St John of God Hauora Trust
Hot Water Heat Pump Turn Key Project
$30,000 Domestic Hot Water Cost Reduction & a 3 Year Payback on a DETA Turnkey Project
Problem
St John of God (SJOG) had a distributed hot water system that was starting to fail. They were looking for a long term solution, while also looking to reduce their operating costs.
Solution
DETA prepared a business case to replace four existing hot water cylinders with a centralised ring main with a heat pump. The system proposed was more technically complex than the existing system, but offered redundancy in heating (heat pumps and re-purposing gas boilers) and could also provide heat for an existing underfloor heating system. DETA designed, consented, project managed and commissioned the system.
Outcome
The project was installed within an operational hospital with no reduction in hot water service. It has reduced hot water costs by 70%, and reduced underfloor heating costs by 60%. The system was delivered under budget, started operating in January 2016 and has run faultlessly.
