Wow... he really is.

Prove me wrong, then! You do realize that you are flowing hot water
back into the system, don't you? You do realize that for that water to
have a cooling affect on the air, that the air has transferred heat to
that water, don't you? So, you do realize that that water, in order to
cool with any noticeable amount, would be quite warm, usually warming
than the ambient air temperature, don't you?
