we have an old warehouse on three floors with a tank recirculating hot Water circuit, during summer when the heating was off there were no issues, now the heating is on it airlocks daily & we have to run it off to drag the air out.
All the pipes run in the ceiling above tiles, the pipes aren’t lagged.
Any idea what could be causing it???
