We’ve already seen a increase in maintenance requests for boilers that have stoped functioning due to the cold weather 🥶 ❄️
How to defrost a frozen condensate boiler pipe
Use hot water – not boiling – heated by a kettle or a microwave and pour over the end of the pipe where it is frozen using a suitable container like a watering can and/orHold a hot water bottle or heat wrap around the condensate pipe.Give the pipe a gentle tap with a wooden spoon or similar to dislodge the frozen water.If the first kettle has no effect, repeat the process a number of times until things start to move.Once the pipe has thawed you should re-set your boiler by holding in the re-set button for 10 seconds and wait for the boiler to re-fire.
Warning
Never attempt to thaw a condensate pipe above waist level, or disconnect the condensate pipe in order to do so.Never attempt to access the condensate pipe or any other pipe work within the boiler. Beware of ice on the ground that will form from the water you have poured.
