is evenly heated. Thus, the room is heated from the bottom up. Radiant floor heating eliminates the draft and dust problems associated with forced air heating systems. radiation

  9. Fire-tube boiler - Wikipedia

    en.wikipedia.org/wiki/Fire-tube_boiler

    Condensing boilers have a higher seasonal efficiency, typically 84% to 92%, than non-condensing boilers typically 70% to 75%. The seasonal efficiency is an overall efficiency of the boiler over the entire heating season as opposed to the combustion efficiency which is the boiler's efficiency when actively fired, which excludes standing losses.
