the pressure to my hot water at my sink is nearly non exsistant and is not calling for hot water from the boiler. ihave to go to the shower(which is further from the boiler) to get it to kick start the hot water at the sink, the pressure not been that great at the shower either. the cold water pressue is fine,can anyone help with a soultion?

YEE I SUGEST DAT YE THE HEAT EXCHANGER IS BLOCKED WITH PROBERLY LIMESCALE N OTHER RUBBISH, THATS IT MATE, OR IF IT AINT FIRING WEN THE DEMAND IS ON THEN IT COULD BE UR PCB BUT CLEARLY THIS SOUNDS LIKE U NEED A NU HW HEAT EXCHANGER.

first port of call, there is a strainer type filter inline of the water water main to the boiler, isolate the water feed, open remove and clean the filter this maybe restricting the water flow and stopping the boiler from firing...

if not, the dhw heat exchanger could be sludged or scaled up....but do cheak the filer first
