AO Smith BTR-201 Master Fit Booster Water Heater (for dishwashers)

The Master-Fit BTR-151 and BTR-201 are designed for installation in booster applications, to supply commercial dishwashers with very high temperature water, typically 180ºF. A booster water heater is generally used in conjunction with a standard water heater delivering hot water at a lower temperature to meet the non-dishwashing needs of a restaurant or other food service application.

With a 32-gallon storage tank, these compact units measure only 45??” high, and hot and cold water connections can be made in the top, front, or rear for installation versatility.
