Can someone please help. I have the above combi-boiler and recently the timer for the central heating has started to run very slowly. Sometimes I need to adjust by up to 2 hours per day so that the heating will kick in on the timer. can I buy a new timer for this model and will it be easy to fit,many thanks arty1956

hi mate if the timer is internal to the boiler, then you can get a new one from heating replacement spares (h.r.p.c) or if its external timer take the model number an name off it an can get a replacement from the same place
