💧 Uninterrupted Domestic Hot Water Comfort (Conversion Psychology)

The central feature of the Vitodens 111-W is its ability to handle large demands for hot water.

Accumulation and High-Demand Production

• Integrated Storage Tank (46 liters): The stainless steel tank of 46 liters It ensures a large volume of hot water available at all times, ideal for simultaneous use at several points.

• Modulating Load System: Thanks to a precise outlet temperature probe, the modulating charging system ensures that the DHW temperature is maintained constant, eliminating annoying fluctuations.

• Reduced Production Times: The high-power charging system allows a high production of DHW and significantly reduces accumulator reheating times.

🛡️ Maximum Reliability and Technical Efficiency (EEAT: Authority)

Durability and low consumption are essential pillars of Viessmann technology.

Key Components with Warranty and High Performance

• Inox-Radial Heat Exchanger with 10 Years Warranty: The ten-year warranty on the stainless steel heat exchanger (owned by Viessmann) ensures the reliability and corrosion resistance in the long term. Its effect of self-cleaning maintains constant efficiency.

❓ Frequently Asked Questions

Technical Questions about the ACS Comfort of the Vitodens 111-W

What type of demand is the 46-liter storage tank ideal for?

The 46-liter storage tank is ideal for homes with medium to high domestic hot water demand where large flow rates are required in short periods of time, such as quickly filling a bathtub or using two showers simultaneously. It provides superior comfort compared to an instantaneous water heater.

How is an A+ energy rating achieved?

The boiler achieves an A+ energy rating for heating when installed in combination with a modulating thermostat (class VI) with an outdoor sensor or when integrated with a solar thermal collector system. These components enable ultra-efficient temperature management.

Is the integrated 46-liter storage tank sufficient for a large home?

The 46-liter storage tank is highly efficient, and its modulating filling system ensures rapid hot water replenishment. For households with exceptionally high demand or a large number of users, it's an excellent solution that outperforms instantaneous water heaters while maintaining a compact wall-mounted design.
