The oil condensing heating system – efficient, futureproof technology
When using a condensing boiler to convert fuel oil into heat, you can make an active contribution towards protecting the climate and the environment, thanks to the boiler‘s unbeatably high efficiency of 98 % (Hs)/104 % (Hi)
Our oil condensing boilers come with the future built in. They are already set up to change from using fossil oil to fuel oil with a proportion of bio-oil. This way, we will meet the many demands for heating technologies across the whole product range that protect our resources.
You can even use free solar energy with 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.
