#  Case Studies 

Our portfolio showcases how SóGeo’s sustainable heating and cooling solutions have transformed homes and businesses across Melbourne and greater Victoria. From heritage home retrofits to modern new builds, explore the real-world results in the case studies below

 

 

 

   [ ![Coimadai]() ](https://sogeo.com.au/case-studies/case-study-sogeo-revolutionised-home-comfort-in-coimadai-victoria)### [Coimadai, Victoria: Geothermal Heating, Cooling and Ventilation for a New Build, SCOP 8.1](https://sogeo.com.au/case-studies/case-study-sogeo-revolutionised-home-comfort-in-coimadai-victoria)

Terry and Lynne Lefoe’s new build in Coimadai runs underfloor heating, cooling and heat recovery ventilation from a Stiebel Eltron geothermal system on four 99 m boreholes, drilled into mudstone in a single week. Measured SCOP: 8.1, the highest of any SóGeo project we have published.

A heritage-listed home near the Kooyong tennis club, extended and fitted with geothermal heating and cooling on five 120 m boreholes drilled by GT Drilling on a tight site. A Stiebel Eltron WPE-I 33 carries the heating and a water-cooled Mitsubishi Electric VRF the cooling, with no outdoor plant to disturb the heritage streetscape. Currently running at a COP of 6.5.

Grant’s Main Ridge home already had hydronic underfloor heating. A 15 kW Stiebel Eltron heat pump drawing on the property’s spring-fed lake replaced the old plant with no drilling, a one-week install and a measured SCOP of 5.1, despite a demanding 50 to 55°C flow temperature.

David and Jenny’s remote property ran on an oil boiler and a propane pool heater. A 70 kW Stiebel Eltron geothermal system on eleven 100 m boreholes now heats the home and the indoor pool with no fossil fuels at all, at a measured SCOP of 7.4.

A luxury new build on the Port Campbell coast with no three phase supply and salt air on every side. Horizontal ground loops, a Stiebel Eltron geothermal plant room beneath the indoor pool, a measured SCOP of 5.2 and a 70% reduction in the home’s power consumption.
