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?

Bring it indoors, connect to a drain for a sink etc. is best solution.

That just isn't feasible, I can't see that there is a route
available.

The soil stack is internal, in the external corner of the
kitchen, which has a solid floor, was recently refitted, and I
hope will see me out.

In any case, any route from boiler to soil pipe would also cross
the back door, so it is a complete non-starter.

If I were to consider for a moment pumping upwards, the bathroom
is above the kitchen, another expensive job I hope never to have
to disturb. Joists run perpendicular to the route, which is
covered by the rather large bath, as does the kitchen extractor
duct, completely blocking the route.
