Vokera Compact Combi Boiler no central heating

Hi All,

I have a five years old Vokera compact combi boiler. My problem is quite complicated as I am getting the required hot water but there is no central heating. Moreover, heating works fine just for few seconds. I have tried to set the boiler’s thermostat but the problem persists. Has someone faced this issue? Please share your views

Thanks in Advance


Hi Wilson,

The problem could be due to various things ranging from limescale build & NTC thermistors to the badly stuck diverter valve. If there is no any major issue then, simply replacing a diverter valve will serve the purpose. However, it is better to seek help & advice from a professional boiler engineer to solve this issue in a better and wise manner.
