A water heater with a higher recovery rate will solve your problem. A GDHE-50 Vertex or any tankless unit will provide plenty of water to fill your jacuzzi tub. What you have is basically no better than a standard AO Smith, other than the powered anode. The installer of your jacuzzi tub should have realized this and installed a unit with a higher recovery rate or one that can supply continuous hot water. A 48 gallon tub will empty the hot water in the tank and dilute it with cold. Your current water heater just doesn’t have the capacity to keep up.
