  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. Heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Heat_exchanger

    A waste heat recovery unit (WHRU) is a heat exchanger that recovers heat from a hot gas stream while transferring it to a working medium, typically water or oils. The hot gas stream can be the exhaust gas from a gas turbine or a diesel engine or a waste gas from industry or refinery.

    en.wikipedia.org/wiki/Glossary_of_HVAC_terms

    A component of an HVAC system that adds heat to air or an intermediate fluid by burning fuel (natural gas, oil, propane, butane, or other flammable substances) in a heat exchanger. gas furnace heat exchanger A gas furnace heat exchanger is responsible for the transfer of heat from inside the furnace into the air outside the furnace.

  5. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    Electric heating or resistance heating converts electricity directly to heat. Electric heat is often more expensive than heat produced by combustion appliances like natural gas, propane, and oil. Electric resistance heat can be provided by baseboard heaters, space heaters, radiant heaters, furnaces, wall heaters, or thermal storage systems.

  6. Heating, ventilation, and air conditioning - Wikipedia

    en.wikipedia.org/wiki/Heating,_ventilation,_and...

    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.

  7. Heat recovery ventilation - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_ventilation

    Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

  8. Recuperator - Wikipedia

    en.wikipedia.org/wiki/Recuperator

    Types of recuperator, or cross plate heat exchanger. A recuperator is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat. Generally, they are used to extract heat from ...

  9. Forced-air - Wikipedia

    en.wikipedia.org/wiki/Forced-air

    Heat is produced via combustion of fuel. A heat exchanger keeps the combustion byproducts from entering the air stream. A ribbon style (long with holes), inshot (torch-like), or oil type burner is located in the heat exchanger. Ignition is provided by an electric spark, standing pilot, or hot surface igniter.
