Heating the engine up then flushing cold water may sound good in practice but make sure you use warm/hot water when you flush it or the rapid hot/cold will crack/kill heads and gaskets....

Agreed, but that's not what I'm suggesting. Fill with water + bio degreaser, Fernox, Persil or whatever, drive it for a day or two, dump the coolant out once cool and repeat.

Then, once happy, dump the coolant out once cool, flush with a hose until the coolant runs clear, fill with water, bring it up to temperature to flush everything one final time, dump coolant once cold, top up with correct volume of anti-freeze plus water as required.

It is indeed a bad idea to introduce cold water to a hot engine.
