How Does Central Heating Work?


Feb 18, 2020

central-heating

There are many different ways to heat a home, ranging from the traditional method of a wood fire to the more modern central heating system. Today, central heating systems are far more common as a main source of heat for a home.

How Does Central Heating Work?

Central heating systems are commonly located in your garage, basement, or a storage closest and usually comprised of a simple heating process: burners that burn fuel or create steam to generate heat, heat exchangers to warm air or water, and blowers to pass air through the home via vents or pipes to push steam through radiators. They are typically run from a large heating appliance, such as a furnace or boiler.

In the case of a furnace, combustion gases are created by burners in the furnace and then passed through a heat exchanger. Air that’s in your home is blown across this heat exchanger where it is warmed, and then blown through the ducts of your home to bring it to a comfortable temperature. During the summer months, a similar process is used to cool the air in your home.

In most modern homes, ducted central air systems are the preferred means of central heating and cooling. If you’re wondering “how does central heating work?” or “what type of heating system is in my home?,” then rest assured: you can easily figure this out by checking your heating appliances. If you have an air conditioner, heat pump, or furnace, then you have a ducted air system.

What Are the Benefits of Central Heating?

It’s a Money-Saver

When used effectively, modern central heating can reduce energy bills all year around. Upgrading an old, outdated heating system to a modern central heating system could cut your annual gas bill by up to 30 percent. Talk with an expert near you to get an estimate on exactly what a new system would cost, and what it could save you in the long run.

It’s Better for Your Health

A central heating system is actually better for your health in a variety of ways than many other heating methods. Asthma, bronchitis, and even heart attacks and strokes are known to be reduced by homes utilizing a well performing central heating system since these appliances do a better job at keeping the air consistent and clean in your home. An efficient central heating system will reduce the amount of condensation and mold growth in a home as well.

It’s More Eco-Friendly Than Alternatives

Central heating systems can lower the cost of bills while also reducing the amount of carbon dioxide emissions.  Gas central heating systems only emit water and small amounts of carbon dioxide. This means they have a much smaller carbon footprint than a lot of outdated heating system alternatives, especially ones that run off oil.

Tips for Maintaining Your Central Heating System

When the temperature outside drops, you don’t want to find yourself in a place where your central heating is not working. The best way to prevent such an inconvenience from happening is to be sure to keep your system well maintained. While you should schedule a regular maintenance inspection with a licensed professional before each heating season begins, here are other ways to keep your central heating system well maintained throughout the winter:

  1. Clean or replace filters every 30 to 90 days.
  2. If you have a furnace system, make sure your vents aren’t blocked and air can flow freely.
  3. Reduce your home’s heat load by ensuring all doors and windows are properly sealed.
  4. Get your vents and ducts cleaned regularly.
  5. For any gas furnace, make sure the exhaust flue leading to the outdoors is kept clear.

If you find that your central heating is not working, and no troubleshooting efforts have worked, then be sure to consult a professional right away to prevent any additional damage.
