Anatomy of a Condensing Furnace. What Makes it so Cool.

By , About.com GuideNovember 18, 2011

Follow me on:

You hear about high efficiency furnaces all the time but do you know how they work?

Well, high efficiency furnaces work with condensing furnace technology. Unlike older conventional technology furnaces that have hot exhaust flues, the condensing furnace is so efficient and extracts so much heat from the combustion process that its exhaust vent / flue is just warm to the touch, not "burn your fingers hot."

I'll explain what makes the conventional furnace and condensing furnace so different and how the condensing furnace works in the tutorial called Anatomy of a High Efficiency Condensing Furnace. In the tutorial you'll learn the following about a condensing furnace and its components:

  • How a Condensing Furnace is Different
  • Air Recycling / Fresh Air Intake
  • Fuel Combustion
  • Heat Extraction
  • Combustion Exhaust

So take a read of Anatomy of a High Efficiency Condensing Furnace and learn what makes the condensing furnace so "cool!"
