Modular frames and accessories for cascade management enable high outputs to be achieved in a confined space.

An outside weather sensor is standard with every boiler. Siemens controls can provide multi-boiler cascade management (standard), multi-zone management and control of DHW. Also supplied as standard is control for modulating pumps. These boilers can be fully integrated into a BMS.
