think i'm on the right track with this but i know i will get good advice (and abuse) from here!!)
suprima 50 and boilermate 2000 fitted, customer complains of no hot water SOME mornings, suprima has locked out, it will reset ok so i assume it is a circulation problem, (by morning everything has cooled and esets easy, heating is not on during the night but boiler is on constant to keep water temp up, so if it is going to lock out i'm thinking boiler is overheating so it must be sludge in system or faulty boiler pump, not heating pump as it is off and not water/divertor pump as no running water during he night, any comments??
