A B&B we stay at has one of these in a fairly large bathroom.
It looks like a split but is a heating only appliance. Anything that generates heat is going to cost roughly the same amount to operate per kw of heating. Differences will be in the comfort levels they provide and the ‘on’ time, save for the infrared types that heat ‘targets’ not ‘rooms’.
I am not sure if there are differeent versions but the one I mention has controllable oscillating louvers, a timer, fan only, and 2 power levels (1000 and 2000 watts).
