Discontinuation notice
The Vitocrossal 300 CT3 boiler series has been discontinued. If you are looking to purchase a new commercial gas-fired boiler, please consider the Vitocrossal 200 or Vitocrossal 300 CA3B series.
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.
