Takes about 1-2 mins to produce hot water so when you're washing your hands half the time you turn off the tap before it even heats up.
PCB failed 6 months ago and cost £200 to replace just after the 3yr gaurantee.
Keeps producing an error code 133 (the manual says gas supply problem) but works ok when it is reset or switched off for a few minutes. This happens around 10-20 times per year so far. My inlaws have had a Valiant boiler for past 4 years with no probs at all and instant hot water.
