    Oil condensing boiler

    With condensing technology, not only is the heat from the combustion of fuel oil or gas utilised, but also the heat that, with non-condensing heating technology, would otherwise escape unused up the chimney.

Heating with oil

By using a Viessmann condensing boiler to convert fuel oil into heat, you make an active contribution towards utilising resources efficiently and saving energy, thanks to the boiler's unbeatably high efficiency of 98 percent (relative to the gross calorific value (Hs)).

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
