What is the differential setting on an aquastat?
When boiler temperature is rising: on an aquastat control, the “DIFF” or differential control dial specifies the amount above the LO or “Low Limit” to which boiler temperature must rise before the burner will turn off and the circulator will be allowed to run.

Will an airlock clear itself?
Airlocks do sometimes fix themselves, but it isn’t a risk worth taking. Airlocks occur when air becomes trapped in the hot water or central heating system. Vapour becomes caught in a high point of the pipework because the gas is less dense than the water in the system.
Can air get trapped in a boiler?
Air tends to get trapped in your radiators over time through small leaks, especially if you find yourself re-pressurising your boiler often. Or for older systems, you may find air came in through the pump above the supply pipe during installation or through the tank in your loft.
