If you were to have a steady stream of heat...

[Philippine Mango]

lets say you managed to take all sources of heat in your home and channeled it into a room for example or chamber with temperatures around 40*C (so it's not that hot) and I guess compressed it in this area, continuously suppling this area with more and more heat with little to none heat loss, would it continously increase in temperature eventually reaching boiling point or would it stay the same?

I was considering this for Highly technical but....

if gas werent to leave, as pressure increases, tempeaature increases, until eventually you end up dead with a melted shrunken head.

i assume you mean steady conduction/radiation (not convection cause he said stream of heat, not hot air) of a constant amount of power. If so, then no, the temperature would increase until the conduction/radiation away from the object being heated equals the constant heat input. stays that temperature until something else changes.

It would heat up only as hot as the heat you are applying.

Either you DO allow an equal amount of air pumped in to be pumped out, which means the room would never heat up above the temperature of the air being pumped in.

OR you DON'T allow existing air to escape, which means the pressure in the room would infintely increase and thus the room would get really hot, form a star, and then brighten things up with a big supernova before imploding into a black hole. But you'd need a fairly robust air pump for this to happen, though, so if this is for a home project or something then I wouldn't worry about it.

what's the purpose of this contraption. I mean, it's not exactly beneficial to overclocking..

There is a small confusion - if you are adding heat, you add it no matter the existing temperature. If you use some kind of heat transfer system (like heating it with hot water), the heat transfer stops when the heated area has the same temperature as the heating liquid.

Also, the hotter it is a thing (compared to the surrounding area), the more heat will be transferred from it to the surrounding area (by radiation, convection and contact). So, even if you would have a perfect heating device (like a laser that heat something no matter how cold or hot it is), you need special thermoisolation to increase the temperatures. For plasma (very hot ionized gases), the only way to keep them out of contact with the walls is by using magnetic confinement. The walls are made reflective so that radiation (light and heat) is reflected back to the plasma as much as possible. Heating is done by (I don't know sure, but I think) induced currents.
Even in those conditions, the devices (they could be called tokamak - from russian) can not mantain the superheated plasma without energy constantly being entered in the confined space.

It all ends up in a theory like this one: http://www.blakjak.demon.co.uk/gez_ihee.htm
