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

Do heat pumps maintain that efficiency when there' s no hot air outside to pump in?
Ambient air heat pumps generally work well down to around 20F or so, then effectiveness drops. Still pretty good though.
There's a version that pumps water in pipes underground and uses ambient geothermal heat (because underground temperature stays a constant temperature year-round) that avoids this shortfall, but its more expensive to install because it involves drilling.
Most also have an em heat option for sub freezing temperatures, but that makes them less than 100% efficient because you're heating a coil that's outside and is radiating heat into the atmosphere
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).
