I truly understand how you feel with the heat that comes with tube amps. In fact, that was the main reason that I switched from using them years ago to focus on solid-state amps.
I was never comfortable in my room because of the heat till I got a small fan that was always on when I was using the tubes. So, maybe I suggest you get a fan that you can keep in the room that can make the room cooler. I don't bother about those issues anymore because I run solid-state amps, and they give less drama, unlike tubes.
