This kind of comparison always annoys me. Sure the coils are "hotter" but that has absolutely nothing to do with actual energy. Same thing when people bitch "oh my pc is so garbage it runs so hot" when it's some econobox 30w cpu- cool that just means your cooling system is bad or clogged. A machine can be producing 3kW of heat but be at 40C, or 3 watts at 150C.
It doesn't matter that a freezer runs at - 20c and a toaster at 700c. If watts in = watts out it'll stay cold, and if it doesn't, the system will warm up.
