I'm living in an old, drafty rental in Melbourne, and the nights are getting really cold. My apartment doesn't have a built-in heater, and my landlord won't let me put in anything permanent, so I'm trying to figure out a way to stay warm without jacking up my power bill. I came across some portable AC rentals that have 4.0kW reverse-cycle units for both heating and cooling. I'm not sure if renting one of these is worth it compared to just buying a cheap space heater. Has anyone tried using the 4.0kW models for heating a room, and are they quiet enough to sleep with?
