Hi all,
For various reasons, I want to replace the downstairs radiators on my
1970ish Y plan heating system, along with their plumbing. There are currently four large radiators downstairs. I'll be adding more when I get to work on an extension in the spring but, for now, I just want to replace those four rads.My current plan is to run "backbone" pipework in 22mm plastic from the controls in the airing cupboard, through the floor void to each of the rad positions. I'd do the drops from the backbone to the rads in 10mm plastic to make installation quicker and to keep the chase depth down to a minimum.
Does this sound like a really stupid thing to do? A quick look online seems to suggest that opinion is divided on plastic in general and 10mm in particular...
Cheers,
Colin.
