Sydney’s newest luxury hotel is fashioned from two prominent, state-listed heritage buildings in Sydney’s “Sandstone Precinct”; the Lands and Education Department Buildings, constructed between c1876-1892, and c1912-1930, respectively. Located in the heart of Sydney’s CBD, the Sandstone Precinct features 192 rooms, a number of bars, a commercial kitchen and a 25-metre pool.


Stantec Engineers approached Rheem to assist with the sizing and design of a centralised gas hot water system, to service the rooms and the hotel’s commercial kitchen. The project required a centralised system that could deliver a hot water load of 22,632 litres over a one-hour peak period while working within heritage building specifications.


With multiple hot water circuits connecting the two historic buildings and a large hot water load requirement, the Sandstone Precinct brief was a challenge. However, Rheem worked to find a solution for this unique project. Working with JRK Group, Rheem provided three 800kW Rheem Crossflow heat exchange delivery skids, combined with Raypaks and Rheem stainless steel storage tanks. The tanks were chosen for their large capacity and durability, Raypaks for their fast-heating capabilities, while the Rheem Crossflow delivery skids assured instantaneous thermal transfer and solved the high-pressure design requirement.
