The CIB type gas condensing boiler is a particularly cost effective solution for both residential buildings and commercial enterprises. It can already run on natural gas containing 20 percent hydrogen. This means that the Vitocrossal 100 is ideally prepared for future heating applications.

The Vitocrossal 100 (type CIB) is a compact gas condensing unit for universal application with an output of 80 to 318 kW; it is also available as a twin boiler system in a single casing with an output of up to 636 kW. Its excellent price/performance ratio makes this unit a particularly economical solution for both residential buildings and commercial enterprises.
It features the enhanced Inox-Crossal heat exchangers with a robust MatriX cylinder burner. The modulation range down to 1:5, in conjunction with a large water content, enables long burner runtimes and low energy consumption.
The Vitocrossal 100, excluding casing, measures just 680 millimetres wide, making it ideal for modernisation projects too. This is because when replacing older systems in particular, the space available for manoeuvring is often restricted.
The heat generator can be ordered as a complete unit or with individual components delivered separately. As a complete unit, it is pre-wired, pre-installed and checked at the factory. This significantly reduces on-site installation time and effort prior to commissioning. Since the boiler is equipped with castors and the pallet with a ramp, no lifting tools are required for ground-level manoeuvring.
The integral Lambda Pro Control combustion controller automatically matches the burner to the type of natural gas (E, LL) and ensures consistently high and efficient combustion quality with low emissions. The Vitocrossal 100 is suitable for open flue or room sealed operation.
The heat exchangers have been designed to combine minimal dimensions with a low weight. The stainless steel heat exchanger provides ideal conditions for utilising condensing technology. The smooth stainless steel heating surface allows the condensate created by the condensing process to simply run off downwards. The result is a permanent self-cleaning effect which ensures consistently high efficiency, increases service life and reduces maintenance requirements.
With an output range of 80 to 318 kW, the gas condensing unit is suitable for a number of applications. These include apartment buildings, large residential buildings and public and commercial premises, either as part of a modernisation project or in new build. If outputs of more than 319 kW are required, the single appliance can be quickly combined with a second to form a cascade. Alternatively, the Vitocrossal CIB is also available as a twin boiler consisting of two appliances within one casing.
The integral Vitotronic control unit enables rapid commissioning and easy operation. Just as with other Viessmann boilers, the (optional) Vitocom enables the boiler to be conveniently controlled via the internet with an app.
