The Winter Freeze

The Winter Freeze

Freezing condensing pipe (How to keep your boiler operating)
Every year the winter months seem to get colder, so it is important to maintain your pipes to help ensure your heating operates properly and you have no winter emergencies.

If you are worried your pipes are frozen check through these 3 of these statements, and if they are all true we will go on to explain what to do next:

1. The outside temperature is or has been below freezing
2. Your boiler is displaying either an EA fault code, a D5 code or is displaying a flashing blue light (for 26CDi boilers you may see a flashing red light instead)
3. Your boiler is a Greenstar gas boiler, or a 26 CDi
If all 3 statements are true, you should now try to reset your boiler. This can be done by holding in the ‘reset’ button (this can be found on the boiler control panel) for 10 seconds. Once you have released the button you should wait 2 to 3 minutes to see if the boiler re-fires
If the boiler does not re-fire and it is emitting a gurgling sound, then it is almost certain that your condensing pipe is frozen, you should proceed to check your condensing pipe.

The condensing pipe is a plastic pipe (black, white or grey), coming from the bottom of your boiler. If this pipe is less than 32mm in diameter and runs outside of the property or through a non-heated area then it should be fully insulated with waterproof lagging. If it is not fully lagged and the 3 criteria above apply then it is likely that it is frozen and needs to be thawed.
How can the condensate pipe be thawed?

Please note: You should practice extreme caution at all times when attempting to identify and thaw a condensing pipe, here is how to do it:
• You should only attempt to thaw a condensing pipe that is at ground level and which is easily accessible to you. Under no circumstances should you attempt to thaw a condensing pipe which is at height without the assistance of a professionally trained engineer

• Applying a conventional hot water bottle or heat wrap is a sensible and safe way of thawing the condense pipe. Simply hold the hot water bottle or warmed heat wrap around the condensate pipe to thaw it

• Once thawed, the boiler must be reset. This can be done by holding the reset button in for 10 seconds and then waiting 2 to 3 minutes for the boiler to re-fire
