These are the questions we frequently get asked about our geothermal heating, cooling and hot water systems. If your question isn’t listed here, contact us and we’ll be happy to answer it.

In its raw state, copper comes from the ground. We install a sacrificial anode for each system. These anodes have an electric AC/DC current that runs through the copper, protecting the lines from any adverse ground conditions.

Due to the fading out HCFC Refrigerants we have designed our unit using R410a which is a high pressure, highly efficient azeotropic blend of HFC 32 and HFC 125.

Unlike open loop systems and water loop systems that need frequent maintenance in topping up water and glycol levels, DX Geothermal systems require little to no maintenance except for cleaning the return air filters, just like any other air/con system.

DX’ Geothermal requires only one heat exchange transfer, compared to the two step transfer in water-based systems demanding about twice as much energy consumption – ‘DX’ 30% more efficient than any other geothermal system.

Water loop requires a water pump – ‘DX’ does not. ‘DX’ runs on the same scientific principle as a Refrigerator, the most reliable appliance in the home.

Water loop involves invasive excavating and expensive deep well drilling – ‘DX’ does not, only small bore holes or trenches.

Water based systems use plastic tubing in which a water/glycol, anti-freeze or alcohol solution is circulated this presents a serious problem in the event of a leak, this is not an uncommon occurrence for water based systems. – ‘DX’ distributes an environmentally friendly refrigerant through copper tubing. Copper tubing is a superior heat conductor and is far less likely to leak – proven more reliable and much more efficient than plastic.

‘DX’ applications include Residential and Commercial. In addition ‘DX’ specializes in a broad base of applications, Restaurants, Hotels, Sports Clubs, Spas.

AusGeothermal manufactures our units with only the highest quality parts available. Our system is expected to last twice as long as a conventional system.

If there are more than 30 metres x 10 metres of ground surface area clear to work with, ground loops could be trenched, resulting in cheaper installation costs. Vertical drilling is as effective and more suited to smaller ground space applications.

On average from beginning of installation to completion would take approximately 1-2 weeks.

Yes. In most cases existing ducting and some air handlers can be used resulting in cheaper costs and faster installation.

Yes. This is a very effective way to reduce your home energy consumption. All existing equipment can be re-used providing it is currently in a working condition.

Location of the compressor heat pump unit does not have to be outdoors due to our system not requiring any coil or fan mounted in the system. Therefore, this can be installed in utility rooms, garages or outdoor areas. Outdoor units and hot water vessels can be manufactured on a neat and compact steel frame/base which is pre-piped and pre-wired for easy installation.
