Low emission design

The Vitomax family of industrial/commercial boilers is designed for clean and efficient water heating with minimum emissions. Thanks to our advanced technology, all of our boilers are characterised by low NOx emissions, making them a forward-looking investment that complies with current and future emissions targets in energy and environmental policies.

Exceptional reliability

Exceptional operational reliability and a long service life characterise all Vitomax models. This is ensured by wide water galleries and a large water content with excellent natural circulation for reliable heat transfer. In continuous operation Vitomax hot water boilers excel in terms of serviceability, thanks to the inclusion of water-cooled reversing chambers without lining.

The large cleaning doors further contribute to low maintenance costs, whilst the load bearing cover on top of the boiler is part of the standard delivery. This simplifies installation and maintenance and protects the thermal insulation against accidental damage.
