  • Maximum heat extraction and efficiency thanks to the triple-pass heat exchanger.
  • Long service life and maximum reliability with extremely durable cast iron heat exchanger.
  • Clean and efficient combustion thanks to the stainless steel combustion chamber insert.
  • Quiet combustion with Beckett or Riello burner.
  • For greater efficiency and comfort, modulate the boiler water temperature with a Vitotronic control.
  • Eliminate the need for a chimney and combustion air supply opening with the direct vent option (VR1 models 22 to 33 and 91 to 140).
  • Low maintenance cost with service-friendly burner and easy-to-clean flue gas passageways.

The Vitorond 100, with its triple-pass heat exchanger, is designed to achieve a high level of efficiency while providing exceptional comfort. Unlike single-pass boilers, the Vitorond 100 guides flue gasses through the heat exchanger three times, allowing the greatest amount of heat extraction to be achieved. This design significantly increases the efficiency of the boiler and results in excellent fuel utilization, reducing emissions and your heating cost.
