Streamline Your Hot Water With Viessmann Vitocell 300-V 53-Gallon Indirect Water Heater

Outfit your home for abundant, hygienic hot water with lower standby losses. The Viessmann Vitocell 300-V EVIB-53 (7720343) is a 53-gallon indirect-fired domestic water heater designed to deliver abundant, consistent hot water using heat from an external boiler. Its high-grade stainless steel tank and large heat exchanger coil provide fast, even recovery while resisting corrosion for long-term performance. With low standby heat loss and no sacrificial anode to replace, it's a dependable, low-maintenance choice for residential hot water systems.

Key Features

Fast, Even Hot Water Recovery

The large stainless steel coil extends toward the bottom of the tank to heat more of the stored water evenly, helping maintain consistent temperatures through repeated hot water demand.

High-Grade Stainless Steel

The tank and heat exchanger use corrosion-resistant stainless steel for long service life and hygienic domestic water storage. The design also eliminates the need for a consumable sacrificial anode.

Low Standby Heat Loss

Efficient PUR foam insulation helps retain stored heat between draws, reducing standby losses and helping the system use boiler energy more effectively.

More Capacity Without More Appliances

The 53-gallon tank stores a substantial reserve of hot water while using an existing compatible boiler as its heat source. Multiple Vitocell tanks can also be combined when an application requires greater hot water capacity.

Vitocell 300-V FAQ

How does the Viessmann Vitocell 300-V work?

The Vitocell 300-V uses hot heating water from an external boiler to heat domestic water through its internal stainless steel heat exchanger coil. The heated water is stored in the tank, allowing the boiler to provide domestic hot water without a separate direct-fired water heater.

How much hot water can the Vitocell 300-V EVIB-53 produce?

The EVIB-53 has 53 gallons of storage, a 238 GPH first-hour rating and a 190 GPH continuous draw rating under AHRI-certified conditions. Actual recovery depends on boiler output, heating water temperature and the flow supplied to the tank coil.

How do I know if a 53-gallon indirect water heater is the right size?

A 53-gallon indirect water heater should be selected based on peak hot water demand, recovery requirements and available boiler capacity rather than storage volume alone. The EVIB-53 is a good step up from the 42-gallon model when a home needs more stored capacity or higher first-hour performance.

What size boiler does the Vitocell 300-V EVIB-53 require?

There isn't one universal boiler size for the EVIB-53 because the required boiler output depends on the desired recovery rate and heating water temperature. Its AHRI-certified rating uses 119 MBH heating input, 180°F boiler supply water and 14 GPM heating flow.

What maintenance does the Vitocell 300-V EVIB-53 require?

The EVIB-53 is designed for low-maintenance operation because its stainless steel construction eliminates the need for a consumable anode. Routine inspection and service should still follow Viessmann's installation and service instructions, including inspection of the temperature and pressure relief valve.
