Mooroolbark Aged Care Facility

This changeover, performed by GMR Mechanical is comprised of a heating as well as domestic hot water system. The heating plant consists of 3 x 120kW Baxi PowerHT boilers in cascade controlled by a RVA47 Sequence Controller while the domestic hot water plant consists of 2 x 120kW Baxi PowerHT boilers that feed two calorifiers. The flue components of each boiler are combined into one common polypropylene flue with a stainless steel riser. Each boiler has a flue shutter kit which prevents flue gases from spilling into non-operating boilers or the plant room.

Melbourne Old Treasury Building

Melbourne’s Old Treasury Building, built in the mid-19th century, had a boiler upgrade carried out by A.G. Coombs. The new system is comprised of 2 x 150kW Baxi PowerHT boilers controlled by a RVA47 Sequence Controller. The flue manifold system is polypropylene plastic with a stainless steel riser and is coupled into one common flue for both boilers. Each boiler has a shutter kit that prevents flue gasses spilling out where they shouldn’t and the condensate is treated and sent to the sewer via a condensate treatment tank.
