Quicker Hot Water with Viessmann Vitocell 300-V ZK06893 119-Gallon Indirect Water Heater

Need hotel-level hot water for big families or multi-bath homes, without the high energy bills? The Vitocell 300-V EVIB-119 (ZK06893) pairs a stainless-steel storage tank with a large, bottom-to-top stainless heat-exchange coil for fast, even reheats. Its removable soft-PET insulation keeps standby loss low and makes tight-room installs easier. AHRI-certified performance (up to a 413 GPH First Hour Rating) means consistent back-to-back showers, laundry, and dishwashing. And because the tank and coil are high-alloy stainless, no sacrificial anode is required, reducing maintenance over time.

Key Features

Save Energy With Ultra-Low Standby Loss

Thick, removable soft-PET insulation minimizes heat loss—validated at just 0.4 °F per hour—so stored water stays hot longer and fuel spend stays lower. Because the 119-gallon model’s jacket comes off in seconds, you can keep that insulation intact while maneuvering through tight doorways, then re-install it for maximum efficiency once in place. 

High-Volume Comfort, Back-to-Back

When everyone needs a shower, the EVIB-119 delivers: an AHRI First Hour Rating up to 413 GPH and a continuous draw of 301 GPH keep fixtures supplied without temperature “rollercoasters.” A large 18.3 ft² stainless coil that reaches the tank bottom heats evenly, so the usable hot water is a generous share of the tank volume. 

Hygienic Stainless Steel—No Anode Rods

The tank shell and heat-exchange coil are both high-alloy stainless steel for corrosion resistance and clean water contact. That construction eliminates sacrificial anode rods, avoiding replacement costs and helping maintain water quality over time. Stainless surfaces also resist scaling and flaking better than enamel options, supporting long-term efficiency. It’s durability you can set and forget.

Fast Recovery You Can Count On

With design coil flows up to 22 GPM and recovery tables listed at 194/176/158 °F boiler supply temperatures, the EVIB-119 reheats quickly to cover big, multi-fixture draws. Typical heat-up time from 50 °F to 140 °F is about 25 minutes at 194 °F supply, so you’re back at full capacity fast after heavy use.

Viessmann Vitocell 300-V EVIB-119 FAQ

How many bathrooms or people can the 119-gallon Vitocell 300-V support?

With a 413 GPH first hour rating and a 301 GPH continuous draw, the 119-gallon Vitocell 300-V is generally sized for larger households, multi-bath homes, or properties with heavy simultaneous hot water use. Think several full bathrooms running back-to-back showers along with laundry or a dishwasher. Exact sizing still depends on your home's peak-hour usage and should be confirmed against your actual fixture count.

How long does the Vitocell 300-V take to recover after heavy use?

At a 194°F boiler supply temperature, the Vitocell 300-V EVIB-119 typically reheats from 50°F to 140°F in about 25 minutes. Recovery slows somewhat at lower boiler supply temperatures (176°F or 158°F), which Viessmann also publishes recovery data for.

How energy efficient is the Vitocell 300-V's standby heat loss?

The tank loses heat at a rate of approximately 0.4°F per hour while idle, thanks to its removable soft-PET insulation jacket, meaning stored hot water stays usable for a long stretch between heating cycles, reducing how often the boiler needs to fire just to maintain temperature.

Do I need a boiler to use the Vitocell 300-V?

Yes. Because the Vitocell 300-V is indirect-fired, it depends entirely on hot water circulated from a boiler through its internal coil to heat the tank. Without a boiler or comparable external heat source already in place, this tank has no way to produce hot water on its own.

Can the Vitocell 300-V's insulation be removed for installation in tight spaces?

Yes. The soft-PET insulation jacket is designed to come off quickly, making it easier to maneuver the tank through narrow doorways, stairwells, or mechanical rooms before reinstalling the jacket once the tank is in place.
