Viessmann Vitodens 100-W B1GA Heat Only Boiler

Viessmann Vitodens 100-W B1GA Heat Only Boiler

The Viessmann Vitodens 100-W B1GA Heat Only Boiler is a compact, wall-mounted gas condensing boiler designed to deliver reliable and efficient heating without taking up unnecessary space. With a choice of five output options, it can suit a variety of properties, from smaller homes and flats to larger homes with more demanding heating requirements. Available in 11kW, 16kW, 19kW, 25kW and 32kW outputs, the Vitodens 100-W B1GA provides flexibility when choosing the right boiler for your heating system. As a heat-only boiler, it is particularly well suited to traditional heating setups that use a separate hot water cylinder.

Efficient Heat-Only Boiler

The Vitodens 100-W B1GA is a regular, or heat-only, boiler that can be used with either open-vented or sealed heating systems. It is designed to work alongside a separate hot water cylinder, making it a practical replacement for older regular boilers where the existing heating system needs to be retained. Its gas condensing technology is designed to make efficient use of the energy generated during combustion. This can help reduce wasted energy and support lower heating costs while providing dependable warmth throughout the home.

Five Output Options

The Vitodens 100-W B1GA is available in 11kW, 16kW, 19kW, 25kW and 32kW variants. This broad choice makes it easier to select an output that matches the heating requirements of your property. The lower-output 11kW and 16kW models can be well suited to smaller homes, flats and properties with lower heating demands, while the 19kW, 25kW and 32kW versions provide additional heating capacity for properties requiring more output. The correct size should always be selected based on the property's heat-loss calculation and the requirements of the existing heating system.

High-Efficiency MatriX-Plus Burner

At the heart of the Vitodens 100-W is a high-efficiency MatriX-Plus burner, designed to provide clean, stable and efficient combustion. Combined with the boiler's condensing technology, it helps the system make effective use of fuel while maintaining consistent heating performance.

Durable Inox-Radial Heat Exchanger

The boiler features Viessmann's stainless steel Inox-Radial heat exchanger, which is designed for efficient heat transfer and long-term durability. Stainless steel construction provides a robust solution for everyday heating, helping the boiler deliver reliable performance over its working life.

Wide Modulation Range

The Vitodens 100-W can adjust its heating output to better match the demand from your property. This wide modulation capability allows the boiler to operate at a lower output when full power is not required, helping to improve efficiency and maintain a more consistent indoor temperature. It can also contribute to quieter operation and help reduce unnecessary cycling, making the heating system more comfortable and efficient during everyday use.

Hydrogen-Ready Technology

The Vitodens 100-W B1GA is compatible with gas containing up to a 20% hydrogen blend. This provides a degree of future-readiness as the energy industry explores lower-carbon gas alternatives.

Built-In WiFi and ViCare App

Integrated WiFi makes it possible to connect the boiler to the ViCare app for convenient smart heating control. From a compatible smart device, homeowners can adjust temperatures, manage heating schedules and monitor the system remotely. The boiler can also work with Viessmann smart thermostats and a range of compatible third-party controls, giving you flexibility when setting up your heating controls.

Smart Diagnostics and Monitoring

The Vitodens 100-W includes intelligent diagnostic features designed to help identify faults and provide useful information for servicing. This can make it easier to understand potential issues and support quicker troubleshooting when the system requires attention.

Simple LCD Controls

An easy-to-use LCD display provides straightforward access to the boiler's settings and controls. Combined with its smart connectivity options, the system gives homeowners both simple local operation and the convenience of remote heating management.

Compact Design for Flexible Installation

The wall-mounted design keeps the boiler compact, making it suitable for installation in smaller cupboards, utility areas and other spaces where room is limited. Its compact construction can also make it a practical replacement for an older regular boiler, particularly when retaining an existing heating system.

Reliable Heating for Traditional Systems

As a heat-only boiler, the Vitodens 100-W B1GA is designed for properties that use a separate hot water cylinder. This makes it a suitable option for replacing older regular boilers without necessarily having to change the entire heating and hot water arrangement. With its combination of efficient combustion, durable components, smart connectivity and a choice of five outputs, the Vitodens 100-W B1GA provides a versatile heating solution for a wide range of homes.
