I have an aging ferroli Hawk II combi boiler and it has developed a fault. It had a loss of pressure, which it often does, but now I have refilled it no heating. The hot water is OK and the Pump is working but all that happens for heating is that the boiler fires for approx
30 seconds then goes off for 10 minutes and then repeats. The radiators are very slightly warm. Any help and ideas would be appreciated Thanks- posted
