Are there any tube amps that don't give off any---


HEAT!! 
I have a very small dedicated listening room, and so I was wondering IF there are any tube amps..I guess hybrid or all tube ( although more all tube)- that simply give off NO heat or very very little heat after full warm up. Since the climate seems to be getting hotter, it would be nice to have the benefits of a tube amp with no heat whatsoever. ( is this even possible?). 
Running AC isn't my preferred way of listening in a small room, so this question is now on my mind. I do not want to consider Class D solid state amps...as I know they are an option from a heat perspective...but just tubes.

Here’s a great tweak that no one knows about.

Place your tubes in the refrigerator overnight, preferably the vegetable crisper, for 8 hours before listening.  The next listening session, your tube amp won’t produce any heat whatsoever!

Ok, don’t do that - instead, get yourself one of those small computer fans and for a few dollars, your tubes will run cool and you’ll extend tube life too.
I have a PrimaLuna DiaLogue Premier HP and not only does it sound great, but it puts out 75 watts and does not heat the room up.  As others have noted, all tubes give off some heat, but this amp runs very cool and definitely a lot cooler than my Class A SS amp
Croft Integrated Amplifier. The best hybrid amp period. Heat generated is minimal and sound is the best I've heard. 
I havea  Defy 7 , has 12 6550's, Honestly heat has not been a  issue, room 10x12 8 ft ceiling,, here in new orleans 90% humidity, I mean yeah in summer i run a/c as needed...
 , but on cool/fall days ,
 a/c is not needed. 
You'll be fine with a  mid size tube amp
