I'd have to imagine at some point, more heat is leaving the house than entering, and given enough time, inside and outside will eventually reach a cold equilibrium.

Would depend on how well insulated it is, but yeah since homes aren't exactly built to be air tight there's realistically an upper limit to the temperature delta you're going to be able to achieve. Ultimately the question isn't how hot/cold is the inside/outside of the house, but how big a difference are you looking at between those two.
