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.

No.

But trust me on this one- I've seen it- a fan is a **LOT** quieter than an air conditioner! You can hardly tell its on, yet the installation I saw kept the room cool despite a pair of class A triode OTLs with 42 power tubes per channel making over 500 watts. Yet the fan was a whisper.

SS output and tube input sections.

Hybrid amps can be fairly cool.

But, a 10-15watt per channel integrated tube amp, is still going to put out a good ~100 watts of heat.

LTA is a good rec but also smaller low powered amps won't heat the room overly much. My amps been playing for about an hour just held my hand over it and its barely warm. That's a 17 watt pushpull amp, a SET amp would also likely be cooler. How much power do you need?

bottom line, any tube power amp with any meaningful power output will have output tubes that will provide a decent amount of heat

flea watt amps still produce heat - 2x 300b’s or 211’s or 845’s or el84s - of course then it is just a matter of degree, one person’s ’minimal and acceptable’ is another’s ’too much’...

hybrid amps might be the answer... really only low level signal tubes produce what most folks would consider insignificant amounts of heat

Do like many do a very good SS amp like high quality amplifier
and a Vacuum tube preamplifier a great combination of punch and dynamics, and still get some tube soundstaging and layering.
