bob mentined "Likely only the hot water pipe is split DC, they freeze first." down below - he's right of course but why would that be?
i can see getting ice cubes faster from hot water, cuz you're triggering the freon faster. but we're talking temp & wind chill here, there's no way i can goose that. in open air, you'd have frozen steam like in yellwstone. but why would a hot pipe burst first?

Hey DC, I know it happens but didn't know untill my son the scientist explained it to me like this. It's Momentum of heat change/loss. The hot water needs to lose more degrees to freeze but since it's moving in temp it cracks the Latent heat of fusion (freezing/thawing) faster than water closer to the freezing point. The latent heat thing is a tremendous amount of energy transfer to change state and not change the temp one degree, compared to changing the temp one degree after the change of state takes place. The latent heat is why a heat pump can give you three times the heat from the elecricity that you would get by useing in in a heater. Unfortunatly they don't work too good up by you DC.
Later Bob

because there is little or no air in it to act as insulation

Heating water drives dissolved gasses out of it. The gasses normally act a little like insulation, but in water that has been heated it can't because it isn't there.
