Well, not having to wake up in the middle of the night is not a small matter. Also, even if the fire goes out you'll get some residual heat and so you have some time to get it going again. This may not be a big deal at 0C, but if it's -20C outside then it may be a higher priority. From various reviews I've read, the heat 'feels' different: not as intense but rather 'softer' and 'even'.
