Geoexchange
heating and cooling was first introduced to Australia in 1992 though
the Adelaide-based WaterFurnace Australia. To provide a more personal
and unique way of reviewing this history, we asked one of the pioneers
of the technology, Richard Metcalf, to provide his recollection of the
past twenty years.
We first formed WaterFurnace Australia
back in 1992. I was the Marketing Manager for the Electricity Trust of
South Australia (ETSA) at the time and I was approached by Alistair
Hutchison, a local mechanical engineer, about the WaterFurnace product.
In fact, Alistair first approached me in 1989 and in conjunction with ETSA we installed three geoexchange installations. It was in 1992 that I left ETSA and we started WaterFurnace Australia. This was a very different concept at the time but I immediately caught
what I refer to as 'geothermalitis' and developed a passion for the
technology that stays with me to this day.
WaterFurnace Australia was originally half owned by WaterFurnace but quickly became a fully Australian owned company.
Our first installation was a
residential home in suburban Adelaide. This was quickly followed by
homes across Adelaide and surrounds and quickly into the ACT. In a
similar way that the National Rural Electric Cooperative Association was
an early supporter and promoter of the technology in North America,
much of our early support came from the old regional electricity
suppliers such as ETSA in South Australia and Great Southern Energy in
southern NSW.
Commercial installations followed soon
after, with the iconic system being the new Geoscience Australia
(formerly Australian Geological Survey Organisation - AGSO) building in
Canberra that was commissioned in 1996. Other major installations at the
time included Lithgow Hospital, Macquarie University, Garden East
Apartments in Adelaide and the Hobart Aquatic Centre.
Origin Energy (Boral at the time)
started to express interest in the technology at this time and purchased
the company and the rights to the WaterFurnace distribution in 1998. I
stayed on as a consultant to them for several years.
Despite the promise of over 200 retail outlets and a commercial sales
division, it was one of those unfortunate stories of a technology not
quite fitting into an established corporate. The electrical efficiency
product never seemed to quite fit within what was at the time a major
gas company and some of the early drivers within Origin were promoted
internally - away from the WaterFurnace business. The end result was a
business division that seemed to float around and never took off in the
way that was expected. This was never a reflection of the technology
itself or a repeat of the electric car conspiracy, rather just a
corporate mismatch.
WaterFurnace ended up revoking the license to Origin and I was
approached to manage their local distribution again. I fulfilled this
role until 2005 when we were first approached by GeoExchange Australia
and they became the driving force behind the technology.
Although officially semi-retired, my role now is to manage the service
and spare parts of the business and to provide advice to both
GeoExchange Australia and GAIN, their dealer network, on an as required
basis. I also keep my hands dirty with one or two local installations
each year for family and friends.
I enjoy seeing the way that the technology is now becoming more main
stream as we always felt that we were before our time with respect to
full acceptance and uptake of the technology. Now is definitely the
right time for the technology.

past, present or future of geoexchange systems.
