I had the heating company do a routine maintenance on my furnace today and they said I need a new heat exchanger. I have propane heat. The reason was that the flame is too red. He said it should be more of a blue color. He cleaned it out a bit and said the color improved but I still should get a new heat exchanger. Afterword I did a little internet research. It seems the most common reason for a new heat exchanger is that you have a cracked one. He never mentioned that. Does what I am saying make sense? Does getting a new heat exchanger improve my flame color?Thanks!
You were smart in your research, the heat exchanger beyond the flame, therefor does not affect the flame. The burners may need cleaned or replaced, gas regulator may need to checked. Don't know if you have a high efficiency unit that has forced cumbustion air or not, but that could be a source of your problem as well. But to put it in layman's terms, It ain't your heat exchanger.
