Green Savings: How the New Energy-Efficient Cooling and Heating Systems Can Help You Save Money
One of the Biggest Costs
Maintaining a comfortable indoor temperature is one of the biggest ongoing expenses in most Australian households today.
Heating and cooling consume large amounts of electricity and fossil fuels, increasing utility costs and environmental impact.
Modern, energy-efficient systems help lower these costs, offering homeowners smart options for upgrading their home’s climate control.
Energy-Efficient Heating Systems
Heating accounts for nearly 50% of home energy use, creating opportunities to save by installing more energy-efficient heating systems.
A Victorian Government report found efficient gas heaters can save up to $280 yearly and cut emissions by two tonnes.
Gas heating avoids electricity from coal-fired plants, making it a greener choice with rising electricity costs.
New ducted gas systems now achieve six-star efficiency, offering consistent comfort even in cold weather and reduced energy bills.
Non-condensing five-star models don’t need draining, making them easier and cheaper to maintain.
Wall furnaces are compact, efficient (up to 4.8 stars), and heat two rooms when paired with a rear register kit.
Gas log heaters offer a fireplace aesthetic while efficiently warming living areas with up to 5.1-star ratings.
Energy-Efficient Air Conditioning Systems
Evaporative cooling uses hot air passed over moist pads, cooling via evaporation with minimal electricity use.
Only pumps and fans need power, unlike refrigeration-based systems which rely on energy-hungry compressors.
Evaporative systems can be up to 50% cheaper to install and cost just one-eighth as much to operate.
Refrigerated systems are improving, with reverse cycle technology offering better energy control and compressor efficiency.
Modern systems range from three to six stars; choosing higher-rated units improves performance and reduces electricity bills.
Five- and Six-Star Heating and Cooling
Star ratings measure how much input energy is converted into usable heating or cooling output.
Each star typically represents a 10–15% boost in efficiency, moving closer to 100% energy conversion.
Gas systems now achieve five-star or six-star ratings, offering superior performance and reduced environmental impact.
Easy Programming, Installation, and Maintenance Reduce Operating Costs
Computerised controls direct specific amounts of heated or cooled air into designated rooms, improving efficiency.
Timers and temperature settings reduce unnecessary usage, keeping energy bills low without sacrificing comfort.
Choosing smaller non-condensing heaters reduces installation costs compared to larger ducted systems.
Evaporative coolers are cheaper to install than refrigerated systems and need fewer technical components.
Selecting the right system size avoids overspending on installation and prevents future energy waste.
Simple maintenance ensures optimal performance and efficiency over time.
Non-condensing gas heaters require no drainage, easing upkeep for homeowners.
Evaporative systems only need functioning water pumps and clean pads to operate efficiently.
Refrigerated systems require refrigerant refills and have more parts, increasing upkeep costs.
Final Thoughts
Always check the star efficiency rating when comparing heating and cooling systems.
Easier-to-install and maintain units reduce energy usage and long-term costs.
Choosing the most energy-efficient model helps your home reduce carbon footprint while saving money.
