pipework replacement - good/bad idea?

[woodenhousejen]

Hi,

I am upgrading a house (wooden frame, wooden clad, brick base - old forestry style).

The plumbing and heating needs replaced (currently electric emersion and open fire back boiler).

The pipe work that is in is 8mm external diameter.

I know the current trend is to increase the bore of pipe work.

Would it be worth the time and financial investment to replace the small bore I currently have with an increased pipe bore?

Any advice and/or peoples thoughts about this would be greatly appreciated.

PS not sure of the lingo so if the above is unclear please ask for more detail....

It is probably junked up so if you are doing a major overhaul worth while. By the time you butcher it about to alter it, it would of been easier and quicker to fit whole new system.
