[redturnerburner]

hi all
can someone help me ,ive got to put a radiator in a big conservitory but the house has 10mm copper pipe ,can i make it up to 15 mm copper pipe for this rad and then reduce it back down to 10mm to join the old system ive got the 10 mm pipe and fittings but would the new rad work better ,or should i stick to 10 mm pipe all the way !
cheers

the old pipe work could be 15mm or 22mm and just 10mm to the rads so you could use any size pipe but if its 10mm even under the floor then i would use 10mm all the way. but its up to you you have to join the pipes so you can put a reducer in to step up the pipes up to 15mm and stick with that for the new rad

hope this helps
