The Rheem GX X-Treme ASME natural gas water heater delivers extreme BTU input with ASME Boiler and Pressure Vessel Code certification for large-scale commercial and institutional facilities where both maximum heating capacity and pressure vessel compliance are required. With its massive heating capability and certified construction, the GX X-Treme ASME is specified for the most demanding hot water applications where standard commercial units fall short.

The Rheem GX X-Treme natural gas water heater is designed for large commercial and institutional applications requiring maximum BTU input and exceptional recovery capacity in a non-ASME configuration.
