I'm with jimt...sleep or hibernation instead of a shutdown and restart. Fact is I only do the latter when there's an update to install which requires it or when I'm away for a few days, otherwise it's sleep every night.
Incidently I have the central heating radiator permanently off in the office (hence the name "office"...er hat, coat) and in winter the PC & periphs stay on and keep the room above freezing.
