How to defrost a condensate pipe
02 November 2023
Should you pour boiling or hot water on a frozen condensate pipe?
Never pour boiling water onto your condensate pipe, as it might cause it to crack, warp or melt. We recommend only pouring hot or warm water onto your problem pipe once it has had time to cool.
If you’re using a kettle, make sure you’ve let it cool down for at least 15 minutes after boiling before using it. It’s always a good idea to test the temperature before pouring the water onto the pipe but make sure that you don't scald yourself when doing so. The ideal temperate for water to pour over a frozen condensate pipe is somewhere between 60°C and 70°C.
You may want to follow this up by using a hot water bottle or a heat pack against the pipe to help it thaw out thoroughly over a longer period of time.
Be careful when pouring the water – it may freeze on the ground and become a slip hazard.
A frozen condensate pipe can be an inconvenience that can lead to bigger issues if left untreated. However, with a few easy steps, you can usually thaw your problem pipe and restore your heating system to its usual function.
