We have a condensate pipe coming from our boiler that goes all along the outside, just above a 1 storey extension and then drops into the guttering of the said extension. The boiler is situated in a bedroom.
Last year it froze all the way along and affected the central heating as it couldn't drain.
Has anyone got any ideas of how we can prevent this? We were told previously that we could lag the pipe then someone from localheros.com told us we couldn't. Any sensible ideas welcome, I can also provide a picture.
Thanks in advance
