If there was an explosion it would probably be due to heating a
depressurised system and generating steam in a sealed system.

Well that is a different situation from a gas explosion... or late

Thanks as usual, John.

To clarify just this little bit, I was talking about the general explosion
risk if the boiler had not been modified (which as you say should be quite
low) as opposed to the minor gas explosion that they had which should be
another issue entirely (although worrying).
