When your home’s gas boiler is working correctly, it produces water as a by-product known as condensate. It’s removed from the boiler by the condensate pipe. In cold weather, it’s possible for this pipe to freeze, stopping your boiler from working.
Your boiler might make a gurgling noise or show an error code if it has a digital display. There is usually no need to worry, you can easily defrost a frozen condensate pipe yourself. Watch this video to learn how!
