I own and occupy a double house and have decided to leave the other
apartment empty for a while. I want to turn off the gas hot water heater
for that apartment to save energy. Is it as simple as shutting off the gas
supply and draining the tank? Do I need to concern myself with the
igniter/pilot mechanism? Are there any other start up concerns?
Thanks for the advice!

All he should have to do is turn off the valve on the gas control
assembly, then relight the pilot when ready to go again.
all tanks these days are glass lined. its not a flawless coverage, and
cracks and such do occur. at most it slows tanks rusting out as does
the anode rod/s.
if the water is turned off any leak will be slow and less likely to do
draining a older tank will only cause it to fail faster, from rusting.
only a good idea if the building might freeze.
in such a case draining and blowing all lines clear of water and
antifreeze in all traps like sinks and toilet, along with totally
draining dishwashers and clothes washers is ssential
