What radiator pipes

boyesey · 10 Nov 2005

Most of my heating system is 22mm flow and return pipes with 8mm feeding each radiator.

What would be the effect of feeding some new radiators with 15mm pipe?

The new boiler is an Ideal Isar HE35 combi.

The effect would be that your radiator would work.

Try and come off the 22 mm pipes to feed your rads though. You can feed 2-3 rads off this 22 mm tee.
