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

Technically speaking, the answer they are searching for is an electric heat pump mini-split system. These systems are basically air conditioners that push the hot air inside and cold air outside, so they run as heaters. Not sure why it took so long for this to become a thing, but they have efficiencies over 100%, because they aren't converting energy to heat, but using it to move heat. Some are close to 200% efficient.
HVAC contractors don't like to do them though, because its more work for them. Its not what they're familiar with doing. And they don't have to if you don't ask for it. So a lot of HVAC systems are still the old technology, even though heat pumps have been popular and trending for about 10 years now.
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).
My apartment is outrageously hot most of the time (probably because i've practically got whats nearly an almost mini data center runnin in a 1br, no joke I even had stuff rackmounted for a while) , so I got a AC unit, but the windows are all horizontal sliding and fucky, so I had to get one of those weird as free standing deaies with wheels and a tube coming out the back you put out the widow. Sometimes when its actually manages to be cold (recently), I just turn it on without putting the tube out the window. heats things up.
