Viessmann Classic BPKB Boiler
The Viessmann Classic BPKB is a compact combi boiler designed to provide both central heating and hot water from a single unit. With no need for a separate hot water cylinder or storage tank, it is a practical, space-saving option for smaller homes, apartments and properties where installation space is limited.
The Classic BPKB is available in 24kW and 28kW output options, allowing you to select the version that best matches the heating and hot water requirements of your property.
Combi Boiler Convenience
As a combination boiler, the Viessmann Classic BPKB heats water directly from the mains whenever hot water is required. This means there is no need to store hot water in a separate cylinder, helping save valuable space while providing hot water on demand.
The combination of central heating and domestic hot water in one compact appliance makes it a convenient choice for homes with limited space.
Efficient Viessmann Technology
Viessmann boilers are engineered with efficiency and reliable performance in mind. The condensing technology used across the Vitodens range is designed to recover heat that would otherwise be lost through the flue, helping make better use of the fuel consumed.
The boiler's modulating burner can adjust its output to match the heating demand of the property. Rather than operating continuously at full power, it can reduce its output when less heat is required, helping support efficient operation and consistent indoor temperatures.
Compact, Space-Saving Design
The compact design makes the Classic BPKB suitable for installations where space is at a premium. A combi boiler also eliminates the requirement for a separate hot water cylinder, potentially freeing up additional cupboard or storage space.
Vertical Flue Configuration
This model is supplied with a vertical flue arrangement, allowing combustion gases to be discharged through the roof rather than horizontally through an external wall. This can be particularly useful for installations in loft spaces or rooms where a suitable external wall is not available.
The vertical flue must be installed correctly and in accordance with the applicable regulations and manufacturer's requirements.
Weather Compensation
Compatible Viessmann systems can be paired with suitable external weather compensation controls. These sensors monitor the outdoor temperature and can allow the heating system to adjust its operation according to changing weather conditions, helping improve comfort and energy efficiency.
Quiet and Lower-Emission Operation
The Classic BPKB is designed for quiet operation, making it suitable for homes where reducing boiler noise is important. Its low-NOx design also helps limit nitrogen oxide emissions during operation.
Smart Connectivity
Compatible Viessmann systems can support smart connectivity through the ViCare app, allowing heating and hot water settings to be managed remotely from a smartphone when the appropriate compatible controls and connectivity are installed.
Available Output Options
The Viessmann Classic BPKB is available in two power ratings:
-
24kW – a suitable option for properties with lower heating and hot water requirements.
-
28kW – provides a higher output for homes requiring additional heating capacity and hot water performance.
The correct boiler output should be selected based on the property's heating requirements, hot water demand and overall system design.

Frequently Asked Questions
What output options are available for the Viessmann Classic BPKB?
The Viessmann Classic BPKB is available in 24kW and 28kW versions. The right output will depend on the property's heating requirements, hot water demand and overall system design.
Does the Viessmann Classic BPKB need a hot water cylinder?
No. As a combi boiler, the Classic BPKB heats domestic hot water directly from the mains when it is required. This removes the need for a separate hot water cylinder and can help save space.
What is the benefit of a vertical flue?
