Viessmann Vitocell 300-V 119 Gallon Indirect Fired Domestic Water Heater - ZK06893

Keep Hot Water Ready 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 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 showers, laundry, and dishwashing—back-to-back. And because the tank and coil are high-alloy stainless, no sacrificial anode is required, reducing maintenance over time.

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. That design also helps serviceability down the road. Tested performance is listed to AHRI’s IWH-TS-1 standard, so the numbers you see reflect real-world conditions, not lab wish-casting.

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. Paired with a properly sized modulating boiler, you’ll feel steady, predictable hot water during peak times. Less waiting—more doing.

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.

Installer-Friendly Handling & Fast Setup

On arrival, the 119-gallon model ships with its soft-PET insulation in a separate carton, making the tank narrower and lighter to maneuver into mechanical rooms. Standard NPT tappings—1¼″ for domestic hot/cold, 1″ for coil, recirculation, and T&P—keep piping straightforward with common fittings. Adjustable feet help you level quickly on uneven floors. A supplied sensor-clamp with three channels makes attaching control sensors simple and secure.

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. Those published curves make pump and boiler sizing more predictable for your installer. The result: less guesswork, more hot water.

Ready For Recirculation & Multi-Tank “Battery” Jobs

A dedicated 1″ recirculation tapping supports constant-circulation domestic systems to reduce wait time at far fixtures. Need hotel-style volumes? The Vitocell 300-V platform supports multi-tank batteries—common headers let you bank two or three tanks for peak-demand sites. Viessmann publishes the piping sizes, draw rates, and standby values for these arrays so pros can design confidently. Scale up when life (or business) demands it.

Built To Play Nice With Modulating Boilers

The Vitocell 300-V is designed for low-temperature, modulating hydronic boilers and includes AHRI-certified ratings at 180 °F supply and 14 GPM coil flow. That alignment improves seasonal efficiency and comfort while protecting the tank coil. Working pressures are robust—up to 150 psig on the DHW side and 220 psig on the heat-exchanger side—so it integrates smoothly across high-output residential and light-commercial systems. Smart pairing, simpler commissioning.
