HI AS SOON AS I TURN MY BOILER ON THE CH COMES ON EVEN WHEN I ONLY HAVE IT SET FOR HOT WATER. ALSO WHEN I HAVE IT ON TIMER WHEN IT IS SUPPOSED YO SWITCH OFF IT STOPS ON , AND WHEN I SELECT OFF ON THE TIMER IT JUST STOPS ON. DOES ANYONE HAVE ANY IDEAS
well pete-is-a-p*ss-poor-plumber, it is probably the PCB - Printed Circuit Board- and should cost about £150-£200ish ALL IN... or could be the diverter valve - which costs a LOT less.

Sounds like a problem with the timer or the wiring of it
