How can I fix my combi boiler Ariston 28HE?
How can I stop my brand new boiler firing up every few minutes even when hot water is not requested. When i turn the heating on 30 degrees on the thermostat, the digital display goes from 65 to 57 then stops for a moment and it goes from 57 to 65 without stabilising. Is it a circulation problem?
