5 Ways to Maximize Your Gas Heater’s Efficiency

As the cooler months roll in across Australia, a reliable gas heater becomes more than just a convenience—it’s a necessity. From chilly Melbourne mornings to crisp Adelaide evenings, gas heaters help maintain a warm, inviting home. However, with rising energy costs and growing awareness of environmental impact, many Australians are now seeking smart solutions to improve gas heater efficiency and make their heating systems more cost-effective and sustainable.

An efficient gas heater doesn’t just keep you warm—it reduces your energy bills, extends the lifespan of your system, and helps minimise your household’s carbon footprint. Whether you’re using a ducted gas heating system or a wall-mounted gas heater, these five strategies will help you get the most out of your investment.

1. Seal and Insulate Your Home: Keep the Warmth In

Before even switching on your gas heater, it’s essential to make sure your home is retaining the heat you’re paying for. In many cases, homes lose up to 25% of internal heat through draughts and poor insulation. The good news? Small adjustments can make a big impact on comfort and efficiency.

How to Minimise Heat Loss:

  • Seal gaps and cracks: Inspect doors, windows, and skirting boards for gaps where air can escape. Use weather stripping, draught excluders, or silicone sealant to block these off.
  • Insulate walls and ceilings: Proper insulation acts as a thermal barrier, keeping your indoor warmth from seeping outside. If your ceiling isn’t insulated, it’s one of the first places to address—heat rises, after all.
  • Use heavy curtains: Thermal-backed curtains can significantly reduce heat loss through windows, particularly single-glazed ones.
  • Close doors to unused rooms: Don’t waste energy heating spaces you’re not using. Shut internal doors and focus your heating on the rooms you’re in.
  • Use door snakes or seals: A simple fabric draught stopper at the base of your doors can prevent a surprising amount of heat from escaping.

These simple, low-cost changes reduce the strain on your gas heater and maintain a warmer environment longer.

2. Use Your Thermostat Wisely: Set It Right and Save

Your thermostat plays a pivotal role in how much energy your gas heater consumes. Making small adjustments to your temperature settings can lead to substantial savings over the heating season.

Thermostat Tips for Energy Efficiency:

  • Set the thermostat between 18°C and 20°C: According to government energy guidelines, this is the ideal balance between comfort and efficiency. For every degree above 20°C, your energy consumption can increase by up to 10–15%.
  • Lower the temperature when away or asleep: If you’re out during the day or tucked into bed under a doona, your heater doesn’t need to run at full strength. Consider dropping the temperature to 16–17°C during these times.
  • Upgrade to a smart or programmable thermostat: These devices allow you to set heating schedules that align with your lifestyle. No more accidentally leaving the heater on all day—let your thermostat do the thinking for you.
  • Avoid constant on-off cycling: Instead of frequently turning your heater on and off, let your thermostat regulate the temperature steadily. Sudden surges in heating can use more energy than maintaining a consistent warmth.

Optimising your thermostat settings is one of the quickest, easiest ways to control heating costs without sacrificing comfort.

3. Regular Maintenance: Keep Your Heater in Top Condition

Routine maintenance is key to ensuring your gas heater remains safe, efficient, and long-lasting. Dust, debris, and worn components can reduce airflow, strain the system, and even lead to dangerous carbon monoxide leaks. Regular servicing plays a vital role in maintaining gas heater efficiency, helping your system operate at peak performance while lowering energy consumption and extending its lifespan.

Essential Maintenance Tips:

  • Clean or replace filters: Clogged filters make your system work harder and use more energy. Check them every 1–3 months, especially during heavy usage periods.
  • Inspect vents and registers: Make sure nothing is blocking airflow, such as furniture or dust buildup. Unobstructed airflow improves heat distribution and efficiency.
  • Listen for strange sounds: Rattling, humming, or clicking noises may indicate worn parts or loose connections. Don’t ignore unusual sounds—they’re early warning signs.
  • Book a professional gas heater service: Experts recommend servicing your gas heater at least once every two years, or annually if it’s heavily used. A licensed gas fitter will inspect burners, test carbon monoxide levels, and ensure everything is running at peak performance.

4. Utilise Ceiling Fans: Circulate Warm Air Effectively

It might seem counterintuitive, but your ceiling fan can be a valuable ally during winter. Hot air naturally rises, which means the warmth generated by your gas heater can end up near the ceiling instead of where you need it—around you.

How to Use Fans in Winter:

  • Reverse the fan direction: Most ceiling fans have a switch to reverse the blade rotation. In winter, set the blades to rotate clockwise at a low speed. This gently pushes the trapped warm air back down without creating a breeze.
  • Use in open-plan spaces: Ceiling fans are particularly effective in open-plan living areas where heat can accumulate near the roof.
  • Pair with ducted heating: Fans help distribute warm air from central heating systems more evenly, reducing cold spots and allowing you to lower your thermostat slightly.

When used correctly, ceiling fans help make your home feel warmer without using additional energy.

5. Optimise Natural Heat Sources: Let the Sun Shine In

One of the most effective ways to improve heating efficiency is also the simplest—make the most of natural sunlight. By using the sun’s warmth strategically, you can ease the workload on your gas heater.

Harness Solar Warmth:

  • Open curtains and blinds during the day: Let in as much sunlight as possible, especially on north-facing windows. Sunlight warms the home naturally and reduces the need for artificial heating.
  • Close curtains at dusk: As soon as the sun sets, close your window coverings to trap the heat and prevent warm air from escaping.
  • Use thermal-backed curtains: These help reduce heat loss by up to 40% through windows, especially older ones that lack double glazing.
  • Keep windows clean: A layer of dust or grime can reduce the effectiveness of sunlight in warming your home. Clean windows maximise solar gain.

Leveraging the sun is not only energy-smart—it’s free.

Bonus Tip: Choose Energy-Efficient Gas Heaters

When it’s time to upgrade your system, selecting the right gas heater can make a world of difference. In Australia, gas heaters are rated using the Energy Rating Label (Star Rating System), which helps consumers compare the efficiency of different models.

What to Look For:

  • Higher star rating = greater efficiency: More stars mean the heater uses less gas to produce the same amount of heat.
  • Models that meet Australian Standards: Always check for compliance to ensure safety and performance.
  • Long-term cost savings: While high-efficiency models may cost more upfront, the lower running costs make them more economical over time.

Rebates: What to Know About SA REPS & VIC VEU SA REPS (South Australia)

In South Australia, the SA REPS (Retailer Energy Productivity Scheme) offers rebates to help households and businesses reduce energy consumption. These incentives commonly apply to the installation of energy-efficient gas heaters or replacing outdated systems with high-efficiency models. While routine maintenance and servicing are not always covered, some service work may be eligible if bundled with a qualifying upgrade.

In Victoria, the VEU (Victorian Energy Upgrades) program supports efforts to lower greenhouse gas emissions through appliance upgrades. Rebates typically apply to the installation of high-efficiency heating and cooling systems or gas heater replacements. However, standalone servicing is generally not covered unless it’s part of a broader efficiency project. To find out if your gas heater service is eligible, it’s best to contact Rite Price Heating & Cooling directly and ask if they partner with accredited providers under SA REPS or VEU who can apply the rebate on your behalf.
