How to fix a frozen condensate pipe?

If you are unfortunate enough to have encountered a frozen condensate pipe, then don't panic! SJL Plumbing have outlined a few steps that you can take to attempt to fix any damage and get your boiler working again!

Diagnosis:

If your boiler is no longer turning on, or you are getting no hot water or heating in your home, then one of the first things that you should be is to establish if the issue actually isolated to your condensate pipe. If your condensate pipe is frozen then your boiler will most likely have a flashing amber light on the front and display a fault code. The fault code will be model-specific, so look the code up on the internet or manufacturer's guide to find out what the problem is.

Turn Boiler off then on again:

The next step you should take is to reset your boiler to check if the fault code still displays. If the pipe was frozen but has since thawed then the errors present on your boilers dashboard may no longer be applicable. Try resetting your boiler, but if the fault indicators are still present then you will have to try an alternative method.

Check external pipe

The purpose of your condensate pipe is to remove water from the boiler and dispose of it outside. There will be a plastic pipe coming from where your boiler is located, running to the outside wall of your property. 

It is possible that the pipe that is exposed to the elements has frozen over, and therefore, the pipe could be blocked as any water inside has become ice. 

Solution: Thawing

The easiest way to deal with a frozen condensate pipe is to thaw it so that it defrosts. 

In the same way that you defrost your windscreen on a frosty morning, you should get a few jugs of warm (not boiling) water, and pour it over the pipework that is outside your property.

Prevention: Lagging

We advise that you avoid freezing pipes by purchasing some pipe lagging from your local DIY shop at a minimal cost in order to insulate your pipes in preparation for Winter!
