Condensing boilers have self-cleaning heat exchanger

Viessmann’s Vitrocrossal 200 range of condensing gas-fired boilers is designed to offer outstanding performance to a tight capital budget. These boilers are available with outputs of up to 311 kW. They can be installed in pairs using preformed flue and header kits. These pairs can then be combined so that four boilers can give a total installed load of up to 1244 kW. The pre-mix Matrix burner can modulate down to 30% of full load and have noise levels comparable with those of a domestic boiler. The stainless-steel heat exchanger is self cleaning to ensure long life and consistently high operating efficiency of 97% gross. Vitrocrossal 200 boilers can operate with open flues or fanned flues. They also include the Vitrotronic control systems, giving a wide choice of stand-alone control options or a connection into a building-management system.
