❓ 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.
