Hi ltruong,
Welcome to the AGL Community!
On your most recent bill, is there a mention of a 'Controlled Load 1'? If so, you may have the option of upgrading to Controlled Load 2 which'll provide you with more hot water. You can find more information here: During which hours is the 'Controlled Load' switched on?
Cheers,
Jayden
