Draining UFH pipes.

[Jenni]

Hello. 

 

I had rather optimistically hoped to have heating connected before the weather turned, but that hasn't happened.

 

So to remove risk of freezing, and worrying, I think it would be a good idea to get the water out of my ufh pipes. 

 

Can anyone advise how to do this please? Pipes are connected to a manifold, I have access to workshop air compressor but don't want to damage anything by just blowing air down without knowing a bit more. 

 

Thank you.

Air will be fine, set the line pressure to 15psi (1bar) and you won't damage anything, this is the typical system pressure when in use.

That's good info, thank you.
