I have seen a bank of toilets in a hospital that were crossed in just that state ..was quite a spectacle haha

Common problem, fitting a mini expansion vessel on the cold before the boiler should sort it.

You can delay the flow switch in an ecotec, might cure the surge from kicking the boiler in...
