When it comes to heating and cooling your home, people often hear that their system is “central.” Central heating and cooling may not be the only way to regulate your home’s temperature and air quality, but it’s certainly one of the most popular methods. Let's define central heating and talk about how it helps keep your home nice and toasty when the weather gets cool.
Parts of a central heating system
Central heating units have a primary heating appliance, such as a furnace, typically located in your basement or garage. All furnaces consist of four main components: burners that deliver and burn fuel; heat exchangers; a blower; and a flue that acts as an exhaust for gaseous by-products. Depending on your situation, region, and needs, you can choose from heating systems running on either gas or oil as fuel or a hybrid packaged system that can use both fuel types.
How central heating works
Combustion gases are generated by the burners in your furnace and passed through a heat exchanger. Air from your home blows across the heat exchanger and is then blown through a system of ducts to distribute around your home. During warm seasons, your heating system works with your central air conditioning. Air is cooled as it’s blown over your air conditioning unit’s cooling coil, often attached to the air circulating fan of the furnace, and then sent through the same air ducts throughout your home.
Is it right for your home?
There are several, affordable options for heating your home. Central heating is a great choice for general comfort and energy efficiency since it’s the tried and true way to get consistent temperatures throughout your entire house, and it can be connected to a central air conditioning unit. But things like the cost to install a central heating unit and the cost and hassle of the system’s required ductwork installation and maintenance cause some people to pause.
