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.

David Berning is known for his high efficiency, long tube life, low heat tube designs.

Less expensive models/designs are offered by Linear Tube Audio.

The current David Berning branded line is more upscale/expensive.

I'd ask them if they have any heat measurements they would care to share.

No reviews yet, but the amp you seek is the Entropic Anti from Unicorn Audio. It uses tubes hand made in Utopia from pure unobtainium alloy imported from Krypton.

The tubes our amps utilize are called, "thermionic" because their cathodes must be heated, to emit electrons.             Thus far; no one’s developed another method, regarding vacuum amplification/rectification (except, perhaps, Unicorn Audio).

If you use a higher efficiency speaker you can generally use a lower powered amp.  In addition, some designs use less power and put off less heat.
