I have a jackson Low Temp single door model.. I have an 80 gallon hot water heater but always run out of hot water... Is an 80 gallon machine big enough? The spec manual says the machine uses 1.5 gal per cycle...even based on the make up water coming in cold...I would think this would be enough. I am consodering a booster...but if i can;t keep enough water hot enough .,..the booster wonl;t help...any ideas? what do pewople use to make hot water?
