    Gas condensing boiler Vitocrossal 300 Type CR3B

    The Vitocrossal 300 CR3B is a gas condensing boiler delivering an output of 787 to 1400 kW. As a single boiler system, it is Viessmann's most powerful heating centre.This makes it just as suitable for residential complexes as for local heating networks, larger public and commercial buildings and industrial plants.

    The Vitocrossal 300 is supplied with a pressure-jet gas burner from either ELCO or Weishaupt.

    The design of the heat exchanger in the Vitocrossal 300 enables high output levels, yet retaining modest dimensions and a low weight.

    To facilitate handling, the condensing boiler can be delivered in two sections.

    Comfortable and powerful Vitotronic control

    The Vitotronic control system with a large colour touch display allows fast commissioning by means of an assistance function as well as simple operation. Via the integrated LAN interface, the boiler can be directly connected to the Internet for remote monitoring. The Vitosoft 300 service tool communicates directly via WLAN. Energy consumption can be easily viewed via the control energy cockpit.
