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.

If you are actually one of the very few serious contributors here, punch a small hole in the wall and put the amps in the next room.  Nobody says they HAVE to be here or there.

@daveyf  This isn't a bad suggestion. 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. Of course our amps have balanced inputs so its easy to run long interconnect cables to make that possible. But you could do the same thing if you got some decent line transformers (so as to convert from single ended to balanced and back again at the amplifier) so you could run the long interconnect cables.

I know two people have already mentioned the Carver 275 but without much context. Carver runs the output tubes much cooler than typical, so he can guarantee them for 5 years. The 275 is sort of a miracle amp - it runs just a little warm, weighs only 19 lbs, yet drives my low-impedance  Wilson Sabrinas spectacularly.

if your looking for tub sound with minimal amount of heat, I’d look at a hybrid amp like the one Lector puts out. They’re made in Italy and sound as good as any full fledge tube amps. I run this amp all summer long and switch to AudioValve Baldur during the winter. The Baldur’s have 10 tubes per side and sound incredible. I highly recommend the lector’s for your room setup

YES! Rogue Audio Sphinx. Hybrid. Tube Pre, Class D output.Sounds lovely. Runs cool.I got mine in early September, this year. It is now my primary unit.My room is small, 10' x 15' and I live in Tucson Arizona and temp here have run 100 degrees plus all through September.
Sound quality is a big improvement over other pure class D's I've had and frankly, better than other Class AB's I've had.Never had a pure Class A - all tube. Way too hot for AZ in my opinion.
