Gas fired condensing boilers

Heating with gas – always a clean affair

By using a condensing boiler to convert natural gas into heat, you are making an active contribution towards protecting the climate and the environment, thanks to the boiler's unbeatably high efficiency of 98 % (Hs)/104 % (Hi). 

Our gas condensing boilers come with the future built in. Thanks to the Lambda Pro Control combustion control, our gas condensing boilers adjust automatically to all gas types – including biogas mixtures. This way, we will meet the many demands for heating technologies across the whole product range that protect our resources. The fact that no energy storage is necessary is also an argument in favour of a gas heating system – especially if you want to use the space for other purposes. 

You can even use free solar energy as part of your new heating system! All boilers are designed for combination with Viessmann solar technology. Viessmann system technology guarantees that everything will fit together beautifully and work in harmony, giving you convenient control that meets all your needs.
