    I have a Worcester Bosch Highflow 400 Boiler. On Saturday night my partner topped up the boiler from 0.5 to 1 & since we have had no heating but still have hot water. When I turn the thermostat on it is not calling for the heating - well the demand light doesn't come on the boiler. Can anyone advise please before I commit murder!

    (The pump is still running perfectly fine)
