Hi,
I have an 18 month old Potterton Promax HE combi boiler with a Grasslin mechanical timer. Since the heating season started the timer has been sticking. Not a problem until recently but now it's turned cold I don't know if I'm coming home to a cold house. Given its age, it only functioned reliably for one winter. Are this type of timer generally quite unreliable and if so are the digital type preferable. The like for like replacements are under twenty quid on Ebay, but it'll be a false economy if they commonly fail in this way.
