A Look at the Major Components of Your Home's Central Heating System

Last updated 5 years ago

After returning home on a cold day, you adjust your thermostat and your heating system comes on. Your home grows warm and comfortable while you kick back and enjoy your evening. With a well-tuned heating system that offers uninterrupted comfort, you probably don’t give its inner-workings a second thought.


Behind the scenes, your heating system is composed of several different components working in concert to keep you warm while maintaining energy efficiency. With the right components and regular maintenance, your system can help you find a balance between low utility bills and optimal comfort even during the coldest days of the year.


The very heart of your system is your furnace. This piece of machinery generates heat and distributes warmed air throughout your home using a motor, blowers, valves, and many other parts. Fuel-burning furnaces use natural gas or oil. When heat is called for by your thermostat, the furnace’s burner activates, the flame heats the surrounding air, and the blower motor pushes warmed air into the ducts.


Now that the air is heated, it needs to be distributed throughout your home. Many homes have hot air ducts under the floor, making use of heat’s natural tendency to rise. The furnace’s blower motor pushes this air into the ducts, which is directed as necessary to registers or vents in your home. The vents help evenly distribute the air. Return air ductwork brings cooler air back to the furnace for reheating, and the cycle begins again.


The brains of your system, the thermostat, is a very important component when it comes to energy efficiency and comfort. A programmable thermostat can help you enjoy greater levels of comfort while you’re at home and save you energy when you’re away. Many types of thermostats will even give you reminders when it’s time to change your furnace filter, further increasing your home’s efficiency and comfort.
