Vitoradial 300-T - efficient with condensing technology


Benefit from these advantages

  • Optionally available with gas or oil burner
  • Conversion of the fuel used (heating oil) into heat up to 97 percent
  • Environmentally friendly operation due to long burner running times; large water content requires fewer switching intervals
  • Compact design with low appliance height (important for modernization)
  • Easy to operate Vitotronic control unit with plain text and graphic display


High efficiency with two-stage heat recovery

The Vitoradial 300-T is an innovative combination of the Vitoplex 300 low temperature boiler with a directly mounted Inox-Radial heat exchanger for condensing.

The proven convection heating surfaces and corrosion-resistant heat exchanger enable highly efficient two-stage heat recovery.

The Vitoradial 300-T is suitable for operation with all commercially available EL fuel oils or natural gases. Its output ranges from 101 to 545 kW.

Thanks to its compact design and low installation height, the Vitoradial 300-T is ideally suited for modernization, e.g. of oil heating systems in apartment buildings.

The user benefits from easy cleaning of the combustion chamber with low maintenance costs.

Condensing boiler with Inox-Radial heat exchanger

The Inox-Radial heat exchanger offers condensing technology even for medium boiler systems such as the Vitoradial 300-T. It increases the efficiency by eight percent to 97 percent.


With this principle, combustion and condensation take place spatially separated from each other, with the combustion gases condensing without deposits.

A perfect match - system technology

"The whole is greater than the sum of its parts." In line with this principle, Viessmann not only offers individual heating components that meet the high Viessmann standards in terms of quality, reliability and effectiveness. Rather, all products are integrated into a coordinated complete system in which all components fit together exactly. Because only the perfect interaction of system-integrated components exploits the full performance potential of innovative, cutting-edge technology.

Viessmann system technology includes everything that makes a reliable and economical heating system. The Vitotronic control unit with wireless remote control, powerful Vitocell DHW cylinders for optimum DHW convenience, and high-quality solar thermal systems for cost-saving central heating backup.
