I think you missed the invisible smilely on Andy's post...

I did!

Works well on oil rigs as well...

Yes.

My question was how much electrolytic "effect" can you get on a single
pass through it?

No idea..

From the point of view of the heating side, not really since it is a
single fill application. Yes the water will dump some scale, but once it
has done so it won't do it again.

Will it be sufficient to justify a £10-£20 outlay. Part of me thinks
it must be, otherwise they wouldn't fit them to top end boilers.
