The Vitocrossal 100 has a very small footprint, due to its new stainless steel heat exchanger; the floor-standing gas-fired condensing boiler features Lambda Pro technology for performance and efficiency.

The Vitocrossal 100 sits inside a new-shape casing which measures just 680mm wide and 1459mmhigh, with length varying (according to output) from 660 to 1010mm.

There’s a choice of seven models, from 80 to 320kW, plus the option of a twin cascade within a single casing for up to 640kW.
