4. Forced-air gas - Wikipedia

   en.wikipedia.org/wiki/Forced-air_gas

   Gas-fired forced-air furnaces have a burner in the furnace fuelled by natural gas. A blower forces cold air through a heat exchanger and then through duct-work that distributes the hot air through the building. [2] Each room has an outlet from the duct system, often mounted in the floor or low on the wall – some rooms will also have an ...

5. Furnace (central heating) - Wikipedia

   The fourth category of furnace is the high-efficiency condensing gas furnace. High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. 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 ...

6. Phase-out of fossil fuel boilers - Wikipedia

   en.wikipedia.org/wiki/Phase-out_of_fossil_fuel...

   The phase-out of fossil fuel boilers is a set of policies to remove the use of fossil gas (or "natural gas") and other fossil fuels from the heating of buildings and use in appliances. Typically gas is used to heat water, for showering, or central heating. In many countries, gas heating is one of the major contributors to greenhouse gas ...

7. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   The conceptual difference is mainly in which side the feedback is taken from. A pressure regulator is a valve that controls the pressure of a fluid to a desired value, using negative feedback from the controlled pressure. Regulators are used for gases and liquids, and can be an integral device with a pressure setting, a restrictor and a sensor ...
