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.

@jond  I actually do a seasonal amp rotation, the tube amps for the winter and mostly the ss amp for the summer. Even so, the ss amp heats the room enough within about 1.5 hours that it is time for the AC. 
Swapping out the KT150's for El34's may be an option. The big KT150's do give off some heat. I cannot imagine an amp with 24 of them or more...like the ARC Ref 750 or the upcoming newer version...Total heat engine!

very small room + tube amplifier + heat worries = tube headphone amplifier

"...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."


As much as the tubes may run cooler, the amount of heat in the room will stay the same, I think (theoretically even higher due to fan operation heat). It would not solve the OP’s problem.

"We have a number of customers that have their amps installed in the basement beneath their listening room, near the ceiling so the speaker cables can be kept short."

Very economical and environmentally-friendly version of what is usually called "floor heating".

" 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).
