High efficiency with low emissions
The stainless-steel heat exchanger in Viessmann’s Vitocrossal 300 condensing boiler achieves a service life equal to or better than conventional boilers.
NOx emissions from Viessmann’s Vitocrossal 300 condensing boiler are lower than the stringent German Blue Angel requirements. The stainless-steel heat exchanger is said to have a service life equal to or better than conventional boilers and deliver an efficiency up to 98% gross. This fully modulating boiler delivers up to 185 kW using the MatriX radiant burner. Two return tappings are provided, and the boiler will operate to any flow temperature. Both low- and high-temperature circuits can be supplied at the same time. These boilers can be matched with a choice of Vitrotronic control packages providing time and weather-compensation control. They ensure virtually continuous condensing operation by keeping the boiler temperature as low as possible.
