Worcester 350 DHW heat exchanger

[nv_london]

Assuming a basic amount of DIY skill/knowledge, but not being a professional or corgi registered etc, how difficult would it be to replace the water to water heat exchanger on a Worcester 350 combi boiler?

Looking at the manual, everything seems straight forward, the only bit I'm concerned about is having to remove the gas valve (there are instructions for this as well, but if professionals on here say that it's tricky etc, I'd rather not attempt it!).

Thanks for any suggestions!

Get a RGI to do it!!

All the professionals would say that removing and particularly replacing the gas valve should be done by a CORGI.

Many thanks for the prompt and no nonesense replies!

(Even though I'd love to try and fix it myself, I really don't want to bite off more than I can chew and have an even bigger problem at the end).
