The combined 240kW BFC Cyclones from A.O. Smith are fully room-sealed condensing high-efficiency water heaters (97% gross). Flexible flue options allow them to be placed almost anywhere, providing numerous options for designers working on new building projects like Bromsgrove Leisure Centre. This water heater is fitted with an automatic gas/air premix burning system including burner modulation for improved efficiency. The water heaters feed to an Adveco Stainless Steel Twin-Coil (SST) calorifiers, each of which is supplied with a pair of independent internal heat exchange coils to serve the centre’s DHW system. Each high-output coil can be used with a separate heat source, enabling effective integration of renewable technologies or multiple heat sources, or as in this case are combined to increase the heat transfer capacity from a single high-output source.
