Mixed Systems

[Bearnie]

I think I already know the answer to this question but would value your answers just the same. We have a conventional central heating system in the house - 15 & 22mm pipework and a combination boiler. We need to fit 2 extra radiators to the system, however, the pipe work is going to be a nightmare to install due to accessibility problems. I could use plastic pipe, using its flexibility to bend round the awkward bits, but prefer copper which would be almost impossible due to the already mentioned accessibility problems. My question is, could I fit these 2 radiators using a small bore system connected to the original system? It would solve my fitting problems, use less joints and allow me to use copper pipe.
Your thoughts please.

I assume what you mean is 'microbore' as the pipes you already have are small bore.

Can't see any reasons why not too, but the existing rads will need to be balanced down more to let the flow go to the new ones better.

Dave, thanks for your input, it's very much appreciated. You're quite right I did mean microbore.
Thanks again.
