Heating with oil - technology with up to 98 percent efficiency

By using a Viessmann condensing boiler to convert fuel oil into heat, you are making an active
contribution towards using resources efficiently and saving energy, thanks to the boiler's unbeatably high efficiency of 98 percent*.

Our oil condensing boilers come with the future built in. They are designed to accommodate a
changeover from fossil oil to fuel oil mixed with a certain percentage of bio-oil, which means that they can be run partially on renewables.

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, putting you in control and meeting your every demand.

Oil heating - efficient resource with condensing technology
 

Condensing boilers extract almost all of the heat contained in the flue gases and convert it into additional heating energy. To do this, Viessmann condensing boilers are equipped with stainless steel Inox-Radial heat exchangers, which cool the flue gases before they are routed into the chimney, to the extent that the water vapour contained in these gases is deliberately condensed, and the additional heat released is transferred into the heating system. Furthermore, this technology reduces heating bills and effectively minimises emissions.
