trace heating

[GQuigley67]

when installing trace heating, does it require its own fused switched spur ?

Apparently so. Did an outside combi last week and customer had discussed with electrician about trace heating condensate line. I put an extra sleeve through before I stoned up the old flue from the inside boiler just in case. When I spoke to the electrician he was on about an independant fused spur, but has he had changed the existing fused spur for an rcd spur he said he couldn't take the feed from the existing one because if the trace heating faulted it would trip the rcd and then the boilers frost protection would be compromised.

Yes it does , their is also no real need to install trace heating on outside conense line just increase bore of pipe to stop winter conditions taking effect .Overly expensive to install on condense line i would say.

Based on what? your 3 months training course experience?

Seeing as how full of info you are, what size would you increase it to and why would there be no need to install it. Surely site conditions would dictate? Please share your wealth of knowledge and experience.

Try reading my original reply, external combi, can't run it internally, funny that.

Funny you say 1 1/4", thats what manufacturers recommend and why I install 1 1/2".

ive got a customer whos condensate has frozen twice now, it has exited the building and runs almost horizontal into the RWP, I'm trying to figure out what would be the best and cheapest option for them, probably upgrading to 32mm with lagging will be the best

I insulated a 1 1/2" run last year. Had to special order the insulation, didn't carry it.

 

[GQuigley67]

what type of insulation did u use ??

 

[SimonG]

Just the standard and wrapped it with a roll of black electrical insulation tape (1" thick).
