Hello folks,

How much (if any) buggering about is one allowed to do to one's own gas boiler?

The reason I ask is that my boiler fails to light most of the time during the winter months. Research indicates this is due to a build-up of ally (aluminium?) oxide on the heat exchanger.

Further reading suggests it's not a difficult procedure to carry out, assuming one is competent with a screwdriver etc, which I am. Obvious precautions like turning off the electricity supply and presumably the gas supply too would apply.

Thanks and regards to all.
Jon
