Suppose I heat a room directly by lighting a fire in the room, let's say it is a butane gas fire and it takes n BTU to raise the temperature by 10°C.
Now, suppose I don't like the smell of burning gas fumes and decide instead to move the same gas fire outside and boil water to generate steam to run a generator to produce electricity to power an electric heater in the same room and it takes 3n BTU to raise the temperature by 10°C.
Is there a technical term to descibe the 3 x BTU difference between direct heat and indirect heat in the above?
