How do I get rid of a hot water air lock?

Place your hand over the mixer tap’s end, then fully open the hot and cold taps, forcing the cold water mains up the hot feed pipe and pushing the air lock up into the tank to vent. Remove your hand from the mixer tap and turn off the cold water to see the hot water flow again.
