When old boiler has been removed, run mains pressure water through

Do this thoroughly and it will clear the system much better than
power flushing.

If you are doing as much flushing as you are, maybe rent something like:

Water-air mix pulsed through the pipes...

You can take it all apart, hire a pulsing job etc, but probably none of it's necessary. Just fit a filter and add some cleaner, and be prepared to every the filter several times.

I'd recommend a filter with a filter mesh, not just magnet, much more effective. About £45 new on ebay, I forget the brand.
