I assume heat will spread, conduct and transfer if exposed to air or different conductors.
But what happens if heat is contained?
Let’s say I have a box that is made of a hypothetical material that does not conduct heat at all (100% heat escape proof), and in it I contain air with a temperature of 80 degrees.
I then put the box in a freezer.
Will the air inside the box stay at 80 degrees? Or will it decay by itself over time? (And if so, at what rate?)
I ask because I bought a three story house and I’m considering building a constantly very warm “spa” bathroom in the center of the second floor, and my hypothesis is that this will be energy efficient since the bathroom will function as a warm heart that spreads heat to the rest of the house, if heat behaves how I hope it does and doesn’t decay and disappear by itself

Heat is the least organized form of energy. If it can’t get out of the box then it’ll stay in the box. It doesn’t “get tired.”
If you are wishing to have a warm room and the outside is cold, then the best place to put it is central. The heat will find its way out of that box which will heat up the surrounding spaces.
The thinking changes if it’s summer and the exterior walls are hot but you want other rooms cool. The a corner room on the top floor is best because that’s already the hottest location naturally.
