Viessmann Vitodens 050-W 25–35kW Combi Boiler

Viessmann Vitodens 050-W combi boiler

The Viessmann Vitodens 050-W is a compact wall-mounted gas condensing combi boiler designed to provide efficient central heating and domestic hot water from a single appliance. Available in 25kW, 30kW and 35kW combi outputs, it is suited to apartments, smaller homes and domestic heating modernisation projects.

The Vitodens 050-W combines Viessmann’s Inox-Radial stainless steel heat exchanger with a MatriX-Plus burner and Lambda Pro combustioncontrol for efficient and clean combustion. Viessmann lists the range with A-rated energy efficiency, natural gas/LPG compatibility and integrated WiFi on applicable versions.

25kW, 30kW and 35kW Options

The current Vitodens 050-W combi range provides several output options for different heating and domestic hot water requirements:

• 25kW combi
• 30kW combi
• 35kW combi

Viessmann’s current product guide lists rated heating outputs up to 19kW, 25kW and 32kW at 50/30°C for the relevant versions, while continuous domestic hot water outputs are 26.3kW, 30.9kW and 34.4kW respectively.

Efficient Gas Condensing Technology

The Vitodens 050-W uses a stainless steel Inox-Radial heat exchanger designed for durable and efficient heat transfer. Its MatriX-Plus burner works with Lambda Pro combustion control to automatically adapt combustion to gas conditions, supporting efficient operation and low emissions.

Viessmann specifies 92% ErP efficiency / Class A for the Vitodens 050-W range. The newer 35kW model was introduced with a heating output up to 32kW and DHW output up to 35kW.

Integrated Instantaneous Hot Water

Unlike a storage combi boiler, the Vitodens 050-W combi uses an integrated instantaneous water heater for domestic hot water. This provides hot water without requiring a separate hot water storage cylinder.

The DHW flow rates at a 35°C temperature rise are approximately:

• 25kW: 10.2 litres/minute
• 30kW: 12.2 litres/minute
• 35kW: 14.3 litres/minute

Compact Wall-Mounted Design

The Vitodens 050-W is designed for installations where space is important. The current technical data lists dimensions of approximately 400mm wide × 300mm deep × 700mm high, making it suitable for many apartment, house and replacement-boiler applications.

Viessmann also highlights the compact dimensions, low weight and quiet operation of the Vitodens 050-W.

Natural Gas and LPG

The Vitodens 050-W is tested and approved for natural gas and LPG according to EN 15502. Viessmann’s documentation states that no conversion kit is required for LPG for the applicable range. Installation must always comply with local gas regulations and the specific appliance requirements.

WiFi and ViCare Connectivity

Depending on the version, the Vitodens 050-W includes an integrated WiFi interface. This allows compatible heating systems to connect with Viessmann’s digital services and ViCare application for convenient monitoring and control.
