Viessmann Vitodens 100-W B1HG System Boiler

Viessmann Vitodens 100-W B1HG System Boiler

The Viessmann Vitodens 100-W B1HG System Boiler combines reliable heating performance with modern technology and an attractive price-to-performance ratio. Designed for homeowners looking for an efficient and dependable heating solution, this wall-mounted gas condensing boiler is built with quality components and straightforward controls for everyday convenience. The Vitodens 100-W B1HG is available in 19kW, 25kW and 32kW outputs, giving you flexibility when choosing a model to suit the heating requirements of your home. The right output will depend on the size and heat demand of your property, as well as the requirements of your heating and hot water system.

Efficient and Durable Performance

At the heart of the Vitodens 100-W B1HG is a stainless steel Inox-Radial heat exchanger, designed to provide efficient heat transfer while offering excellent durability. Stainless steel construction helps the heat exchanger withstand the demands of regular heating use, making it a reliable choice for long-term performance. The boiler offers standard efficiency of up to 98% (Hs) and has an Energy Efficiency Class A rating. It also features an energy-saving high-efficiency circulation pump, helping the heating system use energy more effectively during operation.

Flexible Modulation Range

With a modulation range of up to 1:10, the boiler can adjust its output according to the heating demand of the property. Rather than constantly operating at maximum output, it can reduce its power when less heat is required. This helps support efficient operation, reduce unnecessary cycling and maintain a more consistent level of comfort throughout the home.

Smart and Intuitive Boiler Controls

Operating the Vitodens 100-W B1HG is designed to be simple. The boiler features a detailed LCD touchscreen display with a clear menu structure, making it easy to access settings and manage your heating system. For added convenience, the integrated WiFi interface allows the boiler to connect to the ViCare app. This gives you the option to control your heating remotely, helping you manage temperatures and heating settings while also keeping an eye on energy use.

Modern Black Panel Design

The new boiler control platform features a discreet black panel visual design that gives the boiler a clean and contemporary appearance. The touchscreen interface is designed to keep important information easy to understand without making the controls feel complicated.

Heating System Protection and Control

The Vitodens 100-W B1HG includes heating system frost protection monitoring and functionality, helping protect the system during colder conditions. It can also provide convenient control of direct and mixed heating systems. When used with the appropriate EM-S1 extension, the boiler can also be used to control solar domestic hot water heating, providing additional flexibility for systems that incorporate solar technology.

Advanced MatriX-Plus Burner Technology

The boiler uses Viessmann's MatriX-Plus burner together with Lambda Pro combustion control to deliver efficient and clean combustion. The fully automatic Lambda Pro system can adapt to different gas types, helping maintain consistent combustion performance without requiring constant manual adjustment. This advanced combustion technology is designed to support permanently high efficiency while keeping emissions low.

Hydrogen and LPG Ready

The Vitodens 100-W B1HG is certified for use with natural gas containing up to 20% hydrogen, making it better prepared for evolving gas technologies and future energy requirements. The boiler is also LPG ready, and conversion does not require an additional conversion kit. This provides added flexibility for properties that use LPG as their fuel source.

Three Output Options

The Vitodens 100-W B1HG is available in 19kW, 25kW and 32kW variants. This range provides options for homes with different heating demands, from properties requiring a more modest heat output through to larger homes that need additional capacity. Selecting the correct output is important for achieving efficient and comfortable heating, so the boiler should be sized according to the property's individual heating requirements.
