Installing new/replacement pipework..where to start?

[mikegm]

City & Guilds Qualified at college a few years ago but no experience!!!
Just a hyperthetical question (at the moment) If I were to take on a house refurb/project and the central heating pipework needed replacing/updating, where (within the property) would I start, taking into cosideration a new boiler and hot water storage vessel being fitted. This was never really covered at College, so still baffled.

where do you think you should start ? think logically

If the pipework is copper it is unlikely is needs touching.
Only adjusting to match modern radiators and the like.

Similarly if installing a combi boiler it needs the old hot tank and header
tanks removing capping as necessary.

Start by trying to find a Gas Safe bod to sign off work other than what they do
