Hi all,
The central heating pipework in my house is mostly in 15mm but the final spur to each radiator is in small bore (10mm or 7mm) - typically for the last 5' or so of pipe running from a stepdown T or elbow joint. I'm pretty certain there's no manifold, so not a true microbore system. Firstly I'm wondering if anyone has any ideas why it might have been done this way.
I had the boiler replaced about 5 years ago with a Potterton Suprima 100L and at the same time the heating guy installed several new rads on normal 15mm pipework. Because we've had some problems with corrosion, (pump probs because it was full of bits of rusted metal and other cack), I'm thinking of replacing all the small bore pipework, (and old rads if necessary), before next winter. My question is am I likely to cause more problems with the wider bore pipes, and will the boiler be powerful enough for the job.
Boiler is on 1st floor, fully pumped, open vented system. The area is about 2000 sq ft, over 3 floors, and there are 14 rads, (some quite large), and 2 towel rails.
Any ideas gratefully received - thanks
