15 year old worcester 240 RSF combi boiler has developed problem. When i switch boiler to hot water only the central heating radiators heat up as well i think it may be the diverter valve, any ideas? and when central heating sysyem is switched on we have hot water from hot tap, but when boiler switched to hot water only the hot water tap is only luke warm any ideas what problem may be?
If it is deverter valve how much to replace and how to fit the valve any information welcome
Cheers
