Move or replace a boiler?

[Crowbar hero]

We have a Glow Worm Ultimate₂ 35C currently providing heating and hot water  - it's about 6 years old and is working fine.

It's current location is on and adjacent to a wall which we need to remove as part of our extension plans, I want to reposition the boiler in the extension. One of the plumbers I contacted is unenthusiastic about moving an 'old' boiler and would prefer to fit a new one - aside from the easier sequencing (less time without heat/water services in the house) is there much to be gained from replacing a decent older boiler for a brand spanking new one? 

I'd understand if it was a 20yr old something or another which could benefit from a more efficient replacement, but this is a modulating, eBus controlled device with another 10yrs + of life left in it (probably).

is this just  a reluctance to work with "someone else's" work, a desire to sell a boiler, or is there possibly some other reason I'm missing?

I guess it is just much less work to fit everything from new.

Our last house we moved a similar aged boiler and the plumber didn't even comment. 

 

If it working fine and suits your needs keep it, swop the plumber.

I appreciate there may be a fitting kit, with templates and such which is now log gone for the glow-worm, so there would be a bit more thinking involved.

It's tempting, however we're on a bit of a time crunch as my preferred plumber has put his back out, so I'm ringing around a few contacts trying to get someone to jump in at the last minute and do a job they probably won't enjoy or make a good margin on..

 

Your post implies you did some of it yourself - how did that go?

That job was all done by contractors, as I was working overseas at the time and my wife managed the house renovations.
