Yes, there are two exhaust hoses, one for air out and one for air in. As you get larger or more powerful btu capability.. It seems to be more efficient to have two hoses.
Sorry, there was a problem. Please try again later.The exhaust is actually quite hot (not warm) which surprised me. This is also how the water evaporates from this hot exhaust. Exhausting this back into room would nullify the cooling, I'm sure.
