You have a C-45 then. The C stands for compact. Since the chemicals require 20-25 psi to apply your final rinse chemicals to your wash items then your pressure sounds good. Booster heaters do not impact the wash quality. That comes from the dishwasher. A C-45 at 100 degree rise with 50 degrees incoming water temp will only put out 181 gallons per hour of 150 degrees water. Far from health code requirements. I suggest a preheater or connection made to your domestic hot water to comply with health standards.
