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.

" you can have the amps on all day and walk up to them and grab a power tube and hang on..."  

Remember Ralph, hot glass looks just like cold glass. This is from personal experience (goes for metal as well).

Small SET amps are fairly cool running and won't heat a room.

True, but this comment (taken out of context) was part of an explanation of how in most cases the filaments are not why tubes run so hot- the 6C33 being an exception.

If you can't take the heat ... stay out of the man-cave!
