The Age newspaper in Melbourne ran a little story on Saturday 17th reminding us that even way down at the non-sexy end of the spectrum, geothermal energy developments are becoming popular.

The story highlighted a ground source heat pump (GSHP) system being installed on a property at Point Lonsdale, which improves air-conditioning efficiency over conventional systems by extracting heat from the ground in winter, and pumping heat underground in summer.

Business is starting to boom in the GSHP sector.
