New: More efficiency with the Bosch air preheating system
The new Bosch air preheating system will be available from July this year. It will preheat combustion air and reduce flue gas temperature. Boiler system efficiency will be up to two percent higher. The system is based on a hydraulic interconnection which comprises far fewer components than commercially available two-circuit systems.
The Bosch air preheating system is offered as a standardised version for Bosch single or double flame tube steam boilers with duoblock burners. The system is economically viable from boiler capacities of approximately five tonnes of steam per hour. The option of installing the fan on the boiler top enables the realisation of an extremely compact system with a small supporting surface. The return on investment (ROI) is usually between 1.5 and 2 years.
