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.

Highly recommend Quadrature Z mono blocks by David Berning.  I had mine for many years and they ran very cool, even with long hours of operation in the summer.  Previously I used Lamm M1.1 mono blocks also for many years. They were hot by comparison especially in warmer weather.  Z's are not cheap. 
I have a Carver Crimson 275. The tubes become warm to touch, but not hot. Same with power supply and output transformers, warm not hot.  Sounds great too!
Warm but not hot is how my amps get now. Problem is, that due to such a small room, warm over time is enough to heat the room considerably. 
I like the idea of maybe rolling in some smaller tubes, which might lead to even less heat. Something I will look into.
Your body temp is typically 98.6 F. That’s equivalent to a pretty darn hot summer’s day. What’s the answer? Additionallly, humans, cows, squirrels, goats, chipmunks, wolves, fox, dogs, cats zebras, elephants all have flatulence....., Getting back to original question, no....
