Viessmann Vitodens 100-W B1KF-30 Specifications

The above figures are based on Viessmann’s current technical documentation for the B1KF-30.

High-Efficiency Condensing Technology

The Vitodens 100-W is designed around gas-condensing technology, helping recover additional heat from the combustion process when operating under suitable system conditions.

Viessmann lists the Vitodens 100-W as an A-rated boiler and states that the range can achieve standard efficiency of up to 98% based on Hs. The range also uses a modulation ratio of up to 1:10, helping the boiler adjust its output according to heating demand.

MatriX-Plus Burner and Lambda Pro

The Vitodens 100-W incorporates Viessmann’s MatriX-Plus burner together with Lambda Pro combustion control. These technologies are designed to maintain efficient combustion across changing operating conditions.

The Lambda Pro combustion control automatically adjusts the combustion process, while the MatriX-Plus burner is designed for efficient and clean gas combustion.

Domestic Hot Water Performance

The B1KF-30 is a combination boiler, meaning it provides domestic hot water directly without requiring a separate conventional hot water cylinder.

Viessmann specifies a continuous domestic hot water output of 30.0kW for the relevant B1KF-30 configuration. The manufacturer also lists a DHW flow rate of approximately 14 litres per minute at a 35°C temperature rise and 17.04 litres per minute at a 30K temperature rise.

Compact Wall-Mounted Design

The Vitodens 100-W has a compact wall-mounted design measuring approximately 700mm high, 400mm wide and 360mm deep for the B1KF-30 configuration.

This compact footprint makes the boiler suitable for installations where available wall space is limited, including residential replacement and modernisation projects.

Natural Gas and LPG

Viessmann’s technical documentation states that Vitodens 100-W boilers are tested and approved for natural gas and LPG in accordance with EN 15502.

The correct gas configuration should always be confirmed before ordering and installation.
