Floor standing gas boilers


The  Vitocrossal  range, from 87 to 1400 kW, offers a perfect solution for every application - from heating apartment buildings and public or commercial premises, through to generating heat in local heating networks.

The ideal boiler for every application

Vitocrossal gas condensing boilers boast a range of features including advanced condensing technology, convenient control units, exceptional efficiency and low emissions.

Our Vitocrossal boilers are designed with both current and future needs in mind and as a result not only comply with current environmental legislation, but will continue to do so long into the future, even as emissions limits become stricter.


Advanced condensing technology

The stainless steel Inox-Crossal 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, thus ensuring that the condensing technology is utilised at a permanently high level, resulting in a longer service life whilst also reducing the maintenance effort.
