Picture an oil filled space heater no thermostat switched to the 15KW

Picture it in a closed room with no thermostat in a house that is kept
at 68 F by a thermostat in another room. Assume that the heat from the

Now picture the space heater sitting outside on a 35 F day.

Does it use the same amount of electricity in both situations?

yes, since in both cases it runs full on
