|In response to Re: BOILERS|
: WHAT IS THE DIFFERENCE BETWEEN A CONDENSATING BOILER AND A NON-CONDENSATING BOILER?
I must presume we are talking about an oil or gas fired boiler as opposed to an electric. With that understanding, we must first recognize that these are 'systems'. The condensating boiler system extracts more heat from the boiler into the medium resulting in a much lower exhaust temperature. All combustion produces water as a by product, and normally it dissapears up the chimney as vapor. A conensating system takes more heat out of combustion therby reducing the exhaust temp. to the point that this water vapor condenses into a liquid that must be disposed of. It also requires exhaust materials that are resistant to corrosion and plastic exhaust flues are now the material of choice. A condensating furnace or boiler no longer needs a high temperature chimney, as a simple plastic exhaust pipe is all that is necessary, as well as an appropriate drain for the condensate. These condensating systems extract more heat from your fuel source making them 20-35% more cost effective than non-condensating systems.
Hope this helps AALPHAWOLF
