We ensure that all the right components are included with the system.
Strength in numbers
As many as eight Vitodens 200-W gas-fired condensing boilers can be combined in a single prefabricated cascade system, with inputs up to 4240 MBH. A cascade system fires boilers as required to meet fluctuating heating demands; it maintains maximum efficiency at all times by precisely matching the load.
Get industry-leading condensing technology for your commercial projects with a high-performance Vitodens 200-W multiple boiler system.
Controlling your cascade
Get the best performance from your multiple-boiler installations with the Vitotronic 300-K, MW2C Cascade Control. This advanced digital boiler and system control with outdoor reset function ensures reliable and efficient performance of a cascade system with up to eight boilers (with Vitotronic 200, HO1B controls).
The Vitotronic 300-K control will modulate, stage and rotate boilers, regulate boiler water and common supply temperature, and with optional extension module, can control up to two heating circuits with mixing valves. Plus, set-up is fast and easy with its plug-and-play function for automatic recognition and adaptation of sensors and system accessories.
