Proven condensing technology
Vitocrossal 300 CT3 is a commercial gas-fired condensing boiler with Inox-Crossal heat exchanger made of corrosion-resistant stainless steel. Rated input: 638 to 3361 MBH
Efficiency up to 98.3% through intensive flue gas condensation.
Easy handling in boiler rooms
Through particularly low build height and weight.
Economical and reliable heating
Through Vitotronic digital control system with communication capability.
Through perfect match of burner and boiler and low combustion chamber thermal loading.
Two return connections
Providing separate connection for heating circuits with lower return temperature, allowing for increased condensation.
Standard LON BUS
For complete integration into building management systems.
Built to last
The Vitocrossal 300 is constructed using only the highest quality materials. The Inox-Crossal vertical heat exchanger surface is made of high-grade SA 240-316 Ti stainless steel - ideal for condensing applications.
Corrosive condensate simply drains downward off the smooth surfaces, effectively self-cleaning the heat exchanger and extending the operational life of the boiler, while reducing maintenance costs.
