Viessmann Vitodens 100-W Condensing System Boiler

Viessmann Vitodens 100-W System Boiler

The Vessmanni Vitodens 100-W Condensing System Boiler is a wall-mounted gas condensing boiler designed to provide efficient central heating for residential and suitable commercial applications.

Part of Viessmann’s established Vitodens range, the Vitodens 100-W combines compact installation dimensions with modern condensing technology, high-efficiency operation and flexible output options.

The system boiler range is available in different heating outputs, allowing installers and heating professionals to select a suitable model according to the requirements of the property and heating system.

High-Efficiency Gas Condensing Heating

The Vitodens 100-W uses gas condensing technology to recover additional heat from the combustion process.

Viessmann rates the Vitodens 100-W with an A energy efficiency class, while its current documentation highlights standard efficiency of up to 98% on the relevant gross calorific value basis.

This makes the boiler suitable for customers looking for an efficient modern gas central-heating solution.

Viessmann Vitodens 100-W System Boiler

The system version of the Vitodens 100-W is designed for sealed central-heating installations.

Unlike a combi boiler, a system boiler is designed to work with a separate domestic hot-water cylinder where stored hot water is required.

This makes the Vitodens 100-W system boiler particularly relevant for properties where an existing hot-water cylinder or separate domestic hot-water system is already installed.

Vitodens 100-W Output Options

The Vitodens 100-W system boiler is available in multiple output configurations.

Current Viessmann documentation lists system boiler heating output ranges including:

• 3.2–11.0kW
• 3.2–19.0kW
• 3.2–25.0kW
• 3.2–32.0kW

The corresponding 80/60°C output ranges are approximately 2.9–10.1kW, 2.9–17.5kW, 2.9–23.0kW and 2.9–29.3kW respectively.

The exact output should therefore be confirmed against the specific model selected before ordering.

Compact Wall-Mounted Boiler

The Vitodens 100-W has a compact wall-mounted design measuring approximately:

700mm high × 400mm wide × 360mm deep

for the current B1HG/B1HF range configurations.

Its compact dimensions make the boiler suitable for installations where available wall space needs to be used efficiently.

MatriX-Plus Burner Technology

The Vitodens 100-W incorporates Viessmann’s MatriX-Plus burner together with Lambda Pro combustion control.

Viessmann states that the Lambda Pro combustion controller is designed to maintain high efficiency and clean combustion by adapting combustion operation to the gas conditions.

This technology forms an important part of the Vitodens 100-W’s heating system design.

Lambda Pro Combustion Control

The Lambda Pro combustion control system helps the boiler adapt combustion to changing gas conditions.

This contributes to consistent combustion performance and helps support efficient operation.

Modulation Range

The current Vitodens 100-W documentation lists a modulation range of up to 1:10, allowing the burner output to adjust according to heating demand.

Modulation can help the boiler operate at an appropriate output instead of continually operating at maximum capacity.

Energy-Efficient Circulation Pump

The Vitodens 100-W incorporates an energy-saving high-efficiency circulation pump.

This supports efficient circulation of heated water through the central-heating system while helping reduce unnecessary electrical consumption.

Natural Gas and LPG Compatibility

Viessmann documentation confirms that Vitodens 100-W/111-W boilers are tested and approved for natural gas and LPG in accordance with EN 15502.

However, the precise gas configuration and permitted output can depend on the selected model and installation conditions.

Always confirm the exact gas type and conversion requirements before installation.

Central Heating Applications

The Vitodens 100-W system boiler can be used for suitable central-heating installations in:

• Detached houses
• Semi-detached homes
• Terraced houses
• Apartments
• New-build properties
• Boiler replacement projects
• Suitable commercial applications

Viessmann specifically positions the Vitodens 100-W for medium-sized homes and modernisation projects.

System Boiler vs Combi Boiler

The Vitodens 100-W range includes both system and combi configurations, but this EuroFuelSupply product page is specifically focused on the system boiler version.

A system boiler normally works with a separate hot-water cylinder, while the Vitodens 100-W combi version incorporates instantaneous domestic hot-water heating.

Choosing the correct configuration is therefore important when ordering.

Compact Boiler for Modernisation Projects

The Vitodens 100-W can be considered for boiler replacement and heating-system modernisation projects where a wall-mounted condensing gas boiler is required.

Its compact dimensions, multiple output options and modern combustion technology provide flexibility for suitable replacement installations.

Viessmann Vitodens 100-W Specifications

Specifications can vary by generation, model and market. The exact product variant supplied should always be matched against the current Viessmann technical documentation.

Is the Vitodens 100-W Suitable for a Replacement Boiler?

The Vitodens 100-W is designed for both new-build and modernisation applications.

Its compact wall-mounted design and range of heating outputs make it suitable for a variety of replacement and heating-system upgrade projects, subject to professional assessment of the existing system.
