Eleanor, Air typically will rise to the highest point in the system and separates from the water easier as it is heated. Identifying how the air is getting into the system is important. There is always oxygen in water. I would recommend a good system air separator and possibly air vents at the high point in the system. If there is that much air in the system a good flush and fill followed up by air separation and vents should correct this.
