New Build Advice First Fix

[A.Singh]

Hi,

I wanted to ask you guys for some advice. How would you advise to run radiator pipes in new build flats? The floors are all concrete, someone advised to run them in the floor before the screed goes in?

Your advice and help is appreciated.

Thanks

Hi & welcome.

I’d never advise anyone to lay pipes in concrete because if there are any issues how would you access the pipe.

You have 2 options

1. Surface mounted you run all the pipes along the walls and box them in.

2. Or you lay ducting in the concrete and run the pipes in that. Manthorpe Pipe and Cable Ducting 150mm x 70mm x 3m - Box of 10 | Drainage Superstore ®

However you should speak to the engineer that’s installing the heating system.

Run them in ducting under the screed. Do it in 10mm plastic have a manifold somewhere above ground then run in 1 continuous run to the rad so you have no joints under the floor.

Do they need to go in the floor could you do drops ?

 

[A.Singh]

Thanks for your replies. Ideally in the floor to make the job neat as possible. The ducting in the screed doesn’t sound like a bad option if it’s run around the perimeter of the rooms?

Drop from above
What are the walls made of?
How will you run the gas?

 

[A.Singh]

The walls are blocks but they are load bearing as there’s concrete floors.

Gas is going to run externally straight into the kitchens where the boilers will be.

So dot and dab plasterboard

 

[A.Singh]

Yes dot and dab.

 

[ShaunCorbs]

Yes dot and dab.

More than enough room down there for pipes as the sparks boxes will be off that much

If you go up and have drops you will have to have a false ceiling. The ceiling and adjoining walls will have to be fire rated so you cant have pipes sticking through everywhere.

This will have to be done anyway regardless of if there’s anything up there

The sites I've worked on haven't they just double boarded fire board on ceilings. No need for a false ceiling.

How did they fix it normally Battons to the ceiling

What the plasterboard? Either straight to the joists or yeah onto batons on the joists.

That doesn't get past the fact building control do not like pipes coming through causing holes into the fire protection. Not sure how electricians get round it but from past experiences your better off going down and up.

Won’t be a hole in the ceiling anywhere you can fire protect
