Ah, of course, thanks! We had a couple of those (still have one). The ones that could only be turned on and off by plugging and unplugging we got rid of a while back -- they were really effective at putting out heat but you didn't dare leave the room or sleep with one on. The one we still have has a tilt feature I like -- if it gets knocked over it turns off (and has a knob for off/low/med/high). Had a kerosene heater for a short while; it was okay, but probably we didn't have the optimal space/size configuration. Took the edge off in the morning though, which was nice. But we didn't keep any of them on overnight or for more than a few hours at a time -- probably saved us from burning them out and starting a fire ourselves...
