Why Bother? (Moscow Phys-Tech)

A physicist and an engineer find themselves in a mountain lodge where the only heat is provided by large woodstove. The physicist argues that they cannot increase the total energy of the molecules in the cabin, and therefore it makes no sense to continue putting logs into the stove. The engineer strongly disagree, referring to the laws of thermodynamics and common sense. Who is right? Why do we heat the room?
