Why do flues in the summer on a water heater have a lower draft? Because I said So!

Are flues heat exchangers that are supposed to cool the flue gases down? Maybe

Why were the flue venting tables produced by a computer and not field testing? Laziness

If you put some oil in the bottom of a glass does it rise or get displaced when adding water? YES

Do Flue Liners increase flue temperatures avoided condensation? No, Flames increase flue temperatures. Anything after that will cool flue temperatures. DAH!

Why do the GAMA/AGA state they cannot be used in windy conditions? Nobody knows

What flue material keeps the flue gases the hottest and not absorb excess heat? Good Question!

When venting into a chimney, we want the flue temperature to stay hot until the exit. Agree!

I hope this makes the whole subject clear as mud!
