worcester 24cdi rsf pressure low (did not know to keep at .8) when put on heating, boiler seemed to blow! turned off, all water out & we mopped up. we think we have blown heat exchanger, Is this likely? Can we still use hot water until repaired/replaced heat exchanger without damaging anything else?

You really ned to get it looked at. And no the HW wont work either. Rare the heat exchanger would blow, probs a joint leaking.
