Boiler not working in freezing temperatures?
If your boiler has stopped working in freezing temperatures, then there is a good chance that your condensate pipe has frozen. Luckily, this isn't a big problem and it can be easily resolved yourself without the need for an engineer. This page will provide you with all the information needed to help you defrost your condensate pipe
How do I know if the condensate pipe is frozen?
If part of your condensate pipework is outside and does freeze during a prolonged period of very cold weather, you might hear a gurgling noise coming from the boiler and if your boiler has a digital display, you may see an ‘EA’ error code too. There’s no need to worry if your condensate pipe freezes. You can usually thaw it safely without the need to call an installer or engineer.
What is a condensate pipe?
Condensing boilers require an additional pipe to be fitted to carry away waste water that forms as a result of the normal condensing process. This is called the condensate pipe, it is normally plastic and runs from the boiler to a household drainage system or soakaway outside.
Evidence of condensed water running through the condensate pipe is an indication that your boiler is working normally.
Minimising the risk of frozen condensate
Turn the heating control on the boiler to maximum
Install a drain cover to protect the pipe end
Insulate the external pipe work
