The Royal Hobart Hospital (RHH) provides  general and specialty medical and surgical services.  It serves a population of 240,000 people and has 490 beds including 86 day beds.

Between 1995 and 1999, a series of significant projects were undertaken to upgrade and redevelop nearly 80% of the current campus site.  One aspect of this was a major Engineering Services Upgrade.

A Performance Contract was entered into between the Honeywell organisation and the Government of Tasmania.  Systems and services upgraded as part of the project included the installation of Accent hot water heat pumps to replace redundant electrode boilers and site-wide heating water reticulation. The upgrades were completed in August 1999 with the energy guarantee period commencing in late July.  The guarantee is for a reduction in energy costs of some $300,000 per annum.

Hot Water Supply

The heat pumps were installed in groups of up to four units across four buildings of the campus.  The units were linked to hot water storage of up to 10,000 litre tanks for provision of a tank temperature up to 65°C.  Detailed monitoring of hot water usage was undertaken, with a maximum hourly use of some 3,400 litres being shown for GEHA building and with continuously strong hot water demand of an average 2,000 litres/hour over the 10 hour period from 9AM to 7PM.

Accent equipment supply

Equipment supply included 13 Accent Hot Water Heat Pumps each of 42KW nominal output, giving a total 546KW total capacity.

The success of the project was reflected in the continuing introduction of further units over three stages and the subsequent additional upgrade to the Calvery Private Hospital.
