Boiler Problems - Frozen Condensate Pipe Work
Posted 2nd March, 2018
If you are having problems with your boiler during the very cold weather it might be that the 'condensate discharge pipe' of your boiler has frozen - that's the waste pipe that takes the condensation from your boiler to your drain outside.
Your boiler will try and fire but cannot because the condensation has backed up in the boiler. The boiler will probably make a gurgling noise.
Try the steps below. You might need to repeat them a few times.
Identify the discharge pipe, this is usually a white plastic pipe that goes from the boiler to a drain or waste
Check that the drain/waste is clear of snow and ice
Hold a hot water bottle, or heat wrap, around the pipe, or pour hot, not boiling, water over the frozen end of the pipe with a watering can, jug or kettle. You might need to do this several times
(Do not put water on or in the flue)
If you think the pipe is unfrozen, try switching on the boiler again. You might need to reset it.
If the boiler fires up, it's fixed.
If it doesn't then pour hot water on the pipe again.
If your boiler pipes are still frozen, call our office to arrange for one of our engineers to unfreeze the pipe.
