Vitodens 200W Commercial Gas Boiler

The Vitodens 200-W is a wall hung gas condensing boiler for commercial applications available in 49, 60, 80, 99, 120 & 150kW models.

The Vitodens 200-W high output gas condensing boiler is one of the most efficient and reliable boilers for commercial use. Exceptional performance and careful design combine to offer maximum flexibility, whilst a range of advanced features and functions make installation, fault-finding and servicing easy.

Intelligent Lambda Pro combustion control system for optimum efficiency and performance

The Lambda Pro combustion control is designed to work efficiently irrespective of gas quality – a factor which will become increasingly important as international gas supplies become less reliable. The Lambda Pro combustion controller works alongside the burner to constantly monitor the air to gas ratio. Instead of the gas/air mix remaining fixed from commissioning, the mix is self-adjusting as required, to maintain optimum boiler efficiency in relation to the gas quantity – in a similar way to the fuel management system in a car engine. The control also replaces the traditional gas valve control and changing to LPG takes just a few seconds – with no changing of any parts.

Modulating MatriX pre-mix burner

Developed by Viessmann, the stainless steel MatriX pre-mix burner, burns with thousands of tiny flames instead of one large one, distributing heat cleanly and efficiently to the heat exchanger. With a modulation range of 1:5 the heat demand is optimised and maximum efficiency levels are achieved. The extremely low NOx and CO emissions meet and exceed all national clean air regulations and guidelines. The stainless steel MatriX mesh ensures long term reliability.

Advanced controls

The Vitodens 200-W is equipped with features and functions to make installation, maintenance and servicing easy. These include in-built software for remote data communication and monitoring, additional heating circuits, a solar/heat pump interface, safety monitor sensors and automatic commissioning functions.

Comprehensive warranties for complete assurance

The Vitodens 200-W comes with a 2 year comprehensive warranty as standard, and the option for a 5 year comprehensive warranty if fitted by a Viessmann Trained Installer.

The Vitocrossal range, from 80 to 1000 kW, offers a perfect solution for every application – from heating apartment buildings and public or commercial premises, through to generating heat in local heating networks.

Advanced condensing technology makes the Vitocrossal an effective and economical condensing boiler for many different applications. With an output range from 87 to 1400 kW, the Vitocrossal family can be deployed in larger residential settings such as heating apartment buildings through to public or commercial premises and generating heat in local heating networks.

Vitocrossal gas condensing boilers boast a range of features including advanced condensing technology, convenient control units, exceptional efficiency and low emissions.

Our Vitocrossal boilers are designed with both current and future needs in mind and as a result not only comply with current environmental legislation, but will continue to do so long into the future, even as emissions limits become stricter.

The stainless steel Inox-Crossal heat exchanger provides ideal conditions for utilising condensing technology. This smooth stainless steel heat exchanger lets the condensate created by the condensing process simply run off downwards. This creates a permanent self-cleaning effect, thus ensuring that the condensing technology is utilised at a consistently high level, resulting in a longer service life and reducing maintenance requirements.

Vitocrossal gas condensing boilers can be equipped at the factory with a MatriX radiant burner or vMatriX cylinder burner, and the Vitocrossal 200 (type CRU) with a MatriX disc burner.

The highly effective heat transfer and the high condensation rate enable standard seasonal efficiency [to DIN] of up to 98% (Hs) [gross cv] to be achieved. These high levels of standard seasonal efficiency are the result of the countercurrent principle related to hot gas and boiler water, along with intensive turbulation of the hot gases as they pass through the heat exchanger.
