Viessmann Vitocell 100-B CVBC 300L Bivalent Solar Water Heater (Vitopearlwhite)

The Viessmann Vitocell 100-B CVBC 300-liter bivalent indirect cylinder (Manufacturer Part No. 7097564) is an high-efficiency domestic hot water (DHW) heating solution engineered for dual-energy systems. Equipped with two internal heating coils, it seamlessly integrates solar thermal collectors with auxiliary heating systems such as gas boilers, biomass units, or heat pumps.

Key Features & Benefits

Bivalent Dual-Coil Design: The lower solar coil efficiently harnesses thermal energy across the entire water volume, while the upper auxiliary coil tops up temperature on demand.
Superior Ceraprotect Enameling: Heavy-duty internal steel tank coating paired with a protective magnesium anode for long-lasting corrosion defense.
ErP Class B Energy Efficiency: High-grade rigid polyurethane foam insulation limits standby heat losses to just 65 W.
Vitopearlwhite Premium Finish: Sleek, modern aesthetic suitable for clean technical utility rooms.
Easy Inspection & Serviceability: Features a front inspection opening for straightforward maintenance and descaling.
