Facts About Water Pipes Freezing

This winter, I have been performing a lot of thermal imaging inspections to locate exactly where home owners water supply lines are freezing. Home owners are often surprised when their pipes freeze because the house doesn't seem cold. They are often puzzled about why the hot water pipes always freeze first. That tendency seems to defy logic, but there is a good reason for this phenomenon. Hot water pipes freeze faster than cold water pipes because hot water contains less gases and tends to supercool and freeze from the center outwards. Cold water, however, tends to crystallize and form an ice cover, allowing the water to continue flowing under the ice layer.
