not mentioned thus far is that when you lite your hot water heater after not being used for awhile one should always check the relief valve on the hot water heater to make sure all air is purged. If no water comes out your tank is empty. DO NOT TURN THE HEATER ON. If this is the case.
Actually .....NOT the T&P but open a faucet Hotside so air is bleed out of hotside/Water heater fills to correct water level and maintains the AIR POCKET that helps control pressure increases when heating water
Opening the T&P can disrupt the formation of that air pocket
