2. Forced-air gas - Wikipedia

   en.wikipedia.org/wiki/Forced-air_gas

   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 opening into the cold air return duct. Depending on the age of the system, forced-air gas furnaces use either a pilot light or a solid-state ignition system (spark or hot surface ignition) to light the natural gas burner. [3]

3. Forced-air - Wikipedia

   When the thermostat calls for heat, blower and element come on at the same time. When thermostat is "satisfied", blower and element shut off. Requires very little maintenance. Usually more expensive to operate than a natural gas furnace.

4. Thermal cutoff - Wikipedia

   en.wikipedia.org/wiki/Thermal_cutoff

   A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip, often encased in a tubular glass bulb to protect it from dust or short circuit. Another common design ...

5. Air handler - Wikipedia

   en.wikipedia.org/wiki/Air_handler

   Air handlers typically employ a large squirrel cage blower driven by an AC induction electric motor to move the air.

9. Register (air and heating) - Wikipedia

   en.wikipedia.org/wiki/Register_(air_and_heating)

   The velocity of air through a register is usually kept low enough so that it is masked by background noise. (Higher ambient levels of background noise, such as those in restaurants, allow higher air velocities.) On the other hand, air velocity must be high enough to achieve the desired temperature. [6] Registers are a critical part of the HVAC ...
