I own a catering business and have moved into a new facility and need some advise. I need to run two commercial dishwashers and occasionally simultaneously and not run out of hot water. They both require about 1 gallon per cycle and run about a 1 minute cycle. Typically only one washer is running at a time. Natural gas is available but no 3 phase power. Which direction should I go to accomplish not running out of water. For a commercial tank size and BTU's?
I've looked into a gas booster heater $3k +, but still run into the issue of needing to feed it 120+ degree hot water.
I've had people tell me on demand hot water system would work best, boosters are the way to go, as well as commercial tanks will take care of me. Help! I'm sick of scrubbing dishes!
