Help stopping condensate pipe freezing this winter

[beddoe79 10]

Hi

 

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

last year home owners were disconnecting the out side pipe and rigging up a drain inside the house, easy cure.

Can you lag it with something that won't melt easily, like fibre glass or rockwool?

Thanks for the suggestions so far. Can anyone recommend anyone to do either the lagging?

This firm offers external insulation but don't know if you can get in local shops.:

I have had similar problems, installed trace heating, problem solved. Google condensate pipe trace heating, plenty of options.

Hi Thank you for all the suggestions, can anyone recommend anyone that can fit these. We do not have ladders that would allow us to get to the pipe so would need to someone to install either the lagging or the trace heating

It's only water vapour so it won't melt anything, normal foam lagging will work.

Normal foam lagging is polythene, with an approximate mpt of 120 Celsius.

Steam condensing to water vapour could easily soften that and degrade it over time.

The external pipe should be at least 32mm waste pipe (1.1/4") and lag it with this:https://www.bes.co.uk/boiler-condensate-pipe-insulation-355mm-x-25mm-x-2m-20926
