What is an Oil Boiler?

Although the majority of UK households rely on gas condensing combi boilers for both heating and hot water, these are not always the most suitable solution. In particular, homes that are not connected to the gas grid will need to find an alternative solution. For such homes, oil boilers are the most common alternative. Oil fired central heating is estimated to be in use in approximately 2 million UK homes. 

An oil boiler works in a similar way to a gas boiler, but instead relies on oil as the fuel supply. This is stored on site in an external storage tank. Just like with gas boilers, oil boilers are now available with condensing technology, which is designed to capture and re-use the heat in the flue gasses, helping to make the boiler much more efficient and as a result more environmentally friendly.

Design & Technology

At Viessmann, we pride ourselves on designing and manufacturing futureproof and efficient heating technology for all requirements. Our comprehensive range of oil boilers successfully overcomes the most diverse challenges facing this area of heating technology by offering innovative solutions, used in a diverse range of applications from historical listed buildings and highly productive industrial complexes to the large scale residential and commercial arena.

Our oil boilers are built to last and boast a range of cutting-edge features that includes a stainless steel Inox-Crossal heat exchanger which provides ideal conditions for utilising condensing technology and ensures an extended service life. The Vitocrossal 300 is available with a factory-fitted MatriX radiant burner or prepared for fitting ELCO or Weishaupt pressure-jet gas. The convenient and easy to use Vitotronic control unit also ensures quick and straightforward commissioning, maintenance and operation.

Oil condensing technology

Oil condensing boilers equipped for the future

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. These 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. Additional heat is thus released and transferred into the heating system. This raises efficiency, lowers your heating bills and reduces environmental impact

Oil heating with solar technology uses free solar energy

You can combine the oil heating with free solar energy: All boilers are designed for the connection of a solar system for DHW heating or central heating backup. In bivalent operation, the solar system heats domestic hot water and can almost completely replace the heating during the transitional period in spring and autumn.

The combination permanently reduces heating costs and also reduces the burden on the environment. In addition, solar technology gives you a certain degree of independence from your fuel supplier. From control to spare parts to control via app: The Viessmann system technology used guarantees the interaction of all components up to a convenient control system that leaves nothing to be desired.

Future-proof heating technology saves resources

With an oil heating system from Viessmann, you will continue to be at the cutting edge of technology. Because ex works the oil boilers are already prepared for a change from exclusively fossil oil to heating oil with a proportion of bio oil and can thus also be operated with regenerative energy sources. In this way, you actively contribute to environmental protection and also keep heating costs at a low level. A long-term final switch to regenerative fuels such as the use of environmental heat with a heat pump or biomass with a solid fuel boiler can thus be realised step by step.

Convenient Vitotronic control unit

Convenient Vitotronic control unit contractors and users benefit equally from the easy-to-use Vitotronic control unit, as the structure of its menu is logical and clearly laid out and the unit is backlit, rich in contrast and easy to read. If in doubt, a help function informs users of the next steps to perform.

The graphic user interface can also display heating curves and solar yield.

Guaranteed to last

The corrosion resistant Inox-Radial heat exchanger highly efficient two-stage heat recovery and has a ten year guarantee against corrosion.
