How Are Forced Air Heating Systems Made?



An alternative heating method that uses forced air to heat a space is known as Forced Air Heating. The mechanism of this system is similar to that of an air-heater; however, the air is heated by an electrical current and does not use fuel combustion. A single thermostat controls the heating system and automatically turns the system on or off based on the current temperature setting. The air is fed through ductwork or directly into the room using a supply line. When the system is on, warm air is pushed into the room and forced through the ductwork or directly into the heating element.

In order to understand how a forced air heating system works, you must know some of the different parts it uses to provide its heat. There are four different parts that make up the entire system. These are the boiler (also known as furnace), the furnace unit, the ductwork and the heat exchange. Each of these parts functions differently, but they are connected to each other in a system. The boiler heats water that is required for the various systems and then sends it to the furnace unit. When a fire is placed inside the furnace unit, it is allowed to heat up the water and create steam, which then forces the steam through the ductwork into the rest of the home.

The heat exchangers located between the furnace and the heat exchange are what allows the air to be forced through the ductwork or into the room. The heat exchangers are made of many small tubes, each with a handle. Hot air is pushed through the tubes while cold air is sucked through the handle. The hot air moves out of the top of the furnace unit while cold air is forced through the tube. This is then combined with the air that is drawn through the ductwork to the rooms.

Another alternative in forced air heating system is a heat pump. Heat pumps work in much the same way as a furnace does, only it is not powered by natural gas or oil. Instead, the heat pump uses electricity to heat water that is then used to provide heat for the home. This alternative is generally more energy efficient than furnaces or heat exchanges. However, the process is much slower. It can take thirty to sixty seconds to heat a one thousand gallon water tank.

Ductwork plays an important role in forced air heating systems. The ducts allow the heated air to travel throughout the house. Along the way, the ductwork also removes heat from the rooms. In addition, the ducts have smaller bends that reduce the amount of draft you will experience. This is because most homes have at least two sets of ducts; one set going from the furnace to the outdoors, and another going from outdoors back into the house.

In a forced air heating system, the ducts deliver the warm air to the different rooms. The indoor units are usually vented using a return air vent or a factory fresh air duct system. The outdoor ducts can be vented to permit warm air from the outdoors to be indoors. When the indoor units are vented, they are often held open with a return air vent or a factory fresh air vent. The factory fresh air duct system delivers fresh air to the rooms and these are ducts that need to be sealed tightly to eliminate odors. The return duct system, or venting, is usually a part of the central air conditioning systems.

The most traditional and most energy efficient is the forced-air boiler or furnace. The forced-air furnace includes a separate water holding tank along with the condenser, expansion vessel and combustion chamber. The water tank is usually in direct contact with the condenser so that the two liquids are heated to separate temperatures. A gas line connects the water tank to the condensing unit.



Forced-air furnaces are typically powered by liquid petroleum gas (LPG) which is recovered from natural gas and other resources. Some central air conditioning systems operate on heat recovery through electrical heat recovery which is also sometimes called “eCO” or “ero” systems. The most efficient forced-air heating system utilizes a closed-cycle induction cooling fan. This type of system must have a proper duct system installed so that all incoming air and cooled air will be evacuated properly.
