What is a condensate pipe and how do you unfreeze it please?

On my boiler (a Vaillant) the condensate pipe coming out of the boiler is a push fit. With a container held underneath the boiler, simply pull off this pipe. The water which builds up in a small container in the boiler casing should flow out. This will allow the boiler to re-fire. I've cut the condensate pipe a few inches under the boiler and am collecting the water in a bucket. It comes in short bursts because of a siphonic action out of the container in the boiler, and should be a manageable amount which can be poured away each day. When the thaw comes, I will replace the output pipe aiming to get it better insulated particularly where it goes through the wall and outside.

the plastic pipe about 5/8" that leaves the boiler go s through the wall and connects to the nearest outside drain.
increase the size of the PIPE OVER THE EXISTING PIPE to about 1-1/4" when the weather breaks .


a couple of kettles of hot water ,or the use of a hair dryer
should thaw it out
