The Vitocrossal 100 (CI) is a gas condensing boiler for universal use with an output of 80 to 318 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.
In its smallest available version, the Vitocrossal 100 measures just 450 millimetres, making it a good choice for replacing older systems in modernisation projects, where space is often particularly tight.
The heat generator can be ordered as a complete unit or as individual components that are delivered separately. The boiler is pre-wired and pre-installed at the factory, which significantly reduces the time and effort needed on site for installation.
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
The Vitoconnect 100 is a WiFi interface to establishes the connection allowing you to remotely operate your heating system by app, as well as supporting remote maintenance via Vitoguide.
