Forced air heating works by the warm air being pumped through the system and pipes so that it radiates the heat out into the room. This is a quicker but more expensive way of heating than convection.
Forced convection. Heat is transferred through the air in the room by the movement of the air from the heating vents.
Forced air heating provides quick and even distribution of heat throughout a space, leading to faster warming of the environment. It also allows for the integration of air filtration systems to improve indoor air quality. Additionally, forced air systems can be easily combined with central air conditioning systems for year-round climate control.
Radiant heaters supply heat directly to the ceiling, floor or walls of a home. They use radiant heat transfer, which is heat moving directly from the hot surface to the objects or people in the room. This is the same effect as when you can feel the heat of stove burner from across the room. This type of heating is more energy efficient than forced-air heat because no heat is lost in the duct work. Since there is no moving air, it is better for people with allergies.
There are many different ways to use radiant energy to heat your home including radiant flooring, radiant electric heating, radiant tiles... The site in the related links has tons of information on radiant heating. Technically, "radiant" heating is used to distinguish from "forced air" systems. In a radiant system the radiant elements emit heat and in an forced-air system the furnace heats air, which is then moved to where the heat is needed. A radiant system can be electrical, hyrdonic or steam-driven. For instance, a hydronic boiler heats water to about 180 degrees and uses circulators (forced hot water) to move the heated water to a finned-tube, floor-tubing, wall-tubing, or cast-iron radiator, heating the radiator, radiating heat into the room. The cooled water then flows back to the boiler to be heated again.
The primary function of a forced air furnace is to heat air, which is then distributed throughout the home via ducts to provide warmth to the living spaces. This type of furnace uses a blower to push the heated air through the ductwork system, ensuring consistent and efficient heating.
A forced air heating system uses a furnace to heat air, which is then distributed throughout the building via ductwork and vents.
Convection
Forced air heating
A forced-air heating system includes fans to circulate warm air throughout the space. The warm air is generated by a furnace or heat pump and distributed through ductwork to different rooms in the building.
Forced air heating offers several advantages, including rapid heating of spaces due to the efficient circulation of warm air through ducts. It allows for zoned heating, enabling different areas of a home to be controlled independently for personalized comfort. Additionally, forced air systems can integrate with air conditioning and air filtration systems, improving overall indoor air quality. The system is also relatively easy to install and maintain compared to other heating methods.
Near The Floor
Room air is drawn into the return air ducts and proceeds to a squirlcage or "sirocco" fan. The air is then discharged into the furnace's heat exchanger where the hot flue gases from the fire are cooled by the air and the air is warmed. This warm air is then forced through the heating supply ducts and up through the warm air registers in each room. Forced air systems can also include a humidifier, to add moisture to the air, filters to clean the air. and special filters to remove odors or ultra-violet lamps to sanitize the air.
No, in Canada, a forced air heating system is most common as it is relatively low cost source of heating. With a forced air heating system, heat is usually delivered through a metal duct system throughout a house or building.
A forced hot water heating system is more energy efficient, provides consistent warmth, and is quieter compared to other heating systems like forced air or electric baseboard heaters.
Convection.
In a forced-air heating system, a blower motor pushes warm air produced by a furnace through ductwork to different rooms in a building. As the warm air rises, cooler air is drawn into the ducts to be heated, creating a continuous circulation of air by convection. This method efficiently and evenly distributes heat throughout the space.
