A furnace’s heat exchanger is a set of tubes or coils that are looped repeatedly through the air flow inside your furnace for the purpose of heating air. Simply put, the furnace heat exchanger is the part of your furnace that actually heats the air. It is sometimes call a fire box. The combustion gases involved in this process gets passed through the flue pipe and safely exit the house, usually through the chimney. In this article you will learn more about how forced air furnaces work.

The Importance of Heat Exchangers

The heat exchanger is designed to provide the required amount of thermal energy needed for either heating or cooling a fluid stream in the process. The rate of heat transfer is important for the selection of a particular type of heat exchanger. Since heat exchangers hold dangerous combustion gases, any cracks, splinters or holes can be very dangerous because the gases may end up in your home. This combustion gas spillage can happen whenever fuel is burned and can cause major health problems and even death.

Top 3 Reasons Why Combustion Gases Leak Into The Home

  • Equipment Failure (cracked heat exchanger)
  • Chimney or ventilation problems
  • Pressure Problems (negative pressure causes backdrafts)

When you have a properly working heat exchanger and ventilation system none of the combustion gases should ever make it into the circulation air you breathe.

List of Harmful Substances That Could Be Released

  • Carbon Dioxide
  • Nitric Oxide
  • Nitrogen Dioxide
  • Sulfur
  • Volatile Organic Compounds
  • Hydrocarbons

Cracked Heat Exchanger

Its nearly impossible to tell if you have a cracked heat exchanger, unless you are a professional HVAC technician. The best indication of a heat exchanger problem is with a carbon dioxide detector. If the detector continues to go off, don’t ignore it! Turn all fuel-burning appliances off and call your local Service Professionals. Consider scheduling annual furnace maintenance and make sure you are checking your air filter every 30 days and cleaning or replacing it when it gets dirty. If you have a cracked heat exchanger, you need to replace it or replace the entire furnace.

Understanding important furnace components like the heat exchanger will help you understand what happens when things go wrong. If you haven’t scheduled your furnace tune-up this year, schedule one as soon as possible.
