The biggest concern is, of course, safety. You need a space heater with a sensor that shuts off if it overheats and you’re not home to do it yourself (or if you can’t control it remotely with an app). And if you have pets or toddlers, who tend to mess with things that are potentially hazardous, make sure it won’t tip over. If possible, look for one with a timer, a temperature setting and a remote control, so you can monitor it from afar (or rather, another room, without ever leaving your bed).
