It's a space heater. It's supposed to be "inefficient." The whole fucking point of a space heater is to convert electricity into heat. What the fuck is wrong with you?
EDIT: I didn't expect people who know what they're talking about to reply lmao

They become less efficient at temperatures near or below freezing (below 7 C), firstly because it becomes harder to extract heat from the outside, and secondly because the heat pump will need to switch to a reverse cycle at regular intervals to defrost internal components (usually at temps below 2 C).
