My Mothers boiler seems to work OK apart from the mechanical clock which has started malfunctioning. I set the correct time and when I look at it a few days later it can be a few hours out. Its 5 years old, any suggestions on DIY.

install a wired/wireless prog stat, whichever is appropriate, if your ok with electrics it will be quite a simple job. you can leave the built in time control on constantly then and control on and offs from the new stat 
Hope you get a reply for that, most don't do a a thanks would be nice would'nt the world be better?

Many thanks for your reply. I hadn't thought of a wired/wireless prog stat. Have you any in mind? Any views on why the mechanical clock keeps going a few hours out. There haven't been any power cuts, is it a common fault with these. Im wondering if the clock can be repaired or replaced easier than fitting the above.
At the moment the mechanical clock is set to the always on position and the boiler is turned on using the wall stat. Are these wired programme stats just connected into the wall stat without having to remove the boiler cover i.e. in parallel with the wall stat switch. Ive been googling but I cant find any
there's nothing difficult in wiring this in if your are reasonably competent at electrics, honeywells are the make of prog room stats i use, as they are pretty user freindly, the mechanical clock can be unplugged and discarded if you use a prog room stat, and as for do the clocks commonly have problems, sorry to say it but anything associated with an ariston will have frequent problems.
Ok thanks, I googled and found this one which would seem to be the most basic. http://www.discountedheating.co.uk/..._Hour_Programmable_Room_Thermostat_CM901.html
