Central forced-air heating systems are by far the most popular method for heating homes in North America. This is because they can deliver heated air from a central furnace or heat pump to every room of the house and because a forced hot air system can double-up for the delivery of air-conditioned air and can therefore be used to cool the home on hot days.
The basic components of a forced-air system include:
1) An air handler, which may be either a stand-alone blower cabinet used with a heat pump or a forced-air furnace that includes a blower. 2) A means of heating air, such as gas-fueled burners or electric-resistance heating elements. 3) Ductwork for delivering room air to the heater. 4) Ductwork for sending heated air back to rooms. 5) A a temperature sensing and control system (thermostat) for turning the system on and off.
Of course, forced-air systems include a few other parts and pieces that refine their work, including filters to clean the air, registers to direct and control the flow of air to rooms and, in the case of heaters that utilize combustion for heat, a flue for venting combustion gasses outdoors.
When the temperature control (the thermostat) tells the heating system that room temperatures are below a set comfort level, the air handler will turn on. This will result in drawing room air from a “cold air return” through ductwork into the furnace’s heat exchanger. The heat exchanger is a metal chamber around which air flows and this will heat the air.
The burners or electric heating elements turn on or the heat pump engages to heat the air as it moves through the air handler. The blower then forces the warmed air through a network of ductworkback to the rooms. And the cycle continues until the set comfort level is reached and the temperature control turns the heating system off.
