The high quality stainless steel Inox-Radial heat exchanger efficiently converts the supplied energy into heat. The stainless steel cylinder burner therefore consumes relatively little natural gas, with lower CO2 emissions and less impact on the environment as a result.
With our optional easy-to-install tado° thermostat and smartphone app, you can optimise your heating environment and save energy costs from the palm of your hand - no matter where you happen to be.
The Vitodens 050-W comes with a 3 year comprehensive warranty as standard, with an extended warranty option of up to 7 years available if fitted by a Viessmann Trained Installer.
