MatriX cylinder burner

Advanced condensing technology makes the Vitocrossal 100 an economical boiler suitable for many different applications

The Vitocrossal 100 (CI1) is a gas condensing boiler for universal use with an output of 80 to 320 kW. With the excellent price/performance ratio, the energy centre is an especially economical solution for residential buildings and commercial enterprises alike.

It features the proven Inox-Crossal heat exchanger with robust MatriX cylinder burner. The modulation range of up to 1:5 ensures long burner runtimes and economical energy consumption.

Complete and compact

In its smallest available version, the Vitocrossal 100 measures just 450 millimetres, making it a good choice for modernisation projects. Space is often particularly tight when replacing old systems.

The heat generator can be ordered as a complete unit or as individual components that are delivered separately. It is pre-wired and pre-installed at the factory. This significantly reduces the time and effort needed on site for installation.

Advanced condensing technology

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 heat exchanger allows the condensate created by the condensing process to simply run off downwards. Combined with the smooth stainless steel surface, this creates a permanent self-cleaning effect, which ensures permanently high efficiency, increases the service life and reduces the maintenance effort.

The highly effective heat transfer and high condensation rate enable standard seasonal efficiency [to DIN] of up to 98 % (Hs) [gross cv] / 109 % (Hi) [net cv]. These high levels of standard seasonal efficiency are the result of the countercurrent principle related to hot gas and boiler water, along with the intensive turbulation of the hot gases as they pass through the heat exchanger.

Lambda Pro Control reduces costs

The integral Lambda Pro Control combustion controller automatically adjusts the burner to the type of natural gas (E, L, LL), ensuring consistently high and efficient combustion quality with low emissions. The Vitocrossal 100 is suitable for open flue or room sealed operation.

Proven Vitotronic control unit

The integral Vitotronic control unit enables rapid commissioning and easy operation. With the optional Vitoconnect 100 WLAN module, the boiler can be conveniently controlled online via app. The Vitotronic 300-K (MW1B) cascade control unit covers up to eight boilers.
