Why Geothermal Heating & Cooling
Geothermal heating and cooling systems can be installed virtually in any area of Australia to save energy and money. Some of the benefits of geothermal systems are:
1- According to the United States Environmental protection agency (EPA), “Geothermal heating and cooling systems are the most energy efficient, environmentally clean, and cost effective space conditioning systems available”. (Source: Space Conditioning: The Next Frontier, EPA 430-R-93-004)
2- Residential Geothermal heating and cooling systems are usually more expensive initially to install than the conventional Gas heater/boiler/refrigerated air conditioning. However, the higher efficiency of the geothermal systems, means the investment can be recouped in two to 8 years. After that, the energy and maintenance costs are much less than the conventional systems. Note that based on a report by Energy Consult July 2015 (energy rating.gov.au), 40% of average Australian house hold energy bill is for heating and cooling building spaces.
3- Commercial geothermal heating and cooling systems are extremely competitive on upfront costs when compared with cooling towers and boilers and they have lower energy and maintenance costs.
4- The geothermal heating and cooling system also offer aesthetic advantages as they have no massive outdoor units, offer quiet operation and improved comfort.
5- Free or reduced –cost hot water, unlike any other heating and cooling system, a geothermal heat pump can provide free hot water. A device called desuperheater transfers excess heat from the heat pump compressor to the hot water tank. In summer the hot water generated by the geothermal system is absolutely free and in winter, water heating costs are 75% less. Note that based on a report by Energy Consult July 2015 (energy rating.gov.au), 23% of average household energy bill is for hot water heating and this option of geothermal system can save considerable amount of energy consumption and the associated costs.
