From the space heating that keeps classrooms comfortable in cold weather to the domestic hot water used in washrooms, showers and cafeterias, your school’s boiler system must carry a significant heating load while delivering consistent, uninterrupted service. Equipment, maintenance and fuel costs, system reliability and greenhouse gas emissions must all be taken into account when addressing your heating system needs. This becomes especially challenging with shrinking budgets and growing environmental concerns. Fortunately, Viessmann has a solution that is sure to fit the bill – and your budget. The Vitocrossal 200, CM2 from Viessmann: a practical approach to innovation With its distinctive mix of proven Viessmann technology and innovative features, the new Vitocrossal 200, CM2 takes a bold step forward while retaining trusted Viessmann quality and performance. The gas-fired boiler combines unparalleled flexibility with outstanding thermal efficiency up to 97 per cent, making it an ideal choice for a new installation or an economical retrofit of your school’s heating system. Viessmann technology from top to bottom The Vitocrossal 200, CM2 utilizes advanced condensing technology to extract heat that would escape up the chimney in a conventional heating system, significantly reducing fuel consumption, heating costs and environmental impact.

to simplify installation and commissioning, its new fully modulating Viessmann premix cylinder burner features a wide modulation input range of 5:1 turndown ratio to precisely match load and provide clean, quiet and environmentally friendly operation. The generous heat transfer surface area/heat input ratio of the SA240 316Ti stainless steel Inox-Crossal heat exchanger allows for maximum heat extraction while maintaining a compact size. Its smooth, corrosion-resistant surface allows condensate to simply run off – a “self-cleaning” process that ensures continuous condensing efficiency, reduced maintenance costs and longer boiler service life. Progressive design features The Vitocrossal 200, CM2 operates with low inlet gas pressure (NG) of only four inches of water column for compatibility with a greater range of supply pressures. Extremely low water pressure drop through the heat exchanger eliminates the need for a dedicated boiler pump and low-loss header in single boiler installations, while the boiler’s large water capacity extends burner run time and reduces cycling. A versatile solution Multiple venting options (direct or chimney, up to 200 feet in length), fuel flexibility (NG/LPG/LNG) with simple electronic conversion and seamless integration into building control systems simplify retrofit projects and provide numerous possibilities for new schools. Shipped unassembled for easy trans-
portation and maximum installation flexibility, it is easy to install, even in older buildings with narrow entrances (30-inch standard doorway clearance) and small mechanical rooms. Multiple boiler systems Up to four Vitocrossal 200, CM2 boilers can operate in a cascade configuration to precisely match your school’s varying heating load (inputs of 133 to 4448 MBH), maximize boiler plant efficiency and provide security against heating plant service interruption. Harness the full potential of your Vitocrossal 200, CM2 cascade installation with the powerful Vitocontrol-S – an advanced digital boiler and system control with outdoor reset function to ensure reliable, efficient performance. The Vitocontrol-S will modulate burners, stage and rotate boilers, and regulate boiler water temperature, common supply temperature and up to two heating circuits with mixing valves.
