Woke up without any hot water as my pipes froze. For those of you in warmer climates, hot water pipes ALWAYS freeze before cold. No idea why...

At a guess, I'd say the hot water pipes are either smaller than the cold pipes (less water = faster freezing)

Hot water has less dissolved air/oxygen in it than cold water. That's why hot water in the ice cube trays will freeze faster than cold water.

Yeah, that might be more the case as hot water pipes are the same size as cold water pipes. My understanding was that this was one of the mysteries of physics. Like why coffee stains form rings instead of a patch (althoguh that one was solved...)
