Yep, they are supposed to be "warm to the touch" and you have to keep heating them because the pressure drop in the tank cools it, it sounds like hamsterpower had an ideal situation where he had the space and the help to keep everything working smoothly.
If I was air sealing another attic I might get a foam kit instead of the cans and the gun but I would not want to try to work those tanks and heater and everything in a crawl space.
