Viessmann Vitocell 300-V EVIB-79 Indirect Water Heater, 79 Gal

A 79-gallon single-coil stainless steel indirect water heater for larger households with heavy or simultaneous hot water use. Heated by a compatible boiler, it carries AHRI ratings of 345 GPH first hour and 269 GPH continuous draw, based on 169 MBH heating input.

Its large stainless coil runs toward the bottom of the tank, warming more of the stored volume evenly so outlet temperatures hold steady during back-to-back use. Stainless construction means no anode to replace, and PUR foam insulation keeps standby losses low. Multiple Vitocell tanks can be joined for bigger applications, and the tank is CSA Low Lead certified under NSF/ANSI 372.

The AHRI rating assumes 180°F boiler supply and 14 GPM heating flow. Both heating and domestic connections are 1 in. male NPT, and the domestic side is rated to 150 psi. The tank is 26-1/4 in. wide and 68-1/2 in. high, weighing 231 lb.
