Viessmann Vitodens 050-W B0KA Combi Boiler

Viessmann Vitodens 050-W B0KA Combi Boiler

The Viessmann Vitodens 050-W B0KA is a compact, wall-mounted gas condensing combi boiler designed to deliver reliable heating and hot water without taking up unnecessary space. Its slim design makes it particularly well suited to homes where installation space is limited, including installations where the boiler needs to fit inside a kitchen cupboard. The B0KA is available in 25kW and 35kW output options, giving homeowners and installers a choice of power levels to suit different heating and hot water requirements.

Efficient Gas Condensing Technology

The Vitodens 050-W B0KA combines Viessmann's MatriX-Plus burner with the durable Inox-Radial stainless steel heat exchanger. Together, these components are designed to provide efficient combustion, reliable heat transfer and long-term performance. With an ERP efficiency rating of 92% and an A energy efficiency class, the boiler is designed to make effective use of fuel while helping to keep energy consumption under control. Its modulation range of up to 1:8 allows the boiler to adjust its output according to demand, helping maintain comfortable temperatures while avoiding unnecessary cycling.

Compact Design for Flexible Installation

Measuring just 700mm high and 300mm deep, the Vitodens 050-W B0KA is designed with space-saving installation in mind. Its compact dimensions mean it can be installed in a kitchen cupboard where suitable, while its low installation height can also make replacing an older boiler more straightforward. Low operating noise further enhances its suitability for installation within or close to living areas.

LPG Compatible

The Vitodens 050-W B0KA is LPG compatible, giving it greater flexibility for properties where LPG is the available fuel source. Conversion can be carried out without requiring an additional conversion kit.

Smart WiFi and Easy Controls

The boiler features integrated WiFi, allowing homeowners to connect compatible smart controls and manage their heating and domestic hot water through the ViCare App. The system can be commissioned using the Vitoguide App, while the ViCare App provides convenient control of heating and hot water programmes. The boiler itself features a user-friendly touchscreen control with touch buttons and a clear information display. Its discreet black-panel design provides a modern appearance that fits neatly into contemporary homes.

Reliable Combustion Control

The MatriX-Plus burner works alongside Lambda Pro combustion control to automatically adapt combustion to the gas being used. This helps maintain efficient operation and supports low emissions while providing consistent boiler performance.

Available Output Options

The Viessmann Vitodens 050-W B0KA is available in the following variants:

• 25kW – suitable for homes requiring a lower heating and hot water output.
• 35kW – provides a higher output for properties with greater heating and domestic hot water demands.

Choosing the correct output should take into account the property's heating requirements, hot water demand and the overall heating system design.
