Hello everyone,
I've been slowly putting right a botched heating install at my cousin's place. One of the last jobs is to lag the pipes. The combi is in the loft, with a lot of exposed pipework, both copper and plastic (speed fit type). The pipes are 15 and 10 mm.
So far I have lagged the cold water feed to the boiler. I've used the foam type lagging.
Firstly, there are a couple of points on this pipe which I could not lag - the push fit joints (copper to push fit) and also the final few inches where the pipe goes into the boiler's underside - the pipe is too close to the wall and other pipes. Should these small sections be lagged? If so, how?
My second question is, should I lag the reamaining pipes? Specifically, its the flow and return CH pipes and the domestic water supply pipes. They are plastic.
I'm considering putting an extra layer of loft insulation down, which will effectively lag the pipes at the same time as they'd be covered. Sorry for the dumb question, but would there be a fire risk? I've noticed that the CH pipes get REALLY hot, so was unsure about having they sandwiched in loft insulation.
Any advice would be greatly received as I cannot find anything in the wiki / faqs or even google.
Many thanks,
KC
