What is Geothermal?
Geothermal applications have been in use for many decades in north America and Europe as a highly efficient and reliable source of heating and cooling. Commonly referred to as Ground Source Heat Pumps, a geothermal heating and cooling system utilises the constant ground temperature to either reject heat, in summer, and collect heat in winter.
Ground Source Heat Pumps have a long life span and with fewer moving parts than a conventional air conditioning system they also require far less maintenance.
GeoAir is the new generation of geothermal cooling and heating Where older generation geothermal circulated water through ground loops, GeoAir circulates R410A refrigerant gas. The benefits of this include:
- Increased heat transfer rates delivers genuine savings in the installation costs as less wells are required. Ground works in geothermal are always the most expensive part of the installation. GeoAir requires less wells, meaning lower costs.
- Reduced loop field footprint provides greater application. Less wells also means the technology can be used across a broad range of sites.
- GeoAir does not circulate water through ground loops, meaning there is no need for water circulation pumps. This removes one source of power consumption and therefore increases efficiencies.
Selecting a ground source heat pump for your project is a sound financial investment as well as a genuine renewable solution.
Frequently Asked Questions
Who is GeoAir
GeoAir is an Australian designed and manufactured business that is owned by Alinta Energy, one of Australia’s leading energy companies. We operate in all major centres on the East Coast of Australia.
Where is GeoAir Manufactured
Here in Australia in partnership with one of Australia’s leading air conditioning manufacturers. We are proud to be providing employment and capabilities within the local renewables and manufacturing sectors.
How efficient is a GeoAir?
GeoAir is a ground source heat pump which are recognised as one of the most efficient heating and cooling systems available today. With efficiencies typically greater than 50% against a conventional system, a GeoAir system will provide significant benefit for life of the installation.
How much does a GeoAir System Cost?
Depending upon your project, a GeoAir system will be typically between 30% to 40% in additional upfront costs against a conventional air conditioning system.
Can a GeoAir System Cool and Heat?
GeoAir is a reverse cycle system that can both cool and heat and operates in the same way as a conventional air conditioning system.
How long will a GeoAir system last?
GeoAir loops will outlast the ownership of the home. All loops are copper and are manufactured under strict quality control. All above ground systems are serviceable and can be refurbished after years of operation.
What about the noise?
A GeoAir system operates at 51db significantly less than a conventional air conditioning system offering flexibility in design and location for the outdoor units.
Is GeoAir Safe?
The GeoAir heat pump has no external fan or moving parts making the external units safe for children and pets.
Can GeoAir Heat Water?
GeoAir can heat water for any application; potable hot water, swimming pool or hydronic / in slab heating. Through using the waste heat from the system, GeoAir can be configured to produce hot water passively when operating in cooling.
What type of building can a GeoAir system be used in?
We have systems operating in single homes through to large commercial buildings, shopping centres, aged care facilities and office buildings. We have installed systems ranging in size from 13kW through to over 600kW. Provided the building has the available space for the geothermal loops, a GeoAir system can be considered.
Installing GeoAir at Fairwater was a meaningful way of reducing energy costs for our customers and delivering an environmental benefit for Frasers Property.Paolo Bevilacqua
Representing a significant cost for all buildings, the ability to reduce HVAC energy consumption is always a high priority. GeoAir is always a consideration for us on all projects we review as a genuine means of achieving energy reductions.Rob Saunders
QPS Geothermal were always responsive and ensured works were managed and completed to a high standard. The geothermal system installed to our project is a centrepiece of this sustainable building.Ben Reid
