During extreme cold conditions, your boiler may develop a fault, this could be due to a frozen condensate pipe. A common symptom of this would be, the boiler may start to develop a gurgling noise, it will fail to start and if it has a display it will display a fault code.
Why does my condensate pipe keep freezing?
A condensing boiler turns the hot exhaust gases into water via a heat exchanger. This reclaims 20% of the heat energy. This water is taken out of the property through a plastic condensate pipe which can be prone to freezing when temperatures are below freezing.
Why is my combi boiler overflow dripping?
Your boiler’s overflow pipe may leak water if: The boiler has built up too much pressure due to the expansion vessel failing or losing its charge. The pressure relief valve is not seated correctly, causing water to pass by it.
Can frozen pipes stop boiler working?
“If they freeze then condensate will build up in the pipe and then back up into the boiler – which will stop working. “Boilers are smart, they know when they should stop working. “If your boiler breaks down during freezing conditions it is the first thing you should check.”
