Will pipes unfreeze themselves?
You might be tempted to wait for the pipes to thaw out by themselves. But keep in mind: Depending on the weather, the process can take days. Pipes typically don't freeze until the temperature dips to 20 degrees Fahrenheit.
What temperature will pipes burst?

When should I be worried about pipes freezing?

Will moving water freeze at 32?
Water freezes at 32°F, regardless of whether it is moving.
In still water, such as lakes and ponds, the top of the water freezes first, and since ice is less dense that liquid water, it remains on the surface and insulates the rest of the water from the cold.
Which one freezes faster hot water or cold water?
Hot water freezes faster than cold, known as the Mpemba effect. The Mpemba effect occurs when two bodies of water with different temperatures are exposed to the same subzero surroundings and the hotter water freezes first.
Why do hot water pipes burst?
Hot water pipes are more likely to burst because the initially higher temperature of the water in them makes the formation of ice crystals more difficult. Then, when freezing does occur, it occurs rapidly, quickly blocking the pipe and trapping water between itself and the closed valve.
Can just a hot water line freeze?
The only way to fix a frozen hot water pipe is to thaw it. If you are still not sure, feel the pipes. The hot water pipes will be warm and there will be a noticeable difference where the frozen pipe begins. It will, literally, feel ice cold.
