Automatic Heating electrifies the heating and DHW at Sydney’s EY Centre.
Located at 200 George Street, this one-of-a-kind retrofit project saw the replacement of gas boilers with two all-electric, Revere CO2 natural refrigerant heat pumps.
Direct access to the rooftop plant site was extremely limited, with no crane access to the roof of this 37-story building. To combat this, both Revere CO2 CHP-080Y2 heat pumps were dismantled and reassembled on-site in an Automatic Heating first.
To reach the rooftop, all large heat pump components were transported in a lift then vertically threaded up through a manhole. Other components of the system, including Thermex thermal storage tanks and a skid frame, were transported in a lift then carried up to the roof via an access stairwell.
Kudos to the Automatic Heating team for reconstructing two Revere CO2 CHP-080Y2 heat pumps on-site for the first time, an outstanding job.
The electrification of the EY Centre is a major milestone for Mirvac as they accelerate the decarbonisation of their portfolio. Congratulations to the team at Bridgeford Group for this project.
