Viessmann Climate Solutions UK has launched a new range of high-efficiency, low-emission, commercial gas condensing boilers – the Vitocrossal 200 CI3.
With eight output sizes from 80-640 kW and integrated-control cascade operation up to 5120 kW (eight units), the Vitocrossal 200 CI3 is flexible and compact, which is said to be ideal for modernisation projects or buildings where space is limited. Each unit is just 750mm wide, occupying 1.07m2of floor space – a reduction of 55% compared to previous Vitocrossal 200 models.
Thanks to its single or dual modulating MatriX cylinder burner with stainless steel heat exchanger, as well as an automatic combustion controller that contributes to ease of commissioning and increased operational safety, the Vitocrossal 200 CI3 provides consistently efficient and high quality combustion throughout its long service life.
The boiler has a standard seasonal efficiency of up to 94.8% and NOx emission levels below 27 mg per kWh. A self-calibrating O₂ sensor automatically adjusts the MatriX burner to match different types of gas so natural gas and LPG can both be used. Additionally, the product is prepared for future changes in gas fuels.
Performance is further enhanced by the boiler’s large modulation range of 1:10, which offers greater efficiency at partial load. It also has two return connections as standard, so that there can be low- and high-temperature circuits if desired, with a lower temperature return for better condensation. The maximum flow temperature of the high-temperature circuit is 95 degrees Centigrade.
The Vitocrossal 200 CI3 adheres to Viessmann’s philosophy of using a high water content heat exchanger. This avoids the requirement for a minimum water flow, which reduces the need for expensive and energy-consuming boiler shunt pumps.
Ease of installation and management
Supplied with integrated wheels and a practical transport pallet for enhanced manoeuvrability as well as a simplified electrical-connections terminal easily accessible at the back, the factory-tested, pre-assembled units are convenient to install and service. Complete accessory packs are available for room-sealed installations and twin solutions and all components can be easily reached from both the front and the rear.
Viessmann’s ViGuide app for installers makes the intuitive commissioning process easy, with the option of using a smartphone or tablet instead of the integrated digital control panel. It also gives contractors direct access to optimise and monitor the system remotely on an ongoing basis.
The Vitocrossal 200 CI3 is the first of Viessmann’s commercial boiler offerings to be integrated into its One Base climate- and energy-management platform with built-in WiFi. One Base allows for simple, reliable and convenient operation of the entire energy system, as well as automatic optimisation of energy flows for maximum cost-effectiveness. This is via the Viessmann ViCare app for end-users and their maintenance contractors, and via the ViGuide app for installers and M&E contractors. One Base can easily be connected to other digital building management systems (BMS) to provide a single, user-friendly control and monitoring solution, without the need for an internet connection (although wired ethernet can be used if preferred).
