The Queen Elizabeth Hospital (TQEH) is a 303-bed, acute care teaching hospital. Opened in 1954 as a maternity hospital, TQEH was the first hospital in Australia to successfully perform kidney transplantation and is now the second-most utilised hospital in South Australia. Caring for Adelaide’s western suburbs, a population of more than 250,000 people, the hospital provides inpatient and outpatient services, inclusive of surgical, oncology, renal dialysis and mental health, as well as emergency.

The brief

Rheem was brought on board in partnership with System Solutions Engineering to assist with the hot water upgrade of the northeast wing of TQEH. The system requested was solar preheat with inline gas boost with redundancy, supplying hot water to 25 ensuite rooms, over 20 consulting rooms, 12 kitchenettes and more than 60 hand basins. While upgrading a hot water system in a working hospital presented its own challenge, a tight plant room with minimum downtime on hot water added additional pressure.

The Solution

The solution for TQEH was split into two points of focus — the Inline Gas boost and the Solar Preheat. The carefully-staged installation, in partnership with Hindmarsh Plumbing, used a Rheem Tankpak Series 3 model TPI04NFD, with dual primary and dual secondary integrated circulators, pre-assembled and factory tested in Australia for the Inline Gas Boost. The Solar preheat used a Rheem Crossflow as a solar separator, a three-way valve for secondary solar circulation, two RT2000N9ALU storage tanks and 30 NPT200 solar collectors.
