Getting closer to deciding to add trace heating to my condensate
drain.

As I had freezing problems, last year I lagged the external
pipework with 25 mm thickness Armaflex. The extreme weather last
winter still caused me some problems, at the junction with the
downpipe.

Looks like I need self-regulating heater tape + thermostat +
additional lagging over the junction with the rectangular
downpipe.

As it is a rainwater downpipe, it is open at the top. Am I
wasting my time (or money) trying to heat the bottom of this?
Should I just try to ensure that the actual waste pipe is heated

I can find some suitable parts at TLC, and a few specialist
suppliers.

Can anybody recommend a good value kit for the job?

Where would I find off cuts of sheet Armaflex at a reasonable
price?


Condidering my downpipe froze solid last winter you would probably need to
heat it to the bottom.
