Boiler pressure relief valve needs replacing and water runs hot to cold .Implications of the first and reason for latter?

the hot water issue may be the pressure or you may find that if this still happens when the pressure is correct then you need to look at the plate to plate heat exchanger being blocked , hope this helps , kind regards Graham

If the pressure relief valve is passing and the boiler is losing pressure then once the pressure drops by a certain amount the boiler won't function properly
