Vitocrossal 100

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 whilst the smooth stainless steel heat exchanger allows the condensate created by the condensing process to simply run off downwards. The result is a permanent self-cleaning effect, which ensures permanently high efficiency, increases the service life and reduces 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 turbulence of the hot gases as they pass through the heat exchanger.

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.

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.

Unlike other floor-standing boilers, the Vitocrossal 100 delivers the best of both worlds. As standard it delivers the benefits of a high water content boiler with no minimum flow rate requirement, no boiler pump requirement and subsequent savings on electrical running costs. Yet it is pre-wired and pre-assembled, like wall-hung boilers
