Frozen Pipes when the Temperature is Low
The heat that flows through the pipes prevents them from freezing. A malfunctioning boiler might have frozen pipes at night due to a shortage of enough heat. This happens more in homes that have condensate pipes fitted outside.

These noises can also be a sign of a more serious issue, such as low water pressure, restricted gas flow, or an obstructed flue which can affect the performance and efficiency of the boiler and even pose a safety risk.
If you hear a strange noise from your boiler, it’s recommended to have it inspected by a qualified professional to diagnose and fix the issue.
