Efficient by design

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 costs.


Control your comfort

Select an easy-to-use room thermostat or, for greater control and additional energy savings, choose a Vitotronic system control. Unlike conventional boilers, which operate at a consistently high boiler water temperature, the Vitorond 100 with Vitotronic control adjusts the boiler water to outdoor temperatures, boosting efficiency while keeping your home comfortable at all times.

Thick 3½" insulation for extremely low standby losses and fuel savings.
Simple service and maintenance with full-swing left- or right-hinged combustion chamber door.
