The Control System
Your furnace has a control system that regulates the heating of your home. Typically, a sensing device compares the temperature in your home with the target temperature set via the thermometer. Once the furnace receives the signal from the thermostat that the temperature is below the target, the furnace turns on. Then, a valve opens and the burner ignites. Finally, the valve interacts with the thermostat to make sure the temperature remains constant.
The Distribution System
The heat that is generated in a central heating chamber must be distributed through the ductwork in your home to heat your living area.
Here are two kinds are heat distribution systems:
- Vents, ducts and registers: These are systems that use forced-air and heat pumps. In this case, heated air moves from the furnace or pump into your home via ducts. Then, the heated air travels through each room through air vents and registers.
- Pipes: Heated water is distributed from a boiler through a series of pipes, heating your home in the process.
