The Vitocrossal 300 type CR3B gas condensing boiler The Vitocrossal 300, type CR3B, is the top model amongst floorstanding gas condensing boilers, available from 787 to 1400 kW. As a single boiler system, it is the most powerful condensing boiler in the comprehensive range offered by Viessmann. This makes it equally suitable for residential complexes, local heating networks, larger public and commercial buildings and industrial plants. Advanced condensing technology The design of the Inox-Crossal heat exchanger enables the Vitocrossal 300 to produce a higher output of up to 1400 kW, whilst retaining its modest dimensions and low weight. In addition, the split design of the heat exchanger module and combustion chamber module makes manoeuvring easier. The highly effective heat transfer and the high condensation rate enable standard seasonal efficiencies [to DIN] of up to 98 % (Hs) [gross cv] to be achieved. These high levels of standard seasonal efficiency are the result of the countercurrent principle related to hot gas and boiler water, along with intensive turbulation of the hot gases as they pass through the heat exchanger. The second return connector of the Vitocrossal 300 enables a hydraulic connection that is highly beneficial to the utilisation of condensing technology. Vitocrossal 300 gas condensing boilers are available with factory-fitted ELCO or Weishaupt pressure-jet gas burners.
