Central heating pipes in attic - Advice

[Sealey]

Hi,

I am in the process of putting in central heating into a 70s bungalow and I am going to do some of the work myself as my mate who's a plumber is finding hard to start on the job due to personal problems.

Anyway, I was just wandering if the feed and return pipes that will run in the attic can be placed into clips and run across the beams or do they really need to run in notches, so that they are below top height of the beams.

The attic is of limited height and I have no plans of putting anything up there so from my point of view it would be much better if they ran on top of the beams.

Any advice would be greatly appreciated.

Thanks.

Run on top of ceiling joists, keeping runs as smooth a grade as possible, provide at least one air vent on flow and one on return at the high point of pipework. Insulate pipes individually and when replacing roof insulation lay the bulk of insulation above pipes.( insulation that runs between ceiling joists can be left in place). Screw crawl boards in place to assist access and leave in place for future maintenance. Do not nail as nailing will disturb plaster ceiling.
Do not use automatic air vents, as dependant on pump position, one of the air vents could suck air.

Do Not notch the beams (rafters) in lofts !!!

As above
Clip along the tops with a spacer so that you can get the required thickness of pipe insulation around them even as it crosses them.
