Wall-mounted condensing boiler for heating with natural gas (propane) with flue gas discharge through the wall, roof, or a shaft or skylight.

New generation condensing technology
The ecoTEC exclusive gas boiler offers condensing technology with many intelligent functions in a modern design. The compact wall-mounted device is specially designed for use in single-family homes and represents an investment in the future, whether it is a new building or the modernization of your old heating system.

Be prepared for possible fluctuations in the gas composition
The heart of the new generation of ecoTEC exclusive boilers is the intelligent IoniDetect combustion control. Since the system automatically detects the different types and properties of gas, the combustion system optimizes itself for maximum energy yield. So you don't have to worry if the composition of the supplied gas changes in the future, your boiler will automatically adapt.

Awarded the Green iQ label for future technology
The ecoTEC exclusive gas boiler is an investment in ecological heating. It carries our Green iQ label, which represents the highest demands for sustainable technology and smart connectivity. All Green iQ products can be connected via WLAN and, thanks to compatible technical interfaces, can be conveniently operated on the go using smartphones or tablets.

The Green iQ brand also stands for resource-saving production and the use of high-quality recyclable materials from carefully controlled sources.

Design for intuitive operation
The attractive design of the new ecoTEC exclusive boiler will catch your eye at first sight. Its clean, clear lines and illuminated black-and-white display are a sign of a new era for gas condensing boilers.

Not only does it integrate perfectly into your home, operation is also more intuitive than ever before. The improved boiler user interface with touch elements, slide control and full text display allows you to work with the device without worrying about making mistakes. All relevant functions are clearly structured and understandable - for quick navigation and settings.

Convenient monitoring with touch control and app
Smart technology doesn't have to be complicated! All heating settings can be made directly on the device using the touch controls. Menu navigation is simple and clear, and operation is now even more convenient. For simple and intuitive control of your heating system from anywhere, simply combine the sensoNET internet communication module, which is included in the package, with the new sensoCOMFORT system controller. You get easy access to all the main control functions via the free sensoAPP application. Even when you are not at home.

Flexible expansion options for increased efficiency and comfort
The ecoTEC exclusive gas boiler offers a wide range of expansion options for your heating system. Combine your boiler with one of the wide range of Vaillant hot water cylinders. The design of the new uniSTOR wall-mounted cylinders matches the new ecoTEC exclusive boiler perfectly. And although it takes up only minimal space, it can cover even the highest demands on hot water. The sensoCOMFORT system controller controls hot water preparation and up to nine mixed heating circuits. This allows for extensions such as heat pumps, solar systems or ventilation with recovery.
